189-529: Gaganyaan ( [ɡəɡənəjɑːnə] ; pronunciation from Sanskrit : gagana , "celestial" and yāna , "craft, vehicle") is an Indian crewed orbital spacecraft intended to be the formative spacecraft of the Indian Human Spaceflight Programme . The spacecraft is being designed to carry three people, and a planned upgraded version will be equipped with rendezvous and docking capabilities. In its maiden crewed mission,

378-736: A launch vehicle (carrier rocket). On a sub-orbital spaceflight , a space vehicle enters space and then returns to the surface without having gained sufficient energy or velocity to make a full Earth orbit . For orbital spaceflights , spacecraft enter closed orbits around the Earth or around other celestial bodies . Spacecraft used for human spaceflight carry people on board as crew or passengers from start or on orbit ( space stations ) only, whereas those used for robotic space missions operate either autonomously or telerobotically . Robotic spacecraft used to support scientific research are space probes . Robotic spacecraft that remain in orbit around

567-599: A 15.2 metres (50 ft) CanadaArm1 , an upgraded version of which is used on the International Space Station . The heat shield (or Thermal Protection System ) of the orbiter, used to protect it from extreme levels of heat during atmospheric reentry and the cold of space, was made up of different materials depending on weight and how much heating a particular area on the shuttle would receive during reentry, which ranged from over 2,900 °F (1,600 °C) to under 700 °F (370 °C). The orbiter

756-886: A 5-metre (16 ft) diameter payload fairing was used to be able to accommodate large modules like space station segments. The aerodynamic characterization research was conducted at the National Aerospace Laboratories ' 1.2m Trisonic Wind Tunnel Facility. Furthermore, a number of changes to make safety-critical subsystems reliable are planned for lower operating margins, redundancy, stringent qualification requirements, revaluation and strengthening of components. Avionics improvements includes an Integrated Health Monitoring System (LVHM), Dual chain Telemetry & Telecommand Processor (TTCP) and Quad-redundant Navigation and Guidance Computer (NGC). The High Thrust Vikas engines (HTVE) of L110 core stage will operate at

945-563: A blunt shape, do not usually contain much more fuel than needed, and they do not possess wings unlike spaceplanes . They are the simplest form of recoverable spacecraft, and so the most commonly used. The first such capsule was the Vostok capsule built by the Soviet Union, that carried the first person in space, Yuri Gagarin . Other examples include the Soyuz and Orion capsules, built by

1134-573: A chamber pressure of 58.5 bar instead of 62 bar and the Human rated S200 boosters (HS200) will operate at chamber pressure of 55.5 bar instead of 58.8 bar. Segment joints will have three O-rings each. Electro mechanical actuators and digital stage controllers will be employed in all stages of launch vehicle. Gaganyaan's green propellant development was confirmed by K. Sivan , and it will be used in all stages of HLVM3. In order to stop rocket engines from emitting chlorinated exhaust products, ISRO has started

1323-683: A dead language in the most common usage of the term. Pollock's notion of the "death of Sanskrit" remains in this unclear realm between academia and public opinion when he says that "most observers would agree that, in some crucial way, Sanskrit is dead." Spacecraft A spacecraft is a vehicle that is designed to fly and operate in outer space . Spacecraft are used for a variety of purposes, including communications , Earth observation , meteorology , navigation , space colonization , planetary exploration , and transportation of humans and cargo . All spacecraft except single-stage-to-orbit vehicles cannot get into space on their own, and require

1512-544: A flight suit developed by Defence Bioengineering and Electromedical Laboratory (DEBEL) and the powerful LVM3 launch vehicle. Having met all required technological keystones, the Indian Human Spaceflight Programme was accepted and formally announced by the Prime Minister Narendra Modi on 15 August 2018. Gaganyaan will be the first crewed spacecraft under this programme. To begin the training of doctors and engineers for space mission, Brigitte Godard,

1701-658: A flight surgeon affiliated with the European Space Agency , traveled to India in 2018. ISRO 's Human Space Flight Centre and Glavcosmos , which is a subsidiary of the Russian state corporation Roscosmos , signed an agreement on 1 July 2019, for cooperation in the selection, support, medical examination and space training of Indian astronauts. An ISRO Technical Liaison Unit (ITLU) has been approved to be set up in Moscow for coordination. In 2021, ISRO established

1890-433: A focus on Indian philosophies and Sanskrit. Though written in a number of different scripts, the dominant language of Hindu texts has been Sanskrit. It or a hybrid form of Sanskrit became the preferred language of Mahayana Buddhism scholarship; for example, one of the early and influential Buddhist philosophers, Nagarjuna (~200 CE), used Classical Sanskrit as the language for his texts. According to Renou, Sanskrit had

2079-591: A language competed with numerous, less exact vernacular Indian languages called Prakritic languages ( prākṛta - ). The term prakrta literally means "original, natural, normal, artless", states Franklin Southworth . The relationship between Prakrit and Sanskrit is found in Indian texts dated to the 1st millennium CE. Patañjali acknowledged that Prakrit is the first language, one instinctively adopted by every child with all its imperfections and later leads to

2268-554: A liftoff thrust of 2,800,000 pounds-force (12 MN), which soon increased to 3,300,000 pounds-force (15 MN) per booster, and were fueled by a combination of PBAN and APCP , the Space Shuttle Orbiter , with 3 RS-25 engines that used a liquid oxygen / liquid hydrogen propellant combination, and the bright orange throwaway Space Shuttle external tank from which the RS-25 engines sourced their fuel. The orbiter

2457-658: A limited role in the Theravada tradition (formerly known as the Hinayana) but the Prakrit works that have survived are of doubtful authenticity. Some of the canonical fragments of the early Buddhist traditions, discovered in the 20th century, suggest the early Buddhist traditions used an imperfect and reasonably good Sanskrit, sometimes with a Pali syntax, states Renou. The Mahāsāṃghika and Mahavastu, in their late Hinayana forms, used hybrid Sanskrit for their literature. Sanskrit

2646-454: A natural part of the earliest Vedic language, and that these developed in the centuries after the composition had been completed, and as a gradual unconscious process during the oral transmission by generations of reciters. The primary source for this argument is internal evidence of the text which betrays an instability of the phenomenon of retroflexion, with the same phrases having sandhi-induced retroflexion in some parts but not other. This

2835-479: A negative evidence to Pollock's hypothesis, but it is not positive evidence. A closer look at Sanskrit in the Indian history after the 12th century suggests that Sanskrit survived despite the odds. According to Hanneder, On a more public level the statement that Sanskrit is a dead language is misleading, for Sanskrit is quite obviously not as dead as other dead languages and the fact that it is spoken, written and read will probably convince most people that it cannot be

3024-546: A pan-Indo-Aryan accessibility to information and knowledge in the ancient and medieval times, in contrast to the Prakrit languages which were understood just regionally. It created a cultural bond across the subcontinent. As local languages and dialects evolved and diversified, Sanskrit served as the common language. It connected scholars from distant parts of South Asia such as Tamil Nadu and Kashmir, states Deshpande, as well as those from different fields of studies, though there must have been differences in its pronunciation given

3213-540: A period of seven years, including the ₹ 5,000 crore (US$ 0.7 billion) for the initial work of the crewed spacecraft during the Eleventh Five-Year Plan (2007–2012) out of which the Government released ₹ 50 crore (US$ 7 million) in 2007–2008. In December 2018, the government approved a further ₹ 10,000 crore (US$ 1.5 billion) for a 7-day crewed flight of 3 astronauts to take place by 2021. Expanding

3402-571: A planetary body are artificial satellites . To date, only a handful of interstellar probes , such as Pioneer 10 and 11 , Voyager 1 and 2 , and New Horizons , are on trajectories that leave the Solar System . Orbital spacecraft may be recoverable or not. Most are not. Recoverable spacecraft may be subdivided by a method of reentry to Earth into non-winged space capsules and winged spaceplanes . Recoverable spacecraft may be reusable (can be launched again or several times, like

3591-578: A refined and standardized grammatical form that emerged in the mid-1st millennium BCE and was codified in the most comprehensive of ancient grammars, the Aṣṭādhyāyī ('Eight chapters') of Pāṇini . The greatest dramatist in Sanskrit, Kālidāsa , wrote in classical Sanskrit, and the foundations of modern arithmetic were first described in classical Sanskrit. The two major Sanskrit epics, the Mahābhārata and

3780-417: A rendezvous with Intelsat-901 on 25 February 2020. It will remain with the satellite until 2025 before the satellite is moved to a final graveyard orbit and the vehicle does a rendezvous with another satellite. The other one launched on an Ariane 5 rocket on 15 August 2020. A spacecraft astrionics system comprises different subsystems, depending on the mission profile. Spacecraft subsystems are mounted in

3969-538: A restrained language from which archaisms and unnecessary formal alternatives were excluded". The Classical form of the language simplified the sandhi rules but retained various aspects of the Vedic language, while adding rigor and flexibilities, so that it had sufficient means to express thoughts as well as being "capable of responding to the future increasing demands of an infinitely diversified literature", according to Renou. Pāṇini included numerous "optional rules" beyond

4158-542: A safe landing. Following three uncrewed orbital flight demonstrations of the spacecraft, a crewed Gaganyaan is slated to be launched on the HLVM3 (Human-rated version of LVM3 ) launcher. While the LVM3 is being human rated for Gaganyaan project, the rocket was designed with potential human spaceflight applications in consideration. The maximum acceleration during ascent phase of flight was limited to 4 Gs for crew comfort and

4347-439: A similar phonetic structure to Tamil. Hock et al. quoting George Hart state that there was influence of Old Tamil on Sanskrit. Hart compared Old Tamil and Classical Sanskrit to arrive at a conclusion that there was a common language from which these features both derived – "that both Tamil and Sanskrit derived their shared conventions, metres, and techniques from a common source, for it is clear that neither borrowed directly from

4536-678: A spacecraft of their own, the CST-100 , commonly referred to as Starliner , but a crewed flight is yet to occur. China developed, but did not fly Shuguang , and is currently using Shenzhou (its first crewed mission was in 2003). Except for the Space Shuttle and the Buran spaceplane of the Soviet Union, the latter of which only ever had one uncrewed test flight, all of the recoverable crewed orbital spacecraft were space capsules . The International Space Station , crewed since November 2000,

4725-663: A temporary ground station for the Gaganyaan mission in the Cocos (Keeling) Islands , following an extended dialogue with the Australian Space Agency . ISRO has plans to build a permanent ground station for the project there. To gain practical space medicine experience, ISRO is sending two flight surgeons specialized in aviation medicine from the Indian Air Force to Russia in 2021. They are in charge of

4914-458: Is 3.2 meters in diameter, 8.5 meters long, and 5.5 tons in weight. The human-rated variant of the S200 solid strap-on booster, or 'HS200', was developed for the Gaganyaan programme in collaboration with Larsen & Toubro. The first static fire test of HS200 was conducted on 13 May 2022 at Satish Dhawan Space Centre (SDSC) for a duration of 135 seconds, carrying 203 tons of solid propellant. During

5103-652: Is a joint venture between Russia, the United States, Canada and several other countries. Uncrewed spacecraft are spacecraft without people on board. Uncrewed spacecraft may have varying levels of autonomy from human input; they may be remote controlled , remote guided or even autonomous , meaning they have a pre-programmed list of operations, which they will execute unless otherwise instructed. Many space missions are more suited to telerobotic rather than crewed operation, due to lower cost and lower risk factors. In addition, some planetary destinations such as Venus or

5292-516: Is akin to that of Latin and Ancient Greek in Europe. Sanskrit has significantly influenced most modern languages of the Indian subcontinent , particularly the languages of the northern, western, central and eastern Indian subcontinent. Sanskrit declined starting about and after the 13th century. This coincides with the beginning of Islamic invasions of South Asia to create, and thereafter expand

5481-543: Is already working on a monopropellant blended formulation consisting of hydroxylammonium nitrate (HAN), ammonium nitrate , methanol and water . Many of the fundamental technologies were realized by ISRO by the time Gaganyaan was approved by the Union Cabinet. After receiving approval, many of them were human-rated to make sure their dependability satisfied the requirements needed for human spaceflight. Space Capsule Recovery Experiment II (SRE-2), an extension of

5670-443: Is an artificial satellite that relays and amplifies radio telecommunication signals via a transponder ; it creates a communication channel between a source transmitter and a receiver at different locations on Earth .

6048-452: Is found in the writing of Bharata Muni , the author of the ancient Natya Shastra text. The early Jain scholar Namisādhu acknowledged the difference, but disagreed that the Prakrit language was a corruption of Sanskrit. Namisādhu stated that the Prakrit language was the pūrvam ('came before, origin') and that it came naturally to children, while Sanskrit was a refinement of Prakrit through "purification by grammar". Sanskrit belongs to

6237-516: Is meant to supplement the continuing human spaceflight programs. The Gaganyaan initiative has received an extra ₹ 11,170 crore (US$ 1.3 billion) in financing to support its expanded scope, bringing the total budget to ₹ 20,193 crore (US$ 2.4 billion). With four missions under the ongoing Gaganyaan program scheduled by 2026, the development of the BAS-1 module and four additional missions for technology demonstration and validation by 2028,

6426-724: Is powered by liquid propellant engines . The crew module is mated to the service module, and together they constitute 8.2 t (18,000 lb) orbital module. The Service Module Propulsion System (SMPS) will perform an orbit raising manoeuvre allowing Gaganyaan to reach 400 km in low Earth orbit (LEO), then remain docked during a deorbit burn until atmospheric reentry . It will use an unified bipropellant system consisting of MON-3 and Monomethylhydrazine as oxidizer and fuel, having five main engines derived from ISRO's liquid apogee motor with 440 N (99 lb f ) thrust and sixteen 100 N reaction control system (RCS) thrusters . On 11 August 2022, ISRO successfully completed

6615-532: Is rare in the later version of the language. The Homerian Greek, like Ṛg-vedic Sanskrit, deploys simile extensively, but they are structurally very different. The early Vedic form of the Sanskrit language was far less homogenous compared to the Classical Sanskrit as defined by grammarians by about the mid-1st millennium BCE. According to Richard Gombrich—an Indologist and a scholar of Sanskrit, Pāli and Buddhist Studies—the archaic Vedic Sanskrit found in

6804-479: Is taken along with evidence of controversy, for example, in passages of the Aitareya-Āraṇyaka (700 BCE), which features a discussion on whether retroflexion is valid in particular cases. The Ṛg-veda is a collection of books, created by multiple authors. These authors represented different generations, and the mandalas 2 to 7 are the oldest while the mandalas 1 and 10 are relatively the youngest. Yet,

6993-526: Is the height required by the international organization Fédération Aéronautique Internationale to count as a spaceflight. This altitude is called the Kármán line . In particular, in the 1940s there were several test launches of the V-2 rocket , some of which reached altitudes well over 100 km. As of 2016, only three nations have flown crewed spacecraft: USSR/Russia, USA, and China. The first crewed spacecraft

7182-589: Is the predominant language of one of the largest collection of historic manuscripts. The earliest known inscriptions in Sanskrit are from the 1st century BCE, such as the Ayodhya Inscription of Dhana and Ghosundi-Hathibada (Chittorgarh) . Though developed and nurtured by scholars of orthodox schools of Hinduism, Sanskrit has been the language for some of the key literary works and theology of heterodox schools of Indian philosophies such as Buddhism and Jainism. The structure and capabilities of

7371-626: Is to be replaced by expendable rockets such as the Space Launch System and ULA 's Vulcan rocket, as well as the commercial launch vehicles. Scaled Composites ' SpaceShipOne was a reusable suborbital spaceplane that carried pilots Mike Melvill and Brian Binnie on consecutive flights in 2004 to win the Ansari X Prize . The Spaceship Company built a successor SpaceShipTwo . A fleet of SpaceShipTwos operated by Virgin Galactic

7560-540: The Bhagavata Purana , the Panchatantra and many other texts are all in the Sanskrit language. The Classical Sanskrit with its exacting grammar was thus the language of the Indian scholars and the educated classes, while others communicated with approximate or ungrammatical variants of it as well as other natural Indian languages. Sanskrit, as the learned language of Ancient India, thus existed alongside

7938-580: The Dalai Lama , the Sanskrit language is a parent language that is at the foundation of many modern languages of India and the one that promoted Indian thought to other distant countries. In Tibetan Buddhism, states the Dalai Lama, Sanskrit language has been a revered one and called legjar lhai-ka or "elegant language of the gods". It has been the means of transmitting the "profound wisdom of Buddhist philosophy" to Tibet. The Sanskrit language created

8127-549: The Deep Space Network . A space telescope or space observatory is a telescope in outer space used to observe astronomical objects. Space telescopes avoid the filtering and distortion of electromagnetic radiation which they observe, and avoid light pollution which ground-based observatories encounter. They are divided into two types: satellites which map the entire sky ( astronomical survey ), and satellites which focus on selected astronomical objects or parts of

8316-609: The Department of Biotechnology and the ISRO have signed a memorandum of understanding (MoU) on 25 October 2024 to collaborate on space biotechnology research. The application will be in ISRO's human space flight project, Gaganyaan. The MoU will address problems like food storage, radiation, microgravity, and constant nutrient supply, as well as health risks like cancer, cataracts , and loss of bone and muscle. A crewed spacecraft would require about ₹ 12,400 crore (US$ 1.77 billion) over

The first crewed mission was originally planned to be launched on ISRO's HLVM3 rocket in December 2021. As of November 2024, it is expected to be launched no earlier than 2026. The Hindustan Aeronautics Limited (HAL)-manufactured crew module underwent its first uncrewed experimental flight on 18 December 2014. As of May 2019, design of

8694-675: The Indo-European family of languages . It is one of the three earliest ancient documented languages that arose from a common root language now referred to as Proto-Indo-European : Other Indo-European languages distantly related to Sanskrit include archaic and Classical Latin ( c. 600 BCE–100 CE, Italic languages ), Gothic (archaic Germanic language , c.  350 CE ), Old Norse ( c. 200 CE and after), Old Avestan ( c.  late 2nd millennium BCE ) and Younger Avestan ( c. 900 BCE). The closest ancient relatives of Vedic Sanskrit in

8883-409: The International Space Station and Tiangong space station. Some spacecrafts can operate as both a crewed and uncrewed spacecraft. For example, the Buran spaceplane could operate autonomously but also had manual controls, though it never flew with crew onboard. Other dual crewed/uncrewed spacecrafts include: SpaceX Dragon 2 , Dream Chaser , and Tianzhou . A communications satellite

With an emphasis on microgravity research, space biomanufacturing , bioastronautics , and astrobiology ,

9450-753: The Rigveda had already evolved in the Vedic period, as evidenced in the later Vedic literature. Gombrich posits that the language in the early Upanishads of Hinduism and the late Vedic literature approaches Classical Sanskrit, while the archaic Vedic Sanskrit had by the Buddha 's time become unintelligible to all except ancient Indian sages. The formalization of the Saṃskṛta language is credited to Pāṇini , along with Patañjali's Mahābhāṣya and Katyayana's commentary that preceded Patañjali's work. Panini composed Aṣṭādhyāyī ('Eight-Chapter Grammar'), which became

9639-531: The Rāmāyaṇa , however, were composed in a range of oral storytelling registers called Epic Sanskrit which was used in northern India between 400 BCE and 300 CE, and roughly contemporary with classical Sanskrit. In the following centuries, Sanskrit became tradition-bound, stopped being learned as a first language, and ultimately stopped developing as a living language. The hymns of the Rigveda are notably similar to

Others form satellite constellations in low Earth orbit , where antennas on the ground have to follow the position of the satellites and switch between satellites frequently. The high frequency radio waves used for telecommunications links travel by line of sight and so are obstructed by

10773-406: The sandhi rules, both internal and external. Quite many words found in the early Vedic Sanskrit language are never found in late Vedic Sanskrit or Classical Sanskrit literature, while some words have different and new meanings in Classical Sanskrit when contextually compared to the early Vedic Sanskrit literature. Arthur Macdonell was among the early colonial era scholars who summarized some of

10962-500: The verbal adjective sáṃskṛta- is a compound word consisting of sáṃ ('together, good, well, perfected') and kṛta - ('made, formed, work'). It connotes a work that has been "well prepared, pure and perfect, polished, sacred". According to Biderman, the perfection contextually being referred to in the etymological origins of the word is its tonal—rather than semantic—qualities. Sound and oral transmission were highly valued qualities in ancient India, and its sages refined

A Docking Adaptor called Bhartiya Docking System is currently under development. The Gaganyaan Spacecraft will have a 2.9 t (6,400 lb) service module

13419-492: The Indian Human Spaceflight project. With extra facilities needed for launch escape systems . Russia is likely to provide astronaut training. In Spring 2009, the full-scale mock-up of the crew capsule of Gaganyaan was built and delivered to Satish Dhawan Space Center for the training of astronauts. India has already successfully developed and tested several building blocks, including re-entry space capsule , pad abort test , safe crew ejection mechanism in case of rocket failure,

13608-476: The Indo-Aryan language underwent rapid linguistic change and morphed into the Vedic Sanskrit language. The pre-Classical form of Sanskrit is known as Vedic Sanskrit . The earliest attested Sanskrit text is the Rigveda , a Hindu scripture from the mid- to late-second millennium BCE. No written records from such an early period survive, if any ever existed, but scholars are generally confident that

13797-519: The Indo-European languages are the Nuristani languages found in the remote Hindu Kush region of northeastern Afghanistan and northwestern Himalayas, as well as the extinct Avestan and Old Persian – both are Iranian languages . Sanskrit belongs to the satem group of the Indo-European languages. Colonial era scholars familiar with Latin and Greek were struck by the resemblance of

13986-421: The Moon, Mars, and potentially beyond. It is intended to enable long duration interplanetary flights for a crew of up to 100 people. It will also be capable of point-to-point transport on Earth, enabling travel to anywhere in the world in less than an hour. Furthermore, the spacecraft will be used to refuel other Starship vehicles to allow them to reach higher orbits to and other space destinations. Elon Musk ,

14175-532: The Muslim rule in the form of Sultanates, and later the Mughal Empire . Sheldon Pollock characterises the decline of Sanskrit as a long-term "cultural, social, and political change". He dismisses the idea that Sanskrit declined due to "struggle with barbarous invaders", and emphasises factors such as the increasing attractiveness of vernacular language for literary expression. With the fall of Kashmir around

14364-555: The Muslim rulers. Hindu rulers such as Shivaji of the Maratha Empire , reversed the process, by re-adopting Sanskrit and re-asserting their socio-linguistic identity. After Islamic rule disintegrated in South Asia and the colonial rule era began, Sanskrit re-emerged but in the form of a "ghostly existence" in regions such as Bengal. This decline was the result of "political institutions and civic ethos" that did not support

14553-501: The SMPS with success. The thrusters were run in tandem with the mission profile, both in continuous and pulsed mode. The first hot test, which lasted 723.60 seconds, was intended to show how to pump fuel into the orbital module and burn 100 Newton thrusters and LAM engines for calibration. The calibration burn was essential to identify and isolate any non-operational engines. The RCS thrusters and LAM engines operated as anticipated. The goal of

14742-471: The SMPS. The combined performance of SMPS was showcased in the first hot test of the Phase-2 test series. Each 440 Newton thrust engine will also be tested individually for longer duration involving various parameters to gain human-rating certification . ISRO has scheduled five additional tests to demonstrate both nominal and off-nominal mission scenarios. On 26 July 2023, ISRO conducted two more hot tests on

14931-488: The Salyut 7. He conducted an Earth observation program concentrating on India . He also did life sciences and materials processing experiments, including silicium fusing tests. To commemorate the occasion special stamps and first day covers were released by the Government of India and Soviet Union. Preliminary studies and technological development of Gaganyaan started in 2006 under the generic name "Orbital Vehicle". The plan

15120-499: The Saṃskṛta language, both in its vocabulary and grammar, to the classical languages of Europe. In The Oxford Introduction to Proto-Indo-European and the Proto-Indo-European World , Mallory and Adams illustrate the resemblance with the following examples of cognate forms (with the addition of Old English for further comparison): The correspondences suggest some common root, and historical links between some of

15309-585: The Service Module Propulsion System (SMPS), which will be incorporated into the Gaganyaan spacecraft, was successfully tested by ISRO on 28 August 2021. The service module is designed and developed by Liquid Propulsion Systems Centre (LPSC). At the ISRO Propulsion Complex (IPRC), the system demonstration model was fired for 450 seconds. The performance met the pre-test prediction model. The propulsion system for

15498-500: The Solar System , these are Voyager 1 , Voyager 2 , Pioneer 10 , Pioneer 11 , and New Horizons . The identical Voyager probes , weighing 721.9 kilograms (1,592 lb), were launched in 1977 to take advantage of a rare alignment of Jupiter , Saturn , Uranus and Neptune that would allow a spacecraft to visit all four planets in one mission, and get to each destination faster by using gravity assist . In fact,

15687-638: The South India, such as the great Vijayanagara Empire , so did Sanskrit. There were exceptions and short periods of imperial support for Sanskrit, mostly concentrated during the reign of the tolerant Mughal emperor Akbar . Muslim rulers patronized the Middle Eastern language and scripts found in Persia and Arabia, and the Indians linguistically adapted to this Persianization to gain employment with

15876-517: The Soviet Union and NASA , respectively. Spaceplanes are spacecraft that are built in the shape of, and function as, airplanes . The first example of such was the North American X-15 spaceplane, which conducted two crewed flights which reached an altitude of over 100 kilometres (62 mi) in the 1960s. This first reusable spacecraft was air-launched on a suborbital trajectory on July 19, 1963. The first reusable orbital spaceplane

16065-606: The Soviet rocket Soyuz T-11 launched from Baikonur Cosmodrome in the Kazakh Soviet Socialist Republic on 3 April 1984. The Soyuz T-11 spacecraft carrying cosmonauts including Sharma docked and transferred the three member Soviet-Indian international crew, consisting of the ship's commander, Yury Malyshev , and flight engineer, Gennadi Strekalov , to the Salyut 7 Orbital Station. Sharma spent 7   days, 21   hours, and 40   minutes aboard

16254-554: The Sputnik launch was a single event, it marked the start of the Space Age . Apart from its value as a technological first, Sputnik 1 also helped to identify the upper atmospheric layer 's density, by measuring the satellite's orbital changes. It also provided data on radio -signal distribution in the ionosphere . Pressurized nitrogen in the satellite's false body provided the first opportunity for meteoroid detection. Sputnik 1

16443-521: The Sun as of August 2023. NASA provides real time data of their distances and data from the probe’s cosmic ray detectors. Because of the probe’s declining power output and degradation of the RTGs over time, NASA has had to shut down certain instruments to conserve power. The probes may still have some scientific instruments on until the mid-2020s or perhaps the 2030s. After 2036, they will both be out of range of

16632-447: The Vedic Sanskrit in these books of the Ṛg-veda "hardly presents any dialectical diversity", states Louis Renou – an Indologist known for his scholarship of the Sanskrit literature and the Ṛg-veda in particular. According to Renou, this implies that the Vedic Sanskrit language had a "set linguistic pattern" by the second half of the 2nd millennium BCE. Beyond the Ṛg-veda, the ancient literature in Vedic Sanskrit that has survived into

16821-451: The Vedic Sanskrit's bahulam framework, to respect liberty and creativity so that individual writers separated by geography or time would have the choice to express facts and their views in their own way, where tradition followed competitive forms of the Sanskrit language. The phonetic differences between Vedic Sanskrit and Classical Sanskrit, as discerned from the current state of the surviving literature, are negligible when compared to

17010-506: The acceptance of liquid oxygen/ liquid hydrogen and LOX /kerosene based propulsion systems for launch vehicles, ISRO has already started the transition towards environmentally benign and green propellants. Currently in use in the cryogenic upper stages of the GSLV and LVM3 is the LOX/ LH2 mix. In place of traditional hydrazine , ISRO developed ISROSENE, a rocket grade version of kerosene. In

17199-461: The actual crew module mass was taken to an altitude of 2.5 km and dropped from Ilyushin Il-76 by Indian Air Force . Two small pyro-based mortar-deployed pilot parachutes then pulled the main parachutes free. The size of the main parachutes was initially restricted to a smaller area to reduce opening shock. After 7 seconds, the pyro-based reefing line cutters cut the area restricting line, allowing

17388-459: The alphabet, the structure of words, and its exacting grammar into a "collection of sounds, a kind of sublime musical mold" as an integral language they called Saṃskṛta . From the late Vedic period onwards, state Annette Wilke and Oliver Moebus, resonating sound and its musical foundations attracted an "exceptionally large amount of linguistic, philosophical and religious literature" in India. Sound

17577-471: The ascent phase for the Orbital Module. On 20 July 2023, hot test was conducted in final configuration of SMPS in which sixteen RCS thrusters with 100 Newton thrust and five LAM engines with 440 Newton thrust were used. The propellant tank feed system, helium pressurization system, flight-qualified thrusters, and control components were all included in the hot test which simulated the fluid circuit of

17766-521: The back of a Boeing 747 SCA and gliding to deadstick landings at Edwards AFB, California . The first Space Shuttle to fly into space was Columbia , followed by Challenger , Discovery , Atlantis , and Endeavour . Endeavour was built to replace Challenger when it was lost in January 1986. Columbia broke up during reentry in February 2003. The first autonomous reusable spaceplane

17955-467: The building of an astronaut training facility in Bangaluru . Gaganyaan crew module is a fully autonomous 5.3 t (12,000 lb) spacecraft designed to carry a 3-member crew to orbit and safely return to the Earth after a mission duration of up to seven days. The crew module is equipped with two parachutes for redundancy, with one parachute enough for a safe splashdown. The parachutes would reduce

18144-440: The capacity to understand the old Prakrit languages such as Ardhamagadhi . A section of European scholars state that Sanskrit was never a spoken language. However, evidences shows that Sanskrit was a spoken language, essential for oral tradition that preserved the vast number of Sanskrit manuscripts from ancient India. The textual evidence in the works of Yaksa, Panini, and Patanajali affirms that Classical Sanskrit in their era

18333-527: The close relationship between the Indo-Iranian tongues and the Baltic and Slavic languages , vocabulary exchange with the non-Indo-European Uralic languages , and the nature of the attested Indo-European words for flora and fauna. The pre-history of Indo-Aryan languages which preceded Vedic Sanskrit is unclear and various hypotheses place it over a fairly wide limit. According to Thomas Burrow, based on

18522-614: The context of a speech or language, is found in verses 5.28.17–19 of the Ramayana . Outside the learned sphere of written Classical Sanskrit, vernacular colloquial dialects ( Prakrits ) continued to evolve. Sanskrit co-existed with numerous other Prakrit languages of ancient India. The Prakrit languages of India also have ancient roots and some Sanskrit scholars have called these Apabhramsa , literally 'spoiled'. The Vedic literature includes words whose phonetic equivalent are not found in other Indo-European languages but which are found in

18711-483: The contract. On 7 December 2022, The Hindu reported that the crew module had entered the production stage. Following fruitless attempts to obtain the Environmental Control and Life Support System (ECLSS) from other countries, ISRO has declared that it will be developing it on its own for Gaganyaan mission. According to ISRO Chairman S Somanath , ISRO has no experience in producing ECLSS, but it

18900-482: The core stage of LVM 3 . Sanskrit Sanskrit ( / ˈ s æ n s k r ɪ t / ; attributively 𑀲𑀁𑀲𑁆𑀓𑀾𑀢𑀁 , संस्कृत- , saṃskṛta- ; nominally संस्कृतम् , saṃskṛtam , IPA: [ˈsɐ̃skr̩tɐm] ) is a classical language belonging to the Indo-Aryan branch of the Indo-European languages . It arose in South Asia after its predecessor languages had diffused there from

19089-464: The crew module and lowering its velocity to a safe level during re-entry, were deployed as part of this test. Pyrotechnic devices called mortars are developed to launch parachutes into the air upon command. With a diameter of 5.8 meters, these conical ribbon-type parachutes use a single-stage reefing system that reduces canopy area and lessens opening stress to provide a controlled and smooth descent. A variety of real-world conditions were recreated during

19278-414: The crew module has been completed. Defence Research and Development Organisation (DRDO) will provide support for critical human-centric systems and technologies such as space-grade food, crew healthcare, radiation measurement and protection, parachutes for the safe recovery of the crew module, and the fire suppression system. The Gaganyaan Mission will be led by V. R. Lalithambika , the former Director of

19467-653: The crystallization of Classical Sanskrit. As in this period the Indo-Aryan tribes had not yet made contact with the inhabitants of the South of the subcontinent, this suggests a significant presence of Dravidian speakers in North India (the central Gangetic plain and the classical Madhyadeśa) who were instrumental in this substratal influence on Sanskrit. Extant manuscripts in Sanskrit number over 30 million, one hundred times those in Greek and Latin combined, constituting

19656-462: The curve of the Earth. The purpose of communications satellites is to relay the signal around the curve of the Earth allowing communication between widely separated geographical points. Communications satellites use a wide range of radio and microwave frequencies . To avoid signal interference, international organizations have regulations for which frequency ranges or "bands" certain organizations are allowed to use. This allocation of bands minimizes

19845-434: The deceleration system of the Gaganyaan crew module. The two apex cover separation parachutes are deployed first in the process, and two drogue parachutes are deployed when stability is accomplished. The mission enters the extraction phase once the drogue parachutes are released. Three pilot parachutes separately remove the three main parachutes, which is a crucial step in lowering the Crew Module's speed to acceptable levels for

20034-467: The detailed and sophisticated treatise then transmitted it through his students. Modern scholarship generally accepts that he knew of a form of writing, based on references to words such as Lipi ('script') and lipikara ('scribe') in section 3.2 of the Aṣṭādhyāyī . The Classical Sanskrit language formalized by Pāṇini, states Renou, is "not an impoverished language", rather it is "a controlled and

20223-434: The development of an environmentally benign solid propellant based on Glycidyl Azide Polymer (GAP) as fuel and Ammonium dinitramide (ADN) as oxidizer. Green propellant combinations including hydrogen peroxide , kerosene , liquid oxygen , liquid methane , ADN-methanol-water, ADN-glycerol-water are all part of the technology demonstration projects that ISRO is conducting. With the use of electric propulsion for spacecraft and

20412-471: The differences between the Vedic and Classical Sanskrit. Louis Renou published in 1956, in French, a more extensive discussion of the similarities, the differences and the evolution of the Vedic Sanskrit within the Vedic period and then to the Classical Sanskrit along with his views on the history. This work has been translated by Jagbans Balbir. The earliest known use of the word Saṃskṛta (Sanskrit), in

20601-480: The different orbiters had differing weights and thus payloads, with Columbia being the heaviest orbiter, Challenger being lighter than Columbia but still heavier than the other three. The orbiter structure was mostly composed of aluminium alloy. The orbiter had seven seats for crew members, though on STS-61-A the launch took place with 8 crew onboard. The orbiters had 4.6 metres (15 ft) wide by 18 metres (59 ft) long payload bays and also were equipped with

20790-460: The distant major ancient languages of the world. The Indo-Aryan migrations theory explains the common features shared by Sanskrit and other Indo-European languages by proposing that the original speakers of what became Sanskrit arrived in South Asia from a region of common origin, somewhere north-west of the Indus region , during the early 2nd millennium BCE. Evidence for such a theory includes

20979-548: The first language of the respective speakers. The Sanskrit language brought Indo-Aryan speaking people together, particularly its elite scholars. Some of these scholars of Indian history regionally produced vernacularized Sanskrit to reach wider audiences, as evidenced by texts discovered in Rajasthan, Gujarat, and Maharashtra. Once the audience became familiar with the easier to understand vernacularized version of Sanskrit, those interested could graduate from colloquial Sanskrit to

21168-412: The foundation of Vyākaraṇa, a Vedānga . The Aṣṭādhyāyī was not the first description of Sanskrit grammar, but it is the earliest that has survived in full, and the culmination of a long grammatical tradition that Fortson says, is "one of the intellectual wonders of the ancient world". Pāṇini cites ten scholars on the phonological and grammatical aspects of the Sanskrit language before him, as well as

21357-410: The general spacecraft categories. This is a list of these spacecraft. Starship is a spacecraft and second stage under development by American aerospace company SpaceX . Stacked atop its booster, Super Heavy , it composes the identically named Starship super heavy-lift space vehicle . The spacecraft is designed to transport both crew and cargo to a variety of destinations, including Earth orbit,

21546-537: The gods Varuna, Mitra, Indra, and Nasatya found in the earliest layers of the Vedic literature. O Bṛhaspati, when in giving names they first set forth the beginning of Language, Their most excellent and spotless secret was laid bare through love, When the wise ones formed Language with their mind, purifying it like grain with a winnowing fan, Then friends knew friendships – an auspicious mark placed on their language. — Rigveda 10.71.1–4 Translated by Roger Woodard The Vedic Sanskrit found in

21735-577: The ground, the test model for the system demonstration employed only eight 100 Newton thrusters and five 440 Newton engines. On 19 July 2023, ISRO successfully completed the test of Gaganyaan Service Module Propulsion System. Five hot tests totaling 2,750 seconds were conducted by ISRO as part of the Phase-1 test series. Eight 100 Newton RCS thrusters and five 440 Newton liquid apogee motor (LAM) engines were used in Phase 1. The system's hot testing replicated

21924-596: The health of the astronauts prior to, during, and following their space journey. Also, in order to receive training and expand their theoretical expertise, the flight surgeons will visit France. ISRO and CNES announced on April 15, 2021, a space agreement for cooperation in space equipment, consumables, and space medicine. The CNES team at the European Astronaut Centre in Cologne and the Centre for

22113-431: The historic Sanskrit literary culture and the failure of new Sanskrit literature to assimilate into the changing cultural and political environment. Sheldon Pollock states that in some crucial way, "Sanskrit is dead ". After the 12th century, the Sanskrit literary works were reduced to "reinscription and restatements" of ideas already explored, and any creativity was restricted to hymns and verses. This contrasted with

22302-486: The intense change that must have occurred in the pre-Vedic period between the Proto-Indo-Aryan language and Vedic Sanskrit. The noticeable differences between the Vedic and the Classical Sanskrit include the much-expanded grammar and grammatical categories as well as the differences in the accent, the semantics and the syntax. There are also some differences between how some of the nouns and verbs end, as well as

22491-432: The largest cultural heritage that any civilization has produced prior to the invention of the printing press. — Foreword of Sanskrit Computational Linguistics (2009), Gérard Huet, Amba Kulkarni and Peter Scharf Sanskrit has been the predominant language of Hindu texts encompassing a rich tradition of philosophical and religious texts, as well as poetry, music, drama , scientific , technical and others. It

22680-426: The life on another spacecraft. It works by docking to its target spacecraft, then correcting its orientation or orbit. This also allows it to rescue a satellite which is in the wrong orbit by using its own fuel to move its target to the correct orbit. The project is currently managed by Northrop Grumman Innovation Systems. As of 2023, 2 have been launched. The first launched on a Proton rocket on 9 October 2019, and did

22869-455: The life support system will also handle waste products of crew members. Throughout the mission, the thermal control system will maintain the spacecraft's component within permissible temperature limits. The Human Space Flight Center and Glavkosmos signed a deal on 11 March 2020, for the manufacture and supply of individual equipment packages. NPP Zvezda will manufacture customized couch liners and individual seats for Indian astronauts as part of

23058-412: The linguistic expression and sets the standard for the Sanskrit language. Pāṇini made use of a technical metalanguage consisting of a syntax, morphology and lexicon. This metalanguage is organised according to a series of meta-rules, some of which are explicitly stated while others can be deduced. Despite differences in the analysis from that of modern linguistics, Pāṇini's work has been found valuable and

23247-514: The literary works. The Indian tradition, states Winternitz , has favored the learning and the usage of multiple languages from the ancient times. Sanskrit was a spoken language in the educated and the elite classes, but it was also a language that must have been understood in a wider circle of society because the widely popular folk epics and stories such as the Ramayana , the Mahabharata ,

23436-440: The media that Vikram Sarabhai Space Centre in collaboration with Aerial Delivery Research and Development Establishment (ADRDE), a lab under Defence Research & Development Organisation successfully conducted a series of Drogue Parachute Deployment Tests at Rail Track Rocket Sled Facility of Terminal Ballistics Research Laboratory (TBRL), Chandigarh from 8 to 10 August 2023. Drogue parachutes, which are essential for stabilizing

23625-511: The modern age include the Samaveda , Yajurveda , Atharvaveda , along with the embedded and layered Vedic texts such as the Brahmanas , Aranyakas , and the early Upanishads . These Vedic documents reflect the dialects of Sanskrit found in the various parts of the northwestern, northern, and eastern Indian subcontinent. According to Michael Witzel, Vedic Sanskrit was a spoken language of

23814-429: The more advanced Classical Sanskrit. Rituals and the rites-of-passage ceremonies have been and continue to be the other occasions where a wide spectrum of people hear Sanskrit, and occasionally join in to speak some Sanskrit words such as namah . Classical Sanskrit is the standard register as laid out in the grammar of Pāṇini , around the fourth century BCE. Its position in the cultures of Greater India

24003-401: The most advanced analysis of linguistics until the twentieth century. Pāṇini's comprehensive and scientific theory of grammar is conventionally taken to mark the start of Classical Sanskrit. His systematic treatise inspired and made Sanskrit the preeminent Indian language of learning and literature for two millennia. It is unclear whether Pāṇini himself wrote his treatise or he orally created

24192-602: The most archaic poems of the Iranian and Greek language families, the Gathas of old Avestan and Iliad of Homer . As the Rigveda was orally transmitted by methods of memorisation of exceptional complexity, rigour and fidelity, as a single text without variant readings, its preserved archaic syntax and morphology are of vital importance in the reconstruction of the common ancestor language Proto-Indo-European . Sanskrit does not have an attested native script: from around

24381-409: The mountains of what is today northern Afghanistan across northern Pakistan and into northwestern India. Vedic Sanskrit interacted with the preexisting ancient languages of the subcontinent, absorbing names of newly encountered plants and animals; in addition, the ancient Dravidian languages influenced Sanskrit's phonology and syntax. Sanskrit can also more narrowly refer to Classical Sanskrit ,

24570-636: The need for expensive, heavy life support systems (the Apollo crewed Moon landings required the use of the Saturn V rocket that cost over a billion dollars per launch, adjusted for inflation) and so allows for lighter, less expensive rockets. Space probes have visited every planet in the Solar System and Pluto , and the Parker Solar Probe has an orbit that, at its closest point, is in the Sun's chromosphere . There are five space probes that are escaping

24759-435: The northwest in the late Bronze Age . Sanskrit is the sacred language of Hinduism , the language of classical Hindu philosophy , and of historical texts of Buddhism and Jainism . It was a link language in ancient and medieval South Asia, and upon transmission of Hindu and Buddhist culture to Southeast Asia, East Asia and Central Asia in the early medieval era, it became a language of religion and high culture , and of

24948-597: The numbers are thought to signify a wish to be aligned with the prestige of the language. Sanskrit has been taught in traditional gurukulas since ancient times; it is widely taught today at the secondary school level. The oldest Sanskrit college is the Benares Sanskrit College founded in 1791 during East India Company rule . Sanskrit continues to be widely used as a ceremonial and ritual language in Hindu and Buddhist hymns and chants . In Sanskrit,

25137-649: The operation of the flight-qualified thruster, helium pressurization system, propellant tank feed system, and control components. During the test, which lasted 250 seconds, RCS thrusters and LAM engines were used continuously. During the Gaganyaan mission's ascending phase, the RCS thrusters will ensure precise attitude correction, while the LAM engines will supply the primary propulsive force. The SMPS carries out orbit injection, circularization burn, on-orbit control, de-boost maneuvering, and service module based abort if necessary during

25326-403: The oral transmission of the texts is reliable: they are ceremonial literature, where the exact phonetic expression and its preservation were a part of the historic tradition. However some scholars have suggested that the original Ṛg-veda differed in some fundamental ways in phonology compared to the sole surviving version available to us. In particular that retroflex consonants did not exist as

25515-431: The other." Reinöhl further states that there is a symmetric relationship between Dravidian languages like Kannada or Tamil, with Indo-Aryan languages like Bengali or Hindi, whereas the same relationship is not found for non-Indo-Aryan languages, for example, Persian or English: A sentence in a Dravidian language like Tamil or Kannada becomes ordinarily good Bengali or Hindi by substituting Bengali or Hindi equivalents for

25704-562: The parachutes to inflate fully. The fully inflated main parachutes reduced the payload speed to a safe landing speed. The entire sequence lasted about 2–3 minutes. The Parachute Deceleration System is jointly developed by ISRO and DRDO . System design, analytical simulations for parachute deployment, development of ordnance devices for parachute ejection, mechanical assembly, instrumentation and avionics were done by VSSC. In total, five air dropped tests (of 10 parachutes) are planned as part of qualification process. On 8 August 2023, ISRO informed

25893-529: The political elites in some of these regions. As a result, Sanskrit had a lasting impact on the languages of South Asia, Southeast Asia and East Asia, especially in their formal and learned vocabularies. Sanskrit generally connotes several Old Indo-Aryan language varieties. The most archaic of these is the Vedic Sanskrit found in the Rigveda , a collection of 1,028 hymns composed between 1500 BCE and 1200 BCE by Indo-Aryan tribes migrating east from

26082-414: The possible influence of Dravidian on Sanskrit is only one of many items of syntactic assimilation, not least among them the large repertoire of morphological modality and aspect that, once one knows to look for it, can be found everywhere in classical and postclassical Sanskrit". The main influence of Dravidian on Sanskrit is found to have been concentrated in the timespan between the late Vedic period and

26271-439: The previous 1,500 years when "great experiments in moral and aesthetic imagination" marked the Indian scholarship using Classical Sanskrit, states Pollock. Scholars maintain that the Sanskrit language did not die, but rather only declined. Jurgen Hanneder disagrees with Pollock, finding his arguments elegant but "often arbitrary". According to Hanneder, a decline or regional absence of creative and innovative literature constitutes

26460-480: The problems of interpretation and misunderstanding. The purifying structure of the Sanskrit language removes these imperfections. The early Sanskrit grammarian Daṇḍin states, for example, that much in the Prakrit languages is etymologically rooted in Sanskrit, but involves "loss of sounds" and corruptions that result from a "disregard of the grammar". Daṇḍin acknowledged that there are words and confusing structures in Prakrit that thrive independent of Sanskrit. This view

26649-530: The program aims to develop and demonstrate critical technologies for long-duration human space missions. Madhavan Chandradathan , director of Satish Dhawan Space Centre (SDSC), stated that ISRO would need to set up an astronaut training facility in Bangalore . The newly established Human Space Flight Centre (HSFC) will coordinate the IHSF efforts. Existing launch facilities will be upgraded for launches under

26838-499: The project had been reconsidered and was one of the main beneficiaries of a substantial budget increase announced in February 2014. Space Capsule Recovery Experiment ISRO is developing the Gaganyaan orbital vehicle based on the tests performed with their scaled 555 kilograms (1,224 lb) experimental spacecraft from Space Capsule Recovery Experiment (SRE), which was launched and recovered in January 2007. In SRE, an experimental capsule that had been in orbit earlier splashed into

27027-609: The regional Prakrit languages, which makes it likely that the interaction, the sharing of words and ideas began early in the Indian history. As the Indian thought diversified and challenged earlier beliefs of Hinduism, particularly in the form of Buddhism and Jainism , the Prakrit languages such as Pali in Theravada Buddhism and Ardhamagadhi in Jainism competed with Sanskrit in the ancient times. However, states Paul Dundas , these ancient Prakrit languages had "roughly

27216-497: The relationship between various Indo-European languages, the origin of all these languages may possibly be in what is now Central or Eastern Europe, while the Indo-Iranian group possibly arose in Central Russia. The Iranian and Indo-Aryan branches separated quite early. It is the Indo-Aryan branch that moved into eastern Iran and then south into South Asia in the first half of the 2nd millennium BCE. Once in ancient India,

27405-471: The risk of signal interference. Cargo or resupply spacecraft are robotic spacecraft that are designed specifically to carry cargo , possibly to support space stations ' operation by transporting food, propellant and other supplies. Automated cargo spacecraft have been used since 1978 and have serviced Salyut 6 , Salyut 7 , Mir , the International Space Station and Tiangong space station. As of 2023, three different cargo spacecraft are used to supply

27594-519: The rocket that launched the probes (the Titan IIIE ) could not even send the probes to the orbit of Saturn , yet Voyager 1 is travelling at roughly 17 km/s (11 mi/s) and Voyager 2 moves at about 15 km/s (9.3 mi/s) kilometres per second as of 2023. In 2012, Voyager 1 exited the heliosphere, followed by Voyager 2 in 2018. Voyager 1 actually launched 16 days after Voyager 2 but it reached Jupiter sooner because Voyager 2

27783-562: The role of language, the ontological status of painting word-images through sound, and the need for rules so that it can serve as a means for a community of speakers, separated by geography or time, to share and understand profound ideas from each other. These speculations became particularly important to the Mīmāṃsā and the Nyaya schools of Hindu philosophy, and later to Vedanta and Mahayana Buddhism, states Frits Staal —a scholar of Linguistics with

27972-496: The same relationship to Sanskrit as medieval Italian does to Latin". The Indian tradition states that the Buddha and the Mahavira preferred the Prakrit language so that everyone could understand it. However, scholars such as Dundas have questioned this hypothesis. They state that there is no evidence for this and whatever evidence is available suggests that by the start of the common era, hardly anybody other than learned monks had

28161-454: The same way as a spaceship, as they coexist with numerous micro-organisms, and these micro-organisms are also hard to contain within a spaceship or spacesuit. Multiple space probes were sent to study Moon, the planets, the Sun, multiple small Solar System bodies (comets and asteroids). Special class of uncrewed spacecraft is space telescopes , a telescope in outer space used to observe astronomical objects. The first operational telescopes were

28350-599: The scope of the Gaganyaan initiative, the Union Cabinet , led by Prime Minister Narendra Modi , approved on September 18, 2024, the development of the Bharatiya Antariksh Station 's initial module, BAS-1. The launch of the BAS-1 unit is one of the eight missions that are now part of the redesigned Gaganyaan program, which is scheduled for completion by December 2028. Hardware requirements and more unmanned flights are part of this expansion, which

28539-587: The second hot test, which lasted 350 seconds, was to show how the Orbital Module circularizes to reach the final orbit. The RCS thrusters functioned in pulse mode throughout this test, while the LAM engines ran continuously. On 18 November 2022, Vikram Sarabhai Space Centre (VSSC) conducted an Integrated Main Parachute Airdrop Test (IMAT) of the Parachute Deceleration System (PDS), in which 5-ton dummy mass equivalent of

28728-556: The semi-nomadic Aryans . The Vedic Sanskrit language or a closely related Indo-European variant was recognized beyond ancient India as evidenced by the " Mitanni Treaty" between the ancient Hittite and Mitanni people, carved into a rock, in a region that now includes parts of Syria and Turkey. Parts of this treaty, such as the names of the Mitanni princes and technical terms related to horse training, for reasons not understood, are in early forms of Vedic Sanskrit. The treaty also invokes

28917-422: The service module is a single bi-propellant system consists of sixteen 100 Newton thrusters for reaction control system (RCS) and five primary 440 Newton thrust engines, using monomethylhydrazine (MMH) and mixed oxides of nitrogen (MON-3) as the fuel and oxidizer, respectively. Additionally, IPRC is constructing a new facility to test the Service Module Propulsion System. To validate the propulsion system on

29106-504: The shuttle was a rather dangerous system, with fragile heat shielding tiles, some being so fragile that one could easily scrape it off by hand, often having been damaged in many flights. After 30 years in service from 1981 to 2011 and 135 flights, the shuttle was retired from service due to the cost of maintaining the shuttles, and the 3 remaining orbiters (the other two were destroyed in accidents) were prepared to be displayed in museums. Some spacecraft do not fit particularly well into any of

29295-583: The sky and beyond. Space telescopes are distinct from Earth imaging satellites , which point toward Earth for satellite imaging , applied for weather analysis , espionage , and other types of information gathering . A lander is a type of spacecraft that makes a soft landing on the surface of an astronomical body other than Earth . Some landers, such as Philae and the Apollo Lunar Module , land entirely by using their fuel supply, however many landers (and landings of spacecraft on Earth ) use aerobraking , especially for more distant destinations. This involves

29484-615: The social structures such as the role of the poet and the priests, the patronage economy, the phrasal equations, and some of the poetic metres. While there are similarities, state Jamison and Brereton, there are also differences between Vedic Sanskrit, the Old Avestan, and the Mycenaean Greek literature. For example, unlike the Sanskrit similes in the Ṛg-veda, the Old Avestan Gathas lack simile entirely, and it

29673-635: The solid rocket motor. The reverse flow nozzle makes exhaust gas flow in opposite direction in the nozzle region. The objective of this test was to check ballistic parameters, validate motor subsystem performance (and confirm the design margins), evaluate the thermal performance of nozzle liners especially to confirm the ablative characteristics, validate integrity of all interfaces, evaluate the head-end mounted safe arm (HMSA) based ignition system performance, and evaluate side thrust due to misalignment and variation in flow and other functional parameters including flow reversal. A system demonstration model (SDM) of

29862-415: The spacecraft using a fuel burn to change its trajectory so it will pass through a planet (or a moon's) atmosphere. Drag caused by the spacecraft hitting the atmosphere enables it to slow down without using fuel, however this generates very high temperatures and so adds a requirement for a heat shield of some sort. Space capsules are a type of spacecraft that can return from space at least once. They have

30051-417: The speed of the crew module from over 216 m/s (480 mph) to under 11 m/s (25 mph) at splashdown. The space capsule will have life support and environmental control systems. It will be equipped with emergency mission abort capabilities and a Crew Escape System (CES) that can be activated during the first stage or second rocket stage burn. The nose of the original version of the orbital vehicle

30240-651: The strongest electro-mechanical actuators available, complete with many redundancies and safety measures. The enhancement of S200 solid strap-on booster resulted in a decrease in chamber pressure, increased robustness, proof-leakability, and higher margins. Vikas engine variants are used to power the second stage of the Polar Satellite Launch Vehicle (PSLV), boosters and second stage of the Geosynchronous Satellite Launch Vehicle (GSLV) Mark I and II, and also

30429-698: The technology for orbital launches independently from government agencies. The most prominent examples of such companies are SpaceX and Blue Origin . A German V-2 became the first spacecraft when it reached an altitude of 189 km in June 1944 in Peenemünde , Germany. Sputnik 1 was the first artificial satellite . It was launched into an elliptical low Earth orbit (LEO) by the Soviet Union on 4 October 1957. The launch ushered in new political, military, technological, and scientific developments; while

30618-424: The test firing of Low Altitude Escape Motor (LEM) for Crew Escape System. LEM consists of a solid rocket motor with four reverse flow nozzles that generates maximum sea level thrust of 842 kN (nominal) with burn time of 5.98 second (nominal). The nozzle end of LEM is mounted at the fore end of the launch vehicle to avoid exhaust plume impingement on crew module. This is why there are reverse flow multiple nozzle in

30807-654: The test, about 700 parameters were monitored and the performance of all the systems were normal. The second-largest functioning solid propellant booster in the world is 20 meters in length and 3.2 meters in diameter. Like all systems for Gaganyaan mission, the HS200 booster was designed with a number of enhancements intended to increase the safety and dependability of different systems. The enhancements include stronger ignition and insulation systems, improved digital control electronics as well as extra safety features for motor case joints. This booster's control system makes use of one of

30996-411: The three comprehensive tests in order to thoroughly assess the functionality and dependability of the drogue parachutes. The first test, which replicated the maximum reefed weight, introduced reefing in a mortar-deployed parachute for the first time in India. The second test replicated the maximum disreefed load, while the third test demonstrated the drogue parachute's deployment in a scenario that mirrored

31185-653: The turn of the 1st-millennium CE, it has been written in various Brahmic scripts , and in the modern era most commonly in Devanagari . Sanskrit's status, function, and place in India's cultural heritage are recognized by its inclusion in the Constitution of India 's Eighth Schedule languages . However, despite attempts at revival, there are no first-language speakers of Sanskrit in India. In each of India's recent decennial censuses, several thousand citizens have reported Sanskrit to be their mother tongue, but

31374-494: The use of French medical tools, equipment, and consumables by Indian astronauts. The Indian space crew will thus have access to French technology created by CNES that has been tested and is now in use aboard the International Space Station . CNES will also provide radiation- and shock-resistant carry bags to India to protect equipment. The future cooperation include parabolic flights conducted by Novespace for instrument testing and astronaut training, as well as technical assistance for

31563-408: The variants in the usage of Sanskrit in different regions of India. The ten Vedic scholars he quotes are Āpiśali, Kaśyapa , Gārgya, Gālava, Cakravarmaṇa, Bhāradvāja , Śākaṭāyana, Śākalya, Senaka and Sphoṭāyana. In the Aṣṭādhyāyī , language is observed in a manner that has no parallel among Greek or Latin grammarians. Pāṇini's grammar, according to Renou and Filliozat, is a classic that defines

31752-564: The vernacular Prakrits. Many Sanskrit dramas indicate that the language coexisted with the vernacular Prakrits. The cities of Varanasi , Paithan , Pune and Kanchipuram were centers of classical Sanskrit learning and public debates until the arrival of the colonial era. According to Lamotte , Sanskrit became the dominant literary and inscriptional language because of its precision in communication. It was, states Lamotte, an ideal instrument for presenting ideas, and as knowledge in Sanskrit multiplied, so did its spread and influence. Sanskrit

31941-420: The vicinity of Jupiter are too hostile for human survival. Outer planets such as Saturn , Uranus , and Neptune are too distant to reach with current crewed spaceflight technology, so telerobotic probes are the only way to explore them. Telerobotics also allows exploration of regions that are vulnerable to contamination by Earth micro-organisms since spacecraft can be sterilized. Humans can not be sterilized in

32130-502: The Ṛg-veda is distinctly more archaic than other Vedic texts, and in many respects, the Rigvedic language is notably more similar to those found in the archaic texts of Old Avestan Zoroastrian Gathas and Homer's Iliad and Odyssey . According to Stephanie W. Jamison and Joel P. Brereton – Indologists known for their translation of the Ṛg-veda – the Vedic Sanskrit literature "clearly inherited" from Indo-Iranian and Indo-European times

32319-503: Was Vostok 1 , which carried Soviet cosmonaut Yuri Gagarin into space in 1961, and completed a full Earth orbit. There were five other crewed missions which used a Vostok spacecraft . The second crewed spacecraft was named Freedom 7 , and it performed a sub-orbital spaceflight in 1961 carrying American astronaut Alan Shepard to an altitude of just over 187 kilometers (116 mi). There were five other crewed missions using Mercury spacecraft . Other Soviet crewed spacecraft include

32508-612: Was a spaceplane that was launched at NASA’s Kennedy Space Centre and landed mainly at the Shuttle Landing Facility , which is part of Kennedy Space Centre. A second launch site, Vandenberg Space Launch Complex 6 in California , was revamped so it could be used to launch the shuttles, but it was never used. The launch system could lift about 29 tonnes (64,000 lb) into an eastward Low Earth Orbit . Each orbiter weighed roughly 78 tonnes (172,000 lb), however

32697-408: Was a spoken language ( bhasha ) used by the cultured and educated. Some sutras expound upon the variant forms of spoken Sanskrit versus written Sanskrit. Chinese Buddhist pilgrim Xuanzang mentioned in his memoir that official philosophical debates in India were held in Sanskrit, not in the vernacular language of that region. According to Sanskrit linguist professor Madhav Deshpande, Sanskrit

32886-427: Was a spoken language in a colloquial form by the mid-1st millennium BCE which coexisted with a more formal, grammatically correct form of literary Sanskrit. This, states Deshpande, is true for modern languages where colloquial incorrect approximations and dialects of a language are spoken and understood, along with more "refined, sophisticated and grammatically accurate" forms of the same language being found in

33075-521: Was accepted and formally announced by Prime Minister Narendra Modi during his 2018 Independence Day address to the nation. The Gaganyaan Programme, was approved by the Union Cabinet on 28 December 2018. The current design calls for a crew of three. ISRO will perform four biological and two physical science experiments related to microgravity during the Gaganyaan mission. ISRO is planning to replace hydrazine with green propellant on Gaganyaan missions, for which Liquid Propulsion Systems Centre (LPSC)

33264-472: Was adopted voluntarily as a vehicle of high culture, arts, and profound ideas. Pollock disagrees with Lamotte, but concurs that Sanskrit's influence grew into what he terms a "Sanskrit Cosmopolis" over a region that included all of South Asia and much of southeast Asia. The Sanskrit language cosmopolis thrived beyond India between 300 and 1300 CE. Today, it is believed that Kashmiri is the closest language to Sanskrit. Reinöhl mentions that not only have

33453-738: Was also the language of some of the oldest surviving, authoritative and much followed philosophical works of Jainism such as the Tattvartha Sutra by Umaswati . The Sanskrit language has been one of the major means for the transmission of knowledge and ideas in Asian history. Indian texts in Sanskrit were already in China by 402 CE, carried by the influential Buddhist pilgrim Faxian who translated them into Chinese by 418 CE. Xuanzang , another Chinese Buddhist pilgrim, learnt Sanskrit in India and carried 657 Sanskrit texts to China in

33642-457: Was due to expensive refurbishment costs and the external tank being expended. Once a landing had occurred, the SRBs and many parts of the orbiter had to be disassembled for inspection, which was long and arduous. Furthermore, the RS-25 engines had to be replaced every few flights. Each of the heat shielding tiles had to go in one specific area on the orbiter, increasing complexity more. Adding to this,

33831-405: Was forced to urge national laboratories and domestic industry to begin developing the technology because there were no foreign partners available to share the technology. The first orbiter module adaptor assembly (OMA) for Gaganyaan was provided by Kineco Kaman Composites on 23 December 2023. The OMA is a conical structure with a diameter of 4 meters, composed of carbon-fiber-reinforced polymers . It

34020-465: Was free for a docking mechanism, but primary entry was evidently through a side hatch secured by explosive bolts. Glavkosmos and Human Space Flight Centre signed a deal in October 2019 for Energia to equip the Gaganyaan crew with life support system and supply thermal control system for the spacecraft. In addition to supplying food, water, and oxygen and assisting in regulating body temperature,

34209-687: Was launched during the International Geophysical Year from Site No.1/5 , at the 5th Tyuratam range, in Kazakh SSR (now at the Baikonur Cosmodrome ). The satellite travelled at 29,000 kilometres per hour (18,000 mph), taking 96.2 minutes to complete an orbit, and emitted radio signals at 20.005 and 40.002  MHz While Sputnik 1 was the first spacecraft to orbit the Earth, other human-made objects had previously reached an altitude of 100 km, which

34398-526: Was manually operated, though an autonomous landing system was added while the shuttle was still on service. It had an in orbit maneouvreing system known as the Orbital Manoeuvring System, which used the hypergolic propellants monomethylhydrazine (MMH) and dinitrogen tetroxide , which was used for orbital insertion, changes to orbits and the deorbit burn. Though the shuttle’s goals were to drastically decrease launch costs, it did not do so, ending up being much more expensive than similar expendable launchers. This

34587-439: Was planned to begin reusable private spaceflight carrying paying passengers in 2014, but was delayed after the crash of VSS Enterprise . The Space Shuttle is a retired reusable Low Earth Orbital launch system. It consisted of two reusable Solid Rocket Boosters that landed by parachute, were recovered at sea, and were the most powerful rocket motors ever made until they were superseded by those of NASA’s SLS rocket, with

34776-472: Was sanctioned in February 2009, But it fell short due to limited developmental funding. Initially, the first uncrewed flight of the orbital vehicle was proposed to be in 2013, then it was revised to 2016. However, in April 2012, it was reported that funding problems placed the future of the project in serious doubt. And in August 2013, it was announced that all crewed spaceflight efforts by India had been designated as being "off ISRO's priority list". By early 2014,

34965-403: Was taking a longer route that allowed it to visit Uranus and Neptune, whereas Voyager 1 did not visit Uranus or Neptune, instead choosing to fly past Saturn’s satellite Titan . As of August 2023, Voyager 1 has passed 160 astronomical units , which means it is over 160 times farther from the Sun than Earth is. This makes it the farthest spacecraft from the Sun. Voyager 2 is 134 AU away from

35154-413: Was the Buran -class shuttle , launched by the USSR on November 15, 1988, although it made only one flight and this was uncrewed. This spaceplane was designed for a crew and strongly resembled the U.S. Space Shuttle, although its drop-off boosters used liquid propellants and its main engines were located at the base of what would be the external tank in the American Shuttle. Lack of funding, complicated by

35343-400: Was the Space Shuttle orbiter . The first orbiter to fly in space, the Space Shuttle Columbia , was launched by the USA on the 20th anniversary of Yuri Gagarin 's flight, on April 12, 1981. During the Shuttle era, six orbiters were built, all of which have flown in the atmosphere and five of which have flown in space. Enterprise was used only for approach and landing tests, launching from

35532-415: Was to design a simple capsule with an endurance of about a week in space, a capacity of two astronauts, and a splashdown landing after re-entry. The project was commissioned in 2007, with expected completion by 2024 and a budget of around ₹10,000 crore. The design was finalized by March 2008 and submitted to the Government of India for funding. The government's funding for the Indian Human Spaceflight Program

35721-442: Was visualized as "pervading all creation", another representation of the world itself; the "mysterious magnum" of Hindu thought. The search for perfection in thought and the goal of liberation were among the dimensions of sacred sound, and the common thread that wove all ideas and inspirations together became the quest for what the ancient Indians believed to be a perfect language, the "phonocentric episteme" of Sanskrit. Sanskrit as
