65-605: Firefly Aerospace Blue Ghost , or simply Blue Ghost , is a class of lunar landers designed and manufactured by Firefly Aerospace (Firefly). Firefly plans to operate Blue Ghost landers to deliver small payloads to the surface of the Moon . The first Blue Ghost mission is scheduled for launch in January 2025. Firefly is the prime contractor for lunar delivery services using Blue Ghost landers. Firefly provides or sub-contracts Blue Ghost payload integration, launch from Earth, landing on
130-468: A partial success occurs when a spacecraft lands intact on the Moon but its in-situ operations is compromised as a result of the landing process for any reason. Landing on any Solar System body comes with challenges unique to that body. The Moon has relatively high gravity compared to that of asteroids or comets—and some other planetary satellites —and no significant atmosphere. Practically, this means that
195-548: A brief hop off the lunar surface. The Apollo Lunar Module was the lunar lander for the United States' Apollo program . As of 2024, it is the only crewed lunar lander. The Apollo program completed six successful lunar soft-landings from 1969 until 1972; a seventh lunar landing attempt by the Apollo program was aborted when Apollo 13 's service module suffered explosive venting from its oxygen tanks. The LK lunar module
260-586: A follow-up robotic lander named Beresheet 2 . India's Chandrayaan Programme conducted an unsuccessful robotic lunar soft-landing attempt on 6 September 2019 as part of its Chandrayaan-2 spacecraft with the lander crashing on the Moon's surface. On 23 August 2023, the program's follow-up Chandrayaan-3 lander achieved India's first robotic soft-landing and later conducted a brief hop on 3 September 2023 to test technologies required for Indian lunar sample return mission called Chandrayaan-4 . Japan's ispace (not to be confused with China's i-Space ) attempted

Space station systems include technology that enables humans to live in outer space for a prolonged period of time. Such technology includes filtration systems for human waste disposal and air production. Skylab used 72% oxygen and 28% nitrogen at
390-411: A long beam extending another cabin section or counterweight, spinning it at an appropriate speed will cause centrifugal force to simulate the effect of gravity. If ω is the angular velocity of the ship's spin, then the acceleration at a radius r is: Notice the magnitude of this effect varies with the radius of rotation, which crewmembers might find inconvenient depending on the cabin design. Also,
455-516: A lunar soft-landing by its Hakuto-R Mission 1 robotic lander on 25 April 2023. The attempt was unsuccessful and the lander crashed into the lunar surface. The company has plans for another landing attempt in 2024. Russia's Luna-Glob program, the successor program to the Soviet Union's Luna program , launched the Luna 25 lunar lander on 10 August 2023; the probe's intended destination was near
520-573: A maximum of 650 W of power. ASI by Rocket Lab provides flight, ground and GN&C software, trajectory design, orbit determination, and software testbed integration. Firefly asserts that in house end to end manufacturing and testing of the Blue Ghost structure is a differentiator among the CLPS landers. NASA awarded Firefly the first Blue Ghost lunar delivery task order in February, 2021 as part of
585-401: A much stricter range of between −40 and 50 °C (−40 and 122 °F), and human comfort requires a range of 20 to 24 °C (68 to 75 °F). This means that the lander must cool and heat its instruments or crew compartment. The length of the lunar night makes it difficult to use solar electric power to heat the instruments, and nuclear heaters are often used. Achieving a soft landing
650-424: A similar method. Airbag methods are not typical. For example, NASA's Surveyor 1 probe, launched around the same time as Luna 9, did not use an airbag for final touchdown. Instead, after it arrested its velocity at an altitude of 3.4m it simply fell to the lunar surface. To accommodate the fall the spacecraft was equipped with crushable components that would soften the blow and keep the payload safe. More recently,
715-553: A space mission, and outputs a similar amount in the form of waste solids, waste liquids, and carbon dioxide . The mass breakdown of these metabolic parameters is as follows: 0.84 kg (1.9 lb) of oxygen, 0.62 kg (1.4 lb) of food, and 3.54 kg (7.8 lb) of water consumed, converted through the body's physiological processes to 0.11 kg (3.9 oz) of solid wastes, 3.89 kg (8.6 lb) of liquid wastes, and 1.00 kg (2.20 lb) of carbon dioxide produced. These levels can vary due to activity level of

#1732798498812780-575: A specific mission assignment, but must obey the principle of mass balance . Actual water use during space missions is typically double the given value, mainly due to non-biological use (e.g. showering). Additionally, the volume and variety of waste products varies with mission duration to include hair, finger nails, skin flaking, and other biological wastes in missions exceeding one week in length. Other environmental considerations such as radiation, gravity, noise, vibration, and lighting also factor into human physiological response in outer space, though not with
845-411: A surface saturation accommodation facility provides breathing gas and other services to support life for the personnel under pressure. It includes the following components: Underwater habitats differ in that the ambient external pressure is the same as internal pressure, so some engineering problems are simplified. Underwater habitats balance internal pressure with the ambient external pressure, allowing
910-673: A total pressure of 5 psi. The Salyut and Mir space stations contained an air-like Oxygen and Nitrogen mixture at approximately sea-level pressures of 93.1 kPa (13.5psi) to 129 kPa (18.8 psi) with an Oxygen content of 21% to 40%. The life-support system for the Bigelow Commercial Space Station is being designed by Bigelow Aerospace in Las Vegas, Nevada . The space station will be constructed of habitable Sundancer and BA 330 expandable spacecraft modules. As of October 2010, " human-in-the-loop testing of

CyBLiSS ("Cyanobacterium-Based Life Support Systems") is a concept developed by researchers from several space agencies ( NASA ,
1040-564: Is a spacecraft designed to land on the surface of the Moon . As of 2024, the Apollo Lunar Module is the only lunar lander to have ever been used in human spaceflight, completing six lunar landings from 1969 to 1972 during the United States' Apollo Program . Several robotic landers have reached the surface, and some have returned samples to Earth. The design requirements for these landers depend on factors imposed by
1105-411: Is consumed by crew members for drinking, cleaning activities, EVA thermal control, and emergency uses. It must be stored, used, and reclaimed (from waste water and exhaled water vapor) efficiently since no on-site sources currently exist for the environments reached in the course of human space exploration. Future lunar missions may utilize water sourced from polar ices; Mars missions may utilize water from
1170-399: Is done, for example, by composting toilets which reintegrate waste material (excrement) back into the system, allowing the nutrients to be taken up by the food crops. The food coming from the crops is then consumed again by the system's users and the cycle continues. The logistics and area requirements involved however have been prohibitive in implementing such a system to date. Depending on
1235-505: Is generally applied to systems supporting human life in situations where the outside environment is hostile, such as outer space or underwater , or medical situations where the health of the person is compromised to the extent that the risk of death would be high without the function of the equipment. In human spaceflight , a life-support system is a group of devices that allow a human being to survive in outer space. US government space agency NASA , and private spaceflight companies use
1300-482: Is in contrast to a small asteroid, in which "landing" is more often called "docking" and is a matter of rendezvous and matching velocity more than slowing a rapid descent. Since rocketry is used for descent and landing, the Moon's gravity necessitates the use of more fuel than is needed for asteroid landing. Indeed, one of the central design constraints for the Apollo program's Moon landing was mass (as more mass requires more fuel to land) required to land and take off from
1365-428: Is the overarching goal of any lunar lander, and distinguishes landers from impactors, which were the first type of spacecraft to reach the surface of the Moon. All lunar landers require rocket engines for descent. Orbital speed around the Moon can, depending on altitude, exceed 1500 m/s. Spacecraft on impact trajectories can have speeds well in excess of that. In the vacuum the only way to decelerate from that speed
SECTION 20
#17327984988121430-401: Is to use a rocket engine. The stages of landing can include: Lunar landings typically end with the engine shutting down when the lander is several feet above the lunar surface. The idea is that engine exhaust and lunar regolith can cause problems if they were to be kicked back from the surface to the spacecraft, and thus the engines cut off just before touchdown. Engineers must ensure that
1495-524: The Artemis program . The mission is planned to land at Mare Crisium , a 500 km (310 mi) wide basin visible from Earth. Instruments will gather data to provide insight into the Moon's regolith – loose, fragmented rock and soil – properties, geophysical characteristics, and the interaction of solar wind and Earth's magnetic field , helping to prepare for human missions to the lunar surface. On May 20, 2021, Firefly selected SpaceX 's Falcon 9 as
1560-506: The Commercial Lunar Payload Services (CLPS) initiative. On February 4, 2021, NASA awarded Firefly a contract worth US$ 93.3 million to deliver a suite of ten science investigations and technology demonstrations to the Moon in 2023. The award is part of the CLPS initiative, in which NASA is securing the service of commercial partners to quickly land science and technology payloads on the lunar surface as part of

The goal is to make future human-occupied outposts on Mars as independent of Earth as possible (explorers living "off the land"), to reduce mission costs and increase safety. Even though developed independently, CyBLiSS would be complementary to other BLSS projects (such as MELiSSA) as it can connect them to materials found on Mars, thereby making them sustainable and expandable there. Instead of relying on
1690-549: The Lunokhod robotic lunar rover in 1970 and 1973. Luna achieved a total of seven successful soft-landings out of 27 landing attempts. The United States' Surveyor program first soft-landed Surveyor 1 on June 2, 1966, this initial success was followed by four additional successful soft-landings, the last occurring on January 10, 1968. The Surveyor program achieved a total of five successful soft landings out of seven landing attempts through January 10, 1968. Surveyor 6 even did
1755-592: The Soyuz spacecraft is called the Kompleks Sredstv Obespecheniya Zhiznideyatelnosti (KSOZh) ( Russian : Комплекс Средств Обеспечения Жизнедеятельности (KCOЖ) ). Vostok, Voshkod and Soyuz contained air-like mixtures at approximately 101kPa (14.7 psi). The life support system provides a nitrogen/oxygen atmosphere at sea level partial pressures. The atmosphere is then regenerated through KO2 cylinders, which absorb most of
1820-624: The United States , the Soviet Union cancelled both the N1 Rocket and the LK Lunar Module programs without any further development. The Chinese Lunar Exploration Program (also known as the Chang'e project) includes robotic lander, rover, and sample-return components; the program realized an initial successful lunar soft-landing with the Chang'e 3 spacecraft on 14 December 2013. As of 2023,

Medical life-support systems include heart-lung machines , medical ventilators and dialysis equipment. A crewmember of typical size requires approximately 5 kilograms (11 lb) of food , water , and oxygen per day to perform standard activities on
1950-404: The payload , flight rate, propulsive requirements, and configuration constraints. Other important design factors include overall energy requirements, mission duration, the type of mission operations on the lunar surface, and life support system if crewed. The relatively high gravity (higher than all known asteroids, but lower than all Solar System planets) and lack of lunar atmosphere negates
2015-614: The 5th country to soft land on the moon. In January 2024, the first mission of the NASA-funded CLPS program, Peregrine Mission One , suffered a fuel leak several hours after launch, resulting in losing the ability to maintain attitude control and charge its battery, thereby preventing it from reaching lunar orbit and precluding a landing attempt. The probe subsequently burnt up in Earth's atmosphere. The second CLPS probe Odysseus landed successfully on 22 February 2024 on

The CCT-ARS provides seven primary spacecraft life support functions in
2275-582: The Chinese Chang'e 3 lander used a similar technique, falling 4m after its engine shut down. Perhaps the most famous lunar landers, those of the Apollo Program , were robust enough to handle the drop once their contact probes detected that landing was imminent. The landing gear was designed to withstand landings with engine cut-out at up to 10 feet (3.0 m) of height, though it was intended for descent engine shutdown to commence when one of

This mission is the first private -NASA partnership to land on the Moon and the first landing using cryogenic propellants . However, the mission experienced some anomalies, including tipping-over on one side on the lunar surface; an off-nominal initial lunar orbit, a non-functioning landing LIDAR instrument, and apparently low communication bandwidth . Later it
2470-399: The Moon. The lunar thermal environment is influenced by the length of the lunar day. Temperatures can swing between approximately −250 to 120 °C (−418.0 to 248.0 °F) (lunar night to lunar day). These extremes occur for fourteen Earth days each, so thermal control systems must be designed to handle long periods of extreme cold or heat. Most spacecraft instruments must be kept within

These systems are also known as closed ecological systems . They have the advantage of using solar energy as primary energy only and being independent from logistical support with fuel. Natural systems have
2990-486: The highest degree of efficiency due to integration of multiple functions. They also provide the proper ambience for humans which is necessary for a longer stay in outer space. Underwater habitats and surface saturation accommodation facilities provide life-support for their occupants over periods of days to weeks. The occupants are constrained from immediate return to surface atmospheric pressure by decompression obligations of up to several weeks. The life support system of
3055-579: The intention of returning NASA astronauts to the Moon. In 2018, NASA solicited bids from nine companies, including Firefly Aerospace, for the Commercial Lunar Payload Services (CLPS) program. CLPS is part of the NASA Artemis program ; one of the long-term goals of Artemis is establishing a permanent crewed base on the Moon . In 2021, Firefly Aerospace received a NASA contract that was valued at US$ 93 million to conduct lunar landings for NASA. Lunar lander A lunar lander or Moon lander

Two methods of generating artificial weight in outer space exist. If a spacecraft's engines could produce thrust continuously on the outbound trip with a thrust level equal to the mass of the ship, it would continuously accelerate at
3250-481: The life-support system are life-critical , and are designed and constructed using safety engineering techniques. In underwater diving , the breathing apparatus is considered to be life support equipment, and a saturation diving system is considered a life-support system – the personnel who are responsible for operating it are called life support technicians . The concept can also be extended to submarines , crewed submersibles and atmospheric diving suits , where

China launched Chang'e 6 from China's Hainan Island on 3 May 2024; this mission seeks to conduct the first lunar sample return from the far side of the Moon . This is China's second lunar sample return mission, the first was successfully completed by Chang'e 5 when it returned 1.731 kg of lunar near side material to the Earth on 16 December 2020. The Chang'e 6 lander successfully landed in
3445-413: The more immediate effect that the metabolic parameters have. Outer space life-support systems maintain atmospheres composed, at a minimum, of oxygen, water vapor and carbon dioxide. The partial pressure of each component gas adds to the overall barometric pressure . However, the elimination of diluent gases substantially increases fire risks, especially in ground operations when for structural reasons

Primary gas supply, power and communications to
3575-594: The only method of descent and landing that can provide sufficient thrust with current technology is based on chemical rockets . In addition, the Moon has a long solar day . Landers will be in direct sunlight for more than two weeks at a time, and then in complete darkness for another two weeks. This causes significant problems for thermal control. As of 2019, space probes have landed on all three bodies other than Earth that have solid surfaces and atmospheres thick enough to make aerobraking possible: Mars , Venus , and Saturn's moon Titan . These probes were able to leverage
3640-419: The phrase "environmental control and life-support system" or the acronym ECLSS when describing these systems. The life-support system may supply air, water and food. It must also maintain the correct body temperature, an acceptable pressure on the body and deal with the body's waste products. Shielding against harmful external influences such as radiation and micro-meteorites may also be necessary. Components of

The term landing attempt as used here includes any mission that was launched with the intent to land on the Moon, including all missions which failed to reach lunar orbit for any reason. A landing attempt by a spacecraft is classified as full success if it lands intact on the Moon and is situated in its designed orientation/attitude and fully functional, while
3835-433: The total cabin pressure must exceed the external atmospheric pressure; see Apollo 1 . Furthermore, oxygen toxicity becomes a factor at high oxygen concentrations. For this reason, most modern crewed spacecraft use conventional air (nitrogen/oxygen) atmospheres and use pure oxygen only in pressure suits during extravehicular activity where acceptable suit flexibility mandates the lowest inflation pressure possible.
