45-546: On January 14, 2017, the SS-520-4 rocket (modified sounding rocket) attempted to become the lightest and smallest launch vehicle to send a payload to orbit, however, the rocket failed to reach orbit. A second attempt was made on February 3, 2018. This time, the rocket reached orbit and successfully deployed TRICOM-1R (Tasuki), a 3U CubeSat . Its 2018 launch made it the smallest orbital rocket both in mass and height. A retired single stage Japanese sounding rocket . The S-160 had

90-435: A formation . The generic term "small satellite" or "smallsat" is also sometimes used, as is "satlet". Examples: Astrid-1 and Astrid-2, as well as the set of satellites currently announced for LauncherOne (below) In 2018, the two Mars Cube One microsats—massing just 13.5 kg (30 lb) each—became the first CubeSats to leave Earth orbit for use in interplanetary space. They flew on their way to Mars alongside

135-464: A 10 kg (22 lb) payload into a 250 km (160 mi) orbit to an even-more-capable clustered "20/450 Nano/Micro Satellite Launch Vehicle" (NMSLV) capable of delivering 20 kg (44 lb) payloads into 450 km (280 mi) circular orbits . The Boeing Small Launch Vehicle is an air-launched three-stage-to-orbit launch vehicle concept aimed to launch small payloads of 45 kg (100 lb) into low Earth orbit. The program

180-435: A larger "mother" satellite for communication with ground controllers or for launching and docking with picosatellites. Picosatellites are emerging as a new alternative for do-it-yourself kitbuilders. Picosatellites are currently commercially available across the full range of 0.1–1 kg (0.22–2.2 lb). Launch opportunities are now available for $ 12,000 to $ 18,000 for sub-1 kg picosat payloads that are approximately

225-425: A market value estimated at US$ 7.4 billion . By mid-2015, many more launch options had become available for smallsats, and rides as secondary payloads had become both greater in quantity and easier to schedule on shorter notice. In a surprising turn of events, the U.S. Department of Defense , which had for decades procured heavy satellites on decade-long procurement cycles, is making a transition to smallsats in

270-433: A mass of no more than 1.33 kilograms (2.9 lb) per unit. The CubeSat concept was first developed in 1999 by a collaborative team of California Polytechnic State University and Stanford University , and the specifications, for use by anyone planning to launch a CubeSat-style nanosatellite, are maintained by this group. With continued advances in the miniaturization and capability increase of electronic technology and

315-508: A maximum altitude of approximately 190 km (120 mi). TRICOM-1 is believed to have crashed into the Pacific Ocean with its launcher. Despite loss of telemetry from the rocket, the satellite was automatically released from the rocket around the time it was scheduled to, and ground stations were able to briefly receive telemetry from the satellite. Nanosatellite A small satellite , miniaturized satellite , or smallsat

360-600: A maximum flight altitude of 80 kilometers, a launch mass of 100 kg, a diameter of 160 mm and a length of 4 meters. It was launched 13 times between 1965 and 1972. A retired single-stage sounding rocket developed by the Institute of Space and Aeronautical Science of the University of Tokyo, predecessor of the Institute of Space and Astronautical Science (ISAS), to study the ionosphere. A variant S-210JA

405-474: A number of companies began development of launch vehicles specifically targeted at the smallsat market. In particular, with larger numbers of smallsats flying, the secondary payload paradigm does not provide the specificity required for many small satellites that have unique orbital and launch-timing requirements. Some USA-based private companies that at some point in time have launched smallsat launch vehicles commercially: The term "microsatellite" or "microsat"

450-544: Is a satellite of low mass and size, usually under 1,200 kg (2,600 lb). While all such satellites can be referred to as "small", different classifications are used to categorize them based on mass . Satellites can be built small to reduce the large economic cost of launch vehicles and the costs associated with construction. Miniature satellites, especially in large numbers, may be more useful than fewer, larger ones for some purposes – for example, gathering of scientific data and radio relay . Technical challenges in

495-472: Is a technology demonstration with no serial production planned. It was launched January 14, 2017, but failed to reach orbit due to a loss of telemetry. If successful, it would have become the smallest and lightest vehicle to ever put an object in orbit; surpassing the Japanese Lambda-4S . Telemetry was lost 20 seconds into flight. 3 minutes into the flight, controllers sent an abort code commanding

540-585: Is a two-stage sounding rocket or three-stage orbital rocket , which uses S-520 as the first stage. Unlike the previous S-Series rockets, the SS-520 is intended to demonstrate how small an orbital launch vehicle can be. When used as a suborbital sounding rocket, it can launch a 140 kilograms (310 lb) payload to an altitude between 800 and 1000 km. The first two SS-520s were launched in 1998 and 2000 respectively and successfully carried their payloads on sub-orbital missions. After further development and

585-681: Is designed to form a quantum communication network as well as communicate with Earth through an optical ground station. The term "small satellite", or sometimes "minisatellite", often refers to an artificial satellite with a wet mass (including fuel) between 100 and 500 kg (220 and 1,100 lb), but in other usage has come to mean any satellite under 500 kg (1,100 lb). Small satellite examples include Demeter , Essaim , Parasol , Picard , MICROSCOPE , TARANIS , ELISA , SSOT , SMART-1 , Spirale-A and -B , and Starlink satellites. Although smallsats have traditionally been launched as secondary payloads on larger launch vehicles,

630-517: Is proposed to drive down launch costs for U.S. military small satellites to as low as US$ 300,000 per launch ($ 7,000/kg) and, if the development program was funded, as of 2012 could be operational by 2020. The Swiss company Swiss Space Systems (S3) has announced plans in 2013 to develop a suborbital spaceplane named SOAR that would launch a microsat launch vehicle capable of putting a payload of up to 250 kg (550 lb) into low Earth orbit. The Spanish company PLD Space born in 2011 with

675-695: Is the opportunity to enable missions that a larger satellite could not accomplish, such as: The nanosatellite and microsatellite segments of the satellite launch industry have been growing rapidly in the 2010s. Development activity in the 1–50 kg (2.2–110.2 lb) range has been significantly exceeding that in the 50–100 kg (110–220 lb) range. In the 1–50 kg range alone, fewer than 15 satellites were launched annually in 2000 to 2005, 34 in 2006, then fewer than 30 launches annually during 2007 to 2011. This rose to 34 launched in 2012 and 92 launched in 2013. European analyst Euroconsult projects more than 500 smallsats being launched in 2015–2019 with

720-422: Is usually applied to the name of an artificial satellite with a wet mass between 10 and 100 kg (22 and 220 lb). However, this is not an official convention and sometimes those terms can refer to satellites larger than that, or smaller than that (e.g., 1–50 kg (2.2–110.2 lb)). Sometimes, designs or proposed designs from some satellites of these types have microsatellites working together or in

765-486: The PicoSAT series of microsatellites) is usually applied to artificial satellites with a wet mass between 0.1 and 1 kg (0.22 and 2.2 lb), although it is sometimes used to refer to any satellite that is under 1 kg in launch mass. Again, designs and proposed designs of these types usually have multiple picosatellites working together or in formation (sometimes the term "swarm" is applied). Some designs require

810-606: The 2020s. The office of space acquisition and integration said in January 2023 that "the era of massive satellites needs to be in the rear view mirror for the Department of Defense" with small satellites being procured for DoD needs in all orbital regimes, regardless of "whether it's LEO MEO or GEO " while aiming for procurements in under three years. The smaller satellites are deemed to be harder for an enemy to target, as well as providing more resilience through redundancy in

855-528: The DARPA SeeMe program that intended to release a " constellation of 24 micro-satellites (~20 kg (44 lb) range) each with 1-m imaging resolution ." The program was cancelled in December 2015. In April 2013, Garvey Spacecraft was awarded a US$ 200,000 contract to evolve their Prospector 18 suborbital launch vehicle technology into an orbital nanosat launch vehicle capable of delivering

900-457: The ISS external platform Materials International Space Station Experiment (MISSE-8) for testing. In April 2014, the nanosatellite KickSat was launched aboard a Falcon 9 rocket with the intention of releasing 104 femtosatellite-sized chipsats, or "Sprites". In the event, they were unable to complete the deployment on time due to a failure of an onboard clock and the deployment mechanism reentered

945-584: The S-310 has completed 57 sub-orbital launches, with its most recent launch occurring on January 9, 2020. The S-520 was developed to replace the K-9M and K-10 type sounding rockets. It is an active single-stage sounding rocket capable of launching a 100 kg payload above 300 km and provided more than five minutes of micro-gravity flight for experiments. The first launch took place in 1980, and most recently flew on 11 November 2024 (UTC). This version

990-478: The addition of a third stage, the fourth and fifth instances of the SS-520 were launched on full orbital trajectories. This is the fourth vehicle configuration of the SS-520. It includes a small third stage, and is engineered to place the payload into an orbital speed of more than 27,000 km/h (17,000 mph), to put a 4 kg (8.8 lb) 3U CubeSat into a 180 km × 1,500 km (110 mi × 930 mi) orbit with an inclination of 31°. It

1035-927: The atmosphere and burned up. Small satellites usually require innovative propulsion, attitude control , communication and computation systems. Larger satellites usually use monopropellants or bipropellant combustion systems for propulsion and attitude control; these systems are complex and require a minimal amount of volume to surface area to dissipate heat. These systems may be used on larger small satellites, while other micro/nanosats have to use electric propulsion, compressed gas, vaporizable liquids such as butane or carbon dioxide or other innovative propulsion systems that are simple, cheap and scalable. Small satellites can use conventional radio systems in UHF, VHF, S-band and X-band, although often miniaturized using more up-to-date technology as compared to larger satellites. Tiny satellites such as nanosats and small microsats may lack

1080-608: The atmosphere on 14 May 2014, without having deployed any of the 5-gram femtosats. ThumbSat is another project intending to launch femtosatellites in the late 2010s. ThumbSat announced a launch agreement with CubeCat in 2017 to launch up to 1000 of the very small satellites. In March 2019, the CubeSat KickSat-2 deployed 105 femtosats called "ChipSats" into Earth orbit. Each of the ChipSats weighed 4 grams. The satellites were tested for 3 days, and they then reentered

1125-649: The construction of small satellites may include the lack of sufficient power storage or of room for a propulsion system . One rationale for miniaturizing satellites is to reduce the cost; heavier satellites require larger rockets with greater thrust that also have greater cost to finance. In contrast, smaller and lighter satellites require smaller and cheaper launch vehicles and can sometimes be launched in multiples. They can also be launched 'piggyback', using excess capacity on larger launch vehicles. Miniaturized satellites allow for cheaper designs and ease of mass production. Another major reason for developing small satellites

1170-592: The data when the satellite flies above ground stations. TRICOM-1R also conducted Earth observation using its main camera and five sub cameras. The name of the spacecraft was partially based on the Japanese word Torikomu ( 取り込む ) , which means 'to take in', due to the store and forward nature of the mission. TRICOM-1R was successfully placed into orbit on 3 February 2018 at 05:03 UTC (14:03 JST), of 187 km × 2,012 km (116 mi × 1,250 mi) altitude with orbital inclination angle of 31°. TRICOM-1R

Virgin Orbit has been working on the LauncherOne concept since late 2008, and as of 2015 , is making it a larger part of Virgin's core business plan as the Virgin human spaceflight program has experienced multiple delays and a fatal accident in 2014. In December 2012, DARPA announced that the Airborne Launch Assist Space Access program would provide the microsatellite rocket booster for

1260-670: The design of a large distributed network of satellite assets . In 2021, the first autonomous nanosatellites , part of the Adelis-SAMSON mission, designed and developed by the Technion and Rafael in Israel were launched into space. In 2023, SpaceX launched a 20cm quantum communication nano satellite developed by the Tel Aviv University , it is the world's first quantum communication satellite. TAU's nanosatellite

1305-428: The emergence of the technological advances of miniaturization and increased capital to support private spaceflight initiatives in the 2010s, several startups have been formed to pursue opportunities with developing a variety of small-payload Nanosatellite Launch Vehicle (NLV) technologies. NLVs proposed or under development include: Actual NS launches: The term "picosatellite" or "picosat" (not to be confused with

1350-482: The objective of developing low cost launch vehicles called Miura 1 and Miura 5 with the capacity to place up to 150 kg (330 lb) into orbit. The term "nanosatellite" or "nanosat" is applied to an artificial satellite with a wet mass between 1 and 10 kg (2.2 and 22.0 lb). Designs and proposed designs of these types may be launched individually, or they may have multiple nanosatellites working together or in formation, in which case, sometimes

1395-514: The power supply or mass for large conventional radio transponders , and various miniaturized or innovative communications systems have been proposed, such as laser receivers, antenna arrays and satellite-to-satellite communication networks. Few of these have been demonstrated in practice. Electronics need to be rigorously tested and modified to be "space hardened" or resistant to the outer space environment (vacuum, microgravity, thermal extremes, and radiation exposure). Miniaturized satellites allow for

1440-527: The rocket was cleared for intensive use at the Japanese Antarctic base at Syowa in 1972–1978. The S-210, like other rockets in the series, used a solid rocket motor. The propellant grain of the motor included Hydroxyl-terminated polybutadiene (HTPB) binder, making it better suited for the cold temperatures of the Antarctic launch site. It was built to replace the smaller S-160 rocket which

1485-934: The same mission cost, with significantly increased revisit times: every area of the globe can be imaged every 3.5 hours rather than the once per 24 hours with the RapidEye constellation. More rapid revisit times are a significant improvement for nations performing disaster response, which was the purpose of the RapidEye constellation. Additionally, the nanosat option would allow more nations to own their own satellite for off-peak (non-disaster) imaging data collection. As costs lower and production times shorten, nanosatellites are becoming increasingly feasible ventures for companies. Example nanosatellites: ExoCube (CP-10) , ArduSat , SPROUT Nanosatellite developers and manufacturers include EnduroSat , GomSpace , NanoAvionics , NanoSpace, Spire , Surrey Satellite Technology , NovaWurks , Dauria Aerospace , Planet Labs and Reaktor .

In July 2012, Virgin Orbit announced LauncherOne , an orbital launch vehicle designed to launch "smallsat" primary payloads of 100 kg (220 lb) into low Earth orbit , with launches projected to begin in 2016. Several commercial customers have already contracted for launches, including GeoOptics , Skybox Imaging , Spaceflight Industries , and Planetary Resources . Both Surrey Satellite Technology and Sierra Nevada Space Systems are developing satellite buses "optimized to

1620-531: The size of a soda can. The term "femtosatellite" or "femtosat" is usually applied to artificial satellites with a wet mass below 100 g (3.5 oz). Like picosatellites, some designs require a larger "mother" satellite for communication with ground controllers. Three prototype "chip satellites" were launched to the ISS on Space Shuttle Endeavour on its final mission in May 2011. They were attached to

1665-613: The successful Mars InSight lander mission. The two microsats accomplished a flyby of Mars in November 2018, and both continued communicating with ground stations on Earth through late December. Both went silent by early January 2019. A number of commercial and military-contractor companies are currently developing microsatellite launch vehicles to perform the increasingly targeted launch requirements of microsatellites. While microsatellites have been carried to space for many years as secondary payloads aboard larger launchers ,

1710-564: The ten years of nanosat launches prior to 2014, only 75 nanosats were launched. Launch rates picked up substantially when in the three-month period from November 2013–January 2014 94 nanosats were launched. One challenge of using nanosats has been the economic delivery of such small satellites to anywhere beyond low Earth orbit . By late 2014, proposals were being developed for larger spacecraft specifically designed to deliver swarms of nanosats to trajectories that are beyond Earth orbit for applications such as exploring distant asteroids. With

1755-417: The term "satellite swarm" or " fractionated spacecraft " may be applied. Some designs require a larger "mother" satellite for communication with ground controllers or for launching and docking with nanosatellites. Over 2300 nanosatellites have been launched as of December 2023. A CubeSat is a common type of nanosatellite, built in cube form based on multiples of 10 cm × 10 cm × 10 cm, with

1800-414: The use of satellite constellations , nanosatellites are increasingly capable of performing commercial missions that previously required microsatellites. For example, a 6U CubeSat standard has been proposed to enable a satellite constellation of thirty five 8 kg (18 lb) Earth-imaging satellites to replace a constellation of five 156 kg (344 lb) RapidEye Earth-imaging satellites, at

1845-612: Was a Japanese nanosatellite that was launched during the SS-520-5 sounding rocket test launch on 3 February 2018, with a mission to conduct store and forward data relay and Earth observation using a set of cameras. Developed by the University of Tokyo , the spacecraft was a low-cost 3U CubeSat , with a goal of realizing future cost-competitive nanosatellites in the global market by using domestic commercial products.

It was built by the University of Tokyo Intelligent Space Systems Laboratory , with funding allocated from the Japanese Ministry of Economy, Trade and Industry . The store and forward mission involved the satellite storing weak signal data from terrestrial terminals, and forwarding

2025-530: Was launched from Japan's Antarctic base. The first S-210 launch took place in 1966, and was retired in 1982. The first two launches of the full sized versions in took place between 1966 and 1967: they were both failures, with the motor case burning through. After redesign of the case and improved quality control the subsequent launch in August 1969 was successful. Following further successful tests in Japan in 1970–1971,
