A CubeSat is a class of small satellite with a form factor of 10 cm (3.9 in) cubes. CubeSats have a mass of no more than 2 kg (4.4 lb) per unit, and often use commercial off-the-shelf (COTS) components for their electronics and structure. CubeSats are deployed into orbit from the International Space Station, or launched as secondary payloads on a launch vehicle. As of December 2023, more than 2,300 CubeSats have been launched.
A small satellite, miniaturized satellite, or smallsat 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 the construction of small satellites may include the lack of sufficient power storage or of room for a propulsion system.
PhoneSat is an ongoing NASA project of building nanosatellites using unmodified consumer-grade off-the-shelf smartphones and Arduino platform and launching them into Low Earth Orbit. This project is part of NASA's Small Spacecraft Technology Program and was started in 2009 at NASA Ames Research Center.
NG-11, previously known as OA-11, is the twelfth flight of the Northrop Grumman robotic resupply spacecraft Cygnus and its eleventh flight to the International Space Station under the Commercial Resupply Services (CRS-1) contract with NASA. The mission launched on 17 April 2019 at 20:46:07 UTC. This is the last mission from the extended CRS-1 contract; follow-up missions are part of the CRS-2 contract. Cygnus NG-11 was also the first mission to load critical hardware onto Cygnus within the last 24 hours prior to launch, a new Antares feature.
GhanaSat-1 was the first Ghanaian nanosatellite to be launched into space. It was designed and built in two years in conjunction with the Kyushu Institute of Technology Birds-1 program, which has the goal of helping countries build their first satellite.
Mazaalai was a Mongolian nanosatellite CubeSat that was launched into space on 3 June 2017 as part of the SpaceX CRS-11 mission.
BRAC Onnesha was the first nanosatellite built in Bangladesh to be launched into space. The satellite was designed and built in conjunction with Kyushu Institute of Technology Birds-1 program, which has the goal of helping countries build their first satellite. It was designed and built over a two-year period.
Nigeria EduSat-1 was a Nigerian nanosatellite built by the Federal University of Technology Akure (FUTA), created in conjunction with the Japanese Birds-1 program. It was Nigeria's first satellite built by a university. It was launched from the Japanese Kibō module of the International Space Station, being brought to the station as part of SpaceX CRS-11.
Birds-1 was the first iteration of a multinational program called the Joint Global Multi-Nations Birds Satellite project, or Birds project, to help countries build their first satellite. The Japanese Kyushu Institute of Technology (KIT) supported the design and fabrication of the satellites. The constellation was launched by a Falcon 9 rocket to the International Space Station on 3 June 2017, as part of CRS-11, where it was released from the Kibō module into space. Japan, Ghana, Mongolia, Nigeria, and Bangladesh participated in the Birds-1 program, all building identical satellites for the constellation.
The Philippine Scientific Earth Observation Microsatellite (PHL-Microsat) was a satellite program carried by the Department of Science and Technology (DOST) of the Philippines in cooperation with the Tohoku and Hokkaido University of Japan.
Maya-1 was a Filipino nanosatellite. It was developed under the Philippine Scientific Earth Observation Microsatellite program (PHL-Microsat) and was jointly implemented by the University of the Philippines and the Department of Science and Technology as part of the Kyushu Institute of Technology-led multinational second Joint Global Multi-nations Birds Satellite (Birds-2). Maya-1 was the first nanosatellite of the Philippines.
BHUTAN-1 was the first Bhutanese nanosatellite to be launched into space. The satellite was built during Kyushu Institute of Technology's Birds-2 program. The Birds program helps countries fly their first satellite. BHUTAN-1 was launched into orbit aboard the SpaceX CRS-15 mission on 29 June 2018. It was deployed from the Kibō module of the International Space Station (ISS) on 10 August 2018. The satellite had cameras to image the Earth.
The Space Technology and Applications Mastery, Innovation and Advancement is a space technology program by the Philippine government. It is considered as the successor program to the Philippine Scientific Earth Observation Microsatellite (PHL-Microsat) program, a cooperation between the Philippine government and Japanese universities to develop microsatellites. The program is funded under the Department of Science and Technology.
UiTMSAT-1 was a Malaysian nanosatellite, built primarily by Universiti Teknologi MARA (UiTM) as part of the multi-nation Birds-2 project. The 1U CubeSat was launched into space on 29 June 2018 and deployed from the International Space Station (ISS) on 10 August 2018.
Simulation-to-Flight 1 (STF-1) is a microsatellite built by the Katherine Johnson Independent Verification and Validation Facility (IV&V) in Fairmont, West Virginia with the collaboration of the West Virginia Space Grants Consortium and West Virginia University.
Raavana-1 was the first Sri Lankan satellite. The CubeSat-sized satellite was launched as part of the Cygnus NG-11 mission to the ISS on 17 April 2019. On 17 June 2019, the satellite was deployed into orbit from the ISS.
Maya-2 was a Filipino nanosatellite. It succeeded Maya-1, the first Filipino nanosatellite, which was deorbited in November 2020.
KITSUNE was a nanosatellite developed by the HAK consortium, which consists of Haradaseiki Kogyo, Addnics Corporation, and Kyushu Institute of Technology (Kyutech). The spacecraft was a 6U CubeSat, and carried a high-resolution camera for Earth observation. KITSUNE was carried to the International Space Station (ISS) on board Cygnus NG-17, and was deployed from the ISS's Kibō Module on 24 March 2022 12:10 UTC. The deployment service of KITSUNE was provided by Mitsui Bussan Aerospace.
