A CubeSat is a type of miniaturized satellite for space research that is made up of multiple cubic modules of 10 cm × 10 cm × 10 cm size. CubeSats have a mass of no more than 1.33 kilograms (2.9 lb) per unit, and often use commercial off-the-shelf (COTS) components for their electronics and structure. CubeSats are put into orbit by deployers on the International Space Station, or launched as secondary payloads on a launch vehicle. As of 1 January 2021, more than 1350 CubeSats have been launched. More than 1200 have been successfully deployed in orbit and more than 90 have been destroyed in launch failures.
Lacrosse or Onyx is a series of terrestrial radar imaging reconnaissance satellites operated by the United States National Reconnaissance Office (NRO). While not officially confirmed by the NRO or the Government of the United States prior to 2008, there was widespread evidence pointing to its existence, including one NASA website. In July 2008, the NRO itself declassified the existence of its synthetic aperture radar (SAR) satellite constellation.
A small satellite, miniaturized satellite, or smallsat is a satellite of low mass and size, usually under 500 kg (1,100 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.
The National Space Organization is the national civilian space agency of Taiwan, part of the National Applied Research Laboratories under the auspices of the Ministry of Science and Technology. NSPO is involved in the development of space technologies and related research.
Future Imagery Architecture (FIA) was a program awarded to Boeing to design a new generation of optical and radar imaging US reconnaissance satellites for the National Reconnaissance Office (NRO). In 2005 NRO director Donald Kerr recommended the project's termination, and the optical component of the program was finally cancelled in September 2005 by Director of National Intelligence John Negroponte. FIA has been called by The New York Times "perhaps the most spectacular and expensive failure in the 50-year history of American spy satellite projects." Despite the optical component's cancellation, the radar component, known as Topaz, has continued, with four satellites in orbit as of February 2016.
TacSat-1 was an experimental satellite built by the Naval Research Laboratory (NRL) on behalf of the United States Department of Defense (DoD) Office of Force Transformation (OFT). It was the planned payload of the sixth launch of the SpaceX Falcon 1. It was however never launched into space. The second satellite in the series, TacSat-2, launched before TacSat-1 and this led to the cancellation of TacSat-1's launch.
The Near Earth Object Surveillance Satellite (NEOSSat) is a Canadian microsatellite using a 15-cm aperture f/5.88 Maksutov telescope, with 3-axis stabilisation giving a pointing stability of ~2 arcseconds in a ~100 second exposure. It is funded by the Canadian Space Agency (CSA) and Defence Research and Development Canada (DRDC), and searches for interior-to-Earth-orbit (IEO) asteroids, at between 45 and 55 degree solar elongation and +40 to -40 degrees ecliptic latitude.
During the second half of 2002, the Naval Research Laboratory studied the tactical application of space assets. Relatively new technologies and processes in the areas of microsatellites, affordable and quick-response launch vehicles, and the classified SIPRNet made tactical use of space assets possible in the relatively near term. The DoD's Office of Force Transformation (OFT) agreed with the core findings of the study and decided to start an Operationally Responsive Space (ORS) Initiative consisting of a series of experiments. TacSat-1 is the first experiment in this OFT initiative. The TacSat-1 experiment received go-ahead on 7 May 2003.
Negai☆″ is a Japanese satellite which launched in May 2010. It is a student-built spacecraft, which will be operated by Soka University, and is intended to be used for technology demonstration. The satellite is a single unit CubeSat, and will be used to test a field programmable gate array in orbit. As part of an outreach programme, it will carry the names of selected children, along with wishes they have made. The satellite will return images of the Earth, which will be given to the participating children.
USA-221, also known as FalconSat-5, is an American military minisatellite, which was launched in 2010. The fifth FalconSat spacecraft to be launched, it carries four technology development and ionospheric research experiments. The satellite was constructed and is operated by the United States Air Force Academy.
VesselSat-2 was a Luxembourgian microsatellite built and owned by LuxSpace, and operated by Orbcomm under lease. It carried a receiver for Automatic Identification System signals, used to track ships at sea. VesselSat-2 was the second of two VesselSat spacecraft, which were built by LuxSpace for Orbcomm, as replacements for the AIS capabilities of the failed Orbcomm-QL spacecraft.

BILSAT-1 was an earth observation satellite designed and developed by TÜBİTAK Space Technologies Research Institute and produced in Turkey as part of the Disaster Monitoring Constellation (DMC) project in the context of a show-how program led by DMC International Imaging of Surrey Satellite Technology (SSTL).
Nanoracks LLC is a private in-space services company which builds tools to allow for the re-purposing of in-space hardware and turn it into space stations.
OA-4, previously known as Orbital-4, was the fourth successful flight of the Orbital ATK uncrewed resupply spacecraft Cygnus and its third flight to the International Space Station (ISS) under the Commercial Resupply Services (CRS-1) contract with NASA. With the Antares launch vehicle undergoing a redesign following its failure during the Orb-3 launch, OA-4 was launched by an Atlas V launch vehicle. Following three launch delays due to inclement weather beginning on 3 December 2015, OA-4 was launched at 21:44:57 UTC on 6 December 2015. With a liftoff weight of 7,492 kg (16,517 lb), OA-4 became the heaviest payload ever launched on an Atlas V. The spacecraft rendezvoused with and was berthed to the ISS on 9 December 2015. It was released on 19 February 2016 after 72 days at the International Space Station. Deorbit occurred on 20 February 2016 at approximately 16:00 UTC.
EQUULEUS is a nanosatellite of the 6U CubeSat format that will measure the distribution of plasma that surrounds the Earth (plasmasphere) to help scientists understand the radiation environment in that region. It will also demonstrate low-thrust trajectory control techniques, such as multiple lunar flybys, within the Earth-Moon region using water steam as propellant. The spacecraft was designed and developed jointly by the Japan Aerospace Exploration Agency (JAXA) and the University of Tokyo.
RSat-P is a microsatellite built by the United States Naval Academy (USNA) in Annapolis, Maryland. The small spacecraft is a 3U CubeSat intended to demonstrate capabilities for minor in-orbit repair of a much larger, conventional spacecraft.
SEDSAT-1 is a U.S. amateur radio satellite built by students and developed at the University of Alabama in Huntsville (UAH).
