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.
The Space Test Program (STP) is the primary provider of spaceflight for the United States Department of Defense (DoD) space science and technology community. STP is managed by a group within the Advanced Systems and Development Directorate, a directorate of the Space and Missile Systems Center of the United States Space Force. STP provides spaceflight via the International Space Station (ISS), piggybacks, secondary payloads and dedicated launch services.
AeroCube-3 is a single-unit CubeSat which was built and is being operated by The Aerospace Corporation, at El Segundo, California. It is the third AeroCube picosatellite, following on from AeroCube-1, which was lost in a launch failure in 2006, and AeroCube-2 which was successfully launched in 2007 but failed immediately after launch. Compared to its predecessors it contains several improvements in its infrastructure, including a redesigned power system, replacing the older system which was responsible for the loss of AeroCube-2. Its development was funded by the United States Air Force Space and Missile Systems Center, at Los Angeles Air Force Base.
CP6, also known as CP6 CubeSat, CalPoly CP-6, PolySat-6 or PolySat CP6 is a single-unit CubeSat which was built and operated by the California Polytechnic State University (CalPoly). It was primarily intended to perform a technology demonstration mission. The main experiment consisted of sensors to determine the spacecraft's attitude. Cameras on the satellite will be used to verify the data returned by the attitude sensors.
NanoSail-D2 was a small satellite built by NASA's Marshall Space Flight Center and Ames Research Center to study the deployment of a solar sail in space. It was a three-unit CubeSat, measuring 30 cm × 10 cm × 10 cm with a mass of 4 kg (8.8 lb). Its solar sail had an area of 10 m2 (110 sq ft), and was deployed in around five seconds.
Technology Education Satellite (TechEdSat) is a successful nano-sat flight series conducted from the NASA Ames Research Center in collaboration with numerous universities. While one of the principal aims has been to introduce young professionals and university students to the practical realm of developing space flight hardware, considerable innovations have been introduced. In addition, this evolving flight platform has tested concepts for Low Earth Orbit (LEO) sample return, as well as planetary nano-sat class mission concepts.
SpaceX CRS-4, also known as SpX-4, was a Commercial Resupply Service mission to the International Space Station (ISS), contracted to NASA, which was launched on 21 September 2014 and arrived at the space station on 23 September 2014. It was the sixth flight for SpaceX's uncrewed Dragon cargo spacecraft, and the fourth SpaceX operational mission contracted to NASA under a Commercial Resupply Services contract. The mission brought equipment and supplies to the space station, including the first 3D printer to be tested in space, a device to measure wind speed on Earth, and small satellites to be launched from the station. It also brought 20 mice for long-term research aboard the ISS.
Nanoracks LLC is a private in-space services company which builds space hardware and in-space repurposing tools. The company also facilitates experiments and launches of CubeSats to Low Earth Orbit.
Antares A-ONE mission was the maiden flight of Orbital Sciences Corporation' Antares launch vehicle including the ascent to space and accurate delivery of a simulated payload, the Cygnus Mass Simulator (CMS), which was launched 21 April 2013. It was launched from Pad 0A at the Mid-Atlantic Regional Spaceport (MARS), Wallops Flight Facility, Virginia. The simulated payload simulates the mass of the Cygnus cargo spacecraft. This dummy payload was sent into an orbit of 240 km × 260 km with an orbital inclination of 51.6°, the same launch profile it will use for Orbital's upcoming cargo supply missions to the International Space Station (ISS) for NASA.
BioSentinel is a lowcost CubeSat spacecraft on a astrobiology mission that will use budding yeast to detect, measure, and compare the impact of deep space radiation on DNA repair over long time beyond low Earth orbit.
LunIR is a nanosatellite spacecraft launched to the Moon collecting surface spectroscopy and thermography. It was launched as a secondary payload on the Artemis 1 mission on 16 November 2022.
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.
Firefly Alpha is a two-stage orbital expendable launch vehicle developed by the American company Firefly Aerospace to compete in the commercial small satellite launch market. Alpha is intended to provide launch options for both full vehicle and rideshare customers.
ArgoMoon is a CubeSat that was launched into a heliocentric orbit on Artemis 1, the maiden flight of the Space Launch System, on 16 November 2022 at 06:47:44 UTC. The objective of the ArgoMoon spacecraft is to take detailed images of the Interim Cryogenic Propulsion Stage following Orion separation, an operation that will demonstrate the ability of a cubesat to conduct precise proximity maneuvers in deep space. ASI has not confirmed nor denied whether this took place, but several images of the Earth and the Moon were taken.
Educational Launch of Nanosatellites (ELaNa) is an initiative created by NASA to attract and retain students in the science, technology, engineering and mathematics disciplines. The program is managed by the Launch Services Program (LSP) at NASA's Kennedy Space Center in Florida.
TROPICS(Time-Resolved Observations of Precipitation structure and storm Intensity with a Constellation of Smallsats) is a NASA constellation of six small satellites, 3U CubeSats, that will measure temperature and moisture profiles and precipitation in tropical systems with unprecedented temporal frequency. This data will enable scientists to study the dynamic processes that occur in the inner core of the storm resulting in rapid genesis and intensification. William Blackwell of the Massachusetts Institute of Technology's Lincoln Laboratory in Lexington, Massachusetts is the principal investigator. The constellation was initially planned to be delivered to orbit on three launches between June and July 2022. Due to the loss of the first two satellites after a launch failure in June 2022, the first satellites were delivered to orbit aboard a Rocket Lab Electron rocket on 7 May 2023.
NASA's Pathfinder Technology Demonstrator (PTD) Project is a series of tech demonstrations of technologies aboard a series of nanosatellites known as CubeSats, providing significant enhancements to the performance of these versatile spacecraft. Each of the five planned PTD missions consist of a 6-unit (6U) CubeSat with expandable solar arrays.
