Technology Education Satellite (TechEdSat) is a successful nano-sat flight series conducted from the NASA Ames Research Center in collaboration with numerous universities (San Jose State University, University of Idaho, University of California, University of Minnesota, and Smith College). 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.

The first TechEdSat (later renamed "TechEdSat-1" or "TES-1")[2][3] was a 1U-Cubesat designed to evaluate Space Plug-and-play Avionics (SPA) designed in Sweden by ÅAC Microtec. It was also originally intended to perform a communications experiment utilizing the Iridium and Orbcomm satellite phone network,[4] although this function was disabled before launch.[5] TechEdSat was deployed into orbit from the International Space Station (ISS) on 4 October 2012. It reentered to atmosphere on 5 May 2013.[6]

An Iridium transceiver flew aboard the PhoneSat v2a CubeSat as the TechEdSat-2 mission, separate from the spacecraft originally planned as TechEdSat-2.[13]
Alexander, also known as PhoneSat 2.0 Beta or PhoneSat v2a is a technology demonstration satellite operated by NASA's Ames Research Center, which was launched on 21 April 2013. Part of the PhoneSat programme, it was one of the first three PhoneSat spacecraft, and the first Phonesat-2.0 satellite, to be launched. A PhoneSat-2.0 satellite, Alexander, was built to the single-unit (1U) CubeSat specification, and measures 10 cm (3.9 in) in each dimension. The satellite is based around an off-the-shelf Samsung Electronics Nexus S smartphone which serves in place of an onboard computer. The satellite is equipped with a two-way S-band transponder and solar cells for power generation. The spacecraft uses the phone's gyroscopes, along with a GPS receiver, to determine its position and orientation, and a system of reaction wheels and magnetorquer coils for attitude control.[14]

TechEdSat-3p was the third spacecraft flown in the TechEdSat series. Its dimensions were approximately 30 cm x 10 cm x 10 cm, or three CubeSat units long, making it three times larger than TechEdSat-1. TechEdSat-3p was launched to the International Space Station (ISS) on 3 August 2013 from Tanegashima Space Center, Japan on the Kounotori 4 (HTV-4) International Space Station cargo resupply mission and subsequently deployed into orbit by the JEM-Small Satellite Orbital Deployer (J-SSOD).
TechEdSat-3p was the first satellite of the TechEdSat series to include an exo-brake, a parachute-like drag device to demonstrate passive deorbit capability.[15] The deployment of an exo-brake increases the surface area of a satellite, increasing its coefficient of drag in the thin upper atmosphere and causing the satellite to deorbit faster than it otherwise would. This technology could be used to more quickly dispose of satellites in Low Earth Orbit that have completed their missions, decreasing the amount of potentially hazardous debris in space. The exo-brake is currently being developed for use as part of the Small Payload Quick Return (SPQR) concept, which would enable science materials to be returned to Earth from the International Space Station whenever is most convenient for scientists rather than just a few times per year aboard a returning cargo resupply vehicle.
According to smallsat logistics company ÅAC Microtech, a main power distribution board designed for TechEdSat-1 was reused on the TechEdSat-3p mission.[16]

TechEdSat-8 (Technical and Educational Satellite-8) was CubeSat 6U. It was built as a conjoined project between San Jose State University (SJSU) and the University of Idaho as a collaborative engineering project, with oversight from the NASA Ames Research Center. It was a technology demonstration mission to further develop and demonstrate the Exo-Brake system through, designed for continued operation in high temperature environments, the full recovery of a payload. It featured a semi-autonomous control system to target the entry face point, as well as capabilities to measure a unique ablation device on the forebody. This technology, known as a "Hot Exo-Brake" could enable more precisely-targeted atmospheric reentries. An ablation device was also flying on the spacecraft.
History
editTechEdSat-8 was selected in 2017 by the CubeSat Launch Initiative (CSLI) of the NASA to be launched as part of the ELaNa program. TechEdSat-8 was originally planned to launch with the Cygnus NG-10 (17 November 2018) cargo resupply mission to the International Space Station as part of the ELaNa program, but instead was launched aboard the SpaceX CRS-16 ISS cargo resupply mission at 18:16 UTC on 5 December 2018,[32] arriving at the International Space Station (ISS) on 8 December 2018.[33][34]
Deployment
editTechEdSat-8 was deployed into orbit by the Kibō JEM-Small Satellite Orbital Deployer (J-SSOD) at 16:45 UTC on 31 January 2019.[35]
Mission
editThe satellite established communication with controllers and, as of 20 February 2019, was reportedly performing well in advance of a targeted reentry.[36] The satellite failed shortly after deployment due to a loss of power from its solar panels, and re-entered in the atmosphere of Earth on 20 April 2020.[37][38]

TechEdSat-10 (TES-10) was a 6U (1 x 6U) (previously announced as 3U) CubeSat that was selected in 2018 to launch as part of the ELaNa program.[39]
Launch
editOn 15 February 2020, TechEdSat-10 was launched to the International Space Station (ISS) aboard the Cygnus NG-13 cargo spacecraft.[40]
Deployment
editDeployed on 13 July 2020, TechEdSat-10 tested radio communication devices, precision deorbit technologies for National Oceanic and Atmospheric Administration (NOAA) and others, radiation tolerant electronics, and artificial intelligence hardware for future experiments.[41][37][40]
Mission
editThe mission demonstrated increased storage and power capabilities that could enable future science and exploration using small spacecraft beyond low-Earth orbit. Included on TechEdSat-10 were improvements over previous CubeSat technologies in the areas of communications and radio systems, and new propulsion techniques.[42]
As the tenth iteration in the Technology Educational Satellite (TES) series, TechEdSat-10 built upon a history of the program's innovative work with early career researchers, students, and volunteers. TechEdSat-10 contained 150 watt-hours of power storage, eight radios, nine processors, and a graphics processing unit. Additionally, the small satellite carried four cameras, including a stereoscopic virtual reality camera experiment.[42]
Like several TechEdSat missions before it, this mission demonstrated the exo-brake technology in its largest iteration to date. The exo-brake was designed to deploy an umbrella-like "brake" to increase drag and take a small satellite out of orbit. This mission, the exo-brake could be controlled or modulated by commands from the ground in order to target a re-entry point. In the future, this could enable sample return missions from orbit and future planetary missions.[42]

TechEdSat-15 was a 3U CubeSat. It was launched on 1 October 2022 as a rideshare payload on a Firefly Alpha rocket. Despite it being its first mission reaching Earth orbit, due to a lower-than-intended deployment orbit most of the satellites re-entered before reaching their intended design life.[43]
Future TechEdSats
editTechEdSat-9 and TechEdSat-11 are planned to fly at some point in the future.[44] TechEdSat-9, like TechEdSat-10, is planned to test radio communication technologies for National Oceanic and Atmospheric Administration (NOAA) and others.[37]
TechEdSat-12 will test technologies for the tracking and identification of small satellites. It will carry a radio-frequency identification (RFID) tag, a radar reflector, and an L-band antenna. It was selected for launch in February 2020 by NASA's CubeSat Launch Initiative, and will be delivered to orbit on a launch contracted through the ELaNa program.[45]
