The Technological and Educational Nanosatellite, or TechEdSat, is a series of CubeSats built by San Jose State University students in partnership with Ames Research Center and ÅAC Microtec.
The first TechEdSat had a mission to evaluate Space Plug-and-play Avionics (SPA) from ÅAC Microtec, and was launched on an H-IIB carrier rocket from the Tanegashima Space Center on 21 July 2012 to the International Space Station, where it was deployed via the JAXA J-SSOD deployer. on 4 Oct 2012. It reentered to atmosphere on 5 May 2013.
TechEdSat-2 was planned as a 6U CubeSat, a collaboration between ÅAC Microtec in Sweden and NASA Ames.
TechEdSat-3p was a 3U CubeSat that was launched to the International Space Station on November 20, 2013 on a HTV-4 from Tanegashima, Japan and subsequently deployed into orbit using the JEM-Small Satellite Orbital Deployer. It tested an exo-brake to demonstrate a passive deorbiting.
TechEdSat-4 is a 3U CubeSat mission developed, integrated, and tested at NASA Ames in partnership with student interns from San Jose State University in California and the University of Idaho. The objective of the TechEdSat-4 mission is to demonstrate new technologies including satellite-to-satellite communications and an upgraded exo-brake device to demonstrate a passive deorbiting. TechEdSat-4 was launched as a secondary cargo payload on the Cygnus CRS Orb-2 ISS resupply mission. The launch vehicle was the Orbital Sciences Corporation Antares-120, launching from the Mid-Atlantic Regional Spaceport on Wallops Island, VA on July 13, 2014. TechEdSat-4 was deployed from the International Space Station via the NanoRacks CubeSat Deployer on March 4, 2015.
