context_page_description: Technology Education Satellite is a class of CubeSats built by San Jose State University and University of Idaho students in partnership with NASA's Ames Research Center. These satellites have tested communication technology for smallsats, and have contributed to the development of the Small Payload Quick Return concept.
context_section_description: TechEdSat-3p was the third spacecraft flown in the TechEdSat series. Its dimensions were approximately 30*10*10 cm, or three CubeSat units long, making it three times larger than TechEdSat-1. TechEdSat-3p was launched to the International Space Station on 20 November 2013 from Tanegashima, Japan on the HTV-4 International Space Station cargo resupply mission and subsequently deployed into orbit by the JEM-Small Satellite Orbital Deployer. 
  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. 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 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.
