Description:

• TechEdSat 3 (Technical and Educational Satellite 3) is a 3U CubeSat. 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.
• The TechEdSAT-3 will be the first flight test of an Exo-Brake passive de-orbit system. Building on the predecessor, TechEdSAT-3p is a triple cubesat (3U) with a set of dual advanced avionics systems powered by the previous core system. In 2U of the packaging (roughly 2/3 of the volume), there is stowed an erectable deployment system that would place the Exo-Brake in the desired orientation. Scaled as a 10 day experiment, the deployed system has the ballistic coefficient of 5 kg/m2 - and is constructed as a tension-based structure that would not entangle itself. During the de-orbit process, GPS data from the dual avionics as well as collected TLE (Two Line Elements) provided by the USSTRATCOM will be used to analyze the flight dynamics and compared to computational models. This experiment will be the antecedent of related experiments at larger scale (e.g., for a 1.5 day de-orbit) and controllability. The effort was built by teams from the San Jose State University

Mission details:

• TechEdSat 1 was launched on board of HTV 4 to the International Space Station, from where it will be deployed.
• The last of the cubesats delivered by HTV-4, TechEdSat-3p, was deployed from the Kibo module at 0758 UTC on Nov 20, 2013.
