Abstract: Since the first Technology Education Satellite (TES) in 2012, the team from NASA Ames has flown an iterative series of nano-satellites with a variety of evolving experiments. The most recent, TES-10, will launch to the International Space Station (ISS) on February 9, 2020, and be subsequently jettisoned. TES-10’s attributes include having the highest power density of current NASA nano-satellites while incorporating eight microprocessors (including an NVDIA GPU), eight transmitters, and a unique, targeted, de-orbit system (known as an Exo-Brake). The flight series has successfully used the Iridium SBD modems for rapid command/control and is presented as a potential ‘TDRS for nano-sats.’ The presentation will include a detailed description of the COM subsystems, including the upcoming Iridium and Globalstar comparison tests. In addition, the ‘Lunar’ and ‘Mars’ radio will be discussed, which may help enable future interplanetary nano-sat missions.
Bio: M. Murbach is the Principal Investigator/PM of TechEdSat with of 25 years of flight experiments spanning balloons, sub-orbital rockets (the SOAREX series – Sub-Orbital Aerodynamic Re-Entry EXperiments), and nano-satellites (TES-n series; Nano-Orbital Workshop-NOW). Professional interests include hypersonics, propulsion, nano-spacecraft, and human/robotic planetary missions. He is an Adjunct Professor at San Jose State University. Education included Harvey Mudd College, San Jose State University, and Stanford University.
