Small Payload Quick Return
Small Payload Quick Return (SPQR) is a NASA Ames Research Center concept to return small payloads from orbit. The system uses an Exo-Brake, a parachute-like drag device for use in the low-pressure exosphere of Low Earth Orbit. This is the first part of a three part return system, operating from 350 to 100 km. Exo-Brake The first test of the Exo-Brake system from orbit began with the launching of the TechEdSat-3p nano-satellite from the International Space Station on November 19, 2013. TechEdSat-4 is expected to test an Exo-Brake with variable drag in 2014. TechEdSat-3p took over 60 days to deorbit, while TechEdSat-4 reentered in about 30 days. A newer Exo-Brake system was tested on TechEdSat-5, deployed from the ISS in 2017. It is a flexible cross shape that can be warped for steering during reentry. SOAREX Flights Several investigations related to the SPQR programs and TechEdSat have been flown on Sub-Orbital Aerodynamic Re-entry Experiments (SOAREX) sounding rockets flights. SOAREX-6 flew 27 November 2008 on an ATK Sub-orbital/Orion 50xl sounding rocket. SOAREX-7 flew 28 May 2009 aboard a Terrier-Orion sounding rocket launched from Wallops Flight Facility (WFF) in Virginia. A TDRV (Tube Deployed Re-entry Vehicle) was successfully tested after the flight
