TechEdSat-4

NORAD ID: 40455
Launched: Aboard Cygnus Orb-2 Spacecraft
Released from ISS: March 4, 2015 - 01:20 UTC
Origin: USA
Type: 3U CubeSat
Mass: 3 Kilograms
Inclination: 51.6°

Re-Entry Prediction: April 3, 2015 - 09:01 UTC +/- 51 Minutes
Re-Entry Zone: Unknown

TechEdSat-4 flew an Exo-Brake to orbit that was deployed once the satellite was released to demonstrate a Passive De-Orbit System for satellites. The Exo Brake is a deployable device for use in free molecular flow regimes in an exo-atmosphere environment. The device is a tension based structure that has a number of advantages over other designs such as high stability and the possibility of drag modulating to provide targeting capability.
As part of its demonstration in orbit, TechEdSat's Exo-Brake would be deployed to begin a 10-day de-orbit experiment during which the GPS unit of the satellite provides position data that is coupled with Earth-based tracking data to model the exo-atmospheric descent of the satellite. TechEdSat was to have a high ballistic coefficient of 5kg/m² leading to a rapid orbital decay.
