Picosatellite Solar Cell Testbed 2



Picosatellite Solar Cell Testbed 2 (PSSC 2), a US Air Force satellite, was launched from Cape Canaveral on 08 July 2011 at 15:29 UT by the Shuttle Atlantis. PSSC 2 is a miniaturized satellite operated by the United States Air Force as part of a technology demonstration program.

PSSC 2 is the second PSSC satellite, following PSSC 1, deployed from Space Shuttle Endeavour during STS 126 in 2008. It carries two technology demonstration experiments: Miniature Tracking Vehicle (MTV) and the Compact Total Electron Content Sensor (CTECS).

MTV will test the satellite's ability to function as a reference body for tracking stations while CTECS will observe the signals from occulting Global Positioning System satellites in order to study the density of the ionosphere. The satellite also carries cameras intended to capture the last images of a Space Shuttle in orbit, shortly after separation.

It remained attached during Atlantis' visit to the International Space Station and was deployed upon the undocking of shuttle Atlantis.
