DOD Pico-Satellite known as ANDE released from the STS-116 shuttle payload bay

S116-E-07837 (21 Dec. 2006) --- As seen through windows on the aft flight deck of Space Shuttle Discovery, a Department of Defense pico-satellite known as Atmospheric Neutral Density Experiment (ANDE) is released from the shuttle's payload bay by STS-116 crewmembers. ANDE consists of two micro-satellites which will measure the density and composition of the low Earth orbit (LEO) atmosphere while being tracked from the ground. The data will be used to better predict the movement of objects in orbit.
