As seen through windows on the aft flight deck of Space Shuttle Endeavour, a Department of Defense pico-satellite known as Atmospheric Neutral Density Experiment 2 (ANDE-2) is released on 30 July 2009 from the shuttle’s payload bay by STS-127 crew members. ANDE-2 consists of two spherical 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. high res (0.7 M) low res (102 K)
