Backdropped by Earth's horizon and the blackness of space, a Department of Defense pico-satellite known as Atmospheric Neutral Density Experiment 2 (ANDE-2) is photographed after its release from Space Shuttle Endeavour'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.
