Atmospheric Neutral Density Experiment - 2 (ANDE-2) consists of two microsatellites launched from the Shuttle payload bay, that will measure the density and composition of the Low Earth Orbit (LEO) atmosphere while being tracked from the ground.
Data will be used to better predict the movement and decay of objects in orbit.
Originally designed as passive payloads, both satellites were turned into research projects of various participating highschools and universities. Radio Amateurs participated in the program as they acquired all satellite data transmitted via radio.
