Atmospheric Neutral Density Experiment
Appearance
The Atmospheric Neutral Density Experiment (ANDE) consists of two spherical satellites that are designed to measure the affects of atmospheric drag on spacecraft. ANDE is part of the DoD's Space Test Program.
ANDE was deployed from the Space Shuttle Discovery on 21 December 2006 near the end of the STS-116 ISS servicing mission.
The ANDE-FACL satellite deployed and is functioning, however the ANDE-MAA failed to deploy after it became stuck in its launch canister.[1]
