Session
Technical Session VIII: New Missions II
Abstract
The TOMS-EP spacecraft is a part of NASA’s Mission to Plant Earth, sponsored by NASA/GSFC for an ozone mapping/surveillance mission. The mission requires a single instrument in a sun synchronous, noon, low earth orbit. The spacecraft must provide the mission capabilities and robustness of larger spacecraft within the weight and volume capabilities of the Pegasus LN, and at a relatively low cost, allowing the spacecraft carry a single instrument. Autonomy is provided for both deployment and safe hold modes, using the full functional redundancy provided. Contamination control is designed to protect the payload instrument. The subsystems were optimized to provide the required performance within weight and volume limits. The spacecraft design has been fully verified both functionally and for the operational environments through unit tests, test bed verification, and protoflight testing.
