Autonomous Ion Mass Spectrometer Sentry (AIMSS)
Summary
The Department of Energy is seeking an Autonomous Ion Mass Spectrometer Sentry (AIMSS) to provide high‑resolution ion composition measurements for space weather forecasting, satellite health monitoring, and space station operations. The instrument’s ability to distinguish nitrogen and oxygen ions addresses a critical gap in current orbital mass spectrometers and supports both scientific research and defense space domain awareness.
