Atmosphere Monitor
Multi-Gas Mass Spectrometer + Pressure Sensor Array
Atmosphere monitoring suite with mass spectrometer measuring composition + multi-zone pressure sensors detecting leaks.
Purpose
Atmosphere monitoring suite with mass spectrometer measuring composition + multi-zone pressure sensors detecting leaks.
Context
Child of L2-HAB-ATMO within the Lunar Ark system
Principles
- ▸Mass spectrometer measures O2, CO2, N2, H2O, trace gases
- ▸Per-zone pressure sensors for leak localisation
- ▸Hourly composition snapshots
- ▸Anomaly detection for breach + system fault
- ▸Long-mission data history
Typical implementations
- ▸ISS MCA (Major Constituent Analyzer) heritage
- ▸MSOLO mass spectrometer (PRIME-1 IM-2)
- ▸ESA gas monitoring
Lunar considerations
- ▸Closed-loop atmosphere requires precise monitoring
- ▸Rad-tolerant mass-spec
- ▸Long-life calibration
