The technical papers were not presented in person due to the inability to hold the event as scheduled in Lisbon, Portugal because of the COVID-19 global pandemic.The Orion Laser Air Monitor System (LAMS) is a tunable laser spectrometer that will monitor oxygen, carbon dioxide, and water vapor levels in the Orion Multipurpose Crew Vehicle (MCPV) cabin and in the space suit loop. LAMS, designed to be small, lightweight, and low power, can nonetheless accurately measure a wide dynamic range of analyte concentrations over relatively wide pressure and temperature ranges despite not using gas pumps, flow, or pressure controllers. Additionally, the LAMS hardware and electronics are capable of meeting stringent Crit-1R requirements for human life support. This is the first time a tunable laser spectrometer is being used for atmosphere monitoring and feedback control for ECLSS hardware in a manned spaceflight environment.application/pdfengLaser spectrometerTunable laser diodeLife support sensorAtmosphere monitoringHuman rated spaceflightPresentation
