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 paper is a follow-up to the 2020 and 2023 ICES papers which covered flight unit build and testing results for Artemis missions 2 and 3. This paper covers design updates, flight unit build, and test results for the Artemis missions 4 and 5.
