Abstract: Upcoming space missions will require sustained human presence for longer periods than ever before. Space exposes astronauts to demanding conditions, including microgravity, radiation, rapid light-dark cycles, and hazardous chemicals. Gas sensors will be pivotal in preserving astronaut health by providing critical health data and space-resolved environmental information. Here, I will discuss recent progress on gas sensors to meet the key needs of remote molecular sensing in space exploration. Two showcases will be highlighted that are currently explored as part of our two ESA Discovery projects (I-2023-05181 and I-2023-05536): Firstly, a headset for breath analysis to monitor biomarkers connected to space-related health challenges like gut microbiome, muscle activity, cardiovascular health, hepatic and renal function, and circadian rhythm. Secondly, sensor networks for distributed air quality monitoring that may support the adherence to environmental exposure guidelines in space-related fabrication infrastructure or in space vehicles and habitats.
