Randomized trial demonstrates improved CO2 control with new sorbents in space missions, suggesting extended mission times.

The aim is to enhance the removal of CO2 and water from the xEMU while reducing ammonia emissions.
Developed new sorbents that potentially outperform existing amine-based sorbent SA9T.
Characterized sorbent cycle times based on CO2 partial pressure in simulated EVA missions.
Used rapid screening methods to derive performance data under relevant conditions.
New sorbents exhibited a net reduction in the number of cycles required during EVA missions, thus conserving energy.
Identified sorbents emitted less ammonia compared to the SA9T sorbent.
Achieved a better CO2 uptake capacity than the existing sorbent SA9T.

Wickham et al. (2024) studied this question.
