A System Level Mass and Energy Calculation for a Temperature Swing Adsorption Pump Used for In-Situ Resource Utilization (ISRU) on MarsMars ISRU converts atmospheric CO2 to generate O2 and CH4. Reduces launch mass, thus mission cost. Increases mission duration and independence. CO2 acquisition system must: a) Reliably extract CO2 over the varying Martian environment. 1) approx. 0.67-0.93 kPa pressure and 2) 125 C to 40 C. b) Provide and compress high purity gas to chemical plants. 1) Separate N2, Ar2, etc. from approx. 95% CO2 atmosphere and 2) Current pressure targets: 50 kPa-500 kPa.
