【 摘 要 】

An In-Situ Resource Utilization (ISRU) mission has been proposed for Mars. The ISRU mission would process Oxygen from the Carbon Dioxide in the Martian atmosphere or create Methane and Oxygen from the Martian soil and atmosphere. The Rapid Cycle Adsorption Pump (RCAP) is a proposed technology for Carbon Dioxide separation from residual gases (mainly Nitrogen and Argon) and pressurization for downstream chemical processing from the Martian atmosphere. The RCAP works by using a temperature swing adsorption cycle. We talk about the current RCAP technology development efforts at NASA (modeling, manufacturing, testing, and adsorbent development) and discuss the thermal challenges that are specific to this technology.
