Using Paraffin PCM, Cryogel and TEC to Maintain Comet Surface Sample Cold from Earth Approach through Retrieval

摘要

An innovative thermal design concept to maintain comet surface samples cold (for example, 263K, 243K or 223K) from Earth approach through retrieval is presented. It uses paraffin phase change material (PCM), Cryogel insulation and thermoelectric cooler (TEC), which are commercially available.
