TECHNICAL ABSTRACT (Limit 2000 characters, approximately 200 words)
NASA has identified a need for higher heat rejection temperatures due to an equatorial lunar mission profile, where surface temperatures reach 400 K. To meet this need for space exploration vehicles to reject waste heat to high temperature heat sinks, Mainstream proposes adapting our oil-less vapor-compression (V-C) refrigeration compressor technology for operation at high temperature and high lift. Vapor-compression systems use two-phase heat transfer which reduces component size and mass over single-phase heat pumping cycles such as reverse-Brayton or Stirling. Mainstream?s current oil-less V-C compressor technology is gravity-insensitive, has a long operating life, can be scaled to match various heat loads, and has been mission-proven on the international space station (ISS) placing it at a TRL 9. The proposed development effort will extend this compressor technology to operation at high temperatures and high lift, to which it is inherently well-suited. The resulting compressor will be an enabling technology for the needed high temperature heat pumping systems.

POTENTIAL NASA COMMERCIAL APPLICATIONS (Limit 1500 characters, approximately 150 words)
The proposed research is targeted at enabling equatorial lunar exploration. NASA has identified a need for improved heat rejection systems in this environment, where surface temperatures can reach 400 K. The required heat rejection temperature exceeds the maximum heat rejection temperature of commercially available compressors. Our technology will enable space-based heat pumping systems at these temperatures. Mainstream expects that this will result in other NASA applications, such as non-lunar exploration vehicles with very high heat rejection loads.

POTENTIAL NON-NASA COMMERCIAL APPLICATIONS (Limit 1500 characters, approximately 150 words)
In addition to NASA?s lunar exploration mission profile, Mainstream?s compressor technology has potential to benefit any space-based system that must reject large amounts of heat through radiation. In these cooling systems, radiators are almost always the largest contributor to size and weight. By increasing the rejection temperature through a lifting cycle, such as the V-C refrigeration cycle, radiator size and weight can be significantly reduced. It can be assumed that any satellite or exploration vehicle that has high electric power consumption (1000s of watts or greater) is going to have large heat rejection requirements, due to the inherent inefficiencies of any real system. These high power satellites could potentially benefit from a lifting cycle.

TECHNOLOGY TAXONOMY MAPPING (NASA's technology taxonomy has been developed by the SBIR-STTR program to disseminate awareness of proposed and awarded R/R&D in the agency. It is a listing of over 100 technologies, sorted into broad categories, of interest to NASA.)
