Mainstream Engineering Awarded Contract from NASA to develop a Toxicity Mitigating Single-Fluid Cooling System for Manned Spacecraft
The thermal control systems for manned spacecraft are typically two-loop designs where a low freezing point toxic liquid is used, exterior to the manned vessel, to reject heat through the radiator array. A single-phase thermal loop inside the manned vessel that uses a non-toxic liquid is used for payload cooling and space conditioning. This architecture is necessary for crew safety because very low freezing point fluids are somewhat toxic or untested but come with a mass penalty due to the need for extra components and two loops instead of a single loop. Mainstream has developed a single loop architecture that uses toxicity mitigating technology.
