  • Contamination limiter for reducing outgassed volatile condensable materials from external sensitive optical and thermal surfaces of a spacecraft
    Patent number: 11684887
    Abstract: One embodiment includes a contamination limiter for a spacecraft. The contamination limiter includes a body having an interior. An inlet is fluidly coupled to the interior of the body. A collector plate is positioned within the interior of the body. A UV light source is directed at a surface of the collector plate. An exterior vent is fluidly coupled to the interior of the body. A volatile condensable material from the spacecraft is photofixed by the UV light exposure to the collector plate prior to venting through an exterior vent to an exterior of the spacecraft.
