Cryocooler

Cryocooler

The development of a 20 Watt 20 Kelvin cryocooler is a critical step in enabling zero boil-off of liquid hydrogen.

NASA does not currently have zero boil-off cryogenic technologies that will enable preserving liquid hydrogen propellant necessary for future exploration missions beyond low Earth orbit.

The development of a 20 Watt 20 Kelvin cryocooler is a critical step in enabling zero boil-off of liquid hydrogen. Active thermal control of cryogenic propellants is made possible by integrating a cryocooler to intercept and collect heat from the cryogenic tank support structure and/or a broad area cooled shield.
