About Cryogenic Propellant Storage and Transfer (CPST)

Artist concept of Cryogenic Propellant Storage and Transfer"The science of today is the technology of tomorrow."
-- Edward Teller, 20th century American physicist

Cryogenic propellants -- gasses under normal conditions, chilled to subfreezing temperatures and condensed to form highly combustible liquids -- provide high-energy propulsion solutions critical to future, long-term human exploration missions beyond low-Earth orbit. The challenge is to develop means of storing and transferring these propellants in space for long duration, and preventing temperature fluctuations that contribute to fuel losses due to "boil off."

The Cryogenic Propellant Storage & Transfer project, or CPST, will demonstrate the capability to safely and efficiently store, transfer and measure cryogenic propellants -- enabling next-generation flight vehicles to store large quantities of fuel for their journeys of discovery.

Led by NASA's Glenn Research Center in Cleveland, the project is formulating a mission concept and conducting ground demonstrations for a Technology Demonstration Flight in 2018.
