A cryogenic propellant depot and sunshield are provided for operation in earth orbit to fuel or refuel other space vehicles. The sunshield is deployed to effectively mitigate solar radiation emanating from the earth and the sun thereby providing a long term storage solution for cryogenic fluids prone to boil-off. The depot has supporting subsystems to include station keeping equipment and communication equipment so that the depot can be independently controlled. Inflatable booms are used to deploy the sunshield in a desired pattern around the depot.
1. In combination, a cryogenic propellant depot incorporating an integral sunshield, said combination comprising: a tank having a sidewall enclosing a quantity of cryogenic liquid therein;a bulkhead attached to an end of said tank, said bulkhead having an interior open space defining a thermal isolation reservoir between the tank and the bulkhead;a docking port formed on said bulkhead and communicating with an interior of said tank for selectively evacuating liquid in said tank; anda sunshield attached to said tank, said sunshield having a first smaller ...
