Purdue University researchers are collaborating with NASA to study cryogenic liquids in zero gravity, leading to the possibility of propellant depots and refueling spacecraft in orbit. As we plan for ...

Today's astronauts are able to survive largely on freeze-dried, canned and dehydrated foods, but there are limitations in both nutrition and flavor to these dietary regimes. Refrigeration in space is ...

As we plan for future interplanetary spaceflight, one major aspect remains untested: refueling in space. That's because most rocket propellants are cryogenic liquids whose long-term behavior in space ...
