The ISS uses filtration, distillation and catalytic reactors to purify wastewater into safe drinking water for astronauts.

Prefer Newsweek on Google to see more of our trusted coverage when you search. Researchers have developed a new technique that can split water in near-zero gravity to produce oxygen and hydrogen in a ...

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 ...

Gravity, in the literal sense, keeps everyone (and everything) on Earth grounded. It acts as the anchor that prevents objects from floating skyward. For humans, it’s a leash that stops us from ...

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 ...
