This week, a SpaceX executive said their company is the latest to feel the impact of the liquid oxygen shortage.

The science pros at The King of Random mix liquid oxygen in a bold experiment to reveal its fascinating effects.

While a much larger version would be required to make liquid-oxygen fuel for a rocket, MOXIE is sized to produce about the amount of oxygen an active person needs to breathe.

The liquid oxygen needed to fuel the flight is needed in hospitals, where doctors use the important resource to keep dangerously sick COVID-19 patients alive.

Future Mars astronauts could make rocket fuel on the Red Planet using air, water and sunlight, a new study finds. The technology could fuel the astronauts' flights back to Earth.
