NASA's Juno mission found that Jupiter's icy moon Europa produces 1,000 tons of oxygen every 24 hours. That's enough oxygen to keep a million people alive for a day, NASA reported this week. Some of it may get stuck in the ice, some may escape to space, and some may travel downward into Europa's subsurface ocean. NASAWhat NASA's Juno mission has done is shed more light on the total amount of oxygen that Europa's surface generates. Measuring oxygen on EuropaTo measure how much oxygen Europa's surface generates, scientists used the Jovian Auroral Distributions Experiment (JADE) instrument on board Juno.
