Scientists Rule Out Human Survival on Europa Despite 1,000 Tons of Daily Oxygen

2 articles · Updated · Worldatlas.com · Jul 7

Summary

  • Jupiter’s moon Europa generates about 1,000 tons of oxygen every 24 hours, but scientists say humans still could not survive there with current technology.
  • Jupiter’s radiation would kill an unshielded person in less than a day, while Europa’s surface never warms above minus 260 degrees Fahrenheit and lacks a breathable atmosphere.
  • Europa remains scientifically compelling because researchers think a saltwater ocean beneath its ice may hold twice as much water as all of Earth’s oceans combined and could contain ingredients for life.
  • NASA’s Europa Clipper, launched in 2024, is due to reach Jupiter in 2030 and make 49 flybys to test whether the moon is potentially habitable despite its hostile surface.

Insights

Could life on Europa just be ancient Earth microbes? How will scientists know if they find our distant cousins?
If Clipper confirms a habitable ocean, what is the next step in the multi-billion-dollar quest to finally find life?
Europa’s water plumes have vanished. How will the Clipper mission now peek into its hidden, potentially life-bearing ocean?

Juno Lowers Europa’s Oxygen Estimate: Implications for Habitability and Future Missions

Overview

Juno's extended mission revealed that Europa's surface is constantly bombarded by ionized particles from Jupiter's magnetic field. These charged particles strike the moon's icy shell, breaking apart water-ice molecules and producing both hydrogen and oxygen. The JADE instrument on Juno collected new data by passing through Europa's torus, allowing scientists to better understand how these particles interact with the surface and drive oxygen production. This process not only erodes Europa's ice shell but also provides a more accurate estimate of the moon's oxygen levels, which is important for assessing its potential to support life.
