There might be more liquid water under the ice of Europa — one of Jupiter’s moons — than in all of Earth’s oceans combined. That sentence still stops me every time I process it. NASA’s Europa Clipper spacecraft launched in October 2024 and will reach Jupiter in 2030, but in 2026 it’s already well into its journey and producing science along the way. Here’s what the mission is about and why it might be the most consequential space science of our lifetime. For more detail, see our analysis of drake equation calculator.

Europa: Why This Moon Matters
Europa is approximately the size of Earth’s moon, but its interior is heated by tidal forces from Jupiter’s enormous gravity — a process that keeps a liquid ocean estimated at 60–150 km deep beneath an icy surface roughly 10–30 km thick.[1] The ocean has been in contact with the rocky seafloor for billions of years, creating conditions that, on Earth, are exactly where life thrives: hydrothermal vent systems.

The Hubble Space Telescope has detected plumes of water vapor erupting from Europa’s surface, suggesting the ocean is actively interacting with the surface — a finding that enormously simplifies the question of how to sample it. You may not need to drill through 20 km of ice.
I believe this deserves more attention than it gets.
What Europa Clipper Will Actually Do
The spacecraft will not land on Europa or drill through the ice. Instead, it will make approximately 49 close flybys over 4 years, using a suite of nine scientific instruments to characterize the ocean, the ice shell, and the surface chemistry.[2] Key instruments include:
