Searching for Life on Europa? Going Under the Ice

TL;DR

Europa's icy oceans hold potential for alien life; NASA's EUROPA mission plan explores drilling beneath Europa's ice shell.

Transcript

We’re now learning that icy worlds seem to be the best places in Solar System where life could be hiding. Worlds like Europa and Enceladus, which have vast oceans of liquid water beneath a shell of water ice. And just in the last year, astrobiologists announced that hardy forms of Earth life should be able to thrive in these oceans, feeding off hyd... Read More

Questions & Answers

Q: What makes icy worlds like Europa and Enceladus potential hotspots for finding alien life?

Icy worlds like Europa and Enceladus have vast liquid water oceans beneath their ice shells, providing a potential habitat for life forms to thrive.

Q: What is the EUROPA mission plan and how does it aim to explore Europa's under-ice regions?

The EUROPA mission plan involves deploying cryobots to drill through Europa's ice shell and release hydrobots to explore the under-ice oceans for signs of life.

Q: How does Europa's proximity to Jupiter affect its environment and the potential for life?

Europa's proximity to Jupiter results in high radiation exposure, but also allows for tidal interactions that maintain liquid water oceans under the ice, creating a potential environment for life.

Q: How does the EUROPA mission plan address planetary protection concerns?

The EUROPA mission plan includes sterilization procedures to prevent contamination of Europa's potentially habitable oceans with Earth organisms, ensuring the integrity of any potential alien life discovery.
