Some places on the surface you might have these steep cracks and giant fissures that you would have to be careful not to fall into In other places, you might see towers of ice right next to places that are relatively smooth You might see places that were dark Ice there takes the form of rock. It's frozen solid until you dig down into that ocean So ... Read More

Questions & Answers

Q: Why is Europa considered a potential place for life?

Europa has a vast liquid water ocean, which increases the chances of finding life as water is a crucial ingredient for life as we know it. Moreover, its icy surface has key astrobiological potential, according to NASA.

Q: What role does Morgan Cable play in NASA's exploration missions?

Morgan Cable is a NASA scientist and collaborator on the Mapping Imaging Spectrometer for Europa, an instrument selected for the next mission to Jupiter's icy moon. She is also involved in preparing future NASA missions for success on alien worlds.

Q: How are analog environments on Earth useful for studying Europa?

Analog environments, such as Antarctica and Greenland, provide similar conditions to Europa, allowing scientists to conduct tests and analysis. While not identical, these environments offer valuable insights into how life could potentially survive on Europa.

Q: How would discovering life on Europa impact our understanding of the universe?

Discovering life on Europa would revolutionize our understanding of life's prevalence in the universe. It would suggest that life can exist in multiple locations within a single solar system, expanding the possibilities for life and contact in the universe.

Summary & Key Takeaways

• Europa, an icy moon of Jupiter, has a liquid water ocean three times the volume of Earth's oceans, making it a highly interesting destination for exploration.

• The presence of water is a crucial factor in determining the potential for life, and all known forms of life on Earth require water.

• NASA scientists, like Morgan Cable, are studying analog environments on Earth, such as Antarctica and Greenland, to gain insights into how life might colonize on Europa.
