Jupiter’s moon Europa has a salty ocean where life could exist, but in order to explore it, we need to drill through the moon’s thick ice shell. However, some scientists believe that the remains of marine life on Europa could be accessible on the surface for a lander to find. The icy surface of Europa is covered in cracks and fissures, and it might be possible that organisms are dragged to the surface as these features form. Experiments performed at NASA’s Jet Propulsion Labs even suggest that orbiters could investigate the infrared signature of Europa’s icy crust to look for tattered remnants of life.
