Enceladus has always been my #1 favoritist place to look for life. It’s not all that far away, and it seems to have a rather active geology:
Now, we get this:
Data from Cassini’s cosmic dust analyzer show the grains expelled from fissures, known as tiger stripes, are relatively small and predominantly low in salt far away from the moon. But closer to the moon’s surface, Cassini found that relatively large grains rich with sodium and potassium dominate the plumes. The salt-rich particles have an “ocean-like” composition and indicate that most, if not all, of the expelled ice and water vapor comes from the evaporation of liquid salt water.
That little moon just keeps getting cooler and cooler all the time. Wonder when Virgin Galactic will start taking vacation trips there?
