The Cassini spacecraft took a daring plunge into the icy geysers of Saturn’s moon Enceladus last week in search of telltale signs of a habitable environment. The encounter with the mysterious plume lasted only tens of seconds as Cassini hurtled past at a speed of about 19,000 miles per hour, yet in these critical moments up to 10,000 particles per second were sampled and identified using the probe’s cosmic dust analyzer. Analysis of this data over the coming weeks could provide the most promising signs of habitability yet in the decade since Cassini’s initial flyby of the moon in 2005.
