NASA's Cassini spacecraft has made its deepest dive yet through the plume emanating from the south pole of Saturn's icy moon Enceladus.
Cassini flew low through the plume today (Oct. 28) at about 11:22 a.m. EDT (1522 GMT), zooming within a mere 30 miles (50 kilometers) of Enceladus' frigid surface. During the encounter, the spacecraft snapped photos and gathered samples that should help researchers learn more about the moon's life-hosting potential. (An ocean of liquid water sloshes beneath Enceladus' icy shell, and the plume material comes from this subsurface sea.)
Cassini checked in with its handlers a few hours after the encounter, providing a general status and health update. The first flyby photos won't be released until Thursday night (Oct. 29) or Friday (Oct. 30) at the earliest, while initial analyses of plume particles will likely take a week or so, mission team members have said. So keep checking back with Space.com to see what the close encounter — the 21st Enceladus flyby Cassini has performed since arriving in the Saturn system in 2004 — ends up revealing.
