(PhysOrg.com) -- NASA's Cassini spacecraft has successfully completed its second-closest encounter with Saturn's icy moon Helene, beaming down raw images of the small moon. At closest approach, on June 18, Cassini flew within 4,330 miles (6,968 kilometers) of Helene's surface. It was the second closest approach to Helene of the entire mission.

Cassini passed from Helene's night side to the moon's sunlit side. It also captured images of the Saturn-facing side of the moon in sunlight, a region that was only illuminated by sunlight reflected off the last time Cassini was close, in March 2010. This will enable scientists to finish creating a global map of Helene, so they can better understand the history of impacts to the moon and gully-like features seen on previous flybys.

The closest Helene encounter of the mission took place on March 10, 2010, when Cassini flew within 1,131 miles (1,820 kilometers) of the moon.

"Cassini captures ice queen Helene". Helene is reported to have told Cassini that she would never no matter the situation. Sorry, please forgive the joke, I couldn't resist.
