Mimas has drawn a fair amount of attention with its “Death Star”-like appearance, but with new images from the Cassini spacecraft, this icy moon of Saturn has just gotten a lot more interesting. The highest-resolution-yet temperature map and images of Mimas reveal surprising patterns on the surface of the small moon, including unexpected hot regions that resemble “Pac-Man” eating the Death Star crater (officially known as Herschel Crater), as well as striking bands of light and dark in crater walls.
“After much deliberation, we have concluded: Mimas is NOT boring,” said Carolyn Porco, Cassini imaging team leader, in an e-mail about the new images. “Who knew?!” And best of all, Porco added, “be sure you have a pair of red/green glasses handy ’cause you won’t want to miss peering into gigantic Herschel crater in 3D!”
Cassini collected the data on Feb. 13, and Porco said the team has spent some quality time poring over the images.
