NASA: The highest-resolution-yet temperature map and images of Saturn's icy moon Mimas obtained by NASA's Cassini spacecraft reveal surprising patterns on the surface of the small moon, including unexpected hot regions that resemble "Pac-Man" eating a dot, and striking bands of light and dark in crater walls.

The Cassini spacecraft's February 2010 encounter with Calypso yielded this incredibly detailed view of this Trojan moon. Irregularly shaped Calypso is one of two Trojan moons of the larger moon Tethys; Calypso trails Tethys in its orbit by 60 degrees. See Colorful Cratered Calypso to learn more about Calypso and its fellow Tethys Trojan, Telesto.

Space Exploration Technologies (SpaceX) announces the successful activation of its new Dragon spacecraft communication hardware aboard the International Space Station (ISS) during a series of operations conducted in January and March.

Appearing like eyes on a potato, craters cover the dimly lit surface of the moon Prometheus in this high-resolution image from the Cassini spacecraft's early 2010 flyby. The Jan. 27 encounter represented the closest imaging sequence yet of that moon for Cassini. This view looks toward the trailing hemisphere of Prometheus (86 kilometers, or 53 miles across). North on Prometheus is up and rotated 8 degrees to the right.

The NASA suborbital Terrier-Improved Malemute was successfully launched on March 27, 2010 at 10:09 a.m. Preliminary reports indicicate the payload performed well.
