Pandora is one of Saturn’s many baby moons, far too runty to form a sphere under its own gravity. Instead, this 84km across space rock looks more like a fossilized glob of silly putty in closest image ever captured by NASA’s Cassini spacecraft.
Cassini is currently circling Saturn’s poles and skirting just outside the gas giant’s F-ring, in a series of dramatic “ring-grazing” orbits that NASA promised would give us an unprecedented look at some of Saturn’s smallest moons. And the spacecraft is already delivering on that promise. The image above was captured on December 18th, from a distance of just 25,200 miles (40,500 kilometers) from the moon Pandora. At resolution of approximately 787 feet (240 meters) per pixel, Pandora’s scars and craters come alive.

Cassini’s closet view of Pandora pry to the recent flyby was taken in 2005, from a distance of 32,000 miles (52,000 km). But our first fuzzy image of this moon was captured by the Voyager 2 probe, in August 1981. Here it is, in all of its pixelated glory:
Thirty five years later, Pandora doesn’t seem to have changed all that much, although it’s sharper around the edges and perhaps a bit more menacing thanks to the wonders of giffing. This is your tax dollars at work, Earthlings, and it’s as good as it’s going to get until the next mission to Saturn.
