At the moment within the historical past of astronomy, we get our first close-up have a look at potato-shaped Hyperion.

Resembling a lumpy chunk of coral floating by means of area, Hyperion is likely one of the weirdest moons not simply of Saturn, however in the entire photo voltaic system. Its form is irregular, its rotation is chaotic, and it appears oddly spongelike. On Sept. 26, 2005, Cassini accomplished its first flyby of this weird moon, giving NASA each true- and false-color views of its floor. Cassini additionally measured a powerful electrostatic cost on Hyperion’s floor, the primary on any area object apart from Earth’s Moon: A stream of electrons from Hyperion washed over Cassini, giving it the equal of a 200-volt shock from 1,200 miles (2,000 kilometers) away. The cost was sudden, as Hyperion was regarded as inactive, and highlighted potential risks for each robotic and human area explorers on future visits to airless planetary objects.
