Helene is one of the Trojan moons of Saturn. The Cassini robotic explorer recently captured this image of it (as always, click to enlarge). APOD has it in the form of a 3-D (anaglyph) image.
Seven years into its mission, Cassini is still going strong – a wonderful example of what NASA could be doing instead of wasting money on purposeless manned space flight...
Wasn't Cassini the one that had the plutonium power source that everyone was freaked out about before it launched?ReplyDelete
Yup, that's the one. NASA has been reluctant to try a nuclear powered spacecraft ever since...ReplyDelete
