Ion Drive in operation

Apparently NASA’s Deep Space 1 probe has just been officially decommissioned, slightly over two years after its planned End of Mission date. What caught my eye on this was that DS1 was the first experimental spacecraft to test an Ion Engine — a technology developed in the 1960’s, and for many people, first mentioned on TV’s Star Trek. Apparently the little craft did pretty well for itself. About time NASA had a success!
