From the Wikipedia page, the RAD6000 was used in the Mars Rovers. I believe that the Mars Rovers used Java, partly because of static analysis that can be performed on source and object code and partly due to the garbage collection.

I would be shocked if the actual rovers used Java. Perhaps Java is used in the tools used to control them (that send the signals), but not the little guys themselves.

Yep:

"The places where NASA scientists have used Java for this mission is all on the ground side right now."
