NASA Mars24 \"sunclock\"
NASA's that "purports to be derived from the application used in mission control. It's the only app I know that depends on the new Java3D frameworks, and may be the reason why they were released by Apple." [updated with Maestro info]
Meanwhile readers note that the Mars Rover uses a variation of PowerPC chips: "The computer in each Mars Exploration Rover runs with a 32-bit Rad 6000 microprocessor, a radiation-hardened version of the PowerPC chip used in some models of Macintosh computers, operating at a speed of 20 million instructions per second."
