Rad-hardened PowerPC chip. Probably a fairly old model by today's
standards, as NASA mostly uses tried-and-tested designs. Apparently
the same computer has been used with very few changes for a number of
other space missions. The system runs under the Wind River VxWorks
operating system (a popular and widely used RTOS).
