Your question was: As a computer scientist I'd like to know what processors, operating system and languages are use on the lander. The answer to your question is: Thanks for your interest in the mission and sorry for the delay in our response. We use a RAD6000 microprocessor, a version of the PowerPC chip once used on many Macintosh computers but enhanced to endure the Martian environment. It operates at three speeds, 5 million, 10 million or 20 million clock cycles per second. We have more than 74 megabytes of dynamic random access memory, plus flash memory. The language used is C, also C++ and Java for the testbed engineering. We appreciate your interest in the Phoenix Mars Mission!" So no Ada which surprises me a little. The OS is VxWorks as mentioned at http://blogs.windriver.com/deliman/2008/05/did-you-watch-i.html Chris M Moore
