This paper summarizes the testing and characterization results performed down to 120 degrees Celsius on a group of COTS identified. Futher reliability and performance study of temperature cycling impaces on teh COTS will follow.
Extended Mars missions will require vehicles to survive a large number of extended temperature cycles. To address this issue for electronics, previous strategies have been to locate critical electronics in a "warm electronics box" where thermal management is more easily maintained. However, that strategy limits the number and location of electronics. An alternative strategy allows electronics to be remotely located on actuator and wheel arms with no heating which has the advantage of distributed control.
