Will it hold up in the cold? What about rover material properties at those temperatures? Iron becomes brittle at below zero. Do other materials have strange, unexpected properties?
“Do other materials have strange, unexpected properties?”
Strange, yes. Unexpected, no. We have refrigerators that can gets super cold. They have studied this stuff. Will it fail? Maybe. But this is not the first device to need to survive extreme cold.
Yes, it will hold up in the cold. This is not NASA’s first rodeo.
