Why not just assume bad software and upload a new start? If that doens't work it's dead anyway.
I was listening to one of the team leaders describe his local tests involving an impossible scenario. He was testing an impossible scenario, just in case it magically became possible on Mars. Another example I linked involved shock testing a flight instrument when the test would prove nothing other than, yes, you can break this instrument if you shock it.
I just get the feeling again and again that NASA has some of the sharpest balloons in the world.
