One of the most valuable scientific tools around is in danger during the upcoming Martian winter. Spirit seems to be permanently stuck in her current spot, which will make it much harder for her to get the power necessary to survive the winter. The Mars rovers are one of NASA's great success stories. Hopefully the plucky little robot will surprise us yet again.
Of all tyrannies, a tyranny sincerely exercised for the good of its victims may be the most oppressive. It would be better to live under robber barons than under omnipotent moral busybodies. The robber baron's cruelty may sometimes sleep, his cupidity may at some point be satiated; but those who torment us for our own good will torment us without end for they do so with the approval of their own conscience.
