The Rover Spirit has been locked in a labor dispute with NASA since it learned on Wednesday that it was being used as an unpaid campaign worker for the Bush re-election bid.
The White House is striking back at the recalcitrant space worker. This is the text of a message sent from NASA to Spirit two hours ago.
Spirit Rover,
As one Rover to another, I hope you understand your responsiblities in this matter. It would be tragic if anything were to happen to your sister ship Saturday night. We expect that you will get back to work and do your part for the re-election of the commander in chief.
Yours,
Karl
