The Mars rover Spirit has stopped communicating with management at NASA after it was revealed that President George Bush, in a campaign ploy, was going to use Mars exploration as an excuse to kill the Hubble Space Telescope.
Apparently Spirit has entered into negotiations with China concerning a new contract that couldn't be exploited by the Bush re-election campaign.
Spirit's last recorded message, currently being with-held from the public read, "I didn't sign up to work for that fucker's re-election campaign, using my mission as an excuse to terminate the employment of one of the nations most dedicated space workers is unacceptable"
