‘Think Mars:’ Online petition urges manned mission CNN

A group of space enthusiasts are pushing ahead with a petition calling for a manned flight to the red planet, undaunted by the failure in recent months of two unmanned missions to Mars. The Mars Petition, which sets 2015 as a goal for humans to set foot on the planet nearest Earth, has received more than 10 thousand electronic signatures since Think Mars, the Mars Society and other space-related Web sites launched it earlier this month.
