Earlier this year, Mars One announced plans to send four people to the Red Planet by 2023, where they will be stars of a reality show, of course. If you pooh-poohed the gambit as totally unfeasible, you'd be wrong in at least one way—the group has no shortage of people willing to get in front of the camera. It reports that more than 1,000 people have volunteered to make the one-way trip via emails to the Mars One website. The group says it will begin the selection process next year, reports Yahoo. In addition to the four pioneers, it wants to send an additional four people to the planet every two years, until a colony of 20 is established. (More Mars stories.)
