NASA has said it would like to send an astronaut to Mars some day soon, and 7-year-old Dexter Walters has volunteered.
In a letter to NASA, the young British boy wrote, "I heard that you are
sending two people to Mars and I would like to come, but I'm 7, so I
can't," Dexter's letter read. "I would like to come in the future. What
do I need to do to become an astronaut?"
