The young and young at heart can take part in Mars exploration, whether by naming two red planet rovers or sending their names along with them. The Planetary Society and NASA have teamed up to sponsor a contest for students to name two rovers expected to launch in the summer of 2003. The competition is open to children between the ages of 5 and 18 in kindergarten to the 12th grade in U.S. schools. The deadline for submissions is January 31, 2003.
