THE MARS MISSIONS MARS PATHFINDER – JULY 1997 MARS GLOBAL SURVEYOR - 1996 MARS ODYSSEY PROBE – OCT 2001 SPIRIT ROVER – Jan 2004
SOJOURNER ROVER • This probe found evidence of water and HAEMETITE: a rock only found in or near water. • Both Sojourner Rover and Opportunity Rover are still working on Mars!
