Pathfinder landed on the surface of Mars in 1997. The craft, launched on December 5, 1996, traveled for 211 days and 309 million miles to reach the surface of Mars. A small rover named Sojourner (named after Sojourner Truth) traveled about the surface and analyzed rocks and the surface of the planet. The two vehicles (both significantly outliving scientific estimates) sent back 2.3 billion bits of data before transmissions stopped on September 27, 1997. Children can view some of the images of Mars at: Pathfinder.

Artist’s Conception of Phoenix on Surface of Mars

Phoenix was launched by NASA in 2007. The spacecraft landed on a polar region of Mars on May 25, 2008, and conducted tests on water and surface chemistry until November 2, 2008. Then the Martian winter set in, and the fragile equipment could no longer send data.  Children could learn more at: http://phoenix.lpl.arizona.edu/kids.php.
