2. Mars Mission

Audio for this story from Weekend Edition Sunday is not available.

Liane Hansen speaks with NPR's Joe Palca about this Friday's scheduled landing of the Pathfinder spacecraft on Mars, the first U.S. landing since 1976 when two Viking spacecraft touched down. Pathfinder is carrying a camera, weather equipment and a mini Martian dune buggy which will cruise around the landing site. One of the mission's goals will be to determine previous climate conditions by studying rocks on the planet's surface.
