Mars Dead or Alive: Mars Up Close

Since landing on Mars in January 2004, Spirit and Opportunity, the Mars Exploration Rovers, have helped scientists learn an amazing amount about the red planet. The sophisticated rovers far exceeded expectations with the geological clues they have dug up about the planet's past. In this video tour of the rover landing sites, the mission's principal science investigator, Steve Squyres, describes some of the discoveries made by the rovers, particularly unique rock textures and chemistries that suggest that they were formed in the presence of water.
