Mars Exploration Rover: Full-Scale Model

Full-scale model of the Mars Exploration Rover. The twin Mars Exploration Rovers Spirit and Opportunity were launched toward Mars in the summer of 2003. They arrived months later in spectacular fashion, bouncing down safely on the surface after a harrowing six-minute descent through the thin atmosphere. Spirit arrived on January 3, 2004, and Opportunity on January 24, 2004.
