Be sure to add me to your favorites list Hot Wheels Mars Pathfinder Sojourner Rover JPL NASA This is a never played with, only stored condition, small version of the Sojourner Rover, which was deployed from the Mars Pathfinder spacecraft back in 1997. It's made of die cast metal, with plastic and rubber trim, and is a 2 inches long. This rover explored Mars starting July 4th 1997, and was a great success. The antenna pops up and down and the suspension really works! The wheels are rubber and roll as well. This is a really nice mini version of this incredible machine!
