Five Things About NASA's Mars Curiosity Rover


  • How Big Is It?: At 2.8 meters long, the Mini Cooper-sized rover is much bigger than its rover predecessors, Spirit, Opportunity and Sojourner.
  • Landing: Where and How: Curiosity will land near the foot of a mountain taller than Pike's Peak near the middle of Gale Crater, which is the size of Connecticut and Rhode Island combined.
  • Toolkit: Curiosity will use 10 science instruments to examine rocks, soil and the atmosphere.
  • Big Wheels: Each of Curiosity's six wheels has an independent drive motor. The two front and two rear wheels also have individual steering motors. The wheels' diameter is double the wheel diameter on Spirit and Opportunity, which will help Curiosity roll over obstacles up to 75 centimeters high.
  • Rover Power: A nuclear battery will enable Curiosity to operate year-round and farther from the equator than would be possible with only solar power.
