Curiosity is about the size of a small SUV — 10 feet long, 9 feet wide and 7 feet tall.

It has a suite of instruments:

  • The Mars Hand Lens Imager (for close-up pictures) and a Mast Camera (to take photos of the surroundings)
  • An instrument named ChemCam to vapourise thin layers of Martian rocks.
  • Radiation Assessment Detector to study the radiation environment at the surface of Mars
  • Rover Environmental Monitoring Station to measure atmospheric pressure, temperature, humidity, winds, plus ultraviolet radiation levels
  • Dynamic Albedo of Neutrons instrument to measure subsurface hydrogen

The main mission of Curiosity was "to search areas of Mars for past or present conditions favorable for life, and conditions capable of preserving a record of life."
