Curiosity Rover

Recently the Mars Science Laboratory rover, Curiosity, has been in a space-simulation chamber at NASA's Jet Propulsion Laboratory. Tests inside the 25-foot-diameter chamber (7.6-meters) put the rover through various sequences in environmental conditions resembling Martian surface conditions. After the chamber's large door was sealed, air was pumped out to near-vacuum pressure, liquid nitrogen in the walls dropped the temperature to minus 130 degrees Celsius (minus 202 degrees Fahrenheit), and a bank of powerful lamps simulated the intensity of sunshine on Mars.
