Taking Mars' Temperature

This graph shows the rise and fall of air and ground temperatures on Mars obtained by NASA's Curiosity rover. The data cover Aug. 16 to Aug. 17 and were taken by the Rover Environmental Monitoring Station. Ground temperatures vary from as high as 37 degrees Fahrenheit (3 degrees Celsius) to as low as minus 131.8 degrees Fahrenheit (minus 91 degrees Celsius), showing large temperature oscillations from day to night. Air temperatures vary from as high as 28 degrees Fahrenheit (minus 2 degrees Celsius) to as low as minus 103 degrees Fahrenheit (minus 75 degrees Celsius), indicating, as expected, variations in air temperatures are less extreme than ground temperature variations.
