Mars's atmosphere is about 100 times thinner than Earth's. Without a thermal blanket, Mars can't retain any heat energy. On average, the temperature on Mars is about minus 80 degrees F (minus 60 degrees C). In winter, near the poles temperatures can get down to minus 195 degrees F (minus 125 degrees C).A summer day on Mars may get up to 70 degrees F (20 degrees C) near the equator, but at night the temperature can plummet to about minus 100 degrees F (minus 73 C). summer day on Mars may get up to 70 degrees F (20 degrees C) near the equator, but at night the temperature can plummet to about minus 100 degrees F (minus 73 C).
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.
