<myValidation ⁄>Mars is a cold, dry, desert landscape of sand and rocks. Many land features on the present-day surface of Mars, such as volcanoes, canyons, and valleys, make it look very similar to Earth, but humans could not survive in the present environment on Mars. The average surface temperature is -63 degrees C (-81 degrees F), and nighttime temperatures on Mars can plunge to -110 degrees C (-170 degrees F). By comparison, the lowest temperature ever recorded on Earth was -89 degrees C (-130 degrees F) at Vostok, Antarctica in July, 1983.
