GALE WINDS. Using TES data, a cross-section of Mars' atmosphere from the south pole (left) to the north pole (right) shows in the upper panel the warm atmosphere (red colors) in the south as southern summer begins. (It's still pretty chilly: 240 kelvins is -27 degrees Fahrenheit.) The lower panel shows a high-speed jet (red colors) has developed in the north at the same time. It has winds greater than 160 meters per second (365 miles per hour). Click on the image to download a larger version (1 MB). NASA/JPL/Arizona State University
