These windstreaks are located in northern Terra Tyrrhena. The wind was blowing from NE to SW to create the streaks in the lee of the craters. This image is from NASA's Mars Odyssey.

The ejecta materials of this crater are more resistant to erosion than the surrounding materials. The wind has eroded pits and other features around the crater causing it to become a topographic high. This image is from NASA's Mars Odyssey.

What appear to be channels in this image from NASA's Mars Odyssey is the dissection of the higher elevations on the margin of Chryse Chaos. Continued dissection eventually creates the block/mesa forms termed chaos on Mars.

Diagnostic tests were run on the right-rear wheel and right-front wheel on NASA's Spirit. The right-rear wheel continued to show no motion in the latest tests and exhibited very high resistance in the motor winding.

This graph shows the atmospheric pressure at the surface of Mars, as measured by the Rover Environmental Monitoring Station on NASA's Curiosity rover. Pressure is a measure of the amount of air in the whole column of atmosphere sitting above the rover.
