Guide Note: NASA's "Mars Reconnaissance Orbiter", a robotic satellite armed with a digital camera, snapped the first recorded images of an avalanche on the planet Mars. The photograph looks down on a mountainous region of the red planet, depicting a 700-meter-high icy cliff and a giant, red dust cloud falling toward to the planet's surface. The avalance was caused by the warming climate in the Northern Hemisphere of Mars, which causes carbon dioxide ice to vaporize and release rock and other particles.
