The best global image of all Mars was made by stitching together nearly 21,000 Mars photos, each showing details as small as 100 meters (330 feet) wide. Use your browser to zoom into the image and pan across it, exploring craters, volcanos, lava flows, and water-carved channels.

Google Mars lets you scan, pan, and zoom across Mars just as its big-brother site, Google Earth, lets you explore our home planet. Learn more about how it was made.
