Virtual Mars

Explore Mars with a click of your mouse! Click on the image of Mars, and it will be redrawn with the selected point at the center of the view. Click on the button beneath the image to toggle the names of surface features and landing sites on and off.

Night and day areas will be recalculated every five minutes to keep up with the planet's rotation.


The longitude calculation of the sunlight angle is based in part on a formula derived by Jim Scarborough. Visit his Mars Pathfinder Clock for more information.

The image of the Martian surface was developed from a mosaic of images transmitted by the two Viking orbiters. This mosaic, along with the original images, can be found at the MSSS Viking Image Archive.

Information on names and locations of surface features and landing sites was found at the PDS Mars Explorer for the Armchair Astronaut.
