Ever dream of walking on Mars? Well, that probably won't happen, but thanks to NASA, you can explore it from your phone or desktop.
The agency recently released "Mars Trek," a Google Earth-like experience that lets users click around the surface of the Red Planet.
It even features a zoom function that provides detailed views of landmarks like Olympus Mons, which, at 379 miles in diameter, is the largest volcano in the solar system. There is also a 3-D view that allows users to rotate the planet around and take a look at its poles.
A few other cool features: the ability to see the positions of various Mars orbiters, a drawing tool to plot future Mars road trips, and data overlays, in case you were wondering what the planet looks like through the eyes of a thermal emission spectrometer.
