14 DAY TRIAL // It will be some time before ordinary folks can pack their tents and set out to explore Mars by foot. Until then, space enthusiasts have to make do with whatever pictures and videos scientists decide to share with the public.
The video above is a simulated fly-through that lets people explore Mars' largest canyon, Valles Marineris.
Scientists say that this canyon also happens to be the largest in our solar system. Thus, it is approximately 2,500 miles (4,023 kilometers) long and 125 miles (201 kilometers) wide.
Just don't let the Grand Canyon hear this. Odds are it'll turn green with envy.
The video documents just a small section of the Valles Marineris, i.e. a 5-mile-deep (8 kilometers) valley named Hebes Chasma.
This valley sits close to Mars' volcanic Tharsis region, and some suspect that it formed when giant volcanoes in this part of the planet went haywire.
