One of the Most Stunning Mars Videos You've Ever Seen

Have you ever dreamed about flying high above an alien planet? European Space Agency has just presented this hypnotic video, which gives us a look from the viewpoint of the ESA's imaging and mapping satellite, the Mars Express, when it flies above our planetary neighbour's largest canyon, the largest in the entire Solar System.


One rarely has seen such stunning, not of this Earth videos — for my money, only the footage of the Huygens probe landing on Titan, and the landing of Curiosity was this impressing. The footage was created and processed from images taken by the High Resolution Stereo Camera on Mars Express. ESA explains what we're seeing here:

Glide through part of the largest canyon on Mars, Valles Marineris, in this stunning colour movie from ESA’s Mars Express. Valles Marineris is not just the largest canyon on Mars, but at 4000 km long, 200 km wide and 10 km deep it is the largest in the entire Solar System. The movie focuses on an enclosed 8 km-deep trough in the northern most part of Valles Marineris, called Hebes Chasma.

The movie glides over impact craters pockmarking the plains separating the troughs, down cliff faces scarred by landslides, and along the rough valley floor. In some parts of the valley Mars Express has detected water-bearing minerals, suggesting that significant quantities of water may have once flowed here.

The formation of Hebes Chasma is likely connected to the nearby volcanic Tharsis region, home to the planet’s vast Olympus Mons volcano. During periods of intense volcanism the whole region stretched upwards, causing tremendous stress in the crust further way. Unable to withstand the strain, the crust ripped open, collapsing into the chasms found in and around Valles Marineris.

This is remarkable!

But a sense of scale would be nice. I know Valles Marineris is g i g a n t i c being bigger than the entirety of North America and so it follows tht Hebe Chasma is still pretty damn huge.

But how huge? I'd like to seem some comparison of things I do know the size of.
