Mars has a massive river, reveal 3D pictures

Jan 21 (): New astonishing images by ESA, the European Space Agency have revealed a 1,500 km long and 7 km wide river that once ran across Mars. The agency’s Mars Express has taken images of the upper part of the remnants of Reull Vallis river on Mars using a high-stereo camera, which gave an impressive look at the landscape.

The latest 3D images clearly showcase the beautiful landscape of the large area of the Reull Vallis that is perfectly complete with one tributary and mountains off to the right. At a particular point, Reull Vallis is 300 metres deep and nearly seven kms wide.

It is believed, Reull Vallis has formed in the distant Martian past when running water flowed, creating a channel through Promethei Terra Highlands before running on towards the floor of the vast Hellas basin.

This structure is bordered by numerous tributaries, one of the tributary cutting into the main valley towards the upper (north) side is clearly visible. The pictures show only one river but with multiple tributaries, all of them meeting with the same.

The images also show circular step-like structures on the inner walls of the sediment-filled crater in the foreground of the second perspective view.

The sides of Reull Vallis are steep and sharp. These structures are believed to be caused by the passage of loose debris and ice during the “Amazonian” period – which continue to this day – due to glacial flow along the channel.

The structures were formed long after it was originally carved by liquid water during the Hesperian period, which is believed to have ended between 3.5 billion and 1.8 billion years ago.

Experts say the pictures show ‘striking resemblance to the morphology found in regions on Earth affected by glaciation’.

Currently, NASA’s Curiosity Rover is investigating Mars for evidence of water, and is actually going to perform some tests soon.
