NASA’s probe on Mars captured stunning new images of the largest valley in our solar system, a system of huge canyons that spread 2,500 miles along the equator of the Red Planet. About ten times the length of the Grand Canyon on Earth, it is three times deeper than it.
The University of Arizona researchers wanted to explore it further, so they used a high-resolution camera called HiRISE, found on NASA’s Mars Reconnaissance Orbiter.
And they’ve taken pictures of the valley since 2006 to try to get a look at its strange features and to get insight into how it formed.
The Grand Canyon Earth System is said to have formed over billions of years of moving fast-moving water.
On the other hand, the formation of Valles Marineris may be due to a huge amount of volcanic activity.
One theory is that the crust of Mars may have expanded and opened up when a large group of volcanoes were first forming.
Old rivers, landslides and magma may have caused further erosion.
