Astronomy Picture of the Day - Valles Marineris: The Grand Canyon of Mars
NASA ^ | 10 Nov, 2024 | Image Credit: NASA, USGS, Viking Project

Explanation: The largest canyon in the Solar System cuts a wide swath across the face of Mars. Named Valles Marineris, the grand valley extends over 3,000 kilometers long, spans as much as 600 kilometers across, and delves as much as 8 kilometers deep. By comparison, the Earth's Grand Canyon in Arizona, USA is 800 kilometers long, 30 kilometers across, and 1.8 kilometers deep. The origin of the Valles Marineris remains unknown, although a leading hypothesis holds that it started as a crack billions of years ago as the planet cooled. Several geologic processes have been identified in the canyon. The featured mosaic was created from over 100 images of Mars taken by Viking Orbiters in the 1970s.

8 km deep? I wonder what the atmospheric density and temperature is at the bottom.

Doesn’t that look like something big skimmed across the surface at just the right tangent, only to be ejected into space again?

Agreed. I can’t even begin to comprehend the immensity of the forces involved in such an event.

Marsโ€™ geology is every bit as interesting as the Moonโ€™s. A lot happened there.

This was a failed project to build a planet sized Death Star weapon. The Empire started digging out the foundation but ran out of money due to the Galactic Senate over spending on other projects.

Ice is water.
