This Martian Basin Shows Off Our Solar System’s Violent Past

An impact 4.1 billion years ago left quite a mark! A Mars Express photo from late 2013 shows craters in Hellas Basin on Mars, which was formed when the planets in our young Solar System were under intense bombardment

Did that impact 4.1 billion years ago ever leave a scar! Here, a Mars Express photo from late 2013 (and just highlighted now) shows off craters in Hellas Basin, which was formed when the planets in our young Solar System were under intense bombardment from leftover remnants.
But over time, wind and erosion on Mars have changed the nature of this basin, the German Space Agency explained.
“Over time, the interior of Hellas Planitia has been greatly altered by geological processes,” the German Space Agency stated.
“The wind has blown dust into the basin, glaciers and streams have transported and deposited sediment, and volcanoes have built up layers of low-viscosity lava on the floor of Hellas. Despite its exposure to erosion and coverage by deposits for a long period of time, it is the best-preserved large impact basin on Mars.”
