It wasn't that long ago that humans had no idea what it was like on the surface of Mars. Skywatchers have known for millennia — at least — that the tiny orange dot moves across the night sky in huge loops that look like illegible cursive writing.
— now more than 500 Martian days, which are called"sols" — exploring a corner of the famous Jezero Crater. Scientists think the low-lying plain was once a river delta submerged in fresh water. More than 3.5 billion years ago, river channels spilled over the crater wall and created a lake. Scientists see evidence that water carried clay minerals from the surrounding area into the crater lake,". It's possible that microbes once lived in the region.
The spectacular image that Byrne shared shows layers of sedimentary rock visible from Perserverence's vantage point in the Jezero crater. The image isn't just a stunning insight into the Martian landscape. It also contains valuable information for geologists who can draw surprisingly specific conclusions by measuring the depth of the photos' layers and analyzing the appearance of the rock itself.
