What a Geologist Sees When They Look at Perseverance’s Landing Site Posted on What a Geologist Sees When They Look at Perseverance’s Landing Site Geologists love fieldwork. They love getting their specialized hammers and chisels into seams in the rock, exposing unweathered surfaces and teasing out the rock’s secrets. Mars would be the ultimate field trip for many of them, but sadly, that’s not possible. Instead, we’ve sent the Perseverance rover on the field trip. But if a geologist were along for the ride, what would it look like to them? Geologists tell us there’s no substitute for fieldwork. Jezero Crater is where Perseverance is going on its field trip, and fortunately, the crater has been examined in different ways by different satellites. To a geologist’s eyes, the crater is a bonanza.
