What they know, though, is that it is something we as humans have never seen before.
"Peering inside to look at something no one's ever seen. I've abraded a small patch of this rock to remove the surface layer and get a look underneath," the team responsible for the robot shared on Twitter.
"Zeroing in on my next target for #SamplingMars," the post added, adding photos of the planet.
There is another possibility here that could disappoint the scientists too. Since there is a lot of other white spots in the area, the piece in question might just be another random piece of the rock.
Either way, we can say that the discoveries caused a lot of excitement and hope in a general sense considering it is known that the Jezero hosted a lake approximately 3.700 billion years ago.
