The Perseverance Rover Successfully Collects Rocks

The perseverance rover has successfully collected some rocks. They suggest that it's made of basalt, and might have been part of an ancient lava flow. The rock also has salts in it, which likely come from the rock interacting with water. And the presence of those salts means that there could have been ground water going through the sub surface of the planet - creating little pockets of habitable environments inside of that rock. Whether or not the rocks actually contain signs of life, that's going to take us a long time to find out. But for now, perseverance is going to collect some more rocks and pack it to them and sealed titanium tubes for future missions.
