According to the satellite agency, a boulder like that probably originated "in an ancient streambed or tiny pond."

it winds up through the foothills of the three-mile-tall Mount Sharp. In the end, some of these sediments were stacked.
The Peservance rover, Curiosity's robotic brother, is currently traversing the Jezero Crater on the planet, which NASA believes formerly held a lake and river delta.

The robot contains specialist technology designed to find prior signs of microbial life that may have maybe existed on a wetter, different Mars, even if the water is all gone now.
