Home This illustration depicts a lake of water partially filling Mars’ Gale Crater. It would have been filled by runoff from snow melting on the crater’s northern rim. Evidence of ancient streams, deltas, and lakes that NASA’s Curiosity rover has found in the patterns of sedimentary deposits in Gale suggests the crater held a lake like this one more than three billion years ago, filling and drying in multiple cycles over tens of millions of years.

Filled with briny lakes, the Quisquiro salt flat in South America’s Altiplano represents the kind of landscape that scientists think may have existed in Gale Crater on Mars. (Maksym Bocharov)
This graphic depicts paths by which carbon has been exchanged among Martian interior, surface rocks, polar caps, waters and atmosphere, and it also depicts a mechanism by which it is lost from the atmosphere. (Lance Hayashida/Caltech)
