Scientists thought Gale crater was an old lakebed, and it was specifically chosen as a landing site to allow Curiosity to collect samples from such a lakebed. But new research from scientists at the University of Hong Kong shows that most likely, the samples Curiosity has been analyzing during its sojourn didn’t actually form in a lake.

The researchers suggest that the samples Curiosity collected were deposited as part of dust storms over millions of years, covering up any existing lake sediment that might once have existed in Gale crater. The key to this assertion is hydrochemistry.
