Changes in the texture of the Glen Torridon sediment analyzed with Curiosity indicate that at some point there was a change in how this sediment was deposited at the bottom of Gale Crater. This is understood to imply a change in the environment, from a deep lake to something else.
The papers have articles on these findings and more – although unfortunately the 51st Lunar and Planetary Science Conference, at which many were due to be presented later this month, was canceled due to COVID-19. However, we look forward to seeing the docs soon.
Right now, Curiosity is making an ambitious climb towards a formation on the lower slopes of Mount Sharpe called the Greenhue Gable. Hopefully this section can provide more information on the geological, geomorphological and climatic history of this region of Mars.
Until then, if you want to do your own exploration of Mars, go for the full resolution image.
