In this case, we are talking about Martian days — sols, which last longer than terrestrial ones. On October 17, the rover received the 39th sample of Martian rock soil from the Sequoia rock, which will give even more information about the formation of the climate and the history of life on the Red Planet. The fact is that this region is enriched with sulfates and indirectly indicates that there was salt water here. On October 21 and 26, with the help of Navcams, Curiosity took a panoramic picture of the surface, where the sample was taken.

"The types of sulfate and carbonate minerals that Curiosity's instruments identified last year help us understand what Mars used to be like. We've been expecting these results for decades, and now Sequoia will tell us even more," comments Ashwin Vasavada, Curiosity project scientist at NASA's Southern California Laboratory.
Recall that Curiosity has been on Mars for more than 11 years. It was launched on November 26, 2011, and descended to the surface of the planet on August 6, 2012.
