[Geoldept] big news from Mars

[Melissa Rice]

Hi all,

I want to share some news from the Perseverance mission, which was just announced yesterday: we've collected a sample of a mudstone that is a potential biosignature (emphasis on potential - but it's a fascinating rock either way!). In my opinion, this is the most significant discovery of the mission thus far.

More in this NY Times story: https://www.nytimes.com/2024/07/25/science/nasa-perseverance-rover-mars-rock.html

Hope everyone is enjoying an invigorating summer!

Melissa
