This past week on Mars, Perseverance made a pit stop near Overlook Mountain to abrade a rock called Old Faithful Geyser. This target is situated within the Western side of the Margin Unit, an area around the upper edge of Jezero Crater that is astrobiologically interesting due to its abundant carbonate.
The recent acquisition of Perseverance’s 21st core sample, Comet Geyser, from Bunsen Peak reveals significant geological interest due to its composition of carbonate and silica key minerals for preserving biosignatures. After investigating the high-standing bedrock at the Bunsen Peak workspace de
