Mars Sample Return and the Mars 2020 Perseverance Rover

Our work at “Hogwallow Flats”, Jezero Crater, Mars was just mentioned in this Nature article. Check it out!

We collected three rock cores from the “Hogwallow Flats” area for return to Earth (pictures below). This area contains sedimentary rocks that were most likely altered by interactions with liquid water, which suggests habitable environments when they formed. The rocks we sampled contain significant amounts of clay minerals and sulfates, both which are materials associated with the preservation of biosignatures. They also represent the finest-grained rock samples collected by the mission so far. If there was ever life in Jezero Crater, its leftover residues (biosignatures) may be present in these samples. We will be working hard to get these samples back to Earth by the early 2030’s!
