Because we are primarily interested in biosignatures, we will focus on pp. 30-50 ("Objective B: Assess the Biosignature Potential Preservation Within the Selected Geological Environment and Search for Potential Biosignatures").
However, feel free to skim through other sections, such as the proposed payload on pp. 77-80.
To get a discussion started, please come with short answers to these 3 points about the papers:
(a) One thing you found cool.
(b) One thing you found dubious.
(c) One thing you did not quite understand.
