Abstract: The Mars 2020 mission will seek the signs of ancient life on Mars and will identify, prepare, document, and cache a set of samples for possible return to Earth by a follow-on mission. Mars 2020 and its Perseverance rover thus link and further two long-held goals inThe Mars 2020 Mission Edited by Kenneth A

“…One of the highest priorities SKG is to validate atmospheric models by taking advantage of the unprecedented set of meteorological quantities that will be measured by this mission [Rodriguez-Manfredi et al 2020;companion paper in this Special Issue]. This SKG corresponds to objective D2 of the mission [Farley et al 2020;companion paper in this Special Issue], and this work will help to address it. The meteorological environment provides fundamental constraints relevant for life and habitability, the radiation conditions, soil and air temperature, and water vapor abundance that directly influence habitability.…”

“…ACI will enable three primary tasks: (1) determine the best focus position for the spectrometer, (2) correlate the laser position with the target surface to provide morphological context of SHERLOC spectra and chemical maps, and (3) place the high resolution chemical maps in context with the rest of the target. In addition, the ground-based data processing pipeline also uses the imaging (Farley et al 2020) are mapped into SHERLOC contributions and data products addressed by the SHERLOC investigation data to correct for arm drift during prolonged measurements. The resulting imaging system also provides additional science capabilities such as range-finding with ∼0.2 mm accuracy from a safe standoff from the surface, 10.1 µm/pixel views of rock and regolith texture and structure, ability to generate of 3D surface relief maps via MAHLI heritage Z-stacks.…”

“…The Mars 2020 mission will make Fig. 61 Overview of SHERLOC operations staffing including tactical roles scientific measurements to better understand the history of the sites we are investigating and to determine which core samples should be extracted and cached for eventual return to Earth Farley et al 2020). This process requires both strategic planning over large scale regions of interest (hundreds of square meters) and tactical decisions that need to be planned every sol of operation for the robotic arm workspace directly in front of the rover.…”

“…Perseverance will perform scientific research that explores an astrobiologically relevant ancient environment on Mars within the Jezero Crater landing site. 1 The scientific goals of the mission are to (i) explore an astrobiologically relevant ancient environment on Mars to decipher its geological processes and history, including the assessment of past habitability, (ii) assess the biosignature preservation potential and search for potential biosignatures, and (iii) demonstrate significant technical progress towards the future return of well-documented samples to Earth, selected for their scientific value. Scanning habitable environments with Raman and luminescence for organics and chemicals (SHERLOC) is one of seven selected instruments as part of the Mars 2020 scientific payload.…”
