Mars 2020 Project Landing Site Assessments and Selection Process
Explore the detailed process of assessing and selecting landing sites for the Mars 2020 Project by the Jet Propulsion Laboratory, California Institute of Technology. The assessment progress, site selection considerations, and landing site selection schedule are meticulously outlined to ensure optimal surface productivity, safety, and scientific value. Dive into the pre-decisional planning and discussion stages as the project aims to identify the most suitable locations on Mars for exploration.

Jet Propulsion Laboratory California Institute of Technology Mars 2020 Project Landing Site Engineering Assessments Mars 2020 Landing Site Workshop #2 Mars 2020 Project August 4-6, 2015 Pre-decisional: For Planning and Discussion Purposes Only
Site Selection Considerations Jet Propulsion Laboratory California Institute of Technology Mars 2020 Project Science Value Surface Productivity Required traverse distances and traversability Thermal/energy impacts Instrument considerations Landing Safety EDL system margins Terrain induced failure rates Site Selection Planetary Protection Special regions Subsurface water Program Considerations SRL constraints Pre-Decisional: For Planning and Discussion Purposes Only 2
Assessment Progress Since LSW #1 Jet Propulsion Laboratory California Institute of Technology Mars 2020 Project Because of limited throughput, we focused on the top 9 ranked sites from the 1st workshop Completed first pass landing safety assessments Built and used site-specific atmosphere and terrain products Quantified impact of TRN Completed first pass surface scenario assessments Gathered ROI information (location and prioritization) and estimated required traverse distances Quantified thermal/energy impact of site latitude Identified instrument considerations Identified landing site planetary protection constraints Assessed program landing site selection implications Pre-Decisional: For Planning and Discussion Purposes Only 3
Landing Site Selection Schedule Jet Propulsion Laboratory California Institute of Technology Mars 2020 Project 1st Workshop May 2015 27 sites, ranked by science merit Allows assessment of need for EDL and/or surface operability enhancements Allow early characterization of candidate sites 3rd Workshop January 2017 Mature EDL and surface assessments Down-select to ~4 sites 4th Workshop/Site Selection June/July 2018 L-2 years 1 site (+ backup) Full EDL safety and surface productivity assessments 2nd Workshop Initial EDL and surface assessments for top sites Supports TRN decision by PDR Down-select to ~8 sites Pre-Decisional: For Planning and Discussion Purposes Only 4
Summary Jet Propulsion Laboratory California Institute of Technology Mars 2020 Project The next set of presentations go through the engineering assessments and results at a high level The goal is to inform the community of the non-science site selection considerations in play Last opportunity to inform the TRN decision For throughput reasons, work to date has focused on the top 9 sites The results are preliminary, but much more mature than they were on MSL at the PDR timeframe Pre-Decisional: For Planning and Discussion Purposes Only 5
