Dear Colleague:

The program for the second landing site workshop for the 2020 Mars Rover mission is now posted. If you are listed as a speaker for a presentation at the workshop. Please review the program carefully to ensure you are able to attend and participate at the time indicated. It is your responsibility to inform your co-authors about your presentation.

The second landing site workshop for the 2020 Mars Rover mission will be held at the Doubletree Hotel, Arcadia, CA, on August 4-6, 2015 (next week!). Workshop logistics can be found at:

The primary goal of the second workshop will be to evaluate the ~30 candidate landing sites that emerged from the first workshop as well as new candidate sites and narrow the list remaining under consideration to ~8.

The science potential of candidate sites should be described using defined and ranked Regions of Interest (ROIs) in and near the landing site that describe science targets for exploration by the rover. Presenters at the workshop must make a comprehensive, persuasive talk on why a site is the right one for the 2020 mission and payload, including how the science objectives of the mission can be accomplished and (where possible) an assessment of how the surface characteristics meet the engineering criteria so that each site can be comprehensively and fairly assessed.

The 2020 project science group has adopted a set of science criteria for the 2020 landing site that should be considered in developing the science potential of candidate sites. This rubric and the scientific selection criteria that will be used to evaluate the candidate sites is posted at: Proposers are required to evaluate their site relative to the rubric and scientific selection criteria as a part of their presentation: the criteria will be used at the workshop to summarize the relative science merits of the candidate sites for ranking.

Thank you for your interest in landing site activities related to the Mars 2020 rover mission. We look forward to seeing you at the workshop next week!
