Sample Science Input to Landing Site Selection for Mars 2020: An In-Situ Exploration and Sample Caching Rover

One of the Mars 2020 Rover mission's main objectives is to collect samples of martian material and seal them in individual tubes for possible return by a later mission[1]. In order for the M2020 rover to have the highest chances of making a significant discovery from the diverse kinds of geological targets that Mars offers, it is crucial to select a landing site that would put the rover in proximity to these features. The M2020 landing site selection process is open to all [2]; however at this meeting we are seeking input from the sample science community into attributes of the landing site that should be prioritized. This paper seeks to foster broader intellectual inputs from the community, and outputs from this discussion will be provided to the M2020 landing site selection committee.
