    Sunday, July 23, 2017, 1:30 pm to 5:00 pm in the New Mexico Room at the La Fonda Hotel, Santa Fe, NM

The Mars 2020 rover mission is the first stage in Mars Sample Return. The Returned Sample Science Board (RSSB) of the Mars 2020 project is pleased to host this half-day workshop specifically to familiarize the sample analysis community with the objectives of the mission and the kinds of samples that are needed to address them. The architecture of the project will be reviewed, an overview of the downselected landing sites will be provided, and the sample collection process will be described. Results of the RSSB’s analysis of the priority investigations, measurements, and samples required to achieve the Mars 2020 objectives will be presented for discussion by the community.  Ample time for discussion will be provided.    

Martian Meteorites Under the Microscope 
A Post-Meeting Workshop
Led by Dr. Anthony Irving
Saturday, July 29, 2017 at the University of New Mexico, Albuquerque, NM

This one-day interactive workshop will provide an opportunity to examine many different types of Martian meteorite specimens using petrographic microscopes, and also to permit discussion of aspects of their chemistry, age, shock features, nomenclature and other relevant topics.  Now that the number of unpaired Martian meteorite specimens exceeds 100, it may be an ideal time to assess the state of our collective understanding of these intriguing rocks, which still represent the only actual samples from Mars available for scientific study.  Since few people have had the opportunity to closely examine these specimens for themselves, a major goal of this workshop is to permit enthusiasts (even those with limited petrologic expertise) to indulge in both their aesthetic and scientific attributes.  Additional sessions will involve experts making short (~25 minute) tutorial presentations on other topics, followed by ample time for interactive discussion and contributions from attendees.

Cost: $US 40 (includes transportation to and from Albuquerque, NM)
