Dear mineral sciences community members, The first annual MSA Tucson Meeting, which took place in February 2026, was a great success, with ~150 submitted abstracts and 200 attendees, including ~50 students. We heard from many of you who attended that it was the best scientific meeting you had been to in a long time – or ever. Encouraged by that enthusiasm, we are planning the 2027 MSA Tucson Meeting to be just as great or even better. The meeting will start on Sunday, February 14, with a day of overlap with the Tucson Gem & Mineral Show, followed by 3 days of talks + posters and other events (February 15-17), and an optional day of field trips (Thursday February 18). If you are wondering: *Why should I attend the MSA Tucson 2027 Meeting?* Here are our top 7 reasons: 1. For student presenters: receive *f**ree* registration + *financial support* for travel and meeting costs. 2. Share and hear the best and the breadth of the Mineral Sciences in our *all-plenary oral sessions.* 3. Enjoy *l**ow-cost registration* that includes lunches, coffee/tea breaks, and a reception at a mineral museum. 4. Attend the Tucson Gem & Mineral Show – the *world’s premier mineral event:* “Come for the show and stay for the MSA meeting!” 5. Go on a f*ield trip* to a classic Arizona mineral locality or other interesting site in or near Tucson. 6. Enjoy *mingling with students and colleagues *at hosted lunches, poster sessions, and the reception. 7. Experience spectacular Arizona landscapes and (we hope) pleasant *“escape from winter” weather *(for those who need it). We think that is already an excellent list, but stay tuned for information about additional meeting-related events as planning progresses. *Abstract submission deadline: October 31* Please consider attending the MSA Tucson 2027 meeting. We hope to see you there! Jeff Post & Donna Whitney MSA Tucson 2027 planning co-chairs *Questions?* Email us at postj@si.edu and dwhitney@umn.edu
