6:30 pm – Main Presentation
Title: The Latest Cutting-Edge Analysis of Apollo Lunar Samples
Speaker: Jessica Barnes is an Assistant Professor at the Lunar and Planetary Laboratory, University of Arizona. She completed her undergraduate and Ph.D. training in her native UK, and was a postdoctoral fellow at NASA’s Johnson Space Center in Houston. Jess’s research background is in lunar mineralogy and geochemistry. Her current research centers on the origin and evolution of inner solar system volatiles.
In preparation for future lunar missions in the 2020s and beyond, it is important to maximize the science derived from samples returned by the Apollo Program. By applying cutting-edge analytical techniques to Apollo samples we address both longstanding and new scientific questions. NASA’s Apollo sample collection includes a subset of samples that were specially curated in 1972 and have remained untouched and unstudied since then. The Apollo Next Generation Sample Analysis (ANGSA) initiative was designed to examine these pristine samples. Jess will talk about the preliminary examination of a never-before-studied lunar drill core and plans for the analyses of a frozen piece of lava from the Moon.
7:15 pm (Approx) – Second Presentation
Title: Seasonal Night Sky Object
Speaker: Mary Turner
Mary Turner, TAAA’s appointed Chief Observer, takes us on an tour of the summer night sky. As usual in her popular talks, Mary’s use of astronomical data, images, and mythology brings the seasonal changes in the sky to life.
