RVAS Monthly Meeting: Monthly meetings will resume on Monday, February 16 at 7:30pm, and are held at the VWCC STEM building ST314.


Our speaker will be Dr. Caitlin Ahrens, who will discuss cryovolcanoes.


Dr. Caitlin Ahrens received her B.S. in Astrophysics and Geology from West Virginia University in 2015, and a Ph.D. in Space and Planetary Science at the University of Arkansas in 2020. Dr. Ahrens is currently an assistant research scientist from the University of Maryland working at NASA Goddard Space Flight Center, and a member of the Diviner Science Team with the Lunar Reconnaissance Orbiter. Ahrens' research involves remote sensing of icy surfaces and volatile interactions, including ice at the lunar poles and cryovolcanism in the outer solar system. Dr. Ahrens also works on several planetary volcanism projects, including Mars, Ceres, Titan, and Pluto, and civil engineering on the Moon!


Ice isn’t just cold, it’s weird! We’re going to dive into the many varieties of cryovolcanism across our Solar System, from the salty and muddy puddles to the magnificent ice geysers. We’ll see what makes cryovolcanism so interesting to research, and how volcanoes differ between rocky and icy surfaces. .
