The History of Lunar Volcanology

Our speaker will be Colton Freeman. Colton is a Student Ambassador for the Oregon Space Grant Consortium (OSGC) and a senior Geology student at Oregon State University. Many organizations have been making a strong push toward further exploring and developing the lunar surface for scientific and industrial purposes. These goals require careful thought about where the resources needed to support these efforts are located and how to access them. The Moon is also a harsh environment with temperatures ranging from -170 degrees C to 120 degrees C, intense radiation, weak gravity, pernicious dust, and, of course, no atmosphere. The most prominent features of the Moon visible from Earth are the maria, which are enormous volcanic flows from the distant past, punctuating the importance of volcanism in lunar history. As a budding geologist and space enthusiast, Colton has been learning about the geological history of the Moon and sharing what he has learned. He'll tell us about this key component in lunar history. It will be fun to hear what he has learned and it would be fun to have you join us!
