CLASS/FSI Seminar Series: Fall 2019 featuring Kelsi Singer, SwRI

October 22, 2019 @ 8:30 am PST - 9:30 am PST

CLASS/FSI Seminar: Dr. Kelsi Singer, SwRI


TITLE: New Horizons: Exploration of Distant Worlds in the Kuiper belt PRESENTER: Dr. Kelsi Singer, SwRI   ABSTRACT: In July of 2015 the New Horizons spacecraft flew through the Pluto system, initiating humanity’s close-up exploration of the Kuiper belt objects. Pluto turned out to be a world of remarkable geologic diversity, and its terrains display a range of ages, suggesting geologic activity of various forms (both endogenic and exogenic) has persisted for much of Pluto’s history. Pluto’s large moon Charon appears to have had an early large cyrovolcanic resurfacing episode along with large-scale tectonism. On January 1 of 2019 (yes this year!) New Horizons encountered its second target, a cold classical Kuiper belt object approximately 35 km across at 43 AU. This is the farthest and most primordial planetary body ever explored in detail. Its flattened snowperson-like shape and unique surface features are helping us learn about the earliest times in the solar system and how planetary bodies formed. The success of this exploration was enabled by scientific work and technology developed across the globe. The information gathered by New Horizons is opening up new areas of research and providing new input into solar system formation models. I will highlight recent results and expand on whichever topics are of interest to the audience in this interactive presentation. About Dr. Kelsi Singer: Dr. Kelsi Singer is a Senior Research Scientist at Southwest Research Institute in Boulder, CO and a Deputy Project Scientist on NASA’s New Horizons mission. Dr. Singer obtained her PhD at Washington University in St. Louis and her thesis focused on the geology and geophysics of icy satellites. She studies the Pluto-system, the Kuiper belt, and also impact cratering across the solar system.
