Cathy Olkin (@colkin) is a planetary scientist at Southwest Research Institute in Boulder, CO. Her main topic of research is the outer solar system, specifically planetary atmospheres and surfaces. She is the Deputy Project Scientist for NASA’s New Horizons mission to Pluto and the Kuiper Belt. The New Horizons mission provided the first close-up images of Pluto and its moons in 2015. It is currently en route to encounter a close classical Kuiper Belt object nicknamed Ultima Thule. She is also the Deputy Principal Investigator for NASA’s Lucy mission. The Lucy mission will be the first spacecraft to visit the Trojan asteroids. Cathy also carries out ground-based observations including stellar occultations to learn about the size and atmosphere of small worlds and is the current Chair of the Division for Planetary Science of the American Astronomical Society.
In her free time, Cathy mentors FIRST robotics programs providing hands-on STEM education for students from 4th grade to 12th grade.
Andy is a planetary astronomer at the Johns Hopkins University Applied Physics Laboratory in Laurel, MD, with his research focusing on the composition of asteroids. In particular, he is interested in those asteroids that have evidence of water or organic materials in them, detectable in their infrared reflectance spectrum. This pursuit has led to studies of asteroids all over the inner solar system, from dwarf planets to objects that can fit inside a sports stadium.
In addition to observational work, Andy has been active in the broader near-Earth object community, serving as a team member in several efforts to understand and report the impact hazard we face and how to lessen it, including serving as Investigation Lead for the DART mission scheduled to conduct a planetary defense demonstration in 2022. Finally, Andy is the Principal Investigator of the MANTIS mission concept, which if selected by NASA will conduct an asteroid tour in the 2020s.
The other 51 weeks of the year, you can find Andy at @asrivkin.
Saramoira Shields (@mathematigal) is an engineer working for the Space Systems Design Studio at Cornell University. The SSDS is a multifaceted research lab, with active projects in small-scale satellite design, rover design, interstellar and inter-orbit navigation, flux pinning and and non-contact actuation. Previously, she has worked for the Cornell High-Energy Synchrotron Source, as well as for the Cornell Astronomy Instrumentation Group, on the ARCoIRIS ad ZEUS-2 spectrographs. She started out in pure mathematics, and still noodles around in it from time to time. She also loves ultramarathoning, distance hiking, dragon boating and spending quality time with her two cats, Parsec and Ligo.
