The Double Asteroid Redirection Test (DART) is a focused spacecraft, designed to navigate to and impact an asteroid at a speed of 6.6 kilometers per second (roughly 15,000 miles per hour). It will be the first planetary defense test mission, demonstrating our capability to respond to a potential asteroid impact threat, should one ever be discovered. Join the DART Mission Coordination Lead and Planetary Scientist, Nancy Chabot (PhD), to learn how her team is setting the asteroid Dimorphos on a new orbit later this year.


NCNancy L. Chabot, PhD, is the Planetary Chief Scientist at APL. She is a planetary scientist whose research focuses on understanding the formation and evolution of rocky planetary bodies in our Solar System. At APL, she oversees the Meteorite Lab, which is used to conduct geochemical experiments and investigate meteorites and other extraterrestrial materials. She has been a member of five field teams with the Antarctic Search for Meteorites (ANSMET) program and is a Fellow of the Meteoritical Society. On NASA’s MESSENGER mission, she served as the Instrument Scientist for the Mercury Dual Imaging System (MDIS) and the Chair of the Geology Discipline Group. Currently, she is the Coordination Lead on NASA’s Double Asteroid Redirection Test (DART) mission, the Deputy PI for the Mars-moon Exploration with GAmma rays and NEutrons (MEGANE) instrument on the JAXA Martian Moons eXploration (MMX) mission, and an Interdisciplinary Scientist on the joint ESA-JAXA BepiColombo mission. Asteroid 6899 Nancychabot is named in her honor.  

kaKeri N. Althoff, PhD, is the Provost’s Fellow for Research Communication and an associate professor of epidemiology in the Bloomberg School of Public Health and the School of Medicine. As a Provost’s Fellow, she is expanding our institutional capacity to share research achievements. Dr. Althoff's research interest is aging in the context of human immunodeficiency virus (HIV) infection. She serves as the co-director of the North American AIDS Cohort Collaboration on Research and Design (NA-ACCORD), which is a collaboration of more than 20 longitudinal HIV cohort studies of adults with individual-level harmonized data. She earned her bachelor's degree at the University of Iowa, then her MPH and PhD from the Johns Hopkins Bloomberg School of Public Health. Prior to becoming an accomplished epidemiologist, Dr. Althoff worked in public relations and journalism. Her skills and passion for sharing research with broad audiences make her the perfect host for Hopkins on the Hill at Home 2021.
