Gravity Assist: Walking on Broken Ice, with Catherine Walker

Gravity Assist: NASA's Interplanetary Talk Show

An ice shelf collapsed in East Antarctica in March 2022, concerning scientists who track melting glaciers, sea level rise, and other effects of climate change. Catherine Walker, a visiting scientist at NASA’s Goddard Space Flight Center, uses NASA satellite data to look at the progression of events like this one to understand how large ice structures collapse. She is also looking at Jupiter’s moon Europa and what kind of life might be able to survive under the ice there. Learn about her Antarctica adventures and her scientific journey on this episode of Gravity Assist.
