Por NASA Podcast #Recomendado Tweet Gravity Assist: Walking on Broken Ice, with Catherine Walker 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.

Por NASA Podcast #Recomendado Tweet Gravity Assist: The History of the Future, with Steven Dick People have long wondered whether there is life beyond Earth, but it is only recently that scientists have been able to apply the tools of space exploration to go after this question. In 1996, the Allan Hills 84001 Meteorite shook the world as scientists debated whether it had tiny fossils inside of it that came from Mars. The consensus is that this rock does not contain Martian fossils, but the questions it raised energized many researchers. Today, the field of astrobiology is looking at how life arose on Earth and where else in the solar system and beyond life could exist. Beyond these scientific investigations, there are also philosophical questions one could ask. Would we be ready as a society for such a groundbreaking discovery? Astronomer and historian Steven Dick tells us there are many approaches to consider and many questions we should ask ourselves to get ready, in case extr...

Por NASA Podcast #Recomendado Tweet Gravity Assist: What is Astrobiology? With Mary Voytek How did life originate and evolve here on Earth? What form could life take elsewhere – and where else could life survive beyond our planet? These are questions that scientists called astrobiologists tackle every day. By using space telescopes, doing laboratory experiments and studying extreme environments on Earth, astrobiologists hope to uncover new insights about what it means to be “life” and get more clues to the ultimate question: Are we alone in the universe? Mary Voytek, head of NASA’s astrobiology program, discusses in this episode.
