NASA’s interplanetary talk show, hosted by Chief Scientist Jim Green, introduces you to space professionals working to take exploration into the future.
Gravity Assist: Lucy and the Space Fossils, with Hal LevisonTo get a more complete understanding of the full history of our solar system, NASA is sending a spacecraft called Lucy to investigate the Trojans, mysterious small objects that share an orbit of the Sun with Jupiter. Principal investigator Hal Levison of the Southwest Research Institute
Gravity Assist: Goodbye Saturn, Hello Earth, with Janelle WellonsJanelle Wellons likes to say that she operates “fancy space cameras.” At NASA’s Jet Propulsion Laboratory, she creates commands that allow spacecraft to take valuable scientific data in our solar system and here at planet Earth.
Gravity Assist: Freaky Physics on the Space Station, with Ethan ElliottThe laws of physics get very, very weird in the realm of particles too small for the eye to see. Aboard the International Space Station, an experiment called the Cold Atom Laboratory (CAL) is exploring how the universe works .
Gravity Assist: Diving Into NASA History, with NASA Intern Felicia RagucciIn honor of National Intern Day, Gravity Assist features Felicia Ragucci, an undergraduate at Dartmouth College who recently completed an internship with NASA’s History Office and the Office of the Chief Scientist. During her time at NASA, Felicia researched the history of the Neutral Buoyancy Simulator, an underwater training facility where astron
Gravity Assist: Onward to Venus, with Lori GlazeNASA is sending two missions to Venus this decade and participating in a European Space Agency mission there, too. Lori Glaze, director of planetary science at NASA, discusses these missions and why she’s so excited about what we’re about to learn.
Gravity Assist: A Dream, a Team, a Chance to Fly on Mars, with MiMi AungThe idea for NASA’s Mars Ingenuity helicopter began at the Jet Propulsion Laboratory with a team of dedicated engineers who believed in something seemingly impossible. MiMi Aung served as the project manager on the helicopter, which has now achieved nine flights on Mars.
Gravity Assist: This Asteroid Is Metal, With Lindy Elkins-TantonScientists will soon have the opportunity to visit a unique object in the asteroid belt called Psyche, which may be the exposed metallic core of a planetary body that stopped growing before it became a big planet like Earth. Dr. Lindy Elkins-Tanton explains.
Gravity Assist: Let’s Talk About Climate Change, with Gavin SchmidtWhat’s the difference between climate and weather? How does NASA monitor changing sea levels, melting glaciers, and other effects of climate change? Gavin Schmidt, NASA’s acting senior climate advisor, explains how rising temperatures lead to many complex changes both in the oceans and on land.
Gravity Assist: From Space Camp to Mission Control, with Tara RuttleyHow do astronauts exercise on the International Space Station? How do they train underwater? Tara Ruttley, associate chief scientist for microgravity research at NASA Headquarters, has worked on a lot of fascinating projects to support the human spaceflight program.
Gravity Assist: Before You Launch: Practice, Practice, PracticeWhen future astronauts explore the surfaces of the Moon, Mars, or beyond, they’ll have big challenges communicating with Mission Control back on Earth.
