NASA – Gravity Assist (2017-now)
NASA’s Gravity Assist podcast is about a virtual journey through the Solar System and beyond. It is hosted by Jim Green, NASA’s Chief Scientist, and various great scientists appear as guests through the various episodes. The title “Gravity Assist” refers to the slingshot effect a spacecraft gets when using the relative movement and gravity of a planet or another object to change its speed or redirect its course. One peculiarity of this show is that each guest has to reveal the “gravity assist” that propelled them into their field of research.
