In his first segment, Obama talks about NASA astronaut Scott Kelly's recent return to Earth, after spending 340 days in orbit. NASA scientists hope to learn more about the effects of long-term space travel on the human body by studying Kelly. He's a particularly well-suited candidate, given he has an identical twin, Mark Kelly, who stayed on Earth that whole time.

Other topics Obama will cover include new, minimally-invasive ways of tapping into brain waves, how big data is improving cancer treatment, and the story of Henrietta Swan Leavitt -- one of astronomy's most influential, but often-overlooked, figures.
