This month, Stereo Chemistry is sharing an episode of Third Pod from the Sun, a podcast from the American Geophysical Union, featuring an interview with retired astronaut and former professional athlete Leland Melvin. In the episode, Melvin describes how an early⁠—and explosive⁠—interest in chemistry grew into a scientific career at NASA and two missions to the International Space Station.
