Leland Melvin’s scientific career began during his childhood in Lynchburg, Virginia, when he created a fantastic explosion in his living room with an at-home chemistry set. Little did Leland or his family know at the time that he would become both a professional athlete and a NASA astronaut, flying two missions to the International Space Station.

In this special episode of AGU’s podcast Third Pod from the Sun, Leland recounts his circuitous journey from scientist to NFL wide receiver to astronaut. His inspirational story of overcoming odds, injuries and setbacks shows how anyone can achieve the impossible with enough determination and discipline.
