“A lot of science is about asking questions. It’s OK to not understand something. And it’s OK that it’s hard. That understanding comes in just being curious. We don’t have all the answers, but we know how to go about looking for them.” Welcome to Season 4 of the On the Job series! This season, you’ll hear from seven women with cool, unique, interesting careers. We’ll learn about the jobs we see on TV — lawyers and nurses and astronauts, oh my! — and we’ll honor some frontline heroes, including an emergency room nurse and a middle school special education teacher. But first, we’re going to space, with real-life rocket scientist Lynn McGrew! Lynn is a NASA aerospace engineer based at the Johnson Space Center in Houston, TX, and on this episode, she talks about the moment she fell in love with space (“For the first time, in the middle of the country, I saw this band of stars across the sky, and I was just fascinated by it. What is this magical view overhead? I was absolutely stunned, and so curious,” she says.), explains how she broke into the competitive field, and talks about her decades-long involvement working on the Mars rovers in the jet propulsion laboratory (“JPL”), including the Phoenix, the Curiosity, and, most recently, the Perseverance. Plus, she talks about how running and cycling fit into her life. SPONSOR: Tracksmith — Go to tracksmith.com/ontherun and use code ONTHERUN for $15 off your first Tracksmith order of $75 or more.
