SPEXcast sits down with Holly Griffith, Vehicle Systems Engineer for ECLSS on Orion Program in Safety and Mission Assurance and a former Shuttle flight controller. We ask her about her experiences sitting in on the return to flight launch of the Shuttle in 2005, her most stressful day on the job, as well as her new work on Orion. We also geek out over her Star Wars fandom, and discuss her mission to encourge women to join STEM fields. Check her out on social media @absolutspacegrl
