This week ESRA wishes to thank Jim Jarvis for all of his hard work as the ESRA Range Safety Officer and Launch Safety Coordinator!

Jim’s journey with ESRA began in 2018, when his work with rocketry teams at local universities led him to discover IREC through Andy Berger. He saw how much potential there was in supporting emerging engineers, so he joined ESRA with the hope of helping the next generation of space scientists gain real, hands-on experience while enjoying the process.

Since then, he has collected memories that stay with him, but one stands out above the rest, which was driving away from the 2019 competition with a Turkish rocket tied to the roof of his truck. He still proudly keeps it today. Jim believes anyone who has experienced the joy of rocketry can make a difference by helping others experience it too.
