About

Jill McGuire is a pioneering aerospace engineer whose work at NASA’s Goddard Space Flight Center has advanced the frontiers of on-orbit satellite servicing and cryogenic fluid management. Her research centers on robotic refueling technologies, space-based cryogen transfer, and autonomous servicing systems—critical capabilities for extending the lifespan of satellites and enabling deep-space exploration. McGuire’s most notable contribution is her leadership of the Robotic Refueling Mission-3 (RRM3), an external payload on the International Space Station that successfully demonstrated the first-ever storage and transfer of cryogenic fuel in orbit. This landmark achievement, documented in her highly cited 2020 overview (20 citations), paves the way for future missions that can refuel spacecraft in space, reducing launch costs and mission risks. Earlier, she contributed to the Hubble Robotic Servicing and De-orbit Mission, developing risk reduction strategies for autonomous rendezvous and robotic repair tasks like gyroscope and battery replacement. With over two decades of experience, McGuire’s work has fundamentally reshaped how we approach satellite longevity and in-space resource utilization, making her a key figure in the next generation of sustainable space operations.
