John McCullough, a 1989 graduate of the University of Cincinnati, has played an important role in NASA’s Artemis I and Artemis II missions to the moon, according to a May 19 announcement from the university.
McCullough’s involvement is significant as it highlights how alumni from local institutions are contributing to major national space exploration efforts. The Artemis program represents NASA’s ongoing mission to return humans to the moon and eventually reach Mars.
After earning his degree in aerospace engineering from the University of Cincinnati, McCullough worked at McDonnell Douglas Corporation before joining NASA. He has been with NASA for more than three decades and has held various leadership positions. “I remember watching the moon landing and thinking, ‘That’s what I want to do.’ The idea that I’ve done it — that I’ve helped put people on the other side of the moon and go farther than they’ve ever been — is full circle for my career,” McCullough said.
Throughout his time at NASA, he contributed to several historic programs including the space shuttle, Hubble Space Telescope, International Space Station, and human exploration projects such as Constellation and Artemis. From 2008 to 2012 he served as chief flight director for human space flight at NASA. In this capacity he was responsible for selecting flight directors and ensuring operational readiness for missions. He also assigned the lead flight director for Artemis I.
For seven years, McCullough led vehicle integration for Orion—the spacecraft used in Artemis missions—ensuring all requirements were met so that it would be safe for human crews. “Human rating a new deep-space vehicle is a unique exploration challenge to Artemis,” McCullough said. He added: “Orion was the first in that challenging environment beyond low Earth orbit since Apollo… If there’s an issue on a cargo or robotic flight, it’s an issue of mission success, not typically life or death as it is with crewed flights.” As Director of Exploration at Johnson Space Center from 2019-2023 he oversaw six divisions supporting both Artemis and broader Moon-to-Mars programs.
“We all feel very close as a team and family when it comes to making sure that our crews are safe; we really take that to heart in everything we do,” he said about working on these projects.
Currently serving as deputy associate administrator for Integration within NASA’s Exploration Systems Development Mission Directorate at headquarters, McCullough continues his work overseeing human exploration initiatives including future lunar bases. He reflected: “In my career I have had many outstanding opportunities to contribute to human spaceflight… It was a childhood dream come true for me; UC’s co-op program really made a difference.” Plans are underway for further missions under Artemis with additional hardware being developed.
