Allison Mjoen, NASA's operations manager for the Exploration Ground Systems Program, stood with her family on April 1, 2026, as the Space Launch System ignited at Kennedy Space Center. The clear Florida morning drew a crowd that counted down alongside her children, who witnessed the culmination of two decades of her work supporting shuttle, station and now Artemis missions.

Mjoen's career began as a flight crew systems engineer for the Space Shuttle Program, where she managed cabin configurations including food, spacesuits and cargo. She later integrated experiments for the International Space Station and served as lead for Artemis vehicle processing before earning certification as an operations project engineer during integrated firing room tests for Artemis I.

"Every decision and communication directly supported the integrated team's ability to execute safely," Mjoen said of her role coordinating booster and Orion spacecraft operations. Her current responsibilities involve developing integration plans and overseeing ground operations that prepare Artemis vehicles for launch.

The launch moment offered reflection on how Artemis builds on Apollo's legacy of collective achievement. Mjoen noted that while Apollo demonstrated what was possible, Artemis aims to create a sustained presence on the Moon that future generations can share.

Her work continues to emphasize preparation, collaboration and trust across teams as NASA advances toward returning humans to the lunar surface.
