Pavicic worked at the engines console during Artemis I. On an earlier launch attempt, he said, a sensor on engine three indicated ambient temperature and did not show liquid hydrogen flowing through it. Launch controllers chill the engines before ignition to protect hardware from liquid hydrogen at minus 423 degrees Fahrenheit, according to NASA. [S1]
After the no-go recommendation, Pavicic and his team worked days and nights rewriting procedures and learning about the engines and sensors, NASA said. Artemis I later lifted off from Kennedy Space Center in Florida in November 2022. [S1]
In July 2025, NASA said Pavicic was helping the launch team develop countdown procedures and launch commit criteria for Artemis II. At the time, NASA planned the first crewed Artemis mission to take four astronauts around the Moon and back over 10 days the following year. [S1]
