NASA Artemis 1 Launch

On Nov. 16, 2022, the Orion spacecraft launched aboard the Space Launch System (SLS) rocket from NASA's Kennedy Space Center and embarked on the #Artemis I mission to the Moon and back. Orion orbited the Moon, getting as close as 79 miles to the lunar surface, and successfully splashed back down to Earth 25.5 days later on Dec. 11. Four RS-25 engines and two five-segment solid rocket boosters provided more than 8.8 million pounds of thrust for SLS during liftoff and flight. Thanks in part to development of a new RS-25 engine controller that checks engine health 50 times per second, engineers were able to collect more than 100 measurements on pressures, temperatures, flows, speeds, and vibrations on the four RS-25 engines that helped power Artemis I.
