Artemis 1 Launch Date and Mission Overview
Artemis 1 launched on November 16, 2022, from Kennedy Space Center in Florida, marking the first integrated flight test of NASA's Space Launch System and Orion spacecraft. The mission was designed to send an uncrewed Orion capsule around the Moon and back to Earth to validate systems before crewed flights NASA Artemis Missions.
The launch took place at 06:47 UTC from Launch Pad 39B, with the SLS rocket producing 8.8 million pounds of thrust. The mission lasted 25 days, 10 hours, and 53 minutes, ending with a splashdown in the Pacific Ocean on December 11, 2022, completing all primary objectives successfully.
Key Technical Details and Flight Profile
Rocket and Spacecraft Configuration
The Space Launch System Block 1 variant used for Artemis 1 was the most powerful rocket NASA had flown, standing 322 feet tall with a core stage and two solid rocket boosters. Orion was equipped with European Service Module provided by the European Space Agency, housing propulsion, power, and life-support systems for future crewed missions ESA European Service Module.
Trajectory and Lunar Operations
After Earth orbit insertion, the Interim Cryogenic Propulsion Stage performed a trans-lunar injection burn, sending Orion on a trajectory beyond the Moon. The spacecraft reached a maximum distance of about 268,563 miles from Earth, setting a new record for the farthest distance traveled by a spacecraft designed to carry humans Space.com Artemis 1 Records. It entered a distant retrograde orbit around the Moon for approximately six days before returning.
Mission Outcomes and Program Significance
Artemis 1 demonstrated the integrated performance of the SLS rocket, Orion spacecraft, and ground systems, with all critical systems operating within expected parameters. The mission validated heat shield performance during lunar-return reentry speeds of about 24,500 miles per hour and confirmed communication, navigation, and flight control systems Forbes Artemis 1 Review.
As the first step in NASA's Artemis campaign, the successful completion of Artemis 1 cleared the path for Artemis 2, which will carry astronauts around the Moon, and Artemis 3, targeting a crewed lunar landing. The mission is managed by NASA's Marshall Space Flight Center, with primary contractors including Lockheed Martin for Orion and Boeing for the SLS core stage.
