NASA's Artemis 1 mission is poised to take a key step toward returning humans to the moon after a half-century hiatus. The launch was scheduled for the morning of Aug. 29, 2022, but was postponed due to an issue with one of the rocket's engines. The next opportunity to launch the rocket is Sept. 2, 2022. The mission is a shakedown cruise—sans crew—for NASA's Space Launch System and Orion Crew Capsule.
