Live updates: NASA Artemis I moon rocket set for launch

NASA is once again attempting to launch its giant Space Launch System and Orion spacecraft to the moon. The two-hour launch window opens at 1:04 a.m. and if all goes well, the rocket will propel the autonomous spacecraft, without any astronauts on board, on a test flight scheduled to last 25 days, 11 hours and 36 minutes, ending with a splashdown in the Pacific Ocean off the coast of San Diego.
