KENNEDY SPACE CENTER, Fla. - CURRENT ARTEMIS I UPDATES:
5:00PM | NASA said it discovered another hydrogen leak with the Artemis I rocket, which will further delay its next launch opportunity. NASA said the rocket will have to be rolled back to the Vehicle Assembly Building, and that the next launch opportunity could not be until later in September, potentially into October.
12:40 p.m. | NASA Administrator Bill Nelson said that the mission will happen "when it's ready." "We're going to make sure it's right before we put four humans up on the top of it," he said. "This is part of our space program: be ready for the scrubs." The next opportunity is expected to be on Monday, Sept. 5 with a 90-minute launch window that opens at 5:12 p.m. ET.
11:17 a.m. | The #Artemis I mission to the moon has been postponed. Teams attempted to fix an issue related to a leak in the hardware transferring fuel into the rocket, but were unsuccessful. Next launch opportunity is on Monday, Sept. 5 with a 90-minute launch window that opens at 5:12 p.m. ET.
11:15 a.m. | The NASA engineers have suggested a no go for today’s launch. NASA’s Launch Director wants to hold. She has not decided to scrub yet.
10:55 a.m. | During tanking of the #Artemis I mission, a leak developed in the supply side of the 8-inch quick disconnect while attempting to transfer fuel to the rocket. Attempts to fix it so far have been unsuccessful. Stand by for updates.
