The available launch periods are based on the constantly changing positions of the Earth and moon, the desired lunar orbit for the Orion spacecraft and the power of the SLS rocket to put it on the resulting trajectory. Monday is an available target date as is Tuesday, although the latter option would have a shorter window.Įither way, if the SLS isn't off the pad by Tuesday, the rocket will have to be hauled back to the Vehicle Assembly Building to service batteries in its self-destruct system, a requirement that has nothing to do with the hydrogen leak. NASA managers said earlier a launch attempt Sunday was possible, but only if propellants were not loaded aboard the rocket. It's not yet known whether any repair attempts will be attempted or whether any additional launch attempts can be made before the current lunar launch period expires Sept. EDT, about 25 minutes after the team recommended "no go" for launch.
Launch Director Charlie Blackwell-Thompson called off today's countdown after multiple unsuccessful attempts to stop a hydrogen leak in an 8-inch quick-disconnect fitting at the base of the SLS core stage. But we're going to show up, and we're going to try, and we're going to give it our best." "There's no guarantee we're going to get off (Saturday).
"We've got a whole host of things that could cause us to not get off on any given day," mission manager Mike Sarafin told reporters at a Thursday evening news conference. The SLS rocket - the most powerful booster NASA and its contractors have ever built - has 489 launch commit criteria that have to be met to permit a liftoff. The Space Launch System moon rocket atop pad 39B on Monday morning, August 29, 2022, awaiting blastoff on a mission to send an uncrewed Orion capsule on a 42-day shakedown flight beyond the moon and back. Launch was initially scheduled for Monday morning, but NASA ran into problems during fueling, forcing the agency to scrub just as the launch window was opening. The Saturday launch, however, was canceled due to a hydrogen leak. EDT Saturday, setting the stage for blastoff at 2:17 p.m., the opening of a two-hour window. With a forecast calling for a 60% chance of favorable weather, engineers began fueling the Space Launch System rocket at around 6 a.m. NASA scrubbed its second attempt to launch its Artemis 1 test flight on a long-awaited mission to send an unpiloted Orion crew capsule on a 37-day trip around the moon and back.
