11/29/2023 0 Comments Artemis 1 live5, its next launch try would likely be in October, mission managers have said. 3 issue, it could try to launch again Friday (Sept. With NASA unable to launch today, the agency could try for one of at least two back-up days on which to fly Artemis 1 on its mission to the moon. Offshore storms and lightning delayed fueling of the SLS rocket by nearly an hour, forcing launch controllers to work to catch up for lost time. NASA stopped and restarted the flow of liquid hydrogen into the tank in an attempt to verify the leak and even proceeded with fueling the 322-foot-tall (98 meters) rocket's upper stage while engineers worked the issue.Įven before fueling the SLS rocket, NASA faced challenges during Monday's launch countdown. "Although a similar issue was identified in an earlier wet dress rehearsal, it may not necessarily be the same cause," NASA officials wrote in a subsequent update. But NASA officials were not quick to judge. The leak during the fueling process appeared similar to one that occurred during an SLS fueling test earlier this year, Nail noted. 3 problems and the feared crack followed concerns about a liquid hydrogen leak in the rocket. Nail added that NASA personnel had seen similar cracks in the foam when it was used on the space shuttles before their retirement in 2011. "That ice that formed is essentially air that's being chilled by the tank that gets trapped inside of a crack in the foam but not the actual tank," Nail said. NASA engineers found that the crack was actually in the insulating foam on the flange, not in the rocket's metal structure. "The flanges are connection joints that function like a seam on a shirt, are affixed at the top and bottom of the intertank so the two tanks can be attached to it," NASA said in the update. The tanks can hold a combined 730,000 gallons (3.3 million liters) of propellant. 3 conditioning issue cropped up as NASA worked through a series of glitches during the countdown, including a liquid hydrogen leak early in the fueling process and a possible crack in a part of core booster known as the intertank flange, which connects the SLS's giant liquid hydrogen and liquid oxygen tanks.
