NASA replaces leaky seals on Artemis 1 moon rocket


“NASA engineers replaced leaky seals on two fuel lines of the Artemis 1 moon rocket over the weekend, setting the stage for a fueling test to see if the repairs worked. … The repair work is aimed at plugging a hydrogen fuel leak in an 8-inch line leading into the core stage of the 32-story SLS rocket. That leak forced NASA to call off a Sept. 3 launch attempt of Artemis 1, the first uncrewed test flight of the Artemis program that aims to return astronauts to the moon. While replacing that seal, engineers also replaced the seal on a smaller 4-inch hydrogen ‘bleed line’ that also saw a leak in a scrubbed Aug. 29 launch try. … On Thursday (Sept. 8), NASA officials said it is targeting Sept. 23 for the next Artemis 1 launch attempt. A Sept. 27 date is also available. Both launch opportunities depend on NASA fixing the fuel leak and the SLS rocket passing its fueling test, the agency said.” (09/11/22)
