11/13/2023 0 Comments Nasa live coverageEDT: Attempts to fix a hydrogen leak impacting today’s Artemis I launch haven’t worked, according to the latest NASA update. Liquid hydrogen (LH2): 9% filled and holdingĩ:35 a.m.Liquid oxygen (LOX): 99% filled and topping.Managers hope the stop-go process will help reseat the connection and resolve the issue. EDT: In an effort to fix a hydrogen line leak, NASA will let it warm up before pushing through supercooled liquid hydrogen again. Otherwise, the LH2 loading process is way behind as you can tell from the latest fill percentages:ġ0 a.m. EDT: After letting the leaky line warm up, NASA is again starting to flow supercooled hydrogen into the SLS rocket. EDT, but you can expect this to shift to later in the two-hour window – or we see a scrub. Teams will meet and discuss next options, but it's safe to say things aren't looking good. EDT: NASA reports a third attempt at fixing the ongoing hydrogen leak didn't work. Just waiting for Launch Director Charlie Blackwell-Thompson to make the official call based on meetings with her team. To be clear, it's safe to say today's launch has been scrubbed due to the hydrogen leak issue. Pretty safe to say today will be a scrub. That will now go to the launch director, who will most likely approve that. EDT: The launch team is recommending a "no-go" status for today's Artemis I liftoff. Scrub recommendation presented to LDġ0:55 a.m. EDT: Launch Director Charlie Blackwell-Thompson, who was presented with a recommendation to scrub today's attempt a few minutes ago, said she would like some more time to confer with teams before officially waving off today's flight. Launch director wants more timeġ1:10 a.m. There are opportunities available Monday and Tuesday, but will depend on a fix. SCRUB! No Artemis I launch today primarily due to the hydrogen leak issue. More details are expected early next week. Officials also said the hydrogen leak could potentially be fixed at the pad.īut as it stands, the Space Force has not granted an extension and the leak, located in the lower portion of the 322-foot rocket, will most likely need to be fixed in the VAB. The military branch is in charge of public safety during launches, so it's their call. It needs to be re-certified – an operation that can only be done in the VAB – every 25 days, but officials said the Space Force might be willing to grant an extension. One of the main reasons for a VAB rollback is the termination system, which destroys the rocket in case it veers off course or sees some other emergency issue. But he cautioned that it was too early to rule out late September or early October. Rolling back to the VAB for repairs, certifications, and preparations for another rollout to pad 39B would take "several weeks," Sarafin said. While officials said that timeline is possible, it appears more likely that Artemis I won't be ready to fly again until yet another two-week opportunity opens Oct. "This was not a manageable leak," Artemis I Mission Manager Mike Sarafin told reporters Saturday.Īnother roughly two-week launch window opens Sept. Saturday's attempt saw the liquid oxygen tank 100% filled, but the hydrogen tank only hit about 10% before the scrub was called. SLS uses liquid oxygen and liquid hydrogen as propellants. The issue was severe enough to call off all remaining launch opportunities in this Earth-to-moon window that closes after Tuesday, Sept. 3, attempt was scrubbed primarily due to a large hydrogen leak at pad 39B. NASA officials on Saturday said teams were planning to roll the 322-foot SLS rocket back to the Vehicle Assembly Building for repairs and recertifications, likely meaning a delay for the Artemis I flight to late this month but most likely sometime in October.Ī 2:17 p.m. Briefing: SLS won't fly for several weeks There is no crew aboard.įollow live updates below (manual refresh required follow this link for more frequent, real-time updates). If it takes off on time, this mission will take Orion on a 38-day mission to the moon and back. If they need it, teams have a two-hour window to fly from pad 39B. The 322-foot rocket and Orion capsule have a two-hour window to fly from Kennedy Space Center in Florida, where weather conditions are expected to be 60% "go" at liftoff. 3, for the launch of its massive Space Launch System rocket on a mission to the moon known as Artemis I.
