NASA Engineers Assess Data After Artemis I Launch Scrub

NASA will host a media teleconference Tuesday, August 30, at roughly 6 p.m. EDT (3 p.m. PDT) to supply an upgrade on information analysis and conversations. Keep in mind that the time goes through change. While supervisors have actually not yet set a date for the next launch attempt, the earliest possible opportunity is Friday, September 2, throughout a two-hour launch window that opens at 12:48 p.m.

Engineers are assessing information collected throughout the Artemis I launch attempt on Monday, August 29, which was stopped by the launch director at roughly 8:34 a.m. EDT (5:34 a.m. PDT). The launch was scrubbed after groups could not get the rockets engines to the proper temperature range needed to start the engines at liftoff, and ran out of time in the two-hour launch window to continue. NASAs new deep-space rocket, the Space Launch System (SLS), will launch missions powered by four RS-25 engines, trustworthy engines utilized for 135 shuttle objectives.

Engineers are examining data collected throughout the Artemis I introduce attempt on Monday, August 29, which was stopped by the launch director at roughly 8:34 a.m. EDT (5:34 a.m. PDT). The launch was scrubbed after teams could not get the rockets engines to the correct temperature level variety required to begin the engines at liftoff, and lacked time in the two-hour launch window to continue. The mission management team will convene on Tuesday afternoon to talk about the data and establish a plan forward.
The 4 RS-25 engines on the Space Launch System should be thermally conditioned before extremely cold propellant begins streaming through them for liftoff. Release controllers condition them by increasing the pressure on the core stage liquid hydrogen tank to path, or “bleed” as it is typically called, a portion of the approximately minus 423 ° F liquid hydrogen to the engines. Supervisors presume the issue, seen on engine 3, is unlikely to be the outcome of a problem with the engine itself.
NASAs new deep-space rocket, the Space Launch System (SLS), will release objectives powered by 4 RS-25 engines, dependable engines utilized for 135 shuttle objectives. The engines have been upgraded with new controllers and other features for SLS.
Throughout the countdown, launch controllers overcame several extra issues. These include storms in the location that delayed the start of propellant packing operations, a leakage at the quick disconnect on the 8-inch line used to drain pipes and fill core stage liquid hydrogen, and a hydrogen leakage from a valve utilized to vent the propellant from the core phase intertank.
