"AND 4 TO...HOLD! - MISSED IT BY THAT MUCH." Report details from collectSPACE: August 29, 2022 — An issue with cooling a rocket engine forced NASA to call off its first attempt at launching a spacecraft on a test flight to the moon. As a planned course of action during the countdown, launch controllers were set to condition the SLS's core stage engines — four RS-25 engines rre-purposed from the space shuttle program — by increasing pressure on their liquid hydrogen tank to bleed some of the cryogenic propellant to the engines to get them to the proper temperature range needed at ignition. One of the four engines (no. 3, serial number 2058) was not properly conditioned even after the liquid hydrogen tank was fully pressurised. September 3, 2022 — NASA's second attempt at launching its first new "mega moon rocket" in 50 years ended in a scrub on Saturday (Sept. 3), after engineers were unable to correct for a liquid hydrogen leak. Mission managers have made the decision to fore-go trying again this upcoming week and instead are standing down to give time for engineers to understand and repair the leak. Saturday's leak was unrelated to a hydrogen leak during the first launch attempt on Monday (Aug. 29). The earlier issue had been in a tail service mast umbilical and was repaired in the days leading up to Saturday's attempt. Patch Description: Since both of these scrubs dealt with the issue of fuelling the rocket, I created this design in an attempt to illustrate the tail service mast and where it connects to the SLS Core Stage. On each side of the "H" in "HOLD" is the "L and 2" that complete the chemical identifier for Liquid Hydrogen. The "A" in the word "THAT" is illustrated by the Hydrogen atom because as noted in the reports, hydrogen is the smallest atom and therefore a difficult compound to control.
