The following Artemis 1 launch try would possibly happen as quickly as subsequent week, seeing as NASA has met all of the aims it got down to do to contemplate its rocket’s gas check a hit. NASA needed to check including super-cooled gas to the House Launch System’s tanks to substantiate the repairs it made after it scrubbed the mission’s second launch try in late August. The bottom staff at Kennedy House Middle noticed a persistent hydrogen leak affecting one of many gas traces on the SLS on the time and tried to repair it the day of thrice. Ultimately, the staff was unsuccessful and determined to postpone the mission.
The staff decided a number of days later that the leak was triggered when the SLS rocket’s core booster tank went by a quick overpressurization. To stop the identical incident from taking place, the staff adjusted procedures for filling the rocket’s tank with propellants, and it entails transitioning temperatures and pressures extra slowly to stop speedy adjustments that might trigger leakage. The staff’s engineers additionally changed the rocket’s liquid hydrogen seals after discovering a small indentation in one in all them which will have contributed to the leak.
Whereas the engineers encountered one other hydrogen leak in the course of the gas check, their troubleshooting efforts labored this time round and acquired the leak to “inside allowable charges.” That allowed them to conduct the pre-pressurization check, which introduced up the liquid hydrogen tank’s stress stage to match what it might expertise simply earlier than an precise launch.
Artemis 1 launch director Charlie Blackwell-Thompson stated the check went “very well” and that the staff was capable of accomplish all of the aims it got down to do. NASA will now consider knowledge from the check earlier than deciding if it could actually schedule one other launch for the mission on its goal date of September twenty seventh.
