NASA successfully completes important fuel test for Artemis 1 rocket


The next Artemis 1 launch attempt could happen as soon as next week, as NASA has already achieved all of the goals it set for its rocket review. successful fuel test. NASA had to test adding super-cooling fuel to the Space Launch System’s containers to confirm the repairs it made afterwards. wash the mission’s second launch attempt in late August. The ground team at Kennedy Space Center detected a persistent hydrogen leak affecting one of the fuel lines on the SLS at the time. that point and tried to fix it during the day three times. In the end, the team was unsuccessful and decided to postpone the mission.

Team determined A few days later, the leak was triggered when the core booster tank of the SLS rocket experienced a brief overpressure. To prevent a similar incident, the team tweaked the procedure for filling the rocket’s barrel with propellant, and it involved slower temperature and pressure transitions to prevent rapid changes. may cause leakage. The team’s engineers also replaced the rocket’s liquid hydrogen seals after discovering a small dent in one of them could be the cause of the leak.

While the engineers encountered another hydrogen leak during fuel testing, their troubleshooting efforts worked this time and the leak was “within the limits”. That allowed them to conduct pre-pressurization testing, which raised the pressure level of the liquid hydrogen container to match what it would experience just before the actual launch.

Artemis 1 premiere director Charlie Blackwell-Thompson said the test went “very well” and the group was able to accomplish all the goals set by the group. NASA will now evaluate data from the test before deciding if it can schedule another launch for the mission on its target date. September 27.
