NASA began fuel testing from Kennedy Space Center (Florida) at 13:15 Spanish peninsular hours. After two attempts, it appears that the space agency has begun its Artemis I mission.
After checking whether repairs from previous tests were in good condition, Charlie Blackwell-Thompson (Artemis launch manager) delivered Proceed to officially start loading thrusters On a Space Launch System (SLS) rocket as part of a cryogenic demonstration test.
Started with Storage Operations Liquid Oxygen Transfer Line Cooling of center stage. Therefore, after cooling the liquid oxygen (LOX) lines, the teams gave green light slow fill stage In addition, they would cool the liquid hydrogen (LH2) transfer line, to load the rocket’s central stage.
Once the LOX fill is complete, NASA has moved on to rapid fill operations. When the cooling of LH2 is finished, it is done Start slow filling liquid hydrogen,
The whole process was carried out without any hesitation, but the test started failing at this last stage. According to a NASA statement, “launch controllers have detected” a hydrogen leak umbilical cord in a cavity in the tail service mast”.
The agency explained that the team “let the propellant flow into the rocket while it corrected the problem.” Engineers have now done the quick disconnect or warm up interface where the fuel feed line connects to the SLS and after fixing the problem they put it back and has continued to test successfully.
After doing this, the engineers Engine purge has started Which will start flowing LH2 at low pressure. NASA has reported that, as this is happening, the team continues to monitor the area where the hydrogen leak has been detected.
In addition, the agency claimed that the engineers Engine Bleed Tests Already Completed, which flows into the supercooled LH2. In this way, they have reduced the temperature of the four RS-25 engines to the conditions required for launch.
