In Science and Space: NASA’s Artemis 1 lunar booster passed a critical refueling test on Wednesday, September 21, which could keep it on track for a scheduled takeoff on May 27. 9.
The Artemis 1 team replaced the two gaskets around the quick disconnect on September 9, then scheduled a refueling test to see if the fix worked. This test took place Wednesday on Launch Pad 39B at NASA’s Kennedy Space Center (KSC) in Florida, and it brings good news for the mission.
Artemis 1 will put an unmanned Orion capsule into lunar orbit using a giant Space Launch System (SLS) rocket. NASA attempted to launch the mission on September 1. 3 but was hampered by a liquid hydrogen fuel leak during the “quick disconnection” in the core stage of the SLS, an interface that connects the rocket to the fuel path from its mobile launch tower.
“All the goals that we set for ourselves, we were able to accomplish today,” Artemis launch director Charlie Blackwell-Thompson, of KSC’s Exploration Ground Systems program, said. know in a brief comment after Wednesday’s test, which took up most of the time. daytime. This doesn’t mean everything goes perfectly. For example, a leak at a quick disconnect reappears when liquid hydrogen is loaded. But the team fixed it; they heat up the quick disconnect, allowing it to “reinstall”, which reduces the leak rate to an acceptable level.
