Artemis-1: NASA technicians replaced the faulty seal that caused the hydrogen leak

Artemis-1 is always stopped. If the NASA does not yet dare to advance a next test date for its launcher SLS (Space Launch System), at least his technicians have made good progress on the necessary repairs. The defective seal – at the origin of the big hydrogen leak which had occurred during the filling of the tanks – was able to be replaced on Friday September 9, which was obviously not a sinecure knowing that the leak zone was no less than 20 cm wide. As a reminder, the leak at this joint had led to the cancellation of the launch barely a few tens of minutes before the countdown. Cautious, the NASA technicians also replaced another joint over a width of nearly 10 cm at the very place where a first leak had declared itself on August 29.

Now that the potential breaches have been closed, NASA should now proceed with fueling tests under launch conditions. A first test would be scheduled for September 17, and there would still be no question of launching the rocket (just filling the tanks). On the other hand, the filling phase would be complete, with no less than 2.7 million liters of hydrogen and liquid oxygen spilled inside the SLS. Once this test is successful (fingers crossed), NASA will then move on to the engine cooling test, then to the self-destruct system test (which could exceptionally be carried out on the launch pad rather than in the hangar). Suffice to say that we are not about to see the SLS heading for the Moon…
