Frustrated again, NASA delayed the second hot test of SLS rocket

On February 25, NASA delayed the second hot test of the core stage of the new rocket space launch system (SLS) due to the abnormal operation of a valve.

For several months, NASA staff have been testing the SLS core. The tests will be carried out at NASA Stannis Space Center in Mississippi, and will be sent to Florida after completion. Artemis 1 will be launched into space at NASA Kennedy Space Center near Orlando.

The agency confirmed that in the first hot test run on January 16, the problem valve worked normally. But the whole process lasted only 67 seconds, far from the original 8 minutes, so NASA arranged a second hot test to collect all the necessary data to ensure the normal operation of the rocket.

In recent weeks, however, there have been signs that 2024 may not be the deadline for NASA to complete its manned mission to the moon. Earlier this month, the Biden administration promised to continue to work on the human landing on the moon, but the goal of completing the mission by 2024 was not mentioned in the discussion.
