JAKARTA - The launch of Artemis II, which is scheduled for March, could be delayed. This happened because of a glitch that NASA technicians found in the Space Launch System (SLS) rocket.
According to NASA's latest report, technicians detected a disturbance in the helium flow in the SLS rocket propulsion stage. Now, NASA is preparing to move the SLS rocket and the Orion spacecraft back to the Vehicle Assembly Building (VAB).
The disturbance was first detected on February 21 after a series of wet test exercises were completed. The technical team is now working quickly to review the data to determine whether repairs can be made on the launch pad or must be in the building.
Helium is a crucial component for maintaining the engine environment and providing pressure to the hydrogen fuel tank and liquid oxygen. Although the system worked during the exercise, the gas flow did not run normally during the post-test reconfiguration.

Currently, operators are using a backup method to ensure the rocket and upper stage engines remain in a safe configuration. NASA is also making emergency preparations to remove the access platform to avoid the risk of high winds that are expected to occur.
Technicians suspected a problem with the upper stage valve, a filter, or the ground-side interface that connects the rocket to the fueling system. They reviewed Artemis I mission data to see if there were any similarities in the actual helium pressure problem patterns that had occurred.
If the repair process takes a long time, NASA is certain to miss the launch window scheduled for March. This launch decision will depend heavily on the results of data findings and technical repair efforts.
