A recent NASA announcement states that the space agency will modify the wet dress rehearsal, and the date on which it will be made is changed, thus creating delays.

Until now, NASA is going to do a wet dress rehearsal test on Tuesday, April 12, 2022 and tanking on Thursday, April 14, 2022. These are the final data announced by NASA after changes and delays lately.

This test is one of the most important final tests of the Artemis I mission.

This can improve countdown procedures and validate critical models and software interfaces, which are important before launch, according to NASA.

The reason for the repeated cancellations for this test arose after engineers from the Artemis I mission identified a helium check valve that was not working as originally thought.

Following the modified test, NASA has decided that the Space Launch System rocket and the Orion spacecraft will return to the General Vehicle Building (VAB), in the hope that engineers will be able to replace the valve (if necessary).

NASA will launch the mission in May. More news coming soon.
