The next-generation moon rocket will be tested at the Kennedy Space Center in Florida on April 9.
This is despite the fact that NASA is working to resolve a technical issue.
There were two previous attempts to begin the wet dress rehearsal that were called off due to technical problems.
NASA reported on Thursday that there was an issue with the upper stage engine. Engineers were able to establish normal helium purge, but are still investigating what caused the issue.
The Kennedy Space Center will host a wet dress rehearsal on Saturday and Sunday. Time.
NASA engineers will fill the powerful Space Launch System rocket with fuel and conduct a mock launch.
If all goes to plan, NASA will be able to prepare for the first launch of the SLS rocket in the next couple of months.
In a comprehensive test of its spaceflight systems, the uncrewed Artemis I mission will send the spaceship to fly by the moon. Artemis II will fly the same route but with a crew on board, while Artemis III will put the first woman and first person of color on the lunar surface.
It looks like NASA needs to take a break from the next-generation rocket test. The date for the first test attempt was changed after four lightning strikes hit the launchpad's lightning towers.
