NASA’s Space Launch System (SLS) rocket and Orion spacecraft will return to Launch Pad 39B at the space agency’s Kennedy Space Center in Florida in early June for its dress rehearsal after three failed attempts. These wetsuit rehearsals are where the space agency “typically refines countdown procedures and validates critical models and software interfaces,” according to NASA. Engineers have addressed many of the issues discovered in previous wetsuit repeat attempts.
Once completed and tested, the SLS will be the most powerful rocket ever built by NASA, destined to herald the next generation of human space exploration.
But the agency was forced to relocate him in April after a hydrogen system leak affected three rehearsal attempts. The rocket is scheduled to launch in June as part of the Artemis Moon mission. But that will only happen if he can complete a full rehearsal of the wet dress first. The wet dress rehearsal includes a series of tests designed to show that the Orion rocket and spacecraft and their ground infrastructure are ready for launch.
NASA began its first attempt on April 1, and it was supposed to be completed within the next 48 hours after loading liquid hydrogen and liquid oxygen propellants into the rocket and some simulated launch countdowns. But the team ran into multiple problems, mostly due to leaks from the hydrogen system, and were forced to relocate the rocket to the massive Vehicle Assembly Building (VAB) after two more failed attempts.
Engineers would also have completed some of the work that was to take place in the VAB after the dress rehearsal. This forward work included opening the Orion crew module hatch and installing some payloads. Payload such as hardware items for Castillo technology demonstration, flight kit locker and container sets for space biology experiment. The next wet dress rehearsal will take place about 14 days after the huge rocket arrives on the launch pad.
