NASA - ARTEMIS-1 Mission patch.
May 23, 2022
The Space Launch System (SLS) rocket and Orion spacecraft are slated to return to launch pad 39B at NASA’s Kennedy Space Center in Florida in early June for the next wet dress rehearsal attempt.

Engineers successfully completed work on a number of items observed during the previous wet dress rehearsal test. This includes addressing the liquid hydrogen system leak at the tail service mast umbilical, replacing the interim cryogenic propulsion stage (ICPS) gaseous helium system check valve and support hardware, modifying the ICPS umbilical purge boots, and confirming there are no impacts to Orion as a result of storms and subsequent water intrusion at the launch pad. The team also updated software to address issues encountered during core stage tanking of liquid hydrogen and liquid oxygen during previous rehearsal attempts.
The purge boots are not flight hardware, but enclose an area around the ICPS umbilical – the connection between the mobile launcher and the upper stage – to protect it from the natural environment during propellant loading.
Meanwhile the contractor for gaseous nitrogen has completed their repairs to the distribution system that will be used to support the Artemis testing and launch campaign. The repairs and tests ensured the system is ready to support tanking operations. During wet dress rehearsal and launch, teams use gaseous nitrogen to purge the rocket including its umbilical plates and to support other operations.
Engineers also are completing some of the forward work originally scheduled to take place in the Vehicle Assembly Building (VAB) after wet dress rehearsal. This includes opening the Orion crew module hatch and installing some payloads, such as hardware elements for the Callisto technology demonstration, a flight kit locker, and container assemblies for a space biology experiment.
Following completion of a few remaining verifications, teams will retract platforms inside the VAB to prepare SLS and Orion to roll out to pad 39B. Plans call for the next wet dress rehearsal to take place about 14 days after the rocket arrives at the pad.
