At approximately 5 p.m. EDT today, the launch team arrived at their stations inside the Launch Control Center at NASA’s Kennedy Space Center in Florida. The countdown will begin 30 minutes later at 5:30 p.m. or L-45 hours, 10 minutes before the initial target T-0 for the wet dress rehearsal test for NASA’s Artemis I …
NASA is planning to proceed with a modified wet dress rehearsal, primarily focused on tanking the core stage, and minimal propellant operations on the interim cryogenic propulsion stage (ICPS) with the ground systems at Kennedy. Due to the changes in loading procedures required for the modified test, wet dress rehearsal testing is slated to resume …
In continued preparations for the Artemis I wet dress rehearsal test, with tanking targeted for Monday, teams encountered an issue maintaining helium purge pressure on the upper stage engine after change-out of a regulator on the mobile launcher. The RL10 engine on the upper stage uses helium to purge the engine and also to activate …
Teams are preparing for the next attempt of the Artemis I wet dress rehearsal, pending range availability and restoration of propellants and gases during the test. Through the past two test runs April 3 and 4, engineers accomplished several test objectives that will prepare the teams and integrated systems for launch: Configuring Launch Pad 39B …
The Artemis I team has ended today’s attempt at the wet dress rehearsal test at 5 p.m. The countdown ended after partially loading liquid oxygen into the Space Launch System core stage tank. This provided the teams a valuable opportunity for training and to make sure modeled loading procedures were accurate. This was the first time using new systems at NASA’s …
The countdown for the wet dress rehearsal has resumed at 10:52 a.m. EDT and clocks have picked back up at T-6 hours, 40 minutes on the clock (L-7 hours, 10 minutes). A new planned T-0 of 6:02 p.m. has been established. An earlier issue with an outage with the vendor of gaseous nitrogen required for tanking preparations has been resolved. Overnight, teams …
At approximately 7:40 a.m. EDT, the mission management team chair gave the “go” to proceed with tanking the rocket for the Artemis I wet dress rehearsal test. Later in the countdown the Launch Director will give the “go” to begin the tanking process. Meteorologists with Space Launch Delta 45 said there were no weather constraints …
NASA is targeting Monday, April 4, to resume the Artemis I wet dress rehearsal test. The test was stopped Sunday, April 3 prior to tanking due to loss of ability to pressurize the mobile launcher using two fans. The fans are needed to provide positive pressure to the enclosed areas within the mobile launcher and …
Teams have decided to scrub tanking operations for the wet dress rehearsal due to loss of ability to pressurize the mobile launcher. The fans are needed to provide positive pressure to the enclosed areas within the mobile launcher and keep out hazardous gases. Technicians are unable to safely proceed with loading the propellants into the …
At approximately 6:45 a.m. EDT, the launch director and mission management team chair gave the “go” to begin tanking the rocket. Meteorologists with Space Launch Delta 45 said there were no weather violations for the test. All elements are powered up and teams have moved the side flame deflectors into position and completed final preparations …
