🚨 Artemis II Update🚨 — 2nd Wet Dress Rehearsal Confirmed For Thursday February 19th NASA has announced the second Wet Dress Rehearsal (WDR) of the Space Launch System for Artemis II will begin on Tuesday Feb 17th, with a simulated T-0 of 8:30pm EST on Thursday Feb 19th. 🕒 Launch Controllers Call To Stations : 6:40 PM EST (Feb 17th) 🎯 Simulated T-0 : 8:30 PM EST (Feb 19th) with 4 hour window During the test, teams will run two “terminal count” simulations — pausing at T-1:30 and again near T-33 seconds, then recycling the clock back to T-10 minutes to simulate a real launch scrub scenario. Although the Artemis II astronauts won’t participate, pad crews will rehearse Orion hatch closeout operations just like on launch day. The rehearsal will be a full launch simulation, including: • Loading super-cold cryogenic propellants into SLS • Running the full launch countdown • Practicing countdown holds & scrubs • Recycling the clock and draining the tanks Following last week’s partial fueling test, teams replaced a ground support equipment filter that had restricted liquid hydrogen flow. The line has now been reconnected and engineers are restoring proper environmental conditions at the pad.
