IFT-12 NET Adjusts to May 20 — Starship V3 in T-1 Day Terminal Countdown at Starbase (Artemis II Day 38 Post-Splashdown)

SpaceX's Starship Integrated Flight Test 12 (IFT-12) entered T-1 day terminal countdown operations at Orbital Launch Pad 2 (OLP-2), Starbase, Boca Chica, Texas on May 18, 2026 — with the Net Earliest Timing (NET) window confirmed as May 20, 2026 at 5:30 PM CDT (22:30 UTC), extending through approximately 20:00 ET. The NET was quietly adjusted one day from the previously advertised May 19 window; the updated date appeared on SpaceX's launch schedule by the afternoon of May 17, requiring no formal scrub announcement since the vehicle — Booster 19 and Ship 39 — remained fully healthy and stacked at the pad throughout. On May 18, launch teams conducted final T-1 operations including avionics integrity checks, propellant loading timeline coordination, Eastern Range (Space Force / FAA) safety polling, weather confirmation for the May 20 primary window, and final hold-for-approval reviews. IFT-12 is the maiden flight of the clean-sheet Starship V3 (Block 3) architecture: Booster 19 carries 33 next-generation Raptor 3 engines offering a significant thrust increase over Raptor 2, while Ship 39 is the first Starship to carry a pressurized docking port and propellant-transfer interface hardware mandated by NASA for Artemis III HLS qualification. The payload manifest includes 22 Starlink V3 simulator units and two external cameras to photograph the heat shield during reentry. IFT-12 trajectory: Booster 19 will attempt a Gulf of Mexico water splashdown (no Mechazilla tower catch on this first V3 flight); Ship 39 will fly a suborbital arc to Indian Ocean splashdown, enabling full evaluation of the new docking hardware under simulated space conditions. The Artemis II crew — Commander Reid Wiseman, Pilot Victor Glover, Mission Specialist Christina Koch, and Canadian Mission Specialist Jeremy Hansen (CSA) — continued post-flight physiological reconditioning and mission debriefs at Johnson Space Center, Houston on Day 38 post-splashdown (Orion splashed down April 10, 2026 at 8:07 p.m. EDT). Orion's Avcoat heat shield visual inspection continues at KSC's Multi-Payload Processing Facility; Marshall Space Flight Center X-ray scans and sample extractions remain on track for summer 2026. Artemis III SLS core stage stacking advances in VAB High Bay 2.
