CRS-34 Cargo Dragon Scrubbed Due to Weather on May 12 — Rescheduled to May 13 at 6:50 p.m. EDT

SpaceX's CRS-34 Cargo Dragon mission to the International Space Station was scrubbed on May 12, 2026, due to poor weather conditions at Cape Canaveral Space Force Station. The mission had been targeting a 7:16 p.m. EDT liftoff from Space Launch Complex 40 (SLC-40). Weather constraints — including concerns over anvil clouds and lightning within the flight path — forced the launch team to stand down for the day. The backup window was immediately retargeted for May 13, 2026, at 6:50 p.m. EDT (22:50 UTC). CRS-34 will fly aboard Falcon 9 booster B1096 on its 6th flight, with Dragon capsule C209 carrying approximately 6,500 pounds (2,950 kg) of science experiments, crew supplies, and hardware for the ISS crew. The booster will target a Return-to-Launch-Site landing at Landing Zone 40 (LZ-40), the newest SpaceX recovery pad adjacent to SLC-40. Dragon docking with the Harmony module's forward port is now planned for May 14 at approximately 7:35 a.m. EDT. The scrub also eliminated the possibility of SpaceX's first-ever simultaneous dual-launch day that had been envisioned when IFT-12 appeared set for May 12 — though IFT-12 itself was delayed to May 19.
