Starlink 17-35 Scrubbed at Vandenberg — Booster B1103 Debut Delayed

SpaceX scrubbed the Starlink Group 17-35 launch attempt from SLC-4E at Vandenberg Space Force Base on April 2, 2026, within the 4:03–8:03 p.m. PT window. The mission — carrying 25 Starlink V2 Mini Optimized satellites to sun-synchronous orbit — was to mark the debut flight of new booster B1103, making it a notable first-flight milestone for SpaceX's booster fleet. The scrub continued a string of delays: the mission had previously been targeting March 28, then March 30, then April 1, before slipping to April 2. Booster B1103 is SpaceX's newest Falcon 9 first stage, representing continued fleet expansion to support the ~140-launch 2026 pace forecast by President Gwynne Shotwell. No cause for the scrub was publicly disclosed; new launch attempts were assessed for the following days.
