SpaceX canceled the maiden launch of its Starship V3 rocket at Starbase, Texas, due to a hydraulic arm issue. The countdown was halted just 40 seconds before liftoff when the hydraulic pin securing the launch tower arm failed to retract. Elon Musk announced that if the problem is resolved, a new launch attempt is scheduled for 5:30 p.m. local time on Friday. This mission marks the 12th flight of the Starship program and the first since October 2025. The V3 version features significant upgrades, including a redesigned Raptor engine and modifications to improve reliability and reusability. Despite the cancellation, SpaceX plans to continue testing, with the booster and spacecraft performing soft landings at sea. The launch comes as SpaceX prepares for an IPO, with the success of the Starship program being crucial for future growth. Starlink, a SpaceX subsidiary, reported $11 billion in revenue last year, highlighting the importance of Starship's development for deploying next-generation satellites.
