SpaceX has postponed the 12th test flight of its Starship rocket, specifically the redesigned Starship V3, due to an issue with a hydraulic pin that failed to retract. The launch was initially scheduled for 6:30 pm CT on Thursday from SpaceX's Starbase facility in South Texas but was delayed after a series of minute-by-minute setbacks. Elon Musk indicated that if the issue is resolved quickly, another launch attempt could occur on Friday at 5:30 pm CT. Starship V3 is significant as it aims to be fully reusable and is equipped with upgraded Raptor engines that provide significantly more thrust than earlier models. This test flight will also include the deployment of 20 dummy Starlink satellites and will test new hardware designed for future missions to the Moon and Mars. The Starship system, when fully stacked, stands over 400 feet tall and is designed to carry more than 100 metric tonnes to orbit. Following the launch, the Super Heavy booster is expected to attempt a splashdown in the Gulf of Mexico, while Starship will splash down in the Indian Ocean about an hour after liftoff.
