SpaceX's latest attempt to launch its 407-foot (124-meter) Starship rocket encountered significant last-minute problems, halting the countdown just 30 seconds before liftoff. The rocket was set to embark on a test flight from Texas, aiming to travel halfway around the world and release 20 mock Starlink satellites before its controlled descent into the Indian Ocean. However, complications arose at the launch pad at Starbase, located near the Mexican border. CEO Elon Musk later revealed that a hydraulic pin, which secures the launch tower's arm, failed to retract, leading to the countdown's termination. Musk expressed optimism that the issue could be resolved quickly, potentially allowing for another launch attempt as soon as Friday. This test flight is particularly significant as it represents the 12th test of the Starship program and is the first since last fall. NASA is depending on this upgraded version of Starship to facilitate future lunar landings, highlighting the rocket's importance in upcoming space exploration initiatives.
