SpaceX's Crucial Part Replacement: The Key to Starship's Success

SpaceX had to replace the actuator on a grid fin of its Starship rocket, causing a delay in the launch. Grid fins are crucial for the rocket's landing, providing better steering during reentry. Originally developed by the Soviet Union, these fins have been instrumental in SpaceX's successful rocket landings. The faulty actuator needed to be replaced to ensure a controlled descent into the ocean during this mission.
