SpaceX is preparing to launch the 12th test flight of its Starship megarocket, designated Version 3 (V3), at 6:30 p.m. ET. This mission is significant as it marks the first flight of the upgraded vehicle after the challenges faced with the previous Version 2 prototype. The company aims to hit several key milestones during the flight, including the deployment of 22 simulator satellites and testing new technologies designed to enhance the rocket's performance and recovery capabilities. Notably, the V3 features redesigned gridfins that are larger and stronger, a new propulsion system, and improved thermal protection mechanisms. CEO Elon Musk has stated that achieving operational readiness for Starship is crucial for NASA's plans to land astronauts on the Moon by 2028. Although SpaceX is optimistic about the upgrades, it has tempered expectations for the test flight, acknowledging that it may not go perfectly. The Super Heavy booster will be discarded in the ocean, but the company aims to simulate a controlled landing to prepare for future recovery attempts. This test is part of SpaceX's broader goal to establish a robust space transportation system for deep space exploration.
