SpaceX launched its sixth Starship test flight on Tuesday, advancing the development of the massive rocket system. The uncrewed flight took off from Starbase in Texas, reached space, and splashed down in the Indian Ocean. The Super Heavy booster splashed down in the Gulf of Mexico after not meeting the criteria for a landing attempt. The test flight included new trials, such as reigniting an engine in space and enhanced heatshield tests. President-elect Donald Trump attended the launch, highlighting his connection with CEO Elon Musk. Starship, the tallest and most powerful rocket ever launched, is critical to NASA's Artemis program and aims to revolutionize space transport.
