SpaceX’s Starship rocket has blasted off on another test flight, this time carrying 20 of the most advanced Starlinks. Towering more than 400 feet, Starship soared from Texas on Friday, a week after a last-second launch abort. It’s the 13th flight of the world’s biggest and most powerful rocket. Like the May demo, neither the booster nor spacecraft is being saved, instead ditching into the sea. NASA is counting on Starship as a lunar lander for the Artemis moon program. NASA needs Starship to wrap up testing and reach orbit soon so the Artemis III astronauts can practice next year.
