SpaceX’s mega Starship rocket blasted off from Texas on Thursday, the fourth test flight for the spaceship that NASA and Elon Musk are counting on to get humanity to the moon and Mars.
The world’s largest and most powerful rocket — almost 400 feet (121 meters) tall — was empty as it soared above the Gulf of Mexico and headed east. The spacecraft on top was aiming for a half-lap around the planet with a splashdown in the Indian Ocean, once it ditched the first-stage booster in the gulf.
