SpaceX has pulled off the boldest test flight yet of its enormous Starship rocket. Elon Musk's company caught the returning booster back at the Texas launch pad with mechanical arms Sunday, shortly after liftoff. Towering almost 400 feet, the empty Starship blasted off from the southern tip of Texas. It arced over the Gulf of Mexico like the four Starships before it that ended up being destroyed. This latest demo successfully brought the first-stage booster back to land seven minutes after liftoff. The launch tower has monstrous metal arms, dubbed chopsticks, that caught the descending 232-foot booster. The spacecraft it launched splashed into the Indian Ocean, precisely as planned.
