SpaceX launched its fifth test flight of the Starship rocket on Sunday, successfully catching the 20-story Super Heavy booster for the first time. The booster returned to SpaceX’s launch tower in Texas just seven minutes after liftoff, marking a breakthrough in the company's goal of developing a fully reusable rocket system. The rocket’s booster was caught by the tower’s “chopstick” arms, a feat SpaceX engineers have been preparing for years. Starship continued its journey and splashed down in the Indian Ocean after traveling halfway around the Earth.
