The SpaceX Starship's debut flight launch on April 20, 2023, was both flawless and spectacular. The 394-foot-tall (120-meter) rocket — the biggest and most powerful ever built — fired up its 33 engines and soared into the skies at 9:33 a.m. EDT. The uncrewed spacecraft was expected to complete a 90-minute trip around the Earth before splashing down near Hawaii.
