A SpaceX Starship rocket on Wednesday exploded at the Starbase facility in Texas during routine testing in preparation for a launch flight, according to local authorities and live stream footage. The rocket "experienced a major anomaly while on a test stand at Starbase" at 11 p.m. local time, SpaceX said on social media, noting "a safety clear area around the site was maintained throughout the operation and all personnel are safe and accounted for." It's been a tempestuous ride for Elon Musk's mammoth Starship, after three flight launch attempts devolved in fiery glory and air-traffic stopping debris this year to date. Notably, the rocket model has taken off successfully in previous instances, but its vast scale " standing 120 meters (394 feet) tall when factoring in the Super Heavy booster " has raised concerns over its overall reliability and requirements for orbital refueling once in flight.
