SpaceX CEO Elon Musk says there was only minor damage  to its Starship rocket booster in an explosion at its Boca Chica, Texas facility on Monday. The base of the rocket was engulfed in flame and smoke during an engine test. “Damage is minor, but booster will be transferred back to the high bay for inspections, returning to the launch stand probably next week,” Musk said in an email to Reuters.
