“SpaceX aborted the launch of its latest Starship test flight July 16 when some of the vehicle’s engines failed to ignite. Starship was scheduled to lift off on the Flight 13 mission from the company’s Starbase, Texas, test site at 6:45 p.m. Eastern. However, the launch was aborted just as Raptor engines in the Super Heavy booster ignited. SpaceX said moments later that it was calling off the launch attempt for the day.” (07/16/26)
