On Thursday, June 19, 2025, at 1:36 PM Central Time, the EPA was notified by the National Response Center of an explosion of a test rocket at the Space X facility in Brownsville, Cameron County, Texas (commonly known as Starbase, Texas). The explosion burned 70 tons of liquid methane, 1200 tons of liquid oxygen, and an unknown amount of hydraulic fuel. The cause of the explosion is unknown at this time and the area has been closed off to ensure safety of the public.
