SpaceX’s Massey’s Test Site is a private vehicle test facility at the end of Massey Way, distinct from Starbase’s production and launch facilities. It supports cryogenic proof, structural, and Starship static-fire testing. The site is not a general visitor attraction: the U.S. Coast Guard has documented recurring tests and temporary safety zones on nearby Rio Grande waters during explosive operations, with entry requiring Captain of the Port authorization when enforced. Check current Coast Guard notices and local access controls before approaching.
