SpaceX launched 26 Starlink satellites from California on Monday evening (June 16). A relatively new Falcon 9 rocket, making only its third flight, lifted off at 8:36 p.m. PDT local (11:36 p.m. EDT or 0336 GMT June 17) from Space Launch Complex 4 East at Vandenberg Space Force Base.

SpaceX states that its Falcon 9 rocket will send up Starlink 12-26 mission from Space Launch Complex 40 at Cape Canaveral Space Force Station at 11:21 a.m. ET. The launch window will open from 11:21 a.m. ET until 11:44 a.m. ET, meaning SpaceX has during that timeframe to launch its rocket.
