A pair of Falcon 9 rockets lifted off within hours of each other on missions to expand the private spaceflight company's broadband internet relay megaconstellation. The flights, which left their launch pads at 11:40 a.m. EDT (1540 GMT) on Wednesday (June 3) and 6:26 a.m. EDT (1026 GMT) on Thursday (June 4), carried 24 and 29 satellites, respectively.
The first mission, carrying Starlink batch 17-47 on the Falcon 9 booster B1088, departed from Space Launch Complex 4 East at Vandenberg Space Force Base in California. The second, with group 10-43 on B1090, left Space Launch Complex 40 at Cape Canaveral Space Force Station in Florida.
