Falcon 9 (B1090, 12th Flight) Launches Starlink 10-43 from Cape Canaveral — 70th Orbital Mission of 2026; ASOG 153rd Recovery

SpaceX Falcon 9 booster B1090 (12th flight) lifted off from Space Launch Complex 40 (SLC-40) at Cape Canaveral Space Force Station at 6:26 a.m. EDT (10:26 UTC) on June 4, 2026, carrying 29 broadband Starlink V2 Mini Optimized satellites to low Earth orbit. The first stage performed a downrange burn and landed on the autonomous spaceport drone ship 'A Shortfall of Gravitas' (ASOG) in the Atlantic Ocean — ASOG's 153rd booster landing and the 621st cumulative SpaceX booster recovery. B1090 previously flew NASA Crew-10, CRS-33, and the Bandwagon-3 rideshare mission. The June 3 Vandenberg and June 4 Cape Canaveral launches deployed 53 Starlink satellites within approximately 19 hours from opposite U.S. coasts, demonstrating SpaceX's parallel two-pad-coast launch cadence. This is SpaceX's 70th orbital mission of 2026. June 4 marks the first day of SpaceX's historic IPO management roadshow (June 4–8), with the company simultaneously launching its 70th orbital mission and its investor roadshow in the same morning window. The Starlink active constellation now exceeds approximately 10,611 satellites in orbit.
