SpaceX Starship Launch Today: Watch Live as Elon Musk’s Largest Rocket Attempts Historic Orbital Flight

Thousands of spectators and millions of online viewers are counting down to SpaceX’s next Starship flight test, the ninth overall and the most ambitious to date. Liftoff of Super Heavy Booster 14 topped by Ship 35 is targeted for Tuesday, 27 May, at 7:30 p.m. EDT (23:30 UTC) from Pad A at Starbase, Boca Chica, Texas. READY FOR “FLIGHT 9” The Federal Aviation Administration cleared the mission after reviewing data from the fiery Flight 8 breakup in March, paving the way for up to 25 Starship launches per year. SpaceX has swapped in upgraded Raptor 3 engines, reinforced stage-separation hardware and refined software intended to prevent the thrust-vector control fault that doomed the previous attempt. HOW TO WATCH LIVE SpaceX will stream coverage on X (formerly Twitter) and YouTube about 30 minutes before liftoff. Local beach roads and State Highway 4 close four hours early, and the best public viewing spots are Isla Blanca Park on South Padre Island and the Port Isabel Causeway. Mobile carriers report network boosters in place to handle the surge in visitors searching “Starship launch live.” FLIGHT PROFILE • Super Heavy fires all 33 Raptors for ~2 min 45 s before stage separation over the Gulf of Mexico. • Booster 14 performs a partial boost-back and soft splashdown. • Ship 35 re-lights six Raptors to reach ~240 km apogee and nearly orbital velocity, then executes a controlled re-entry and splashdown northwest of Kauai. If the mission meets its full duration of ~90 minutes, it will mark the first time a Starship prototype completes every milestone from ascent to targeted re-entry. WHY IT MATTERS Success would validate the fully reusable architecture Elon Musk says is essential for monthly cargo flights to the Moon under NASA’s Artemis program and eventual crewed missions to Mars. A clean flight would also quiet critics worried about debris fallout that scattered parts across protected wetlands during earlier tests. WEATHER AND TRAFFIC OUTLOOK The 45th Weather Squadron gives a 70 % chance of favorable conditions, with sea-breeze winds the primary concern. Cameron County officials advise arriving before noon; traffic following April’s total solar eclipse suggests the 18-mile stretch from Brownsville to Boca Chica could take three hours at peak flow.
