SpaceX Starship Mega-Launch Today: How to Watch Elon Musk’s Historic Mars Rocket Live

SpaceX is hours away from attempting Starship Flight 14, the most ambitious orbital launch yet for the world’s largest rocket and the first mission expected to generate revenue by deploying a batch of next-generation Starlink V3 satellites. Liftoff from Starbase in Boca Chica, Texas, is targeted for 14:37 UTC today, 28 September 2026, with a 90-minute window. If weather or technical issues intervene, SpaceX has backup opportunities through the week. The Federal Aviation Administration issued the launch license late Sunday after the company closed out environmental and safety reviews, clearing the way for a mission that could redefine low-cost access to orbit. Why Flight 14 matters • First paying payload: Up to 28 Starlink V3 satellites will ride inside Starship’s payload bay, inaugurating a commercial revenue stream for the super-heavy vehicle. The V3 platform offers 2× the bandwidth of V2 minis now launched on Falcon 9, a key step toward SpaceX’s goal of supporting cellular backhaul for partners like T-Mobile and KDDI. • Rapid reusability test: SpaceX will attempt controlled splashdowns for both the 120-meter Starship upper stage and the Super Heavy Booster 12 in the Gulf of Mexico, gathering data to enable future pad landings and same-day reuse. • Bigger payload envelope: A successful flight validates the 250-ton to low-Earth-orbit capacity Musk has promised for lunar cargo missions and NASA’s Artemis crewed lander variant. Live coverage and how to watch SpaceX will stream the countdown and launch on X (formerly Twitter) and YouTube beginning 45 minutes before T-0. Independent feeds from NSF Live and LabPadre will provide additional pad views and commentary. Local authorities advise spectators to stay outside a 4-mile exclusion zone along Texas Highway 4; beach access is closed until 24 hours after launch. Technical upgrades for Flight 14 Since Flight 13’s ascent-stage RUD in July, engineers have strengthened engine shields, added a flame-diverter water deluge system beneath the orbital launch mount, and tweaked guidance software to smooth booster roll during ascent. The Raptor 3.1 engines now feature redesigned injector plates rated for 350 bar chamber pressure, allowing throttle-down to 38 percent for gentler staging. What’s next if Flight 14 succeeds Elon Musk says Flight 15 is already stacked in the mega-bay, poised to send NASA’s CLD-1 demo habitat on a 500-km shakedown orbit in November. Simultaneously, SpaceX hopes to win FAA approval for the first Starship landing on the converted “Chopsticks” tower, eliminating ocean disposal and slashing turnaround time to “hours, not days.” Bottom line Today’s SpaceX Starship Flight 14 is more than another test: it is the moment Starship transitions from experimental prototype to commercial workhorse. Success would not only accelerate NASA’s lunar timetable but also open a high-capacity lane for global broadband and deep-space missions, pushing SpaceX further ahead in the new space race.
