SpaceX's New Launch Date for Starship Flight 12 Revealed after Massive WDR...

SpaceX completed its first full-stack wet dress rehearsal for the Starship Version 3 configuration, loading over 5,000 metric tons of propellant and running an autonomous terminal countdown before a planned abort, which cleared the way for Flight 12 targeting a launch date of NET May 19, 2026. The upcoming flight marks the in-flight debut of the more powerful Raptor 3 engines and a hot-staging ring built directly into Booster 19, followed by a controlled soft splashdown in the Indian Ocean. Ship 39 will perform multiple engine relights in space to gather critical data for orbital refueling and attempt a key Starlink deployment test. Featuring a new reusable tile system and a radical southern "wasp waist" trajectory, the mission's ultimate proof of success hinges on a stable splashdown, which would loudly validate that the Version 3 Starship is on the right path.

• ▶ 0:36 SpaceX completed the first full-stack wet dress rehearsal for the Starship Version 3 configuration on Pad 2, loading over 5,000 metric tons of propellant into the fully stacked Booster 19 and Ship 39 for the first time.
• ▶ 2:37 The terminal countdown ran autonomously with flaps, RCS thrusters, the detonation suppression system, and water deluge all activating as planned — before a planned abort safely shut down the countdown seconds before T0.
• ▶ 4:01 The successful WDR is called the single most important integrated test before launch, and new FAA/USCG notices issued just hours afterward revealed the intended Flight 12 launch schedule.
• ▶ 4:49 Flight 12 is targeting NET May 19, 2026, at 5:30 p.m. CDT, based on airspace and ocean closure notices, with May 21, 2026 as a backup date.
• ▶ 5:03 The host says "all signs point to this week being the one," but notes the date is not yet fully confirmed by SpaceX's official website.
• ▶ 5:12 The host asks viewers to subscribe and turn on notifications, mentioning the channel is close to 150,000 subscribers.

• ▶ 5:42 At T-minus 3 seconds, all 33 Raptor 3 engines on Booster 19 ignite at full throttle, generating over 9,200 tons of thrust for the tallest Starship stack ever — marking the first in-flight debut of the Raptor 3 engine, which is lighter and about 22% more powerful than Raptor 2.

• ▶ 6:40 About 2 minutes 40 seconds after liftoff, hot staging occurs at roughly 70 km altitude: on V3, the hot staging ring is built directly into Booster 19 (no jettison), and the Ship’s six sea-level plus three vacuum Raptor 3 engines ignite while still attached, with the integrated ring protecting the booster’s dome from the plasma.

• ▶ 7:18 Booster 19 flips, performs its boost-back burn, and then attempts a controlled soft splashdown in the Indian Ocean — with no tower catch this time — so SpaceX can fully validate the new hardware; whether it lands gently or produces a “little boom” will reveal key data on Raptor 3’s reliability during descent.

• ▶ 8:38 If Flight 12 nails the Starlink deployment, it's a huge green light for launching real Starlink Version 3 satellites (53 at a time) later this year.
• ▶ 8:46 Ship 39 will perform multiple Raptor 3 engine relights in space, gathering critical data for orbital refueling and the future tanker version of Starship.
• ▶ 10:02 Ship 39 is the first V3 Starship with an entirely new tile system, designed for reusability across multiple re-entries to enable rapid turnaround.
• ▶ 10:42 Flight 12 abandons the old northern trajectory and takes a radical southern route, threading a narrow corridor between Mexico/Cuba and the Caymans/Jamaica.
• ▶ 11:14 This extremely tight "wasp waist" corridor is the heart of the mission, with the key moment being Ship 39's splashdown.
• ▶ 11:20 A stable splashdown—no explosion, tipping, or loss of control—would be the loudest proof that the Version 3 Starship is on the right path.

• ▶ 0:00 Introduction and WDR Success (0:00 - 4:44) - Covers Flight 12 keys, the full-stack wet dress rehearsal on Pad 2, cryogenic visuals, countdown/abort, detanking, and updated launch notices.
• ▶ 4:44 Flight 12 Launch Target and Preview (4:44 - 5:26) - Updated notices point to the launch window and the host asks for channel support before the flight.
• ▶ 5:26 Countdown, Liftoff, and Booster 19 Return (5:26 - 7:46) - Covers countdown, Raptor 3 debut, hot staging, and Booster 19's targeted splashdown.
• ▶ 7:46 Starlink Deployment, Relights, and Re-Entry (7:46 - 10:36) - Ship 39 deploys the mass simulator, performs engine relights, then dives into re-entry with the upgraded V3 heat shield.
• ▶ 10:36 New Trajectory and Splashdown/Catch Outlook (10:36 - 12:16) - Flight 12 uses a new southern route, ending with Ship 39 splashdown and the possibility of a Mechazilla catch.
