Starship V3 Engine Failures Confirmed: What Actually Went Wrong on Flight 12

Starship V3 Engine Failures Confirmed: What Actually Went Wrong on Flight 12
SpaceX's V3 Starship completed its debut test flight Friday, but engine failures on BOTH stages were more extensive than initial coverage suggested. The mission succeeded enough to matter — but the hardware problems deserve a harder look than the celebration headlines are giving them.

The Celebration Was Real. So Were the Failures.

Flight 12 landed in the Indian Ocean. Satellites deployed. Elon Musk posted 'epic' on X. NASA Administrator Jared Isaacman flew to Texas and declared Starship 'one step closer to the moon.'

All true. But the cheerleading coverage soft-pedaled what went wrong.

Two Stages. Two Engine Problems.

This wasn't a minor hiccup on one system — it was engine failures across both the booster and the spacecraft.

On the Super Heavy booster, one of the 33 Raptor 3 engines shut down early during the climb. Then, during the attempted return-to-splashdown burn, multiple additional engines failed to fire, according to CBS News. The booster missed its planned splashdown point off the Texas Gulf Coast entirely.

On the Starship upper stage, one of the six third-generation Raptor engines — specifically one of the three optimized for vacuum operation — shut down early during the climb to space. That forced the flight computer to run the remaining five engines longer than planned just to stay on an acceptable trajectory, according to CBS News.

The trajectory stayed 'within bounds' — SpaceX's term. But the engine failure prevented an attempted engine relight in space ahead of splashdown, according to CNN. And during the actual landing burn, only two of three intended engines fired.

The ship still landed controlled. But running on degraded systems for the majority of the flight is not a minor footnote.

What the Headlines Got Wrong

AP News and NPR both led with 'biggest, most beefed-up Starship yet' framing — technically accurate, editorially incomplete. The scale of the engine failures got buried.

NPR mentioned engine trouble in passing. AP mentioned 'some engine trouble.' CBS News gave the most detailed breakdown. CNN's live blog was the most technically honest, spelling out specifically which burns failed and why they mattered.

The obvious question went unasked: If this is the rocket NASA is counting on to land astronauts on the moon by 2028, why are engines shutting down on both stages during the very first V3 test flight?

The Numbers That Actually Matter

Starship V3 stands 407 feet tall — eclipsing previous versions by several feet, according to NPR. It generates 18 million pounds of thrust at liftoff, twice the power of NASA's SLS moon rocket, according to CBS News.

This was the 12th overall test flight of the Starship program. The last flight was in October 2025 — a seven-month gap while SpaceX dealt with the V2 explosion problems.

The V3 launched from a brand-new launch pad at Starbase near the Texas-Mexico border. A pad issue scrubbed Thursday evening's attempt with under a minute on the clock.

The deployed payload: 22 mock Starlink satellite simulators — CBS News says 22, NPR says 20. Two of those simulators carried cameras that sent back footage of Starship's heat shield from outside the vehicle — a genuine first, and genuinely useful for future flights.

The IPO Elephant in the Room

This launch happened two days after Musk announced SpaceX is going public, according to NPR.

SpaceX is heading toward what CNN called a 'record-shattering IPO.' The company needs Starship looking like a success story, not a development program with persistent engine reliability problems. The connection between the timing and the coverage is worth noting.

What SpaceX Actually Needs to Prove

The moon mission timeline is 2028. That's less than two years away. NASA's Artemis program is depending on Starship to land astronauts — actual human beings — on the lunar surface.

Engine shutdowns on a test flight are expected. SpaceX said so explicitly. The program has 'multiple test flights' ahead, according to CBS News.

You cannot have engines failing on both stages during a crewed lunar landing attempt. The margin for error goes to zero when there are people on board.

Flight 12 showed the V3 airframe can survive its own trajectory. It showed the heat shield held. It showed deployment works. These are real wins.

It also showed Raptor 3 engines — the newest, most powerful version — are not yet reliable enough to fire consistently when commanded.

That's the story. Not the celebration. Not the IPO. The engines.

What Comes Next

Flight 12 was a success by test-flight standards — and a clear warning sign for operational reliability. SpaceX has work to do on Raptor 3 before any human being climbs aboard.
