SpaceX revealed Big Solution on next-gen Starship after Flight 9 explosion
Starship Flight 9 doesn’t exactly seem like a loss, because right after the flight, Elon Musk and SpaceX immediately revealed solutions to the failures of Starship V2. Even more astonishing is that these solutions are now being integrated into the company’s next-generation Starship.
So what are these solutions, and how do they work to fix the previous issues?
Let’s find out in today’s episode of Alpha Tech.
On May 29, Elon Musk delivered a speech inside SpaceX’s massive Starfactory and unveiled all the upgrades coming to the new version of Starship. Clearly, these improvements are intended to help Starship achieve a new milestone on its journey toward fulfilling the Mars ambition.

The first major point discussed was the upgraded Raptor 3 engine. Just before Starship Flight 9, SpaceX had announced:
“Future upgrades to Starship will introduce the Raptor 3 engine, which will include additional reliability improvements to address the failure mechanism.”
Well, this seems to promise innovations we may have never even imagined. Elon Musk appears to have placed great expectations on this new engine, with technical upgrades that he described as “an alien engine” operating at a level of performance never achieved before.
16:52 “So in order to make the engine like that we had to simplify so many parts of the design incorporate secondary fluid circuits and electronics in the structure of the engine itself. U so everything is contained and protected. Uh, it is uh a marvel of engineering frankly.”

Indeed, the Raptor 3 will be integrated into Starship Version 3, bringing significant improvements over the Raptor 2 engine used in Version 2.
Raptor 3 delivers a thrust of 269 tons at a chamber pressure of 350 bar, compared to Raptor 2’s 230 tons (sea-level) and 258 tons (vacuum). By eliminating the need for an engine heat shield, Raptor 3 reduces mass and enhances reliability, allowing minor fuel leaks to dissipate harmlessly into the plasma flow during reentry. Elon Musk highlights Raptor 3’s simplified design, integrating secondary fluid circuits and electronics within the engine structure, which boosts efficiency and reduces potential failure points. These advancements enable a Super Heavy booster with 33 engines to achieve up to 9,000 tons of thrust, minimizing engine-related failures. The lack of a heat shield also simplifies maintenance, supporting rapid reuse, as true to the name “revolutionary engine” for its mass reduction and reliability improvements.
