The Elon Musk-led company is now hard at work to stop the next prototype, [dubbed SN11](), from blasting itself into [tiny bits of steel shrapnel](). That means that the big question in the space industry is whether it'll succeed — a tension that, naturally, seems to be top-of-mind for Musk himself. ## Sloshing Helium Musk took to Twitter on Tuesday to explain what may have gone wrong during SN10's maiden voyage last month. "SN10 engine was low on thrust due (probably) to partial helium ingestion from fuel header tank," the billionaire explained. "Impact of 10m/s crushed legs & part of skirt." The next prototype could have some sturdier legs to make sure the ground doesn't cause any damage to the fuel tanks above. "Multiple fixes in work for SN11," Musk promised in the tweet. ## Sucking Bubbles When asked if there were any baffles, which are devices used to restrain a liquid fluid or gas, in place to keep the rocket fuel from sloshing around, Musk [made an educated guess]() — and elaborated on what may have caused SN10 to blow up. "There were baffles, but one may have acted like a straw to suck bubbles in from above liquid/gas level." Musk spoke from experience. "Something similar happened on an early Falcon 1 flight, resulting in unexpectedly high liquid oxygen residuals at main engine cutoff," he added. SN11 has already been [rolled onto the launch pad](), where it's awaiting its first static fire tests. SpaceX has a decent chance of both landing it — and not have another massive explosion on its hands. If it does explode, there will be plenty of future prototypes to iron out the kinks. Keen eyed onlookers have [already spotted leg skirts]() for a prototype called SN20. **READ MORE:** [Elon Musk Explains Why the Starship SN10 Prototype Exploded After Landing]() \[*Gizmodo*\] **More on Starship:** *[SpaceX Just Rolled Its Next Starship Prototype Onto the Pad]()* ## Author I've been at Futurism since 2017, where my role has evolved to encompass design, writing, and increasingly editing. I've always been fascinated by space exploration and advanced transportation, which I've leaned into by interviewing luminaries in those fields while closely following the dimensions of policy and regulation that allow next-generation projects to succeed -- or, sometimes, to fail. I'm also keenly interested in the effects of generative AI on society, policies, and democratic institutions, as well as clean energy, physics and biology, and the vagaries of tech leadership. My work for Futurism has been cited by publications including Ars Technica, Gizmodo, PC Magazine, Jalopnik, Fox News, and the New York Post. I spent my childhood living in locations including Manila, the Philippines, and Geneva, Switzerland, attended McGill University, and now live in Toronto, Canada. Before Futurism I worked at AskMen and a small photography studio. In my free time, I'm an avid gardener, foodie, and craft beer lover, as well as a maker of artisanal hot pepper sauces. I have a magnificent dog named Freida. ### Author social links [Bluesky]()
