SpaceX Found Something Weird in Starship Booster’s 33-Engine Static Fire test…No Launch in May!?

Welcome back to another high-energy installment of Great SpaceX. I'm your host Kevin and today we're waking up to a world that feels a bit louder and much more exciting with massive updates straight from South Texas. Intensive testing is underway and hardware is flying through production at a pace that keeps us on the edge of our seats. I know I am. I'm practically falling off. We've seen the vehicle arrive at the bay standing tall for its next phase but one question hangs in the air. Shall we go now? Even at these final stages the answer remains uncertain. The atmosphere at Starbase is electric yet thick with caution as SpaceX pushes the limits of physics. They've discovered something in the booster tests we haven't seen before. A new variable in the orbital equation. If we have to head back to the drawing board for more testing is a main launch still on the table. What really happened during those fiery moments on the pad? Let's find out on today's episode of Great SpaceX. SpaceX certainly gave us a strong April providing some of the most spectacular visuals we've seen in the history of the Starship program. We witnessed the full engine static fire tests of both Starship stages with plumes of fire and clouds of dust that seemed to signal a clear path forward. But perhaps the impressive results and the smooth rolls that followed those tests led most of us to overlook the underlying problems. It's easy to get caught up in the glory of a successful looking ignition but the reality on the ground is often much more nuanced. Well as it turns out the booster static fire test wasn't actually that smooth. This was revealed in a fascinating 25-minute video that SpaceX released on April 24th which pulled back the curtain on the internal operations of the launch site. An overview of the test management team's work for the two recent tests was released and in a move of remarkable transparency they acknowledged the issues that were hiding just beneath the surface of those flashy livestream clips. To understand where we are going we have to look closely at where things stuttered. Let's start with the first 33 engine test. The one that everyone thought was the big home run. The visual of all those Raptor engines firing in unison was enough to make anyone believe we were ready for liftoff. However the mood in the control room was far more tense than the public realized. Immediately after the test scene the audio from the mission control center tells a different story. A male employee said, We kicked out early all teams triage alerts prepare for offload. Shortly after a female employee provided more context on what went wrong during that attempt saying, Today we aborted our second attempt of the B-19 full count static fire. We actually had another pad abort on the diverter. We made it through engine startup and then ultimately lost some of our sensors on one of the ramp manifolds. It basically said that the manifold pressure was lower than we believe that it probably was and it kicked us out at T plus 1.88 seconds. She went on to clarify the difficulty of simulating these conditions noting, It's just tough because there are some things that are hard to test ahead of time. So the diverter you can test as much as you want but you can't obviously test for what theoretical vibe and environment you're going to see when the engines are turned on. Despite the early shutdown the team is keeping a positive outlook. That same employee expressed her optimism by saying, I think every test is always a success and we had a bunch of findings on the ground systems the vehicle and the engines that I think were really good to flag at this point but definitely a bittersweet day. This mindset of constant improvement was summed up perfectly by a male employee who concluded, We have a saying called only the paranoid survive. The idea behind it is that there's an enormous amount of information and data that's coming to you and if you can use that wisely you can usually use that to figure out where things are going to go wrong in the future. I mean almost every time that we fail something or have something go awry there were clues in previous data in previous operations that if you had known what to look for and been good enough and paranoid enough to do so could have found it there. These updates show us that the test hit snags in several areas, specifically with the flame trench. This was a major upgrade for Pad 2 designed to redirect heat and pressure flow outward. It's a convenient setup but the SpaceX team seemingly underestimated the raw power of 33 Raptor 3 engines. While the flame trench itself stayed stable, the sensors on one of the manifolds failed after the engines roared to life. This caused a perceived pressure drop that forced the system to halt the test at less than 2 seconds in. It just goes to show you can't predict everything, especially when dealing with the theoretical vibes of a rocket launch. There's also the matter of the engines themselves. Musk hinted that the 33 engine test might not have reached its full expected power, suggesting the system is not yet as reliable as we hope. In the video, a female employee mentioned the fallout of these tests, saying, For SpaceX, this is all part of the process. They would rather find the problem now than risk a catastrophic failure during a launch. However, this means a repeat of the 33 engine test is likely, which puts the main launch date for Flight 12 in serious doubt. If a new static fire happens in early May, these subsequent checks could push the actual flight to the end of the month at the very earliest. This 33 engine hiccup followed an earlier failure with B-19 during a 10 engine test. In that instance, the engines themselves seemed to be the primary culprits. Immediately after activation, the system called for an abort. The team recorded the following, Another employee explained the situation, saying, We successfully lit all 10 engines. They were ramping up to power. Everything was looking good, stage and engines combined. However, there was a TAD side abort called. So what that means is some sort of sensor tripped. And from there, we command a fast shutdown. That fast shutdown actually caused more harm than good. One employee noted, We saw some data right after static fire that showed about half the engines had what looked like mechanical damage basically as a result of the really fast shutdown. So we brought the booster back to Megabay. We then decided to remove all 10 engines from the booster so that we could troubleshoot and understand what's going on those 10 while still making progress on B-19 by backfilling engines from B-20. This shows the sheer logistical effort required at Starbase. They aren't just fixing a rocket. They are managing a rotating inventory of parts. This time, it seems, the problem came from the engines censored, causing the quick shutdown command to be activated. Surprisingly, the failure rate was quite high, with about half of the 10 engines failing due to the rapid shutdown command. As a result, SpaceX had to replace all 10 engines entirely. These 10 engines will enter the analysis and improvement phase, while new engines have been delivered from the B-20 inventory. These are likely the very 33 engines that were tested afterward. Overall, this testing campaign continues to show that SpaceX still has a lot of work to do with the Raptor 3. It looks really cool, and it's also showed great power in both the booster and ship tests, but behind that impressive display, there's still significant issues that could prevent us from moving on to Flight 12. For many, this is certainly a disappointment, especially considering the long list of tasks to be done after Flight 12. But for others who share the same paranoid view as the SpaceX employees, this is a necessary precaution toward long-term success. Clearly, if SpaceX delays further, we'll have to start worrying about their future and how they fit into the broader space exploration timeline. 2026 is a crucial year of preparation before the lunar missions are scheduled to arrive in mid-2027. On the road to that deadline, SpaceX must accomplish many goals for Starship. The upcoming Flight 12 will be the mission to demonstrate the V3 upgrades. These changes are not just cosmetic, they include the engines, heat shield piping, grid fins, and more. SpaceX has been showcasing these upgrades for a long time since the previous version was still operational, and they have raised expectations for improving Starship's capabilities. This version of the ship is the one that needs to prove the architecture is viable for mass production and rapid reuse. It also puts a lot of pressure on the program. While previous versions allowed for mistakes to be corrected and learned from, V3 is perhaps the point where Starship must succeed to achieve its broader goals. Flight 12, as the first first flight of this version, will have to succeed in unlocking everything that comes next. Next on the list is Flight 13, which has been implicitly confirmed to be Starship's first time in orbit. This will be a massive milestone, showing that Starship has met the required standards for the space rocket industry. This milestone will also mark the phase where Starship will begin contributing to the construction of space systems, such as deploying payloads, launching satellites, or building the critical refueling systems. Once launched into orbit, it'll have to return. And Flight 14 could be the flight where Starship will return for a two-stage landing using the Mechazilla arms, thereby completing the dream of full reusability. This milestone marks Starship reaching a new, unprecedented level in the industry, making traditional rockets look like ancient history. These will be the goals towards Starship's fundamental capabilities. Only when they are achieved and mastered will Starship truly be ready for the lunar missions. Meanwhile, the task of building the refueling system will take place afterward, but its deadline will likely be pushed back to 2028. Overall, quite a few goals need to be accomplished in a very short amount of time. They are all challenging, and no one knows if SpaceX can achieve 100% success at each step. Therefore, SpaceX is facing pressure from two sides. The internal need to launch quickly to meet NASA's deadlines, and the external need to succeed in every flight to avoid massive delays at each stage. And as Flight 12 progresses further into the year, the time pressure will only increase. In that situation, SpaceX will need to remain calm and make truly intelligent decisions to achieve rapid and sustainable success. They have to balance the urge to fly with the necessity of being paranoid about their data. All that leads us to a very clear conclusion. Starship's journey has never been a straight line. It's not a simple path from A to B. It's a series of advances, followed by retreats, and then even larger advances again. Each problem exposed isn't a sign of failure, but a necessary price to pay for a system reliable enough for larger missions that will carry humans. If viewed that way, what's happening at Starbase right now isn't dimming SpaceX's future, but rather shaping it more clearly. Flight 12 might not take off in May after SpaceX's revelations. It might not even launch until the summer. But what really matters isn't when it launches. It's about what it achieves when it finally clears the tower. Because with just one successful flight of the V3 architecture, the entire chain of goals behind it, from orbit and complete reusability to lunar missions, will be immediately unlocked. And then all the previous delays will almost certainly become worthwhile. We'll look back at these sensor failures and manifold issues as the growing pains of a new era. That brings us to the end of today's episode. I want to thank you all for being part of this journey with us. Your support and your comments keep the energy high here at the channel.
