SpaceX is racing against time to launch Flight 12, but a recent anomaly with Booster 18 has thrown a wrench into their plans. Can they recover in time to meet their ambitious goals? Here’s the full story—and it’s more complex than you might think.
Following the unexpected setback with Booster 18, SpaceX is now shifting its focus to Booster 19, the next in line for the Block 3 test tanks. But here’s where it gets tricky: before Flight 12 can take off, there’s a laundry list of milestones to tackle, from constructing a brand-new booster to finalizing the launch pad upgrades. And this is the part most people miss—it’s not just about building; it’s about rigorous testing and ensuring every component is flight-ready.
Let’s rewind to the Booster 18 anomaly. Just over a week ago, during a routine gas system pressure test, something went wrong. This test involves loading gaseous Oxygen, Nitrogen, and possibly Helium to stress-test the main propellant tanks (Composite Overwrapped Pressure Vessels, or COPVs) and actuate valves before introducing cryogenic propellants. The result? A gaping hole in the booster’s side, likely caused by a COPV explosion. Thankfully, no one was injured, and SpaceX quickly secured the site. Since then, crews have been dismantling the booster, removing the Liquid Methane (LCH4) tank, common dome, parts of the Liquid Oxygen tank, and transfer tube. But the work isn’t done—further scrapping will continue post-Thanksgiving, and the thrust sim cryo stand itself needs repairs due to hydraulic damage.
But here’s where it gets controversial: SpaceX is aiming to have Booster 19 ready for testing by December, a timeline that’s never been achieved before. Historically, the fastest turnaround for a booster was three months (Booster 17), and even that didn’t involve the kind of rapid stacking and testing SpaceX is now attempting. Booster 19, as of November 27, has begun stacking in Mega Bay 1, but completing it in just three to four weeks? That’s uncharted territory. Is SpaceX biting off more than it can chew, or will this be a groundbreaking achievement?
Meanwhile, the Starbase team is eyeing December for stacking the next Super Heavy booster, aligning with the test schedule for the first Starship V3 vehicle. Flight 12 is still targeted for Q1 2026, but delays could pile up. For instance, Booster 19 isn’t the only piece of the puzzle. Ship 39, the other half of Flight 12, is fully stacked but can’t undergo cryogenic testing until S39.1—a Block 3 ship aft test article—is cleared from the cryo stand. And S39.1? It’s still undergoing tests, welded to the stand and equipped with a forward section for can crusher testing. This could take weeks, if not months.
Then there’s Pad 2, the final piece of the puzzle. While the ship quick-disconnect arm has been installed, there’s still work to do: an LCH4 pump, a blast door, and 20 hold-down clamp doors are yet to be fitted. Is SpaceX’s timeline realistic, or are they setting themselves up for another delay?
What’s your take? Do you think SpaceX can pull off this unprecedented feat, or are they stretching too far? Let us know in the comments—this is one conversation you won’t want to miss!
