SpaceX Starship Blasts Off In Ninth Test Flight (space.com) 121

SpaceX's Starship Flight 9 successfully launched and reached space -- marking the first reuse of a Super Heavy booster -- but both rocket stages were ultimately lost mid-mission due to a "rapid unscheduled disassembly." SpaceX CEO Elon Musk said in a statement: "Starship made it to the scheduled ship engine cutoff, so big improvement over last flight! Leaks caused loss of main tank pressure during the coast and re-entry phase. Lot of good data to review." Musk said the next three Starship test launches could lift off every three to four weeks in the days ahead. Space.com reports: The mission lifted off from Starbase today at 7:37 p.m. EDT (2337 GMT; 6:37 p.m. local Texas time), sending the 40-story-tall rocket into the Texas sky atop a pillar of flame. It was a milestone launch, marking the first-ever reuse of a Super Heavy booster; this one earned its wings on Flight 7 in January. (SpaceX swapped out just four of its Raptors after that mission, meaning that 29 of the engines that flew today were flight-proven.) "Lessons learned from the first booster refurbishment and subsequent performance in flight will enable faster turnarounds of future reflights as progress is made towards vehicles requiring no hands-on maintenance between launches," the company wrote in a Flight 9 mission preview.

The Super Heavy had a somewhat different job to do today; it conducted a variety of experiments on its way back down to Earth. For example, the booster performed a controlled rather than randomized return flip and hit the atmosphere at a different angle. "By increasing the amount of atmospheric drag on the vehicle, a higher angle of attack can result in a lower descent speed, which in turn requires less propellant for the initial landing burn," SpaceX wrote in the mission preview. "Getting real-world data on how the booster is able to control its flight at this higher angle of attack will contribute to improved performance on future vehicles, including the next generation of Super Heavy." These experiments complicated Super Heavy's flight profile compared to previous missions, making another "chopsticks" catch at Starbase a tougher proposition. So, rather than risk damaging the launch tower and other infrastructure, SpaceX decided to bring the booster back for a "hard splashdown" in the Gulf of Mexico on Flight 9. That was the plan, anyway; Super Heavy didn't quite make it that far. The booster broke apart about 6 minutes and 20 seconds into today's flight, just after beginning its landing burn. "Confirmation that the booster did demise," [Dan Huot, of SpaceX's communications team] said during the Flight 9 webcast. Super Heavy's flight ended "before it was able to get through landing burn," he added.

Ship, by contrast, improved its performance a bit this time around. It reached space today on a suborbital trajectory that took it eastward over the Atlantic Ocean -- the same basic path the vehicle took on the truncated Flight 7 and Flight 8. But Flight 9 got choppy for Ship after that. The vehicle was supposed to deploy eight dummy versions of SpaceX's Starlink satellites about 18.5 minutes after liftoff, which would have been a landmark first for the Starship program. That didn't happen, however; the payload door couldn't open fully, so SpaceX abandoned the deployment try. Then, about 30 minutes after launch, Ship started to tumble, which was the result of a leak in Ship's fuel-tank systems, according to Huot. "A lot of those [tanks] are used for your attitude control," he said. "And so, at this point, we've essentially lost our attitude control with Starship." As a result, SpaceX nixed a plan to relight one of Ship's Raptor engines in space, a test that was supposed to happen about 38 minutes after launch. And the company gave up hope of a soft splashdown for the vehicle, instead becoming resigned to a breakup over the Indian Ocean during Ship's reentry.

The company therefore will not get all the data it wanted about Flight 9. And there was quite a bit to get; for example, SpaceX removed some of Ship's heat-shield tiles to stress-test vulnerable areas, and it also tried out several different tile materials, including one with an active cooling system. But the company plans to bounce back and try again soon, just as it did after Flight 7 and Flight 8.

        Artemis II is not a landing, it's a manned flight to Lunar orbit (similar to Apollo 10). Artemis III is the mission for landing, assuming it still happens.

        Somebody else beat me to the point that Artemis II is sorta a four-person repeat of Apollo 8 (loop around the moon sans lander), and the Artemis III with landing attempt is currently pushed back to 2027 or 2028, but I wanted to toss in a bit more for you and others to consider:

        Elon just tore down the High Bay in Texas (the original hangar for constructing full-height Block I Starships and SuperHeavies) and is clearing the ground to put up a so-called "gigabay" building right next to (or attached to) the brand new MASSIVE factory there which is still not fully up-and-running. At the same time, he's doing the foundations for another gigabay and setting up a factory at KSC in Florida. This means that unlike a traditional rocket company (like Boeing building an SLS launch vehicle) he will NOT be spending YEARS hand-building each individual rocket. Musk's SuperHeavy+Starship rockets are going to begin pouring out of the factories at an insane rate.

        Elon also is completing construction of the second launch pad in Texas, and his team is prepping another pad in Florida at KSC (the tower is already up and they're building the flame trench and launch platform), with environmental studies underway for (apparently) two more pads in Florida. If the new pads workout, he'll presumably update the initial Texas pad (which needs a lot of work between flights) to the new design and those pads will be able to launch, catch, and re-launch rockets without refurbishment between operations (a world first for heavy lift rocketry).

        What this means is potentially test flights every week or so in the not-too-distant future. We could see more SuperHeavy+Starship flights in 2026 alone than all the Gemini and Apollo launches, combined. With SuperHeavy catches underway (an already thrice-proven thing) SpaceX will likely have so many boosters kicking around that they'll run out of places to park them. The rate of developmental progress we're all likely to see in the next 24 months will be something the world has never seen before. I'm not going to be the least bit surprised if they fulfill their contracts and land humans on the new schedule, start deploying the newer full-function big starlinks by the Starship load, and but a batch of Tesla robots onto Mars in the next window. As they solve each problem, the subsequent launches will tackle more new problems, with each success checkbox enabling multiple new developments. The rate of progress will leap after the first fully orbital Starship flight, and the new facilities will amplify the development pace. We're all going to have to learn to think entirely differently about what rocket development looks like. This will be more like hamburger production at some point. The limiting factor on how frequently SpaceX can fly is likely to be [a] FAA limits, [b] how fast he can get cryogenic fluids delivered to his launch complexes, and/or [c] burn-out of his workers. That's NOT the normal thing in spaceflight. Normally the limit is launch vehicle and spacecraft production rates.

        I'm a natural pessimist, and rather than being a Musk fanboy, I was rather skeptical about the guy long ago, and never expected him to be able to clear all the government red tape and succeed, but I've done my time in the aerospace industry and this guy and his SpaceX people are doing great work and breaking all the development models. I wish the FAA guys would have gotten out of his way long ago - they know far less about rockets and spaceflight than his people do and they cannot keep up with that unprecedented development pace. As an agency, they're also severely risk averse and do not want to have to explain to congress why they approved something that went badly, so for them the easy and safe path is to not approve things or approve them very slowly and with heavy regulations. They'd have NEVER allowed the Wright Brothers to fly, or Wiley Post, or Charles Lindbergh, etc. Had the FAA managed to adapt to a faster pace with a different dev model, or had they gotten out of the way, I suspect we'd have seen an

      It's called "fail fast engineering." Instead of navel-gazing about what could go wrong, you slap the thing together and test it. In the tests, things likely to go wrong in fact go wrong. So you fix them and test again. Repeat until things start going right. Turns out that repeatedly losing test vehicles is actually cheaper than the long, detailed engineering necessary to find the problems without losing as many test vehicles.

      Great plan, right? Just one problem. There are high-probability failures and low-probability failures. The long, detailed engineering identifies both. Fail-fast only finds the failure modes which actually happen -- namely the high probability ones. And that's a big problem.

      You see, there are a whole lot of unlikely failure modes. Vastly more than the number of high probability failure modes. So while there's only a small chance of encountering any particular low-probability failure mode, there's a strong chance of encountering -some- low-probability failure mode.

      SpaceX has no idea what those low-probability failure modes are. They didn't do the long, detailed engineering that could identify them. They'll encounter the low-probability failure modes for the first time later on... when people are aboard.

        unfortunately - i think you're correct. I'll add to that that they have had repeat issues on things that they have had tons of experience with in previous iterations - leaks, engines not igniting/shutting down mid flight, heat shield panels detaching/failing, and the common: payload mechanism failed, and payload couldn't deploy. They have had these issues before, and keep having these issues. So not only are they failing fast, they're not really learning fast.

        The sheer number of engines that have failures mid mission is worrying, and they haven't improved much. This may have been the most successful. I'm glad that they have so many extra to account for some failures... but you don't do space missions, especially manned ones with "hope" that enough of them actually work. This launch, they had a successful 33/33 work on the ascent, but only 12/13 worked on the descent causing a loss of the stage. Still had a fuel leak that caused the loss of the upper stage.

        They're doing good work, and I'm glad.. but still, concerning... just glad that there hasn't been a catastrophic failure in orbit that would litter LEO with debris. (Yet)

The painstaking detail for SS/SH will have to come, but can and should be deferred until they have platform that has been proven basically reliable.

Maybe time to do some targeted ground testing of Starship or even fly it solo a few times.

  • Most other rockets of that size succeed with minor issues in first launh. Launching the rocket shouldn't be that much different from other rockets. Re-using it is a totally other ball-game, but why not do it, how they did successfully with Falcon 9: Get it usable and then figure out re-usable. I.e. get Starship to orbit without reuse (but reuse ready), launch Starlink satellites, then reuse boosters, then start to recover and reuse the ship.

        Real engineers prefer non-destructive testing.
