SpaceX's Starship Reaches Outer Space Before Intentional Detonation (cnn.com) 125

CNN reports SpaceX made a second attempt to successfully launch Starship, the most powerful rocket ever constructed. The uncrewed rocket took off just after 7 a.m. CT (8 a.m. ET). The rocket took off as intended, making it roughly 8 minutes into flight before SpaceX confirmed it had to intentionally explode the Starship spacecraft as it flew over the ocean...

This mission comes after months of back-and-forth with federal regulators as SpaceX has awaited a launch license. The company is also grappling with pushback from environmentalists...

After separating from the Super Heavy rocket booster, the Starship spacecraft soared to an altitude of approximately 93 miles (150 kilometers) before SpaceX lost contact, according to a statement issued by the company. For context, the U.S. government considers 50 miles (80 kilometers) above Earth's surface the edge of outer space...

SpaceX is OK with rockets exploding in the early stages of development. That's because the company uses a completely different approach to rocket design than, say, NASA. The space agency focuses on building one rocket and strenuously designing and testing it on the ground before its first flight — taking years but all but guaranteeing success on the first launch. SpaceX, however, rapidly builds new prototypes and is willing to test them to their breaking point because there's usually a spare nearby. During a drive by the company's facilities on Friday — four Starship spacecraft and at least two Super Heavy boosters could be seen from public roadways.

CNN reminds readers that "so far in 2023 alone, the Falcon 9 has launched more than 70 spaceflights...

"Elon Musk described Starship as the vehicle that underpins SpaceX's founding purpose: sending humans to Mars for the first time. NASA has its own plans for the rocket."

    All the engines fired.
    Booster separation successful.
    It made it to space.
    Self destruction detonation successful.
    The launch pad is still in one piece.

    So they fixed all the bugs from the previous test, and achieved some new milestones as well. Also they presumably collected a wealth of new data.

    I call that a win!

        And that's why SpaceX has progressed so rapidly. If a NASA development project explodes, someone who mostly have undergrad degrees and are responsible to a bunch of people, more than 10% of whom don't have a high school diploma, read the headlines and decide whether the project should continue. If a SpaceX rocket explodes, a small and selected group of space nerds say "great, we got valuable data, how soon can we do this again?"

        Besides, I think Musk likes it when people say mean things about him. I bet he was one of the original Slashdot trolls.

        • The bigger problem for NASA is that congress (who hold the money) today won't put up with a test to failure type of mentality, especially when it's using some hardware that was engineered by legislation basically (aka, force to use shuttle hardware/vendors).

      • Musk is using the "fail fast" approach: Instead of spending inordinate amounts of engineering figuring out what might go wrong and preventing it, just try it and see what actually breaks. Then you know what to fix.

        Fail fast works after a fashion. You quickly zero in on the probable failure modes and solve them.

        The problem is, there's not a lot of depth to the engineering. You find few of the unlikely failure modes this way. And you build no foundation for understanding what failure modes lie on the other si

        And there's no reason not to. Musk didn't design this rocket, he was too busy destroying Twitter. SpaceX is amazing. Musk has shown to be quite a piece of shit the past few years. Both are independent things in this world.

      Well, it's a step forward, and if you keep making progress you will eventually get somewhere.

      All the engines did fire, but it appears that engine failures on both the booster and the starship caused the loss of both. I think it's acceptable at this point because this is a completely new engine. But it's hard to judge exactly how much progress we've made to making this thing man-rateable.

      • I think part of the issue is Musk's timeline pronouncements consistently turn out to be wildly wrong, yet his acolytes still keep believing and parroting any new claims he makes as if they were gospel. If he just kept his mouth shut, there wouldn't be nearly as much drama around any of his companies.

        I mean, look at Starship. It's making steady progress, and it's likely to be a success... but it's certainly behind schedule. It certainly seems unlikely it'll reach the moon next year [space.com] (and obviously Musk's clai

          Oh please, look at SLS, that one should have been flying many years ago according to NASA, but didn't until a year ago, and that setback wasn't even caused by things like the FAA. In spaceflight development it's hard to get a good timeline, but you do have to try and set goals for a set timeframe. At least with SpaceX any slowdown is coming out of Elon Musk his own pocket, with NASA it comes out of the civilians pocket, which is why a lot of projects tend to go over budget/time, as it's the taxpayer who is paying for it. If it weren't the taxpayers who paid for SLS, it would have been scrapped years ago.
        • by hey! ( 33014 )

          Well... that's the whole *point* of Elon Musk. If he has any value at all to society, it's to get investors to risk their money on game changing technology and then stick with it through the inevitable setbacks. He's not Tony Stark; he's not an engineer, he's someone for people who wouldn't respect actual engineers to believe in.

    • Because musk consisted on cost cutting measures around the launch pad resulting in some debris breaking loose and striking the rocket? Not a huge space nerd but a buddy of mine is and that's what I heard from him. If they didn't cut those corners the second launch it would make sense it was successful.

      SpaceX says they lost data from second stage. So there are no lessons learned from that part. Second stage is not cheap to build, they should have better data reception coverage on its fly path. They could be more proactive so I cannot call it so clear win.

        Naive question, but... is there any kind of "black box" that they might be able to recover from the wreckage, in order to get some data?

          Unlikely that would survive re-entry, and if it did it would sink to the bottom of the ocean

      • by catprog ( 849688 )

        They probably still have data up to that point.

    • I think the key question is where they are relative to the schedule required not to delay Artemis - the first major application of this booster. That will be SpaceX internal info - how many and what types of failures they planned for.

      A lot of things did work, and there is a good chance the failures can be corrected. IMHO the biggest untested parts are the performance of the 2nd stage reentry system, and the 1st stage flyback landing - both of which are required for this to be economically viable. Lik

    Cannot understate how big a achievement this is. Congrats to all the teams at SpaceX (regardless of how you think about a certain Elon Musk).

    This is the largest rocker after Saturn V. Correction, this is the largest rocket ever, even bigger than Saturn V. It not only is taller (394 vs 363ft), it also has more cargo capacity (in final form). (Here is a more detailed comparison: https://www.bbc.com/news/scien... [bbc.com]).

    And... almost all test parameters hit correctly. The thing was able to keep all engines running, skimmed the edge of the space (on purpose), stayed stable and in control for about 8 minutes. The future is only brighter from here.

    It is good to see American engineers finally taking this seriously after a half a century of hiatus. Nicely done!

    • by AmiMoJo ( 196126 )

      It brings home how badly things went wrong after Apollo was cancelled. We regressed and took over 50 years to build something bigger.

      It will be interesting to see if they can get it ready for Artemis in 2025/26. Needs to be man rated for landing on and taking off from the Moon by then.

    Different news vendors are saying different things. The version I read stated that SpaceX lost contact with the rocket and it was assumed to have self-destructed.

    You'd think that there'd be a single narrative by SpaceX, but what we're left with is multiple accounts and a question of whether the destruction was indeed deliberate or whether that's a post-hoc cover story to avoid any repercussions.

    Honestly, until I hear a clear explanation for the multiple versions, I'm not going to accept any of them as necessarily true. The rocket was lost after it reached space, but that's the only fact that seems to be indisputable.

    • by kmoser ( 1469707 )
      Yeah, if they lost contact, how did they intentionally detonate it? Did Marvin the Martian blast it?
      • by ceoyoyo ( 59147 )

        The flight termination system auto-detonates if pre-programmed conditions aren't met. It's pretty unlikely they lost contact with it since it was still in visual range. In a day or two Musk will tweet whatever it was that made the system unhappy.

      It's pretty clear that the rocket self-destructed based on internal guidance showing that it was departing the allowed flight trajectory. This is required so that it can't spread debris outside of a predefined corridor. What we don't know, at least publicly, is why that happened. It could have been as simple as a sensor error or programming mistake making the flight termination system think it was off-course. It could have been something wrong with the engines. It could have detected that the rocket was in the process of exploding due to some catastrophic failure.

      I expect SpaceX knows exactly what went wrong. Unfortunately for us, they're not in the habit of giving out lots of technical details on flight failures.

      The good news is that it appears that any debris is going into the ocean where the FAA was expecting it in the event of a failure and the area around Starbase is all in good shape, so the review before the next launch license should be much simpler.

      So the question we'll hopefully get answered in the next couple of weeks is when they think they'll be ready to try again, which means having adjusted the design based on all the data they've obtained. It seems that they need some work on the hot staging design to avoid destroying the booster, though it was impressive that it didn't blow up until after Starship was well clear of it. And they'll need to fix whatever they think failed in Starship.

    • It is those newsreporters that made up what happened. If you followed the official spacex broadcast it's clear it was the auto-destruction of starship itself that triggered, not a deliberate action by SpaceX.
  • Musk does a lot of great things, but he definitely has some stupid ideas.
    One is going to Mars before returning and setting bases on the moon.
    Another is trying to get to Mars with chemical propulsion and not nuclear.

    • Well, what are you doing to get us to mars or the moon? SpaceX is already developing other ways to power their ships to get to mars, but that takes time and Starship is the most feasible vehicle at this time, also taking costs in consideration.

        "SpaceX is already developing other ways to power their ships to get to mars"
        Are those other ways nuclear? I'd like to read about that then.

        Look, we use nuclear for our submarines, our aircraft carriers, even Icebreakers because we acknowledged the limits of chemical propulsion. Starship looks to be a great vehicle, just don't send it to Mars. Chemical propulsion takes too long to get there.

      • Getting to Mars is the easy part. Doing so without condemning the crew to a dozen possible deaths is that hard part. Starvation? Asphyxiation? Radiation? Boredom? I am not seeing a decent plan for how to keep a crew, let alone a colony, survive there, or to even have a point in being there. Part of what we stopped going to the moon is that after a few hundred pounds of moon rocks were collected (and once you beat the USSR there), it ceased to have significant real science value. The ISS has been pret

  • Not hard to find for the booster, but the Starship was close to its planned trajectory. Did the pieces land somewhere in the Pacific?

  • ... the range safety officer is developing some serious muscle memory for hitting that Big Red Button. I'm not sure I'd like to be on the first crewed flight.

    Now if Elon Musk could just manage himself a little better...

    Yes. The OceanGate approach. Very sexy, but ultimately not something I'd trust.

  • Musk used the Mars story from the start of all of this.
    Videos of dad, mom and the kids holding hands in Elon City.

    But it's not built to transport people. You can see that by the design of it.
    It's a purpose-built Pez dispenser for Starlink deployment, and that's it.
    That was always the intent, but "it's for my Starlink network" is a hard regulatory sell.

    A Mars mission, should it ever exist, would be an interplanetary scale money hole for SpaceX.
    Starlink is already making money today, plus other benefits.
