    You’d think making a big clamp is easier than making a rocket…

      They’re rocket scientists, not clamp scientists.

        It’d be easier to train clamp scientists to static fire than to train rocket scientists to clamp.

            We can pretty much assume whatever needs clamping’s less than 28” thick.

    Wow, that’s wild!

    Space Pioneer issued its own statement later, stating there was a structural failure at the connection between the rocket body and the test bench.

    Sounds like the hold-down clamps failed. Have there been any previous cases in history where static fires unexpectedly turned into non-static fires?

        Few people know that one of those kids was now famous actor, Joaquin Phoenix. I watched that documentary many times and was shock to find out that people speak in a type of slow motion when in zero G.

          Technically speaking it was low-G. None of Joachim Phoenix’s movies are strictly “zero-G”

      In surprised a failure like that led to it being launched straight up like that.

        I was thinking the same thing. You can kind of figure out the distance from the time the rocket disappears behind the cloud/hill to the time you hear the explosion in the second video. The rocket disappears at 41 seconds and the explosion is heard at 49.5 seconds. Even if the rocket had hit the ground as soon as it disappeared from sight we’re talking 2-3 kilometers away.

          Even if the rocket had hit the ground as soon as it disappeared from sight we’re talking 2-3 kilometers away.

          That seems uncomfortably close, especially given this statement:

          The rocket’s onboard computer automatically shut down the engines and the rocket fell 1.5 kilometers southwest.

          I assume they mean 1.5 km from the test stand? If the rocket had flown a bit further, or in a different direction, it could have fallen in what looks to be a rather densely populated area.

                rocket fuel, which isn’t great for pretty much anything alive

                Depends on the rocket fuel.

                • Methalox: Harmless gases. Methane is a greenhouse gas, but it’s not toxic. Basically like a bunch of cows burping.
                • Kerolox: Kerosene is an oily liquid, so not great for the environment, but not highly toxic.
                • Hypergolics: Hydrazine derivatives and nitrogen tetroxide are both highly toxic.

                The Tianlong-3 in this article uses kerolox. The Long March 2C booster which fell near a village last week uses hypergols.

                  Yeah, primarily hypergolics are the fun ones. I didn’t hear about the booster that fell near a village recently, but there was one that I think had an emergency dump over some village or town a few years ago.

      CNSA would be “Temu NASA”.

      Space Pioneer is more like “Temu SpaceX”. Their aforementioned Tianlong-3 rocket is pretty much a Falcon 9 clone.
