  • That’s not exactly how it is right now, but it’s not far. Hell, the last time a F9 booster went splat, they grounded them for only a couple weeks before it was shown it wasn’t a safety-critical issue.

    It just stands out because there’s only two flying reusable boosters right now (and only one that can go to orbit). Meanwhile, grounding one model of aircraft doesn’t usually have that much of an impact because they are so many active. What’ll be really cool is when there are so many reusable boosters out there that one can be grounded and spaceflights will just continue on another.



  • I’m wondering if the remaining fuel in the lower segments of the ship gave those sections more momentum, causing the whole hull to pivot around those heavier sections (especially with the loss of thruster capability being discussed).

    With the Space Shuttle, this tendency was largely offset by the delta wings also causing greatly increased drag at the rear of the hull, but with fins folded the Starship doesn’t really have this. That plus the seeming loss of control due to thruster malfunction…







  • So by all means correct me if I’m wrong, but is this really that bad?

    Like, people always freak out about “turning one falling object into many” because they would still share the same collective kinetic energy, but smaller objects are far more likely to burn up high in the atmosphere rather than penetrate for a destructive impact.

    The article describes 37 boulders, each with a ~15kT kinetic energy. We have record of meteor events in this magnitude, and they aren’t terribly destructive. Nor is it more than a footnote in terms of Earth’s daily total energy budget; the Earth isn’t going to be cooked by a meteor-swarm of this scale.

    It’d seem to me that the biggest risk would actually be peppering Earth’s orbital region with far smaller objects that could still damage satellites, no?
