Comment on Honda successfully launched and landed its own reusable rocket

• moseschrute@lemmy.world ⁨1⁩ ⁨day⁩ ago

  There’s a YouTube channel called BPS Space where this guy spent 7 years learning how to land a model rocket space x style. He talked about how much you can learn about real rocket science even from a small model.

    This is the same guy.

  You mean like Starship?

  Whatever they tested it’s probably proof of that, but such a small rocket and only 300 meters means that a lot of things were not really proven, because scale is a HUGE issue.
  Just ask Elon Musk / SpaceX, the Falcon rocket is fine, but Starship is horrible. And the difference is scale.

    That is not why starship fails. Starship fails because like everything that Elon does lately it emphasizes style over practicality. Starship is a very badly designed rocket that looks cool to Elon. Not unlike the Cyber truck which has been an abject failure in every way possible.

      My personal opinion is that it fails because SpaceX, like a lot of space startups, embrace a silicon valley coding mindset of ‘move fast and break things’, which results on them spending much more of their time and effort on testing than on design. Make a change, test, make a subsequent change, test. There’s no emphasis on modeling or design, which is problematic for for complex problems that haven’t been solved for 50 years.

      You are missing the point that size makes a difference. Obviously SpaceX has the technology to do what Honda did, but SpaceX can do ti with a real rocket.
      But they can’t do it with the bigger Starship rocket. Scale matters.

        And when SpaceX does it with real full size rockets and they explode scattering debris and chemicals everywhere, the nearby towns pay the price.

        I don’t see any towns being decimated by Honda’s approach.

        Size is only a proof of logistics. Not tech. Physics don’t change fundamentally between 6 meters and 120 meters. You learn a lot from scale modeling without the added costs. Starship’s real challenge is actually the logistics necessary to fulfill the desired specifications and experimenting with engineering to reach the scale. The most innovative aspect of Starship would be orbital refueling, and they aren’t there since the thing hasn’t reached orbit yet. SpaceX problem right now is insisting on high turnover engineering, which doesn’t work at scale without heavy costs, because it is a logistic problem, not a engineering problem.
