Comment on Honda successfully launched and landed its own reusable rocket
Buffalox@lemmy.world 1 day ago
This wasn’t much more than a toy rocket:
6.3 m in length, 85 cm in diameter,
The test was completed successfully, the first time Honda landed a rocket after reaching an altitude of nearly 300 meters.
But still they were successful on their first try, so we will have to see where they take it from here. 🚀

It’s proof of tech. It’d be stupid and wasteful to do all the tests on a full size rocket.

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.

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.
