Again, the only possible player that could do that any time soon is blue origin/Amazon.
Stoke Space is working on a fully reusable rocket though, I'm really impressed with their rocket concept, some very smart design choices were made. They do have working hardware and have demonstrated their core engine. But I have no idea how close they are to first launch tests, I expect it will be a while
Your original comment said 2050, which is a long way off. SpaceX's first launch attempt was in 2006, their first successful launch was in 2008, their first successful recovery of a rocket in reusable condition was in 2015, and first reused a rocket in 2017. If they can make progress on that kind of timeline, why wouldn't someone else be able to?

You mean like Starship?
I plead the 5th....

That's a fair point. The alternative is taking things up to a "graveyard orbit" somewhere between LEO and GSO, to a particularly unpopular altitude, where nobody's fighting for real estate. Satellites can sit there indefinitely, you could even clump them up in a big ball, the tiny pull of gravity they have is actually enough to keep them bunched together.
The only problem with that plan is that it takes a lot of energy to raise an orbit that much, I'm not sure how to make that feasible.

Lowering the orbit takes energy, too, unless you're relying solely on atmospheric drag.

Arianespace has fallen behind, but they're not out of the picture. They're still by far the largest competitor to SpaceX, and they're aiming for their 7th generation Ariane to be a reusable design.
Arianespace is an Airbus and Safran subsidiary, so it's not like they don't have the engineering oomph behind them.

That's a fair point. Keep in mind though, it takes a while to get a whole constellation up in orbit and get all the kinks worked out, Starlink was first usable in 2020. So in total it took them in the area of 14 years from start to finish. It's also worth noting, that nobody in the space industry has really ever been able to move as fast as spaceX, they're something of an anomaly, not the norm.
So could a new company do it in 14 years? Yeah, that's definitely possible. It could happen by 2039, but I wouldn't put money on it. 25 years seems more likely.

And Hyundai is making hydrogen powered tanks, what a world. I wonder if hydrogen fuels poses any unique risks as compared to petrol.
Well, they're DEVELOPING them. They're not MAKING them yet.

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.

Sure, but you can safely deorbit something from Leo with like 100 m/s of Delta v, you just need to dip into the atmosphere and then drag does the rest. Getting something to a sufficiently high graveyard orbit is more like 2000 Dv split between two burns. You'd need to stay with the trash for half an orbit and then do the second half of your burn, and then presumably you'd need to travel back to your original point, costing another 2000 Dv.
All together, going up could take 40x more propellant than going down.

We won't live that long.

Not with that attitude!

I am ABSOLUTELY not praising SpaceX, I'm just using them as an example of how scale makes all the difference at least for some of the components. And being able to launch a small rocket is evidence they can launch a big one too.

N420HA. Not sure if that's the model or the plane's license plate but either way hell yeah
N420HA = and 420 hah
I bet it's high af rn

Imo it's a good thing tho. Spreading our civilization across multiple planets is the only way to guarantee long long term success. Obviously we should also fix the climate change issue (and many others). But still, being spread across the solar system would give our species redundancy. An extinction event on earth like a large meteor strike would no longer be the end.
Well good thing it will never happen.
️Imagine trying to undo thousands and thousands of years of evolution surrounding…. Earth’s gravity.
But you go ahead and fantasize about us destroying all the planets in the universe. After all; we’re the only thing destroying ours.

Not saying they don’t. Just saying the “ungodly hours” statement may not apply
Probably still a less insane megalomaniac for a boss at least though.

Call me an optimist, but I still hold the hope that we can one day do better as humanity than we do now. Humanity has become a "better" species throughout its existence overall. Even a hundred years ago we were much more horrible and brutal than we are now. The current trend is not great, with climate change and far-right grifters taking control. But I hold hope that in the end this is but a blip on the radar. Horrible for us now, but in the grand scheme of things not something that will end humanity. It might in the worst case set us back a few hundred years.
