You know what was huge? James Webb telescope.

Look its cool to see a catch like this, it doesn't necessarly feels that difficult tbh?

And I just don't get it? Is it cool to watch? yes, but whats the endgoal besides reducing costs for starlink and military stuff?

Do you want more cool stuff like James Webb in orbit? Fully reusable huge rockets like Starship is how you get them there.

Also, remember how JWST had to do that incredibly complex and fiddly in-orbit expansion and alignment to fit together the mirror after launch? If Starship had been available at the time, this would have been far easier, since Starship has twice the diameter (four times the area) of the Ariane rocket they used to launch it.

Can Starship get to L2?

		Yes without a shadow of doubt it could deploy two JWST on a single launch. Add in the refuling they successfully demonstrated and the sky is no longer the limit.

Besides that I really really wished it wouldn't be Elon Musk, i'm looking forward to cheaper stuff so its easier to send science stuff up. Don't get me wrong at all.

But it feels like hyperbole.

Pure technically speaking, if you can fly a rocket up and control it properly, whats the crazy thing flying a rocket back down and controlling it?

Or do you see it more like a milestone seeing?

And for me, it still feels like if Elon Musk tries his Dataenter 'idea' and really sneds up everyday a Starship, we will lose a lot of control as normal humans whats going on in space and what will happen to our atmosphere.

I think the main challenge is really the heat shielding. That is the part that is so different from the takeoff. And it actually remains to be seen if that is good enough for repeated rapid reuse.

It only took the entire existence of humanity to reach this point.

I'm not willing to hand-wave that away as some kind of technologically-obvious conclusion.

"It only took the entire existence of humanity to reach this point." as everything else.

EUV required genuine new engineering for an example.

To pick just one achievement among many, the Raptor engines on the Starship are literally revolutionary. First ever full-flow staged combustion engine, designed for both extreme reliability and cheap mass production, even the fuel they use (methalox) had never been tried at this scale.

		I agree with the engineering of Raptor engines, fair and square but does that have anything to do with catching ar ocket?

You are absolutely right. Same thing about just putting a battery and some motors to make a car like RC car! Same about 48v/replacing canbus. Same thing about putting some satellites on orbit for internet! Same for mobile service! Same about if humans can use eyes to drive, computers should be able to using cameras! All _simple_ things, obvious in retrospect.

Yet one man is marching forward, poking his nose in industries he does not belong, and still almost always coming on top.

Makes you wonder why existing incumbents can't do these "simple" things.

One man who got money, has money and a cult following.

Of course he is flexible enough mentally and ignorant enough to disrupt markets, sure and for this he got rich.

But why does every Musk follower ignore all the bad things he leaves in his march forward?

All the humans around the Space-X 'city'?

Kids and Humans affected by USAID and DOGE?

His lying around everything he promised to people?

This thread is about an achievement made by the thousands of people working at one of his companies. Elon is only a small part of the equation.

Also, I don't understand what you're even trying to say by "ignorant enough to disrupt markets". There are plenty of rich people flinging money around, few have achieved anything near what Musk did. Look at Blue Origin, which is still playing catch-up despite SpaceX already proving everything and Bezos throwing basically infinite money at it.

		Its a comment and comments reflect discussions. Every success of his companies, give Elon Musk power and deminishes everyone who is or was affected negativly by Elon Musk. What would you expect if HN had an article about Fat Boy launched successfully on Japan? Pure positive comments?

?! We know how to send rockets up, we know how to send them back to earth. We know how to stabilize a rocket. I mean we fly them for ages?!

'that difficult'

Look at projects like James Webb telescope.

You don't understand the precision required to catch a 70m tall behemoth when you have Earths atmosphere. It's not even close to bringing a capsule to an approximate area, a small ship somewhere with almost no atmosphere, or even landing a rocket on a pad (which we've only had since Falcon 9)

But others are also working on it and showed they can do it too?

		Today was literally the first time humanity flew a rocket to orbit and landed it vertically.

“The James Webb telescope is just a three mirror korsch telescope in space. We’ve known how to build those since the 30s and we’ve been putting telescopes in space since the 60s. Doesn’t seem that impressive”

This is what you sound like to everyone else here

		And i can easily explain to you why this is not the case. They put the most advanced telescope at L2 which is the most remote location 1.5 million km away which can't be serviced and can't be rebuild easily. It has nanometer optical precision in space which needs to be cooled through multiply layers of high tec foil. Its mirrors are precicse to nm level. Took 25 years of planning and 5 years of building.
