Starship is, essentially, Space Shuttle done right: fully reusable booster without solid boosters (avoids Challenger disaster) and orbiter stacked on top instead of on the side (avoid Columbia disaster).

The original designs for the Space Shuttle had the booster (with wings!) return to the launch site, but the cost for two new crewed vehicles was too large, so they scaled it back to the compromised version.

Even more revolutionary, compared to Shuttle, Starship is built on an assembly line. They can build a booster ever 4 weeks and a ship every 2 weeks.

The future we were promised in the 1970s is about to become real.

If the heat shield holds up then this changes everything. Next step is double catch and re-flying the same ships and catching again, then payloads to orbit become significantly cheaper opening a new era in space flight.

Huge congratulations to the engineering team on this one! It's been quite interesting to watch the evolution of Starship. Had they put another couple of tonnes of propellant and oxidizer on the Booster they might have caught both of them. It is still unclear to me what the final mass fraction to orbit will work out to be, but something that is 100% re-usable is better than something 60% reusable[1].

[1] Estimate of Falcon 9's booster + fairings being 60% (by cost, not by mass) of the launch package.

Insane achievement! It is the dawn of a new era! One that has been 10+ years in the making.

To everyone who works at SpaceX and read this. You are all amazing.

I hope other great minds at SpaceX are well remembered into the far future.

If this makes even me want to go study engineering I know it will inspire millions of youngsters into making the future we all want. Bravo!

The engineering of this is just mind boggling awesome. The culmination of so many fields, so many factors, to this. Congrats!!!

Watched it with my 5 year old daughter (3 year old son was sadly uninterested), and we were both cheering and high fiving. Very exciting.

So precise it was almost boring - incredible work. Kudos.

I know engineering is about expediency, and price, but I’m still bummed that we aren’t getting ships with landing gear in this or likely the next generation of rockets either.

Seems that the heavier the rocket the more ground clearance to need to self-land, and so you can’t scale up the dragon’s landing system. I don’t think there’s anywhere near enough weight to shave off of the next rocket or enough specific impulse to add to bring the size back down.

The "Baby Come Back" soundtrack really brought this home for me. What an incredible achievement. Very moving.

Honestly if this thread had the actual number of points it deserved based on the kind of milestone this represents for humanity's future and access to space, it would be in the millions.

If you don't follow rocketry you can't possibly understand what this means.

This was the Trinity test.

And even if you hate Elon and all his businesses, this knowledge will proliferate. Either by talent movement / osmosis, by espionage or just being inspired ("if they can do it, maybe we have a chance as well").

Within a decade the average cost to LEO will drop 20x-50x and if you're not recovering both of your stages, you don't exist.

will scaling the size of the rocket continue to be the way to go? will doing a three stage setup make sense?

Holy ship, it was picture perfect capture!

This is absolutely incredible!! I can’t wrap my head around this.

clivedup • today at 12:05 AM

Can anyone explain this to an idiot like to me? I follow information tech, but am pretty ignorant on engineering/space.

I recall the SpaceX chopsticks catch from about a year ago, which looked great.

This looks similar (heavy thing lands smoothly on a platform) but I gather it's very different from the comments?

That was incredible to watch!

If you ignore the scale it doesn’t seem all the impressive. But the scale is bonkers.

Ah man I just missed it. The live feed is just stock footage. Any links to the catch?

The heat shield looks very good. Excited to see how much work it will take to fly this again. I'm in awe. I like the future sometimes.

Best thing ever built and it works!!!

How many years until the next milestones?

- in orbit refueling

- moon landing

- Mars rendez-vous

- Mars landing

- humans on Mars

Nah, the game is to put data centers in space. Plus the Space Force dreams.

This is incredible. Huge respect for the engineering team. What a time to be alive.

As an aside, it’s been fun watching the number of UFO posts on Reddit while Starship orbited Earth. They all refused to believe it was SpaceX.

It's difficult to underline how huge this is. This marks the first time in the history of rocketry that the upper stage of a rocket has returned home from orbit to a safe, upright landing.

(And to preempt the obvious objection: yes, maybe you can call the Space Shuttle an "upper stage of a rocket" if you squint hard enough, but it didn't do upright landings, its external tank was not reusable and even the Shuttle itself was effectively rebuilt from scratch at exorbitant cost each time.)

It's sad to see a lot of media missing the point, eg as I type this BBC is reporting this as "SpaceX successfully catches part of Starship rocket on its return to Earth".

Edit: corrected to note that the SRBs were reusable, but the ET was not.

panick21_ • yesterday at 9:29 PM

Kind of crazy to reduce the hardware on ship so much and move so much complexity to the ground. This can really only happen in a situation where anybody can throw out any dumb idea, because if you suggested this 20 years ago people would think you are an idiot.

perfect. hyperbole failure moment

rvz • yesterday at 9:29 PM

This is exactly the most impressive feat of engineering I have ever seen.

Only catching both the booster and the rocket would top this one. But the rocket only being caught is still impressive regardless.

SpaceX below $1T is criminally undervalued.
