So I’ve heard and seen the newest launch, and I thought for a private firm it seemed cool they were able to do it on their own, but I’m scratching my head that people are gushing about this as some hail mary.

I get the engineering required is staggering when it comes to these rocket tests, but NASA and other big space agencies have already done rocket tests and exploring bits of the moon which still astounds me to this day.

Is it because it’s not a multi billion government institution? When I tell colleagues about NASA doing stuff like this yeaaaars ago they’re like “Yea yea but this is different it’s crazy bro”

Can anyone help me understand? Any SpaceX or Tesla fans here?

Disclaimer: Fuck Elon Musk and all the shady shit he’s been pulling off.

That said, this is one of the most impressive things I’ve ever seen in terms of the potential it holds to shape the future.

Up until 5 short years ago we had:

  • No main booster recovery
  • No rocket nearly as powerful as this one
  • No successful flight of a full-flow stage engine
  • Nobody even considering the catch with chopsticks thing
  • No private company testing super heavy lift vehicles (BO is about to enter the chat as well)
  • No push for reusability at all

This was all built on top of the incredible engineering of NASA, but this one launch today has all of the above ticked.

This is like making the first aeroplane that’s able to land and be flown again. SpaceX uses this example as well, like, imagine how expensive any plane ticket would have to be if you had to build a brand new A380 every single time people wanted to fly and then crashing it into the sea.

Going to space is EXPENSIVE. If this program succeeds it will both massively reduce the cost to space and spin off hundreds of companies looking to do the same in various ways.

Look at any new rocket currently in development, they all include some level of reusability in the design and that’s all thanks to the incredible engineers of SpaceX paving the way, first with Falcon 9 and now with Starship.

We’re talking industrial revolution levels of progress and new frontiers in our lifetimes, which is very, very exciting.

I hate Musk and his personal everything, but Like SpaceX. However, when people gush about reusability, they seem to forget the 135 Space Shuttle missions (2 fatal failures , yes.). All done with 5 vehicles. Yes expensive etc, but truly amazing.

Also, I really don’t find anything SpaceX is doing revolutionary. Impressive? Yes, but it’s essentially incremental engineering, made possible by ginormous funding, including NASA money, and a private company doing things that NASA can-t politically afford.

Imagine NASA crashing 4 Shuttles before getting landing right. There’d be no NASA by now.

NASA spent about 50 Billion today-dollars developing (not launching) the shuttle program and that went to private contractors (Boeing, Lockheed, United Space, etc.) Starship has a long way to go to hit those numbers.

I really don’t find anything SpaceX is doing revolutionary

Really? Nothing? Many people said what Falcon 9 now does on a regular basis could not be done. No one was even trying. The closest plans were still going to land horizontally and went nowhere. Now, you have to explain why you’re not landing your booster, and what your plans are to fix that going forward: https://www.bnnbloomberg.ca/business/international/2024/09/11/china-wants-to-replace-jeff-bezos-as-musks-greatest-space-threat/

They quite literally revolutionized the space industry in terms of the cost to launch to orbit.

Imagine NASA crashing 4 Shuttles before getting landing right. There’d be no NASA by now.

Yet another way they’ve revolutionized the industry. Almost everyone is doing expendable tests now so that they can move forward quickly. Columbia started construction in 1975, launched for the first time in 1981. When they launched it, it was a fully decked out space shuttle and they put the whole thing on the line - including two astronauts. Imagine NASA trying to do that now. They’d be grounded so hard they’d be jealous of Mankind having a table to land on.

I tried to explain to someone months ago that SpaceX testing things to failure was part of their success, and gave an example like purposely leaving heat shield tiles off starship to see what happened, or launching a version of starship that didn’t have all the improvements that the next starship had, and they then came back saying that is exactly why they (and other people) hate SpaceX. They don’t know everything up front and they should!

The Space Shuttle missions did not recycle the rockets, not to mention that the SpaceX missions were rated super-heavy: Only Apollo has done this before in America.

The Solid Rocket Boosters (SRBs) from shuttle launched were recycled. They parachuted into the ocean after being jettisoned and were recovered and refused. They just didn’t land themselves. The external fuel tank was not reused.

No, they didn’t. Enterprise conducted 5 approach and landing tests where she was carried aloft by a 747 and then detached to glide to a landing, three with that aerodynamic tailcone thing, two with mockup main engines to simulate a return from space. Though there were issues with PIO revealed during the last flight, all five of Enterprise’s approach and landing test flights resulted in successful landings.

I would not describe any space shuttle as “crashed.” Challenger exploded during launch and Colombia broke up during re-entry; destroyed in service yes, crashed no. Enterprise, Atlantis, Discovery and Endeavour all survived service and are on display at museums. No other airworthy space shuttles were built. Explorer/Independence and Inspiration are 1:1 scale models, and Pathfinder was basically a boilerplate meant for testing and incapable of flight.

The Space Shuttle was a marvel of engineering. But while it was reusable, it wasn’t actually good at it. Reusability was supposed to bring down cost and turnaround time and it did neither. And not just that, it was actually much more expensive than competing expendable rockets. Plus, it had lots of other issues like being dangerous as fuck. You couldn’t abort at all for major parts of the ascent and there was the whole issue with the fragile heat protection tiles, both of which caused fatalities.

I think part of the reason why people aren’t impressed by the Shuttle anymore is because it flew 135 missions. It’s 40 year old technology. And it’s not like SpaceX are just doing the same thing again 40 years later, they’re reusing their rockets in a completely different way, which no one else had done before. And in doing so they seem to be avoiding most of the disadvantages that came with the Shuttle’s design.

Also, I really don’t find anything SpaceX is doing revolutionary. Impressive? Yes, but it’s essentially incremental engineering, made possible by ginormous funding, including NASA money, and a private company doing things that NASA can-t politically afford.

Sure, I wouldn’t say that no one else could do this with a similar amount of money (and the will to actually do it). Whether you want to call it revolutionary or not is subjective, but they’re definitely innovating a lot more than any other large player in spaceflight. The Falcon 9 is a huge step forward for rocket reusability and SpaceX have also been the first to fly a full-flow staged combustion engine as well as the most powerful rocket ever. They’re making spaceflight exciting again after like 40 years of stagnation and I think that’s what resonates with people.

The space shuttle wasn’t as reusable as it was claimed to be.

Each airframe required massive refurbishment after every flight.

And the “crashes” you’re talking about were part of the project process, articles that were never going to be any more than test objects to begin with.

NASA crashed a lot of stuff, unintentionally. Three off of the top of my head, killed 15 astronauts, all which were preventable (not to mention the launch pad failures getting to Apollo).

NASA/NACA/Air Force crashed a lot of stuff along the way.

Ffs they knew Columbia had a tile problem, and said “it’ll be OK”. They knew it had been too cold for the booster seals on Discovery, and launched anyway.

The space shuttle was technically reusable, but not in a way that was beneficial to anyone. The time and cost of refurbishing the shuttle after every launch was so much they may as well have built a brand new disposable rocket for each mission.

SpaceX may have built the first reusable rocket that actually saves money

I thought it was the boosters that were in retrospect pointlessly refurbished and would have been cheaper to make new.

Are you sure it was also the shuttle itself being cheaper to make new? The shuttle also took something like 6 months to refurb. Reusable, but not rapid.

no rocket as powerful as this one.

So I’m confused on this because people still seem to be using Starships’s old estimates of 100 tons to LEO orbit, which the SLS can put 145 tons to LEO.

Then 6 months ago Musk got on stage and updated the specs to Say that Starships’s current design can only do 40-50 tons.

This feels awfully familiar for anyone that’s seen early Tesla specs/presentations/promises and I can’t help but wonder as to the validity of everyone saying SpaceX is mostly insulated from Musk’s “influence.”

To be very honest even if Starship is able to only lift 50 tons, which I’m sure they’ll be able to hit 100/150 tons eventually. The huge difference in cost would easily cover the extra times Starship would have to fly, compared to SLS. Considering each flight of a SLS will be around 4 billion dollars.

I think they mean the “superheavy” (somehow a more stupid name than starship) booster rocket is the most powerful. I’m pretty sure by thrust metrics it is. It’s just that the superheavy-starship system can’t put much up in LEO because the starship is huge and heavy on its own.

If you put an expendable second stage on top of the superheavy booster instead of a starship it could put a lot more up to LEO.

The Saturn V could lift 141t to LEO…once. Also it’ll be at least another 5 years before we reach a stable max power version of Starship.

For example the Falcon 9 v1.0 first flew in 2010 and the current Block 5 version first flew in 2018 with more than double the LEO capacity when fully expendable.

If they configure Starship as fully expendable it can lift 250t to LEO (per SpaceX, so grain of salt there to be fair).

As for the shuttle, I love it to bits and I’m sad it had to be grounded. It was refurbishable but not really reusable and the massive liquid fuel tank was discarded in each flight.

Yes. It’s down right scary to think about what the consequences of private ownership will mean.

In best case it will turn into a profitable business which means burning a shit ton of fuel in the atmosphere and leaving tons of garbage in orbit.

Yes it’s impressive that it’s possible, but is it less impressive if it means screwing up the option for others to launch anything in 50 years just because the richest man on earth right now wanted to earn more money.

It’s a small step for a large corporation, but it’s a large step backwards for humanity.

I’d rather see new technologies like the slingshot launches becoming successful than seeing SpaceX launching the same old dirty rockets over and over for profit.

So I was teaching some kids snowboarding, one kid started talking to me about musk on the chairlift. He tells me that musk is the greatest engineer to ever live. I say that he’s really more of a business man buying up companies. Kid is not convinced. I tell him that the only engineering that musk may have done was software engineering on PayPal. Kid thinks that’s great support of his claim.

Adults and 11 year olds are pretty much the same, so I would say there’s lots of people that think musk is a super genius. Probably a dwindling amount, but there’s a lot of people on earth.

Unfortunately, a lot of smart people are under his spell too. I had to listen to the CEO of a medium sized company wax poetic about how he’s a super genius and the greatest boon to human ingenuity in a century, desperately trying to hold my tongue as I rolled my eyes into the back of my skull.

I think he’s an okay businessman. That’s about as much praise as I’m willing to afford him. He’s definitely charismatic enough to convince a room full of investors that the ideas he’s pitching are worthwhile. Part of that is that his passion for these projects are genuine, and when you put somebody in a room with a passionate guy, the enthusiasm tends to rub off on them just a little.

Most of his investments that garnered him his wealth are just him being at the right place at the right time. Getting in on PayPal when Ecommerce was in it’s infancy and partnering with Ebay to take advantage of shopaholics who just couldn’t help themselves. Buying his way into Tesla right when EVs were primed to take off and pushing hard for an economy class variant that could be mass produced rapidly (in an already-made factory that Toyota closed down, no less!). Founding SpaceX and pouring a shit ton of his own money into rocket and aeronautics R&D right around the time the U.S. Government was looking for cheap contractors to take over the space program. I think the only project he miscalculated on was buying Twitter for way too much money when social media was really starting to stagnate.

His politics are fucking weird, though. Him being a Trump nutter is really not helping his “I’m a genius” image. I find his personality to be pretty repugnant. I already didn’t like him because back in the early days of Tesla he pushed all the management to essentially become slavedrivers for the line workers. I live in California near the plant and I had friends who worked there in production that got nearly worked to death, extreme overtime and weekend shifts, few breaks, the only saving grace was the above average pay that kind of kept them trapped in that hell of a job for way too long. Then the whole Thai soccer team incident happened and I was so over him. Haven’t heard anything about him since that has made me feel like he deserves to be the richest cunt in the fucking universe.
