Different design paradigms. In 1969, they had one shot to get everything right, and prepared accordingly (not to mention, they had a massive budget since the space race was all part of the cold war).
SpaceX is taking a different approach, fail fast and cheap. They are taking an iterative approach that allows them to learn from previous failures, rather than anticipating what all those failures could be and then over engineering the rocket to prevent that.
They are different approaches, and each has their own pros and cons. ¯\(ツ)/¯
That's a great summary, I appreciate it. Do you think the new approach has been worth it so far? The Artemis 1 launch was successful first try.
The Artemis 1 launch was also staggeringly expensive, and yet to be repeated.
In the time it's taken to develop that rocket, SpaceX has gone from it's very first real flight (by which I mean actually achieving something, rather than a pure test flight) to launching far more every year than the entire rest of the world combined. Note that by that definition, Artemis hasn't had a single "real" flight yet.
SLS did a lap around the moon flawlessly and returned safely.
Starship, a scale model of the empty shell that HLS might one day sit in, when it is finally developed, can't even land without exploding.
According to a recent speech by musk, it wasn't even the real shell. IFT3 was a 40ton-to-LEO craft, where HLS will have to be around 100, which would take the as of yet unflown and (mostly?) unbuilt "Starship 2".
And where SLS will simply have to do a repeat of what it has already done for Artemis 2.
HLS will have first be actually built, get launched, get refueled by a tanker craft that also doesn't exist yet, an unknown number of times (probably 12), fly to the moon, land there, take off, come back, land on earth and then do ALL of that again in time for Artemis 3 where it will have people on board.
SLS is 1 for 1, and if Starship IFT4 does everything right tomorrow, HLS is still at 0. And if it does everything right, I will buy a hat and eat it.
SLS is also ridiculously expensive. They hope, with time, to bring the cost down to $1 billion per launch. And the first one took 6 years longer than expected. If we're going to get to the moon more than one more time before I die, this isn't the vehicle I'm going to pin my hopes on.
SLS is currently priced at 4b per launch, based on its one launch.
Starship-HLS has cost at least the 2.9b from the NASA contract, and doesnt exist yet.
To put it in context, Artemis did many fully destructive tests but typically on the ground. Artemis had and spent an overhaul budget that was likely close to a hundred times that of what SpaceX is spending in today's dollars.
And even better representation, all the fully destructive tests of SpaceX have carried out have costs less than a single successful shuttle launch. And it has a much larger payload.
Even with the destructive tests, of which are planned this way, not only is SpaceX is far cheaper than any past space program, they are advancing fairly rapid.
They have completely different goals. If SpaceX wanted to throw out the Starship and Booster sections every time, they're already as capable as the Artemis launcher. But they are looking longer term, and want to also be 1000x cheaper.
It took them dozens of launches to be able to re-use a Falcon9. They'll get there eventually.
Nobody thought they'd get Falcon 9 to launch, and they did. Nobody thought they'd get Falcon 9 to land, and they did. Nobody thought they'd be able to re-use a Falcon 9 enough to make it worth the investment, and they did.
Doesn't mean they'll succeed, but it does mean they have a good track record.
Well, they've produced the first, (and only so far), truly reusable rocket.
And starship is slated to be the second.
To add on to what everyone else is saying, compared to the Apollo capsules, Starship is fucking HUGE. Apollo 11's capsule was 10 feet tall by 13 feet in diameter. Starship is 180 feet tall not including the launch vehicle.
Edit to add: Mercury was literally just an ICBM with a dude strapped on top, with Saturn V being based on that design. We're only now beginning to make designs that are actually made just for space travel.
Also... Starship absolutely got into orbit, and could have completed the orbital insertion part of an Apollo style single use mission.
They just haven't finished troubleshooting the re-use part yet. It's already more powerful and cheaper than a Saturn V.
Other commentor answered very well. I'll just add that if China or Russia starts sending successful ships to the moon/mars and/or starts making real steps for a moon base, then you can bet your ass the US government will pour all their resources into our space program. In other words, the Cold War boosted the space program in the 60s because Russia scary. During "peace-time", the US government purposely under funds the living shit out of NASA. That's why private corporations are doing it now, like SpaceX.
I agree, but I'm afraid these days they'd just farm it out to a private business instead of doing it themselves with the goal of doing it right like they did in the 60's. Today they'd overpay some billionaire hugely for worse results because greed for profit = overcharging and substandard parts and oversight.
I don't know for sure but if it started to suck after 1980, it was Reagan's fault.
We privatized anything related to space exploration.
Easy answer. Far less money is being given today to NASA:
Further, that NASA budget includes all the extra planetary science happening (multiple Mars rovers, Deep Space network, LEO space station operations, deep space probes like DART, Juno, OSIRIS-REx, etc, plus all of the atmospheric flight stuff like the low noise supersonic flight experiments. This also includes *all of SLS* which is a SECOND rocket being made for Moon exploration.
To answer your second question: yes, reuse is worth it. We didn't do it during Apollo because it would have been even more expensive. Because we didn't have it, any flight was just as expensive as the first. So we had to stop going unless the crazy amount of money would stay, which it wouldn't.
Plus SpaceX squanders far less money than the contractors that have sucked off the government teat via NASA for 50+ years.
Those bloated companies are part of the military-industrial complex and finance lobbying to push projects (especially cost-plus) which they can then "compete" for.
Don't get me wrong, I don't blame NASA, this is a problem of politicians and grubby bastards in companies like Boeing, General Dynamics, etc. NASA is controlled by congress and whoever is providing financing - the shuttle development history demonstrates these problems very clearly (competing requirements from Air Force, NSA, etc, who were providing funding).
At a high level, NASA, (like many government projects) have traditionally used more of a "Waterfall" project management approach, while SpaceX has used an iterative Agile-like approach. This means SpaceX can be more nimble while learning along the way, enabling them to change direction when they discover a fundamental misunderstanding. The first launch of Starship demonstrates this approach perfectly.
NASA was also different in 1960's.
People said they could have meeting with supplies and make changes in the meeting. Now it seems like everything is a huge ballache to change anything.
Safety, scope of mission, budget
The first moon missions were extremely risky. Many people died during development and/or during those missions. As NASA evolved, they reprioritized safety and that changed the demands of the vehicle.
The scope of the missions are also different. The first moon missions were, mostly, about just getting there. Taking moon samples back and doing science experiments were limited. The mission now is for a larger group of people to stay on the moon for week/weeks.
Budget has been a huge issue since the 80s. Once the allure of new and exciting space things died down after the first landing on the moon, public perception and federal budgets got moved to other things. The reason NASA is using the SpaceX rocket isn’t because they couldn’t make something better. But SpaceX has done a lot of the development on their own dime. Getting a moon-worthy rocket without an additional decade of funding and research ensures reasonable timeframes for the new moon missions.
Remember how Reagan and Thatcher told your parents that private corporations are (somehow) "more efficient" than state run organisations?
Yeah... they lied.
They *are* more efficient.
1) They are more efficient moving money from the bottom to the top and making investors and CEOs rich.
2) They are more efficient at making the minimum product for the price while suppressing labor, reducing customer service, and enshittifying the product as the lifespan of the company progresses in order to do #1.
Well... since you put it *that* way - I'll just have to concede.
The technology from the Apollo program is gone. It was destroyed and can be developed again but that takes time. Now couple that with the fact that private companies are trying to create a completely new tech with reusable rockets that return to earth intact and you have several engineering hurdles to say the least.
I have to admit it's a beautiful thing seeing it happen! We're going to get there again! We must explore space or become stagnant as a species.
What do you mean the tech was destroyed?
There was no need to produce the items in question, so we lost the expertise and the underlying manufacturing facilities/experience/etc. Stuff like: The company that made the windows no longer exists. The company that made the panels still exists, but they can no longer source the strictly defined % alloys as *that* company no longer exists. Stuff like that.
Also to add to the other person the literal paper files were accidentally destroyed when they were in storage in NASA.
Several reasons.
1 - SpaceX is a startup company. They run on venture capital, and unlike NASA who gets a big bag of taxpayer money, SpaceX has to promise new investors something better every year. And since SpaceX hasn't come close to turning a profit, they need to do it by making spectacle. Launching Rockets is spectacle. Traditional companies can take their time to get it right, but SpaceX can't draw in the venture capital they need to survive based on one succesful launch every other year. But they can get money with slightly less shitty failures.
2 - SpaceX is using an entirely new type of engines, burning liquid methane instead of kerosine or hydrogen, and making rocket engines is... well.. rocket science. The problem is mostly that it's really really hard to get engines to relight when you don't have gravity, and especially hard when it's methane you're burning. This is why Apollo used hypergolic engines (fuel that will burn when it touches, instead of needing to be lit) for everyone but the main launch.
3 - SpaceX only got the contract for the lunar lander because the head of the lunar lander program, Kathy Lueders, gave them (and not the other parties) a private call to tell them the exact budget available. Then she awarded the contract to SpaceX, for being the only party to submit a bid within the budget. (Source: https://ecf.cofc.uscourts.gov/cgi-bin/show_public_doc?2021cv1695-77-0 the court opinion where they spell out this was legal, and say nothing on wisdom or ethics, pdf alert). Incidentally she now has a cushy and well-paid job at SpaceX.
4 - NASA recently paid a second party, blue Origin, to also develop a lunar lander, so feel free to take that as you will. It's probably not a sign of trust in SpaceX... so I'm willing to say that point 5 is that either SpaceX is shit at this (unlikely, since Falcon 9 is pretty awesome) or they're just not taking it seriously.
Point 1: SpaceX's entire development philosophy is "test early, test often and learn from failures". This is a much quicker pace than simulating every imaginable failure scenario and leads to faster progress in development. With the Falcon 9, that process proved wildly efficient and successful, culminating in a launch vehicle so reliable that it's cheaper to insure a payload on an F9 that already has multiple launches under its belt than a brand new booster. And they're turning enough of a profit to develop the Starship largely on internal funds, seeing how the early Raptor flight tests were before the HLS contract.
Point 2: Just adding, the Raptor engine is the first full-flow staged combustion engine to ever get off a testing stand and actually fly. The engineering complexity of these things is on the level of the Shuttle's RS-25.
Point 3: SpaceX were the only ones with more than designs and mockups to present, and they had a reliable track history from working with NASA on the commercial resupply and crew projects. And I see no problem with awarding a contract to a bid that actually fits into the budget.
Point 4: Multiple options was always part of the plan. NASA wants redundancy, so that if one of the providers runs into problems, the other provider can continue (and perhaps even take up the slack) instead of everything coming to a grinding halt. For a perfect example, look at the Shuttle and Commercial Crew programs. The Shuttle got grounded and since it was NASA's only manned launcher, they had to bum rides from the russians. In contrast, the CC contract was awarded to Boeing and SpaceX. With Starliner's continued issues, SpaceX has picked up the slack and fulfilled more than their initial contract in launches, instead of NASA having to bum rides from the russians again. The initial HLS contract was supposed to go to two providers, until the budget got cut. Blue's bid was always the favorite for the second pick.
This is a catchy statement, not an actionable philosophy. There's many ways to do it, and it's entirely possible that SpaceX is doing it poorly.
There's a lot of value in brainstorming every imaginable failure scenario. It's industry standard to do so in fact with HAZOPs. There's failures that you may not necessarily see in testing -- especially those that are rare but catastrophic. This is a field that should be acutely aware of that given past events.
There's also a right way to do testing and a wrong way to do testing. You typically consolidate tests and do several at a time, depending on the stage in the project. And you don't typically risk precious equipment in doing so.
From the sounds of it, they don't have a robust safety program, and they're hemorrhaging money and resources through poor testing philosophies.
There's a point at which you learn more from actually building something and putting it through its paces than simulating. It's a tough balance to strike , no argument there. Simulating until you've covered every conceivable edge case and failure mode is ludicrously costly and time consuming. Relying entirely on yeeting shit and seeing how it fails risks missing the edge cases. But so far, I've seen little reason to doubt that SpaceX has found a working balance between simulation and practical testing. They're certainly progressing faster than the industry historically has and the F9 has had no failures, even partial ones, in over 200 flights. That's a track record that most launch vehicles can't meet. It's definitely possible there's a 1/1000 flaw in the Falcon 9, but until it actually happens and they lose a rocket and/or a payload (gods willing it won't be crew), it's nothing but a hypothetical "but what if..." scenario.
Is it? Starship has been in development since at least 2012-ish (as the "mars colonial transport" or "its" or "bfr" or a few other names). It hasn't done a succesful mission yet. ULA's Vulcan was anounced in 2014, and it works just fine. So I don't really think it's actually faster or better, but it IS more showy.
No they're not.
SpaceX has reported 1 quarter in 2023 with positive cashflow of 55million dollars out of 1.5b in revenue, and has then gone completely silent again. SpaceX has done 33 commercial launches and 63 starlink launches. Some very basic math shows that there is no way Starlink can pay for that (63 launches times 62 million per launch divided by 2.6 million subscribers = 1500$ per user per year, which is every single subscription dollar). So two-thirds of SpaceX launch income comes from a company that itself is unsustainable and operating on purely on venture capital.
Absolute and complete lie. Its exactly the opposite. SpaceX did not, and still DOES NOT have a solid design or mockup of HLS. Dynetics and Blue Origin had both.
The problem is that SpaceX had a bid at the same level of the others, but they lowered it when Kathy Lueders gave them a call (and not the other parties) to lower it. This is spelled out in NASA's own document: https://www3.nasa.gov/sites/default/files/atoms/files/option-a-source-selection-statement-final.pdf (note how it's fully written in the first person by Kathy herself). This is primary basis, massive favoritism by a NASA employee who then immediately started working for SpaceX. I'll leave the motivations of her doing these things as an exercise to the reader.
When the other two parties found out, they offered not just to match SpaceX bid, but beat it. Of course, since Kathy Lueders didn't show them the same favoritism, they didn't find out till after the bidding process closed.
No, the contract stated that anything between zero and three were options, based on funding. They said the goal was two, but then budget was reduced. Nobody was told this. The number of contracts was also reduced to one as a result. Nobody was told this. And then Kathy Lueders gave SpaceX a call, and not the others, to share this information.
The first time Starship was spoken of was in 2012, yes. The very first idealistic designs of it. The design that's actually being tested is from 2018. So 5 years to go from "Alright, this is what we're gonna do" to full stack flight testing. Roughly on pace with their previous rockets, the Falcon 1 and Falcon 9 took about 4 years.
Blue Origin had (and still has) no experience with human-rated capsules. Their proposed lander had to be assembled in lunar orbit or launched on another SLS. The Dynetics lander was over its own mass budget. It was literally too heavy to do the job it was being proposed for. Meanwhile, SpaceX proposed a derivative of what they were already working on. Blue and Dynetics had no practical development done on their landers, they would've relied on the HLS award to even get started on actual development.
SpaceX's bid was just under 3B. Blue Origin bid at a bit under 6B. Dynetics wanted 9B. This information is freely available online. SpaceX was also given the least in design development funding, with 135 million versus Blue's 579 million and Dynetics' 253 million. It's not terribly shocking that a company with a good track record and the lowest bid wins a contract.
They needed a lander contract. The entire Artemis project was already fucked when it comes to the timetable, but delaying the HLS contract would've made things even worse. And when the budget got cut, they negotiated with the one bidder who was deemed most likely to still get the job done with the lower budget, as opposed to the other two whose bids were wildly over what NASA could give them. SpaceX bid at 2.94 billion and the final award was 2.89 billion. Again, BO bid 6 billion and Dynetics bid 9 billion. Losing 50 million is an easier pill to swallow than getting half or a third of what you need.
Seeing how SpaceX had neither a design or a mockup, they had no development done on their lander. Their lander STILL does not exist, not even as a mockup. They are STILL behind Blue Origin today when it comes to the lander. Blue Origin entered the HLS bid with a full mockup, that was compatible with existing technology. SpaceX entered with no mockup and entirely undeveloped technology, but was somehow judged equal (By Lueders) to Blue Origin based on
AFTER being told to do so. That's the entire problem. Blue Origin and Dynetics both came forward and said they'd gladly match that bid, but since they didn't get the special information that was only given to SpaceX, they couldn't know this. BO also clearly said they would gladly develop out of pocket, but they weren't given the special info. Because, again, the lady currently enjoying a cushy, well-paid contract at SpaceX, only gave new information to SpaceX.
Let me repeat that one more time: The contract was unawardable to two of the parties, because those parties had NOT been given the unknown information that Lueders gave to SpaceX.
SpaceX didn't need a mockup to present. They had prototypes of the base vehicle and a proposal for necessary modifications to perform the contract duties and an established track record of developing ambitious rocket engines and launch vehicles. BO had bits and pieces of other things they were gonna bolt together and a pretty model of how it'll look like, we swear, scout's honor. But if you're talking about the Blue Moon that eventually won the secondary bid, that's not what they initially proposed.Blue Moon Mk2 is a variant of a lander that's been in development since 2016, so two years longer than SpaceX's Starship prototypes. The one that's planned for a lunar landing this year, Blue Moon Mk1, isn't the one they bid for HLS. It's a robotic lander, smaller than the HLS's Mk2. So fancy that, they won a HLS contract when they bid a variant of something they were already working on, much like SpaceX did. And remember, BO is developing a lander. SpaceX is developing a fully reusable super heavy lift rocket, an interplanetary transport craft and a lunar lander as part of the same package.
Finish reading my post. SpaceX's initial bid was 2.94 billion and the final award was 2.89 billion. Again, they agreed that they can do the job for 50 million less than what they originally bid. BO's and Dynetics' proposals would've suffered a much larger hit. And sure, BO got the secondary contract for 3.4 billion, after rethinking their entire proposal. So why did they not submit that one in the first place? If they had, they might have gotten a similar call.
In the early 70s it was a risky and expensive one-time deal. Starship is doing it sustainably and will completely revolutionize space travel. I wouldn't say they're struggling they're just still developing it.
The capabilities of starship are orders of magnitude more payload and for orders or magnitude less money at the same time.
Turns out it's a bad idea to totally scrap a billion dollar rocket every time you use it.
modern companies use "Agile" development
I may have missed it in another comment, but I believe part of it is the cost of lives. During the space race someone dying would've just been part of the risk. Now we are using more automation and a human fatality might risk a company's ability to continue its pursuit.
Musk wants to reinvent the wheel, essentially
Because politicians cared more about it back then, nowadays they're too concerned about making the other political party "lose" than doing stuff to actually benefit the country's citizens
Apollo was a huge government project. It was affectively a military, science, geopolitical and political project that had a lot of backing by the public.
I would argue Apollo is the great project ever and it's kind of unfair to compare anything to it.
But the real crux of this matter here is if you get your info from Lemmy or reddit (and not one of the places filled by experts). It's full of "Lol Elon bad" circlejerking. "Haha the rocket blew up they so stupid". It's really cringe. In fact SpaceX, NASA, the FAA, astronauts who will go on the ships, other space companies, experts they all expected this to happen. This is the plan. (Though the FAA did have some issues).
Ignore the "Elon is an idiot" memes and what you actually find is Elon's SpaceX is probably the greatest rocket company in the world and all rocket agencies including governmental ones though that SpaceX has already achieved was impossible. People don't like seeing that and outright ignore the facts.
Anything could go wrong with this project but I don't think people would be overly concerned if rockets failed all throughout this year. (But it is expected to be better than that.)
Lost me at the second paragraph, Elon most certainly can be a complete moron while SpaceX remains a competent launch provider with, but to ignore his track record and business dealings in considering HLS would be a lapse in judgement.
Aside from the man, the plan of starship is vague at best, and given 2 billion in public funds is planned to be spent on starship this year alone, I would certainly like to know more details.. as NASA does too:
20 launches, up from musks initial 8, will be needed to fuel the craft
Contracts have deadlines and astronauts need assurances
If NASA is to a point healthy critique is considered cringe, then I doubt we'll be on the moon for long. Sure there's some rashness, but in the publics eye, do you think Apollo could've succeeded if they had dismissed hardware failures as RUDs?
Apollo 1 nearly ended the program, yes it was the deaths of those astronauts that prompted that, but its necessary rigor that prevents another such accident. An inherent con of the trial-by-fire method SpaceX has had is the potential to miss something that wasn't an immediate issue. This can be mitigated, but is a valid source of concern for the engineer.
I however am not nearly qualified to make a call. But I feel as though this video from the channel SmarterEverDay (whose family was involved in Apollo) sums up a set of valid concerns that I think anybody with interest in these this should at least hear.
I want us to go back to the moon just as the next person, but remember: Apollo cost some $200B in todays money, part of that cost was the extensive checks needed to avert tragedy, we must be sure we're not cutting that its only a natural concern. And we can't make heroes of men while we're at it, nobody is infallible, if the proposal is solid it will be the one to take us regardless who's running the show. Or if its not, we cannot afford to make mission proposals personal.
You're being intentionally obtuse. I'm obviously not calling NASA cringe and that's not even remotely implied.
NASA is running the project, set the tenders and observing the suppliers. No one would expect anything else. Smartereveryday was largely on about culture at NASA from what I remember from that video. That and the lack of hypergolics. If NASA wanted hypergolics on the moon they could have put a requirement "must use hypergolics on the moon". But they didn't. That's why all the relighting tests are being done. If the engines relight to the needed reliability then everything is fine, they have set the standards.
The Apollo project was tested live. They did all the lab tests but the real world tests were largely done with people in them. Apollo was risky as fuck and would never ever be allowed to happen now. I think some of the astronauts thought there was as high as a 50% of death. The fact you don't know how risky Apollo was to the astronauts shows you don't know much about this because you are using the safety of Apollo as a benchmark. Look I love Apollo but it wasn't a high benchmark of safety.
With things like this. Testing to failure is pretty norm. NASA uses falcon 9 rockers for crew which was largely tested the same way. They obviously have faith in SpaceX because they out humans in their rockets.
Well you offhandedly gave "elon bad" memes precedence over actual critiques being offered, nobody who actually cares about this moon thing gives a damn about elon memes,, so I expect to discuss the merits of the mission plan off its merits alone.
It may be a long watch but please actually watch the whole thing, he's very well spoken and ultimately optimistic (as am I) about going back. But I am certain he had more to mention that just hypergolics. I can list a few
If these are "intentionally obtuse" points, well then welcome to aerospace engineering, its called *rocket science* for a reason.
And Destins point about the culture? People aren't speaking their critiques when they're most necessary to hear, people are afraid to speak. How does that contribute to a program which may or may not have flaws (that could be remedied), when no flaws are at least pointed out? Well look at Boeing for one.
I mentioned Apollo 1, right? Im pretty sure I mentioned Apollo one and how they perished on the pad and it nearly stopped the program. Now if you're going to be intentially obtuse, then I bid you a good day.
Haha lol you are being intentionally obtuse again. I never said anything bad about NASA I never said they was being obtuse and I never said they were being cringe. You are arguing at a wall because I never made those points.
A lot of people say a lot of stupid things about Elon and SpaceX and that vastly out weighs the actual issues with this project. Of which there are real issues. Everything NASA says is assumed to be a valid issue. Again intentionally obtuse because I'm not arguing anything else
I watched that video when it came out and I can't really be bothered watching it again.
Haha good day mate. You are trying to make a conversation out of something I'm not saying, you're not worth talking to. If you want an imaginary conversation please have it with yourself.
Work on that reading comprehension, it'll do you well.
Maybe it's because Elon is too busy rattling off on Twitter and building trucks that rust after a couple of days.
SpaceX is not getting people into space, and certainly not to Mars. It'll be a long time before we have someone who's level-headed enough to make such a feat happen again. Even if resources were more limited back in the late 60's, what made stuff work is people knowing how to use the tools they had. Now, we have all this stuff, and nobody with the knowledge to give it any use. It *is* rocket science, and big, fancy computers aren't going to do anything if you can't write the software for it.
Meanwhile spacex is getting people into space...
reagan
Yes, that's the correct answer
