|
| ▲ | voidUpdate 5 days ago | parent | next [-] |
| According to wikipedia, the entire cost of the saturn v project was US$185 million, equivalent to US$33.6 billion today. That's from R&D to all launches |

| ▲ | ralfd 5 days ago | parent | next [-] | | You mis-copied the numbers for one launch. Wiki says: > Project cost US$6.417 billion (equivalent to $33.6 billion in 2023) > Cost per launch US$185 million (equivalent to $969 million in 2023) That a manned Apollo mission would/did cost under a billion dollars (todays money) is surprisingly cheap. A single Artemis launch using the Space Launch System (SLS) costs an eye watering $4 billions. Different metric: > [1966] NASA received its largest total budget of $4.5 billion, about 0.5 percent of the gross domestic product (GDP) of the United States at that time. Using that metric NASA yearly budget would with todays GDP be $150 billion dollars. | | |
| ▲ | wat10000 5 days ago | parent | next [-] | | Part of the SLS cost comes from trying to save money. Yearly budgets are kept low, which spreads out the work over a long time. This makes everything cost more, but the politicians only care about the yearly spending. SLS is also a pretty weird design due to reusing Shuttle components for a completely different kind of launcher. This saves development costs (maybe) by using existing stuff that has already been developed, but the unsuitability of those components for this system increases per-launch costs. Once NASA runs out of old Shuttle engines, manufacturing new ones is going to cost $100 million apiece if not more, and each launch needs four of them. It was OK for Shuttle engines to be expensive since they were supposed to be amortized over hundreds of flights (and in practice were actually amortized across at least tens of flights) but now they’re being used in expendable launches. If Starship even comes remotely close to its goals, an entire launch will cost less than a single SLS engine. | | |
| ▲ | thesmart 5 days ago | parent | next [-] | | I had understood that reusing shuttle parts was more about keeping congressional districts (that make the parts) happy, and thus securing votes for funding. | |

| ▲ | mikepurvis 5 days ago | parent | prev | next [-] | | Some of this was the overall urgency of the 1960s space race, that people were motivated to cut through red tape and get it done, and I know it's also argued that modern safety standards and requirements around supply chain, real time monitoring, system redundancy, etc all complicate things and raise costs. That said, it would be interesting to have someone really knowledgeable go over what it is that Artemis has and Saturn V didn't, and then break them down and assign each an approximate proportion of the cost delta. | |

| ▲ | anonymars 5 days ago | parent [-] | | No need to be condescending when communication is ambiguous. Your question can be better phrased as, "How much did it cost for Saturn V to reach the point where it could successfully orbit?" which I assume means "how much did it cost up to and including Apollo 4?" | | |
| ▲ | dylan604 5 days ago | parent [-] | | Wouldn't the cost of all of Mercury and Gemini missions need to be included in this as they could not have Apollo without the others first. | | |
| ▲ | terminalshort 5 days ago | parent | next [-] | | And then we also need to add the costs of the V2, because surely we wouldn't have had Mercury and Gemini without the V2 first... and of course we wouldn't have that if the Chinese hadn't developed the first rockets in the 13th century, so we need to figure out their development costs. Where does it stop? | |
| ▲ | thesmart 5 days ago | parent | prev | next [-] | | So you think SpaceX isn't building on the shoulders of giants? There are teams of incredible engineers working there because NASA paved the way. | |

| ▲ | dylan604 5 days ago | parent [-] | | Do you think they would/could have built the Saturn V without building the other engines first? | | |
| ▲ | anonymars 5 days ago | parent | next [-] | | I think as phrased this is going to get way too pedantic. But I think it raises a larger point which is worthy to consider. Presumably what we're trying to get at is, in broad strokes, "is Starship more cost-effective to develop than Saturn V" (and I assume the follow-on for that will be to compare the "NASA approach" vs the "SpaceX approach") But you raise a good point in that the baseline playing field is completely different. The existing knowledge each program started with, be it in materials science, understanding of rocket combustion, heat shield technology, electronics, simulation ability, you name it, it's completely different. So we can find and pull out whatever numbers, but I don't think it's possible for them to say anything meaningful for comparison on their own. | | |
| ▲ | fluoridation 5 days ago | parent [-] | | >but I don't think it's possible for them to say anything meaningful for comparison on their own. It depends on how different they are. Saturn V was launched 13 times in total. Starship is already 75% of the way there and hasn't orbited once. Ignoring R&D and just going by launch costs alone, that's USD 4B (2025) to orbit 1 Saturn V, vs USD x to orbit 1 Starship, where x >= 1B. | | |
| ▲ | dylan604 5 days ago | parent | next [-] | | > Saturn V was launched 13 times in total. Starship is already 75% of the way there Apollo 1 - lost on the launch pad, crew killed. very bad
Apollo 13 - major malfunction causing loss of mission but crew saved. very not bad Starship - 10 launches 5 failures. No crew ever so that pressure is also not comparable. Are we really claiming Starship has achieved 75% of the results of Apollo? That's absolutely ludicrous | | |
| ▲ | fluoridation 5 days ago | parent [-] | | Starship is 75% of the way to 13 launches. That's just mathematically correct. | | |
| ▲ | dylan604 5 days ago | parent [-] | | And is absolutely useless. Apollo 9-17 went to the moon with human occupants. All but one put men on the surface of the moon. They all returned to Earth with zero fatally exploding ships. Not one of these triumphant 75% achievement in launch numbers would have had a surviving human. Apollo had 0 practice runs. Starship is nothing but practice runs. To equate the number of launches to something so drastically different is just an exercise in futility that I can only assume you're trolling | | |
| ▲ | anonymars 5 days ago | parent | next [-] | | > Starship is already 75% of the way there and hasn't orbited once Read it as "Starship is already 75% of the way to that cost and hasn't orbited once" (you seem to be in agreement) | |

| ▲ | Sparyjerry 5 days ago | parent | prev [-] | | Starship has already reached orbit many times but places itself on a suborbital trajectory to intentionally test re-entry and landing which it has done successfully several times. | | |
| ▲ | fluoridation 5 days ago | parent [-] | | Wrong. Starship has yet to orbit the planet. Certainly not "many" times, considering this is only its tenth flight. | | |
| ▲ | Sparyjerry 4 days ago | parent [-] | | They've already demonstrated they can orbit, they just choose not to. Reaching orbit and orbiting the planet are two different things.

| ▲ | fluoridation 4 days ago | parent [-] | | >Reaching orbit and orbiting the planet are two different things. LOL. Are you serious? To reach orbit: to reach a horizontal speed such that the spacecraft can complete a revolution around the celestial object while in free fall, without having to execute any additional maneuvers. Starship has yet to reach orbit. The reason doesn't matter. It hasn't done it. |

| Adding to previous comment, looks like the cost per launch when the system was up and running was ~1billion USD inflation adjusted. I'm going to assume Starship will beat that easily. |
| |
| ▲ | staplung 5 days ago | parent | next [-] | | Maybe, but remember that getting astronauts to the moon and back took a single Saturn V launch but with Starship, it will take (at least) 10 flights for refueling, possibly as many as 20. So each launch has to be much cheaper to beat Saturn V for the full mission. Nobody but SpaceX knows how much each Starship test costs but the estimates online range from $50 million to $200 million. Presumably, whatever the actual cost, they're more expensive right now while they're redesigning bits and doing custom, one-off work for each flight but it has a long way to go to beat Saturn V for the full mission. | | |
| ▲ | briandw 5 days ago | parent [-] | | A starship mission to the moon will land over 100tons of cargo. Saturn V could get roughly 5tons to the surface. Its an entirely different class of operation. | | |
| ▲ | thesmart 5 days ago | parent [-] | | That's LEO, not to lunar orbit and entry. Saturn V had a maximum lift capacity of 310,000 lb (140,000 kg) to low Earth orbit (LEO) and could deliver approximately 50 tons (45,000 kg) of payload to the Moon. | | |
| ▲ | boxed 4 days ago | parent [-] | | Well... no. The PLAN for the Starship lander is to have 100tons of cargo. That's why it takes so many refulings. |

| |
| ▲ | loeg 5 days ago | parent | prev [-] | | Looks like Starship test flights are already beating that $1 billion per-launch cost (I'm seeing estimates in the $100-500 million range), and they'd like to get the marginal cost down to ~$10 million. | | |
| ▲ | anonymars 5 days ago | parent [-] | | I'm confused -- how is it meaningful to compare the cost of Starship test flights with operational Saturn V missions? | | |
| ▲ | fluoridation 5 days ago | parent | next [-] | | There were no Saturn V test flights like Starship is doing, that I can find info on. Wikipedia lists 3 tests before Apollo 4, which was the first full launch. | | |
| ▲ | anonymars 5 days ago | parent [-] | | From context I interpreted GP to be somehow concluding that Starship is "cheaper" (these test flights are "beating" the price tag of the Saturn V launches), I'm gently pointing out I don't think that is a reasonable conclusion to draw based on empty suborbital test flights vs. taking humans to the moon and back | | |
| ▲ | fluoridation 5 days ago | parent [-] | | It would seem no one has the information I originally requested. All we have to go on for Saturn V is a per-launch cost where we don't know what's included. I agree it's an apples-to-oranges comparison, but it seems to be all we have. |
|
| |
| ▲ | boxed 4 days ago | parent | prev [-] | | The test flights include R&D. The ~1b per flight of Saturn V was excluding R&D when the program was churning along. I guess you could argue that it's never meaningful to compare anything that isn't a commodity though, which certainly isn't the case here. But I find that silly. | | |
| ▲ | anonymars 4 days ago | parent [-] | | That's not what I'm saying. We are comparing 1 billion per operational Saturn V flight to...what? There are no operational Starship flights to compare with. What sense is there in comparing the cost of manned flights to the moon and back with unmanned suborbital test flights? | | |
| ▲ | boxed 4 days ago | parent [-] | | Saturn V did have at least one suborbital mission with Spacelab though. So not as hard to compare as you say. | | |
| ▲ | dragonwriter 4 days ago | parent [-] | | Spacelab was carried on Shuttle flights, Skylab was launched on a modified Saturn V. And it was low orbit, not suborbital. |

| How does that matter? It's doing a thing already done nearly 70 years ago but at its own pace. I bet it will get to the moon cheaper, too, and the Muskonauts will use less expensive lenses than Hasselblads to take photos. |
| |
| ▲ | fluoridation 5 days ago | parent [-] | | Starship isn't exactly the same as Saturn V. It's bigger, for one. The reason why it matters is that efficiency matters. It's fine if it takes longer, not so much if it costs way, way more, especially if such a huge rocket has limited applications. And as I understand it the consensus is that Starship (or at least a fully-loaded Starship) will never go to the Moon. Once it's in orbit it takes like twenty refueling launches and space rendezvous to fill it up again so it can make the transfer burn. In other words, it's never happening. | | |
| ▲ | stetrain 5 days ago | parent | next [-] | | I think that understanding of the consensus is incorrect. The mission plan for Artemis 3 is that a specialized Starship upper stage will be refueled in LEO and then transfer to lunar orbit where it will wait for astronauts arriving on SLS/Orion. Yes the mission profile is more complex, but that complexity can mostly be settled before the astronauts launch on their mission. NASA seems to think it is a viable plan which is why they selected SpaceX to execute that part of the mission. | | |
| ▲ | fluoridation 5 days ago | parent [-] | | Wikipedia: > After a multi-phase design effort, on April 16, 2021, NASA selected SpaceX to develop Starship HLS and deliver it to near-rectilinear halo orbit (NRHO) prior to arrival of the crew for use on the Artemis III mission. The delivery requires that Starship HLS be refueled in Earth orbit before boosting to the NRHO, and this refueling requires a pre-positioned propellant depot in Earth orbit that is filled by multiple (at least 14) tanker flights. I stand by what I said: not happening. I'll believe it when I see it. Can you imagine if to make a sightseeing trip to another city you had to stop in the middle of the highway and then make 14 round-trips with a second car to fill your first car back up? I can't imagine why someone would approve this plan, other than corruption. | | |

| ▲ | dmbche 5 days ago | parent | next [-] | | False dichotomy - the mission profile dictates the refuelling station and all that, but it never was the only option. Somehow we've decided we needed to be able to do lots of trips to the moon for Artemis, but it's not clear to me that it's such a precious golden oportunity and warrants this spending/impact on the environnenent. We didn't get to the moon with a refuelling station did we? How come we need one now? We're really seeing 15 starship launches per moon trip as reasonable, rather than just building a single trip program? The mission itself is nonsensical. The problems are stemming from the SLS, I'll find a link to a relevant source. | | |
| ▲ | DarmokJalad1701 5 days ago | parent | next [-] | | > We didn't get to the moon with a refuelling station did we?

| ▲ | stetrain 5 days ago | parent | prev [-] | | The Apollo missions landed two crew members in a tin can with extreme limits on what weight they could bring with them in either direction. A single trip launch will always be constrained like this due to the tyranny of the rocket equation. A modular mission system with multiple launches is the best way to expand capabilities and enable things like landing larger payloads for more advanced or long-term missions. | | |
| ▲ | slipperydippery 5 days ago | parent | next [-] | | IIRC, the expected return payload for this is lighter than Apollo. In no small part because they're dropping all their return fuel and their entire return vehicle into the Moon's gravity well, rather than leaving it in orbit. Subjecting themselves to extra abuse from the good ol' rocket equation. One of many wacked-out things about the plan. | | |
| ▲ | stetrain 5 days ago | parent [-] | | The vehicle that returns to Earth is Orion which stays in NRHO and does not bring its fuel to the lunar surface. Return payload constraints are probably from using Orion as the return vehicle. Mass to the surface is much higher than Apollo since that is launched separate from the crew. | | |
| ▲ | slipperydippery 5 days ago | parent [-] | | I thought the return vehicle was a to-be-developed direct-return vehicle from both SpaceX and Blue Origin (both got contracts, and supposedly both's versions will fly)? [EDIT] Apparently there are multiple plans involving even more spacecraft, because why not I guess? It's as you describe for Artemis III, but then gets way more complicated with Artemis IV, involving more spacecraft for some reason. | | |
| ▲ | stetrain 5 days ago | parent [-] | | As far as I know all of the known Artemis mission profiles only use the lunar lander to shuttle from NRHO (lunar orbit / gateway station location) to the lunar surface and back. All crew return is planned to be done with Orion for now. NASA has optioned an additional lander from Blue Origin but that would be taking the same role as SpaceX's lander, shuttling from lunar orbit to the surface and back to lunar orbit. |

| ▲ | slipperydippery 5 days ago | parent | prev | next [-] | | The mission is wildly more complicated than the Apollo missions. There's a whole oddball-orbit space station that has to be placed as a way-station, for one thing, and none of that's happened yet (remember how long it took to build the ISS?). Also, landing all your return fuel instead of leaving it in orbit, so a way heavier lander (with a smaller return payload than Apollo!), which is a pain in the ass. Multiple space ships launched by different rocket systems involved. The SLS still has to be finished for it to go forward. Orbital refueling of large fuel tanks is a hard problem that remains unsolved, and this goes nowhere without fixing that. The contracts for the return vehicles are disturbingly light on parts about making sure they can reliably work, including surviving re-entry. I'm with you. Not happening. We're more likely to come up with a totally different, simpler plan, and do that instead, before this happens. | | |
