Part of article’s argument, can be summarised as “US Congress spends over $10 billion a year on grandiose and unachievable Martian vision-imagine what we could achieve if they gave that to JPL for robotic missions instead”. But that isn’t how Congress works. If they cancelled all expenditure on human space flight, they’d be unlikely to redirect any more than a fraction of that to robotic science missions. Instead, it will probably go to a new weapons system, or Medicare, or farm subsidies, or whatever. Spending it on human spaceflight likely even has indirect benefits for the robotic program-some NASA resources are shared by both programs, and taking away the human spaceflight component of their funding may threaten their overall viability, and hence their ability to serve the robotic programs
The article gets the numbers right but the human part absolutely wrong. I'd love it if humans were the kind of creatures that could make big advances by taking them one small boring step at a time with no unachievably ambitious end goal driving them forward, but that's absolutely not how it works.
The first advances in science were made by people trying to get rich turning worthless metals into gold. A lot of computer science grunt-work in decades past was done by or funded by people who thought they could build C-3PO.
Reasonable people who avoid likely financial ruin, who don't dream of building impossible machines or visiting other planets, simply don't take the risks needed to make actual technological leaps. Reasonable scientific goals that can't make headlines don't get billions from Congress.
We're not capable of building Mars colonies any time soon, that's true, but who knows what we'll invent as we blunder our way in that direction nonetheless?
Actually - It doesn't get the numbers right either. If you look at the first reference, "[1]", the author says:
"I’ll justify this figure in detail later on. For now, consider that each SLS launch costs $4.2B, and that developing just the Orion space capsule has cost $20B. The ISS, which is functionally close to a Mars transfer vehicle, has so far cost $250 billion."
With absolutely no regard for the massive cost per kg to orbit improvement being achieved by new space companies (SpaceX, RocketLab, etc.)
The author has cherry-picked his facts to fit his opinion.
> The first advances in science were made by people trying to get rich turning worthless metals into gold.
And the planetary motions were discovered by somebody trying to prove that the 5 planets all fit inside a babushka doll of the 5 platonic solids. This says nothing of what would happen if these scientists had different creeds or different goals. Most scientific discoveries are indeed very boring. Vera Rubin discovered dark matter while trying study the rotation curves of spiral galaxies, a very simple and very down to earth goal that lead to a remarkable discovery. At the same time Jane Goodall’s big creed was that maybe it is OK to empathize with the individual animals you are studying.
Grand goals are neither necessary nor sufficient for making scientific advancements. And while some goals might be useful, others are just as likely to be a major distraction. There is reason to believe that a human mars landing falls in the latter category.
Love your perspective. It reminds me of the technological advances from the space race to the moon as well. We aren't taking casual trips up there ever, but the tech that came from it was revolutionary
i feel like this is all propaganda to convince tax payers to fund this stuff. it's like we never invented anything worthwhile at all if it wasn't used for war or space. maybe we should just try? try spending some money on good for a change and we'll see if good comes out of it.
Yeah, the obvious reason why funding spaceflight yields useful technology is that we also fund e.g. laser technology. We can fund science research without also spending billions of dollars going to the moon.
If it is propaganda, it is to detract from the fact that we could actually be on Mars already, if we hadn't spent a Trillion dollars a year bombing the shit out of everyone for the last two - or so - decades ..
People tend to forget that we are still murdering each other over this planet.
Getting to Mars would either be a solution to that problem, or just an extension.
I guess, therefore, it matters who gets there first.
The Apollo program was insane for the 1960's. It was announced by JFK just one year after NASA's first successful manned space rocket. Engineering was still primarily done with pencils and slide-rules, the US had only just achieved widespread household electrification, and the first supersonic flight was only 15 years earlier.
NASA's budget during the Apollo era was about 10 times that of the Manhattan Project, about 1% of the entire US government budget. It could have turned into history's largest money incinerator if things had gone bad organizationally. I can't really think of any project like it that has been attempted before or since--not at such a huge scale and on such a short timeline.
The Soviet Union's own moonshot ended up a gigantic disaster, and it was only diligence and commitment (and luck) at every level of NASA that allowed them to succeed given such a monumental goal. But the goal itself was very close to madness.
"The Soviet Union's own moonshot ended up a gigantic disaster..."
For All Mankind on Apple TV+ has a lot of fun extrapolating from the premise of the Soviet moonshot succeeding and beating the US to the moon. Then presenting an alternate history of how events unfold differently because of it.
Basically extrapolating the insanity of the Apollo program up until the present day, as USA and Soviet Union continually try to one up each other in the space race.
Beside that, it did not seem to result any direct advancements in technology. We can't even build a Saturn-V any more. (But we can build SLS and Falcon Heavy though, after 50+ years.)
It did result in a number of smaller-scale advancements across the field, AFAICT, from radiation-hardened electronics to material science.
It's not that we can't, we just decided to redirect those resources to other areas (i.e. the Space Shuttle) and now those designs are very out of date.
It's like saying we can't build the pyramids anymore just because we can't build them the exact same way the Egyptians did. Is the goal to get to the moon or is the goal to build a faithful replica of the rocket along with a faithful replica of the tools that built the rocket?
We developed a particular pinnacle of tech and lost it through disuse. This happens in aerospace and high-end weapon-making areas regularly, because the runs are small, and much of the knowledge and technology is uniquely purpose-built, with thick layers of secrecy protecting the know-hows.
Speaking of military technology, humans lost the secret of "Greek fire" [1], which apparently was a medieval form of napalm, not extinguishable by water. All the current knowledge of chemistry did not help restore the recipe yet (because history studies have a smaller budget than the actual military, of course).
We haven't lost the ability to fly to the Moon, of course, because the principles remain the same, and the technologies advance. But we had to build completely different rockets, not reusing many, if any, bits of Saturn-V.
> It did result in a number of smaller-scale advancements across the field, AFAICT, from radiation-hardened electronics to material science.
Has it though? These are requirements for our normal earth orbit satellites, surely these would have advanced at a similar pace without the moon mission.
> We can't even build a Saturn-V any more.
Isn’t that a demonstration of the fact that the moon mission was an engineering dead end?
It succeeded because the Saturn V had enough heavy-lifting capablity that we could do the entire mission with one launch vehicle for the complete round-trip.
It was the power of the Saturn V being sufficient to get us out of the Earth's gravity well, plus the cleverness of the Lunar Orbit Rendezvous mission plan that allowed us to pull it off. Once those two things were worked out and understood, the rest was just a matter of executing. But it was pure happenstance that the laws of Physics and the Earth/Moon orbital mechcanics lined up to make it possible.
And the Saturn V only had enough lifting capacity because the Air Force had issued a requirement to Rocketdyne back in 1955 for an engine powerful enough to deliver the huge H-bombs in use at the time. Within a few years, nuclear weapons researchers had figured out how to build lighter weapons so the huge F-1 engine was no longer needed for ICBMs, but fortunately it was ready for use in the Apollo program. The USSR had nothing comparable.
I doubt anyone is actually going to “shoot prematurely for the Mars”. I expect what SpaceX is going to do, is once they get Starship up and running, and tick off some intermediate goals such as Artemis III and DearMoon, they’ll start launching demo Mars missions-no crew, but demonstrating some of the technologies a crewed mission will need-and NASA will probably pay for some of it. And that’s likely to take a lot longer than all their optimistic estimates suggest. But they’ll continue to dangle those timelines in front of everybody to create buzz which increases the odds of Congress/NASA paying for some of it. SpaceX might be a bit less risk-averse than NASA, but no way are they sending humans (even privately) to Mars unless they have reasonable odds of surviving, and there is a lot of further technology development and demonstration required to have reasonable confidence in that.
Like with reusable rockets before, its very important to a do real world demonstration that this is possible. This way a lot of the naysayers blocking Mars related projects in other companies/organizations/countries will be much less of a problem.
And in general will make more people consider to get involved as this is real now, not another power point, computer model or study.
i think musk has basically said he doesn't mind risking/losing some lives. and people have volunteered. whether or not the world allows him to actually do that is another story though
Musk is prone to speak in a somewhat hyperbolic fashion, and may well be more risk-averse when it actually comes time to actually decide whether to put human lives at risk, than he is when talking about that decision as an abstract future. It also isn't entirely up to him–it is also what the rest of the SpaceX executive team feels comfortable with (especially Gwynne Shotwell), and also the comfort level of the regulators and lawyers.
Even NASA "doesn't mind risking/losing some lives", in that while they drive the "probability of loss of crew" as low as feasible, they never can get it to zero. Possibly, a private SpaceX mission might have a higher go/no-go threshold for that probability – but if it adds up to (say) 50%, I really doubt they'll go ahead with the mission, they'll likely instead delay so they can invest further engineering resources in reducing it to a more reasonable level.
Haha, not really - the original Apollo program was reasonable - lets doe a low Earth orbit space station or two, build some space infra, improve and ideally reuse launchers...
Then Kennedy came with "LETS DO A LUNAR LANDING LIKE RIGHT NOW, LOL!" & then got himself killed so it could not be taken back.
What followed was an ultimately successful mad dash with great emphasis on cost-is-not-an-option which did bring us some nice inventions but did not really help to build any real space infra or to lower the launch costs.
And arguably also entrenched the bad idea that space needs to be horrendously expensive and always will be. Not really, until you are on a mad dash with a singular unrelated objective.
But hey, it might still be useful experience next time a killer asteroid or hostile aliens show up.
As long as people need to worry about things like their own financial ruin, need to worry about their investors each quarter, people aren't going farther than the earths orbit, and if they do, it will surely be a one way ticket to death. Doing it right now its like asking someone to play an impossible chess game where your side only has pawns and you lose $100 billion everytime one is taken.
I can give you a concrete counterexample to that. The Perserverance rover is carrying an entire experiment (MOXIE, which makes oxygen from CO2) whose only purpose is to serve a future human mission. NASA is encouraging more of this stuff, and it means automated Mars rovers will go to the boring sites that we need to prep rather than look at the phenomena of highest scientific interest on Mars.
That said, I'd love to hear what people who work at JPL and NASA have to say to your point.
Oxygen production is also useful for sample return missions.
The biggest flaw with the rovers is that they’re terribly slow, so they can only explore a small range around a landing site. If they could cover even 100km/day, which seems plausible on RTG or solar power, we could explore many sites.
Probably an unpopular opinion around here, but honestly I think defense, healthcare, and food security to be more practical than human space exploration. I know that major advances in computing were made during the Apollo mission, but that was 60 years ago. What have you done for us lately?
Maybe Starlink ? That already showed serious defense implications for example. And while not in-your-face visible I'm sure all the remote sensing sats launched in the last two decades improved our weather forecast, disaster monitoring and agricultural production significantly.
Yeah, but those aren't related to human space exploration. Not saying we should get rid of the space program 100% - just reduce it's cost by cancelling all the human spaceflight projects.
there are too many existential threats when looking on a long enough timeline to not justify making humanity interplanetary. It just has to happen at some point and i'd like to get moving before i giant asteroid comes hurtling at the planet, or the yellowstone volcano decides to erupt.
I see this as an AM/FM problem. If one of these disasters happen, then we should rely on "actual machines" to mitigate or avoid them, and not rely on "F*ing Magic" like interplanetary colonization.
I'm not saying we shouldn't try to expand what's possible with "actual machines", but that should be up to academia - and they're pretty clear that human space exploration isn't worth the money.
Yeah, but that's kind of how human progress works. For each Edison or SpaceX which successfuly commercialised a technology, there are Nicola Teslas and Apollo programs which did it way before both the tech and the society were ready for it, in a one-shot way that's a bit difficult to replicate.
What did Tesla do that was so far ahead of time that was difficult to replicate? Surely Tesla, together with Westinghouse, is why we have AC power distribution and polyphase AC motors and neither of those things are difficult once they are properly described.
Usually governments have some kind of plan how much they want to spend on science. A big, but ultimately useless project can kill the funding for a lot of other research.
It's silly to do things just because they are hard. Extraordinarily silly.
What Kennedy did not say, was "it's just hard enough". Hard enough that we can pull it off, and the Soviets can't, and the world can see that. Much better to gain a space upmanship victory than a shooting nuclear missile victory.
Now we are in a different place. Well, maybe not for too long, you never know. China has its own space ambitions, and military ambitions too.
But just doing hard things for the sake of doing hard things makes no sense.
