It's crazy the US could soon have up to 5 different spacecraft/launch systems that can take humans to orbit with 2 more in development:
Falcon 9 + Dragon, SLS + Orion, Atlas V (Vulcan Centaur) + Starliner
Close to orbital payload launch, likely human rated in the future: Vulcan Centaur + Dream Chaser, Superheavy + Starship
Under development: New Glenn + Space Vehicle (?), Neutron
> It's crazy the US could soon have up to 5 different spacecraft/launch systems that can take humans to orbit with 2 more in development
We had a launch system that could take humans to the moon in 1972.. haven't had one since. Maybe we will get another one in our lifetime, if it is even possible.
Is there much practical reason that requires sending people to the moon still? Modern robots are cheaper and can perform science more effectively than any human
Distributing human populations to ensure survival. With current tech the lunar colony couldn't be self-sustaining but the ideal is that humans would be able to propagate and sustain themselves outside of Earth so that a single event couldn't end human civilization. Also creating a jobs program that will produce the technology necessary for a lunar colony will improve materials science, medical understanding, logistics.
We could also learn to live within the means of our ecology.
That wouldn't prevent one off extinction type events like asteroids. We can improve our understanding of ecology by trying to design such systems for lunar colony artificial biospheres.
I do agree that we should better manage our impact on the only system that we know works.
This is the lamest of all excuses.
It's a very unlikely for one, we haven't had an extinction asteroid in 65 million years. Detection and mapping is very good today, and they're relatively simple to deflect given even with current technology, and a long enough lead time. Obsessing about asteroid impact is just an excuse to engage in fantasy.
But saying "We can improve our understanding of ecology by [designing] artificial biosphere", is just the chef's kiss of bullshittery. It's like saying, that we can understand the ocean by getting a fish bowl. Not exactly, and it certainly won't teach us anything about the actual biosphere. Instead, all you'd learn about is atmosphere scrubbers and water reclamation.
No. We can't detect asteroids coming from the direction of Sun. Just ask people of Chelyabinsk, Russia. [0]

Pssst. The Earth moves. It’s not always on the same side of the sun.
I recommend taking a look at the article I shared. It might help you gain more insight on the topic, rather than continuing to post critical comments without all the information.
[I hope an LLM made it polite enough]
This was a bit more than a hundred years ago. https://en.wikipedia.org/wiki/Tunguska_event
I'd say that such an event happening over a populated region of the Earth would be pretty bad. It's worth a bit of investment.
Here's what would happen if Tunguska happened over Paris, using a mid-range estimate of its magnitude: https://nuclearsecrecy.com/nukemap/?&kt=30000&lat=48.8583&ln...
Worth the investment of an extraplanetary colony? Because that’s the investment we’re talking about.
He said "like astroids". Quite frankly we don't know how frequent extinction events happen. We've had nuclear weapons for less than 100 years, and have a couple of close calls[1] already.

1. https://en.wikipedia.org/wiki/1983_Soviet_nuclear_false_alar...
We could just build giant bomb shelters. It’s cheaper, holds more people, and doesn’t require nearly the investment in a completely closed ecosystem. But that ain’t sexy.
If you want something that uniquely requires leaving the planet for somewhere you have truck in literally everything except rocks, you’re pretty much limited to the sun becoming a red giant. That and gamma ray bursts. That’s pretty much it.
and what is this simple method to deflect a large asteroid headed for Earth?
A gravity tractor is the simplest solution with enough lead time. It's theoretical, but doesn't involve any exotic technology or materials.
Essentially you have a spacecraft park itself beside an asteroid. It's gravity will minutely change the asteroids trajectory. With enough lead time that's all you need. Since you're not blowing up, or applying a large focused amount of energy to the asteroid it doesn't matter what the targets composition is. You won't break it up.
https://en.wikipedia.org/wiki/Gravity_tractor
To be kind of blunt, even an extinction-level asteroid hit with near-total biosphere destruction is probably still more conducive to human life than any other planet or satellite in the solar system, as evidenced by the continued existence of at least a few forms of life past the extinction event. And many of the events people worry about are far less destructive than even that (nuclear winter, for example, would probably roll Earth's climate back to pre-industrial temperatures, maybe as far as Little Ice Age, which is, uh, nowhere near extinction-level threat to humanity).
It's also worth pointing out that it's possible to do closed ecological studies without the expense of running it in space (e.g., Biosphere 2). The only thing you need space for studying in that regard is "what is the effect of non-1g environments on biological forms?" (to which existing studies suggest the answer is somewhere between "bad" and "horrible").
They are in 0g environments presumably having 1-6th isn't as bad and there might be ways to prevent/mitigate those issues.
This sounds like the harder problem.
No, it's merely incredibly difficult. Sustainable living off Earth is far beyond that.
Humans definitely can't leave. Humans are even less well suited to interstellar travel than they are to living at the bottom of the ocean, something they also don't do and have no idea how they could ever do.
So, with tremendous effort humans could visit one of their neighbouring planets. All of these planets are terrible. Mars is by far more hostile to life than anywhere humans have even visited, let alone had a permanent settlement. But we could do it. To what end?
Live here, or die here, those are your options and you should get used to it.
To have the species survive if anything ends all life on Earth - apparently not a priority for you but it is for those that enjoy humanity existing.
Also to explore and learn more about the universe we live in. Do you truly not see value in that? Have you never left the city/state/country you were born in?
Nothing the universe has thrown at Earth in the past 3 billion years has been capable of ending all life. And nothing that could happen in the next million years seems possible of doing that either.
When we say life on earth we mean human life and civilization. Prokaryotes, while alive, are not really what people mean. Yes they would survive asteroids, nukes, possibly nanobot swarms.
It's difficult, but I don't think it is _that_ difficult. Ecologies, like any living systems, can self-heal and regenerate. There are practices that allows us to tap into that regenerative power as societies. They may not happen fast relative to our individual human lifespan, but 50 years is more than enough time to restore wastelands or reverse desertification.
I don't have a good answer to how sustain an economy based upon mining, refining, and manufacturing things out of mineral resources. Many of us have gotten used to modern conveniences (at its own cost related to mental and emotional health, and social cohesiveness). I think what most people balk on are on the perception of having to go back to barely surviving off the land, or having to alter lifestyle. Lifestyle may have to change, but the same regenerative power of ecologies also gives us significantly more resiliency.
Why do anything at all? Who are you to dictate to others what their options are?
That would be easier if we could move polluting industries off Earth.
Maybe we can find alternatives besides those industries.
As far as cleaning up pollutants themselves, there are some amazing work by Dr John Todd for cleaning up pollution. Two examples of his work — a system capable of breaking down DDT within 40 days. Another where he cleaned up a superfund site that had all ten of EPA’s top toxic pollutant list.
Self-sustaining human colonies in space or on other celestial bodies are very distant dream, probably it will take several centuries or millennia to happen. The main reason is human body: we haven’t figured out reproduction in low gravity yet. Unless some fascist state will do it, we will never experiment with it until full confidence in safety for the mother and the child.
It’s easier than you think to get 1g of gravity in space.
It's a very distant dream that will always remain distant if we don't work on it. We have a lot of things to test before we get to testing the gravitational requirements of human reproduction. As it stands, we don't even know our basic gravitational needs. All we know is that 0g is too low. It's entirely possible that it turns out we can function relatively fine at something low but non-zero, like 0.1g.
I don't think distributing within the solar system is going to do much for us. What takes out the Earth will probably take out everything else - we'll be backstopped on Earth for centuries after we have spaceborne civilization.
I think opening up a new frontier however, is valuable - in fact specifically, the transition which would be good would be to move heavy industry out of the biosphere entirely. You can imagine a nearer future where a place like Earth is treated as the paradise it is, and the idea of polluting it when we have all the rest of the uninhabitable space of the solar system to do that in is thought of as ludicrous.
And this isn't really unreasonable - beyond a certain point, the resource and energy availability of space is far greater then the places we can reach despite the advantages of the biosphere - whether we do it by robots or with manned exploration.
There's a zeitgeist change that I think would accompany having enough people working frequently in space: where its a couple of degrees of separation from someone who's looked at the pale blue dot and gone "you have no idea how valuable this is" (I do think we should have a program which sponsors any world leader who wants to on a trip around the moon: send the people making the big decisions out past the dark side, where the thing bubble of air, steel and alloy is the only thing keeping them alive - might not always work but at least then we can know they've had the opportunity for that perspective).
Instead, launch sealed, frozen embryos into orbits of various bodies in our Solar System — bury a few on the Moon.
I think a long term view is it’s the basis for building heavy industry in space as it has a lot of natural resources that can be exploited industrially and escape orbit velocities are much less from the moon than earth surface. This eventually leads to a general space infrastructure. If you believe the end of humanity is on earth then this probably isn’t convincing. Folks like myself believe we are inexorably driven to spread life as a function of what life is and we have no meaningful choice but to keep going.
But as long as some subset of humanity believes in this humanity will keep investing in it. Not everyone has to be aligned and we can have many priorities at once, not the least of which is robotic science which I only see as mutually exclusive as long as there’s not plentiful private investment, which there is at the moment. I don’t see robotic exploration as suffering in the build out of extremely low cost launch capability and a general space infrastructure including moon infrastructure. I see it benefiting enormously as the costs and risks drop significantly.
If we ever get to heavy industrialization of lunar resources, how are we going to deal with the CO2 footprint of rockets?
A spacex falcon 9 contains ~as much fuel as a 747. Note: fuel, not fuel + oxidizer
Edit: falcon 9, not starship
Source?
I get Starship 34,000,000 kg + 12,000,000 kg vs 747 ~200,000 liters ≅ 150,000 kg, or about 1/300 th of what Starship holds.
Oh shit I'm sorry I am so wrong. I had calculated falcon 9. Thank you for the correction
There are a million viable (and often quite fun) answers here, but one is really kind of funny. What do you get when you mix oxygen and hydrogen? Water? No, of course not! You get rocket fuel! Seriously. Liquid oxygen + liquid hydrogen is a common, and highly effective, fuel that's been used for various engines such as on the Space Shuttle Main Engine.
Rockets can also be carbon negative in another way. A rocket that uses less than 50% of its fuel getting to orbit would be carbon negative, because it's spending less than 'x/2' fuel to go burn at least 'x/2' fuel away from Earth. Factor in some of the fuel coming from carbon neutral sources, and it quickly becomes quite easy for a rocket to be carbon negative.
In theory it's possible to make a carbon-neutral methane rocket based on atmospheric CO2, though that depends on how completely the methane can be burned.
https://en.wikipedia.org/wiki/Substitute_natural_gas
I don't remember exactly but a rocket launch has the carbon footprint of ten American citizens produce annually.
The flow of mass would be the other way around. Lunar regolith has every element embedded in it and there’s little need to bring anything but bootstrapping -to- the moon. Return to earth from the moon wouldn’t be CO2 producing anywhere but the moon.
You'd be moving other polluting industries off-Earth, thus offsetting the footprint of things that cannot be done without said footprint.
Mass drivers.
Bragging rights (ostensibly "practical" in a geopolitical, soft power projection sense)
Didn't we get to brag about it already? The value of continuing to have the capability seems to be outweighed by the costs of maintaining the facilities and equipment
You don't get much bragging rights for being first to plant a flag on the Moon once China has a continuously manned outpost there.
Establishing a permanent presence on the moon would be a stepping stone to further exploration of other planets. (Mars in particular.)
Since its only a 3-4 day trip, with transfer windows every month (and non-optimal ones essentially constantly). resupply missions and rotating astronauts/personnel are going to be much easier. Much less of a gravity well to deal with.
The plan would be for in situ resource extraction and manufacturing. With enough of a human presence, projects like local construction of spacecraft become feasible. And something like a mass driver would be much more feasible on the moon. A big enough one and you're even considering interstellar probes ...
It would require a consistent, sustained effort. But not astronomical in US budget terms. Maybe $20-$30 billion/year (about of 3-4% the defense budget)
Anything beyond Earth orbit requires either multi-stage expendable rockets, which isn't economical for supporting a moon base, or in-orbit refueling that has better economics than expendable rockets, which depends on cheap rapid reusability. If you can't land, refuel, and fly without refurbishing the launch system, rocket engines, etc. you can't ship fuel to orbit cheaply enough to justify in-orbit refueling.
Starship is a vastly better attempt at more of these goals than STS. But if it misses cost, or payload, or reliability goals it won't solve this problem. It is even possible that it will take too many attempts in which a ship and 39 engines are expended to even get close.
Or we can get the fuel from the moon. The moon has water ice, which means it has hydrogen and oxygen, which you can use as rocket propellant.
It looks like the RTT is 6 minutes (more or less depending on orbit) for packets send to mars, but despite that it does seem like the easier option yeah.
Not really accurate at all.
The lowest the RTT gets is six minutes but that is a brief period every couple of years. The longest RTT is 45 minutes.
Even 6 minutes makes any kind of tele-operation infeasible and require system to function autonomously. This restricts the kinds of science that are currently possible.
"can perform science more effectively than any human" is very disputable.
If they are so much better, why does anyone get up off their couch and do field research? Just let the robots do it.
Besides, it's human nature to explore, in person. As George Mallory said, "Because it's there."
For off planet research: because ( https://xkcd.com/695/ aside ) we don't care if the robots "die". Human space exploration has an enormous amount of overhead to keeping the humans alive at all; even the sensors humans bring with them are compromised by having to be operable in a spacesuit.
Not saying that there isn't value to sending humans into space - it's just that that value isn't in gathering data for science, other than on the astronaut-subjects themselves.
Robots aren’t performing science, they’re doing one half of one step of the scientific method: collecting data in an experiment. It’s humans doing all the rest.
I would imagine (a) keep watch over the lunar atomics and (b) fend off PLA officers stationed there permanently after Chang'e-42.
Penal colonies of course!
This is a common misconception. Modern robots are very limited in their capabilities, out of necessity. Mars is a great example. Perseverance has the most capable drill of any rover, and it can drill up to 2.4 inches deep. [1] And these drills are used extremely sparingly because they tend to break rapidly, like any sort of moving part. Perseverance's top theoretic speed is around 0.07mph, and it's a speed demon compared to prior rovers. [2] Same reasons - the more you move the more things break, and the nearest repair shop is pretty far away. The first humans on Mars will almost certainly learn vastly more in a week than we've learned in 60+ years of probes and rovers!
Beyond this though (and also the survival aspect as others have hit on), I'd simply mention the inspirational aspect. Many who lived through the Moon landings (as well as those who did not) see this as humanity's greatest achievement. And I think this sort of stuff helps to create a better future for a people. When asked what they want to be when they grow up, the most popular choice for American children today is a vlogger/YouTuber, the least popular is astronaut [3]. In China, the answers are completely reversed. Who's going to have the better generational outcome in 30 years?
But of course this isn't just for children. So many people just seem completely devoid of hope and optimism for the future. And that's completely understandable the way things have been going for many decades now. But show literally anybody this video of the Falcon Heavy landing [4] and the first question you will always get is, "Is that real?" People just can't even believe what we're achieving, and I think doing even more of this, on a much larger scale, and making it all the more visible would really improve so many lives, and likely the entire country itself. Just read the comments to that video, to see how it impacts people, and those are friggin YouTube comments!

It makes more sense to have a permanent human presence on the Moon than to aim for Mars.
The Moon is both very near and very easy to communicate with so it is the perfect first place to learn about building a "colony" before moving on to Mars.
Not much point sending robots to go look at Moon rocks if there's no pretext of sending people there. I mean, you could make some PhDs out of it I'm sure, but would that be worth the public expense? I don't think so.
Humans won't survive long-term without colonizing other planets and/or star systems. There are existential threats already in motion besides climate change; Earth won't have any surface liquid water in about a billion years. While there is several times more water underground than on the surface, that may also not be locked away well enough for when the Sun becomes a red giant 4 billion years later.
Yes, humans living on other celestial bodies is a goal in itself, expanding us beyond Earth and a few people in LEO.
Cities on the moon and Mars are a reasonable and achievable goal. There are resources which can much more easily be exploited with real people on premise, some people will want to live in different environments, there are opportunities for sport, entertainment, tourism, and plenty of industries which will be much more effective with skilled labor on site instead of meticulously planned missions which often fail and if they don't spend a whole bunch of effort overcomming the basics of operating.
All of the science returns of the robotic missions to mars in the past three decades could have been done by a geologist in a space suit with a rock hammer in 15 minutes, and probably done better. Robots really, really suck.
Also many people see the whole point to be expanding people out into the cosmos, not the science.
Why does someone always do this in a thread about space stuff?
Without fail there's always some negative Nelly who already knows the answer to their downer question.
We get it. You don't care about space shit, most people don't. But why go derail a thread about a space accomplishment with negativity?
Is there much practical reason for that?
I wouldn't go that far, but we already had humans on the moon so we can get away with robots doing the science now. I still think sending astronauts to mars would speed up research, for example.
The big one that robots can’t do is studying human biology in space.
How do we fare long term on a foreign body? What does trauma medicine look like? How do we accommodate the diseases and disabilities that frequent our non-astronaut grade population? Is gestation, birth and development possible in low gravity? Et cetera.
Then Moon provides the easiest place to do this at scale by virtu of being the closest place to Earth with in situ resources.
This comment is an invitation to an uninformative comparison. Apollo was just barely able to take a crew to the moon and back, with many expendable stages, using 5% of US GDP to do it. Almost all the value in Apollo is indirect value in the form of technologies developed for Apollo.
Why replicate that? Indeed we should ask: Is there a goal to value, other than the obvious "the Chinese would get there first if we don't?"
A lunar "base" would just be a vastly more expensive ISS. We will discover that lunar regolith is a bigger nuisance than floating boogers in the ISS.
The mission goal was to land a man on the moon and return him to earth safely.
Where’s the barely? What would you have done better?
I would think barely here means, that there were quite a lot of incidents and with some bad luck, none of the astronauts would have come home.
It was still a great accomplishment, so I would not use barely, but technically it is correct I think. They spend great effort, to just make it to the moon, which was the goal, to beat the sowjets. And that succeeded. No great safety margins, not much room for error - barely.
What I meant is that the multi-stage Moon rocket, the capsule and command module, and the lander and ascent module, were just barely within the realm of the possible as dictated by the rocket equation. And, as you mention, the risks were just barely acceptable.
Source?
We can design—and are designing—automation into a lunar base in a way we couldn’t with the ISS.
That sounds really interesting, but web searching mostly brings up very old research. Do you have a link for any of the up-to-date work on automating the base?
Saturn V was ridiculously expensive [1] and very unsafe.
Apollo was built to get to the Moon fast half a dozen times. We’re building more ambitiously today.
[1] https://en.m.wikipedia.org/wiki/Saturn_V $1.5bn in 2024 dollars
Von Braun was asked if the Saturn V was safe to launch. He asked six of his engineering reports, each replied nein. Von Braun replied that the Saturn V had six nines of reliability.
Golf clap for that one
That's literally the SLS.
SLS is too underpowered to send Orion into lunar orbit, let alone Orion + a lander.
It would probably become a lot more possible if we could get this "SLS/Orion with frickin' Starship as a lunar lander Rube Goldberg machine" monkey off our backs.
Interesting and very readable elaboration of this snark: https://idlewords.com/2024/5/the_lunacy_of_artemis.htm
I just want to live long enough to see a ship, intended for long-term use, assembled in orbit.
I just want to live long enough to see Venus terraformed into an ocean and forest covered paradise.
Need a planet spinner if that's going to happen.
A lot of mirrors in a 24h orbit might be easier.
Still, even then it will take, what, about a century to get rid of the CO2? (Does it even count as an "atmosphere" at ground level, given that it's past the critical point and the distinction between liquid and gas phases no longer exists?)
If going that far, use the sunlight for power / in space solar ovens. Just make sure to limit how much power goes to Venus because that will increase the net energy in that envelope.
One of the options is to use the mirrors to boil off the atmosphere, the other is to keep the sunlight away for so long the atmosphere almost entirely condenses and can then be paved over; either way, it was a long wait.
You can't "boil off" the atmosphere. You need to accelerate the gas molecules past the planetary escape velocity, otherwise they'll just cool down and drop back onto the surface.
There's no realistic way to evacuate that much gas (the surface pressure on Venus is almost 100 atmospheres!).
One option is first to cover the surface of Venus with water, by first creating giant orbital mirrors to let the atmosphere to cool. Then you can sequester the carbon dioxide as elemental carbon under the water surface. Oxygen released in the process will be naturally consumed by all the underoxidized minerals present on Venus.
Venus hardly has any water, as it has already lost most of its hydrogen into space (due to its very weak magnetic field): https://en.wikipedia.org/wiki/Venus#:~:text=The%20solar%20wi....
Doing it to heavier gases on human time scales is a whole other scale of problem.
The idea I've heard is to dump many gigatons of hydrogen into the atmosphere to make H2O and elemental Carbon via the Sabatier reaction which will occur immediately with Venus' temperature. This gets rid of some of the CO2. The water will be part of the atmosphere, the carbon will rain down on the surface of the planet.
There will still be a lot of CO2 around though. Now you shade the planet with a giant sunshade and the atmosphere will cool down to the point where CO2 will snow out as dry ice after a couple decades of cooling. What you'll have left is a layer of carbon, followed by a layer of water ice, followed by a layer of dry ice. The atmosphere will be 2 - 3 times as dense as Earth's with almost entirely nitrogen gas. You use autonomous robots and mass drivers to collect and launch the excess dry ice into orbit.
Once you've got most of the CO2 ice out you remove the sunshade and the planet will very quickly thaw out. The planet will be covered mostly in oceans at this point with a thick nitrogen and CO2 atmosphere. At this point use genetically modified algae and microbes which, using the plentiful sunlight, can quickly convert the high CO2 atmosphere into oxygen and organics for the soil. The planet may still need some minor solar shading to keep the temps down until the CO2 approaches earth levels. Introduce Earth life to build a natural biosphere and voila! You've got a whole new Earth whose biosphere should be able to sustain life for millions of years!
Velocity in a gas is a distribution; raise temperature and increasing fraction exceeds escape velocity.
This is why Earth has ~ no hydrogen or helium in the air.
"Realistic" for values including "let's build a mirror the size of a planet, in space, and keep it together for centuries".
It's currently scifi to send more than a mere few tons total mass that way, and mirrors wouldn't even survive decades, so "realistic" is a bad criticism.
Oh, I'm sure it'll take at least several decades and more likely centuries but getting a new planet would be worth it. Seems like a harder project than terraforming Mars but in the end it would be a nicer place in my estimation. With only 7% less gravity, nearly as much surface area and without the dim sun that Mars has I think I'd rather live there.
Yeah seems like with our current physics, almost everything can be cheated out, except mass and gravity. There's no other solid Earth-sized mass now other than Venus so it may be our only real potential second home.
You can cheat gravity with a centrifuge; when the alternative is on the scale of "let's freeze or boil away Venus's atmospheric", building a city-sized rotating cylinder to live in is trivial.
But that new planet has the exact same fate as Earth in that the Sun will eventually devour it. The only way for the species to survive longer than the sun is to find other planets around other stars at different stages of their life cycles. Yeah, I agree. Expecting the species to survive that long is a bit optimistic.
We have billions of years before that happens. We're talking about things we can do in the next hundreds.
I've always loved the idea of floating habitat in Venus' atmosphere but the temperature remains the largest part of the problem.
Kurzgesagt has a good youtube video of the idea. It's wacky and unrealistic in some ways but doesn't violate any laws of physics and seems feasible to the sort of advanced civilization we humans hope to have in many decades.
In discussions I've read on planetary climate modelling one idea is that if Venus had an atmosphere like Earth's but 50%+ thicker and an ocean covering 70% of it (like Earth) you'd get an ideal situation. Because of the strong sunlight and slow spin you'd get a tendency for thick storm clouds continuously covering whatever part of the planet was experiencing mid-day, shielding the planet from the strongest and hottest rays of the (60% stronger) sunlight. The warmth would convect to the night side keeping things from getting too cold. Depending on the conditions it's possible that below-freezing temperatures wouldn't even be common in the depth of the night.
The long night seems like a problem for life but forests already thrive in the warmer parts of the near-arctic. And in times past even Antarctica had tropical rainforests despite experiencing a polar night. Another idea I had was building a ring around the planet of dark material, perhaps of left over carbon after we cleaned up the CO2 rich atmosphere. The dark ring would provide shade to certain parts of the planet during the day and would reflect light for the long night.
Sounds like a sure fire recipe for a (permanent?) super intense electrical storm in right that spot.
Might make that specific latitude uninhabitable due to the planet turning. Though it could be worth the trade off, due to there being a bunch of available land on the planet in other latitudes.
If you have some truly huge arrays of super capacitors such a permanent electrical storm might even be useful. :)
Sounds sorta fun IMO. With the slower rotation of the planet and the rotational winds being slower maybe there would be less lightning. IDK though, I'm talking out of my ass.
I've read about many terraforming ideas such as these, and I really think they're kinda pointless, because it would probably be MUCH easier to just build O'Neal cylinders. With those, you can create artificial habitats with the exact parameters you want, instead of trying to change an entire planet so be somewhat habitable by humans.
Clever. You seem to want to live on forever...
Interesting. And I'm thinking I want to see a permanent lunar base but also, "Where does it end?"
Humans walked on the Moon in my lifetime. I should be contented with that.
I'm apparently younger than you, and humans have not walked on the moon in my lifetime. I'm discontented by that.
Same, I’m terribly disappointed that I can’t simply walk on the moon. Parents generation really dropped the fuckin ball there eh
I don't recall a ball, but they dropped a feather and a hammer (the gravity experiment).
Golf ball
https://en.wikipedia.org/wiki/Apollo_14#Lunar_surface_operat...
The 3rd para talks about the (golf) balls.
Spherical hammer in the vacuum is a ball.
Really probably your grandparents or great grandparents depending on your age. Most Americans born after the moon landings had boomer or gen-x parents. All the men who walked on the moon and the majority of those in high office until roughly the 1990s were silent generation, the GI generation or older. They’re the ones who had the power to keep the space program going but didn’t. Once your parents had significant influence the Apollo program was long gone, the know how to build the hardware was gone, they would have had an even harder time than us rebuilding it because the commercial impetus wasn’t there and we didn’t yet have insane internet billionaires competing for launch contracts.
https://amgreatness.com/2024/06/03/the-destructive-generatio...
In between the Greatest Generation and Gen X - "Baby Boomer" was a name, but Destructive Generation seems to fit pretty well.
Soon there will be no living humans who have walked on the moon :/
There’s no money or geopolitical strategic importance in it, and “we” didn’t go to the moon, a saber-rattling warmongering government did using oodles of tax money and repurposed ICBMs (Mercury/Gemini).
I think perhaps Dr Strangelove is more educational about the cultural climate around the Apollo program than almost any other media.
Hopefully with vastly reduced cost to LEO it will be put within the reach of normal people who aren’t engaged in the dance of WW3 nuclear brinksmanship.
It's wild to think this is true for anyone under the half century mark.
I want to live long enough to see a viable test of larger spaceships that could send humans to Mars. I really want to live long enough to discover evidence of at least microbial life elsewhere in the solar system - Mars seems like the obvious place we can reach with a good chance for it be possible. I know there's amazingly water vapor around Europa, that's so much more remote.
I think about 30 years should lead to more exploration of Mars, and maybe multiple landers andn robots getting there from here, maybe even a return trip. (human travel to Mars feels so far out, even if Starship works out in the next 10 years).
Well, isn't it what the ISS is?
No, it has no propulsion system. That is the difference between a ship and a station.
It does have thrusters used for orbital correction about monthly, (and maybe dodging debris here and there,) but it's fair to say that system is not for taking trips or anything.
Even less than that - most of the station-keeping is supplied by visiting spacecraft; the thrusters on the (ancient, failing) Zvezda module appear to be rarely used.
My mistake!
angry Cygnus noises
I think there are thrusters on the Russian side of the station. They aren't large but they move the stations orientation for docking sometimes. (And cartwheels for fun and horror)
Personally, I want to live long enough to hit life extension escape velocity. :)
Yeah we bemoan how short-sighted people are, but that's because we only live for a handful of decades. Think of the kind of progress that we could achieve if people were free to follow their dreams for centuries, alongside the kind of respect for the life and nature that would be necessary to live as a citizen of the world for that long.
Or, immortal Joseph Stalin having breakfast with immortal Richard Nixon, while deciding who gets sent to the gulags today.
That's a rather weird person to pick, even considering that it's probably a Futurama reference...
Nixon - now more than ever.
True, today time is the greatest equalizer. Even the rich and powerful will eventually kick the bucket and leave the future for others. If life extension takes off, the rich and powerful may live forever, while the less fortunate may still be mortal.
How long do you think for them to get to the point where they can carry all the raw materials up there?
That’s probably just a handful of starship trips of cargo
I want to live long enough that I can go and see space without having to give someone a huge amount of money
I just want to live long enough to see a human walk on Mars.
That is exactly what the cislunar transporter is going to be.

I'd settle for seeing my children grow up at least a bit!
What’s stopping you from helping to build it? Jobs in space tech exist. They need smart motivated people.
IMO, this one is the least likely.
There are a lot of problems that need to be over come for Dream Chaser to be crew rated. And AFAIK, they aren't getting NASA money to do it.
Intriguing. Can you elaborate?
The big one off the top of my head:
Dream Chaser flies in a fairing for aerodynamic reasons. In order to fly crew (so that the vehicle could have a working launch abort system), they'd need to figure out how to fly without a fairing.
Naive question: Planes and helicopters do not have the ability to safely eject passengers mid-flight. We largely accept these conditions as a risk of those modes of travel. Why is LES/LAS a unique requirement for space shuttles?
That's a fair point, although my understanding is that parachute systems for small planes are becoming more common.
My view is that flight rate is the fundamental issue at hand. Airplanes and helicoptors fly many orders of magnitude more than these capsules, which means we know they are many orders of magnitude more reliable.
They've also generally been through a long process of refinement - the original airplanes were extremely dangerous compared to modern variants.
Additionally, aircraft can afford to have a lot higher margin of safety baked in to them. Because of how high gravity is on Earth and the nature of the Rocket Equation[1], it's just not possible to have a lot of margin in rockets of capsules. They need to be extremely svelt to launch at all.
And lastly, we have experience with human spacecraft without an LES/LAS - it was the Space Shuttle. And it killed 14 people - easily the most dangerous spacecraft ever created. No one has any desire to build on that particular legacy.

No, it means we have orders of magnitude more reliability data. Same result, different point.
We have enough data to know that rockets are not as reliable as airplanes.
Also worth noting that test pilots of experimental aircraft generally wear parachutes, at least for higher risk tests. This includes tests of commercial aircraft.
Planes and helicopters do not frequently fail by exploding, but rather things like engines failing. An engine failure, even if it’s the only engine in a given airplane or helicopter, does not automatically involve a deadly crash. Airplanes can glide, frequently for very long distances, and helicopters can use the air moving across the rotors to effectively “glide” down. It’s not always possible, but they do have inherent redundancies that rockets necessarily do not.
Helicopters are actually even safer than fixed-wing airplanes this way: as long as the rotor system is working properly (i.e., it's just an engine failure), the pilot can autorotate and land on any nearby spot of clear land large enough for the helicopter, and can achieve a safe landing with no or minimal damage. In fact, helicopter pilots frequently practice this maneuver while in flight training.
Airplanes need some kind of runway, by contrast, and this isn't usually available within the glide distance. So they can "land", but it frequently won't be a pretty landing.
The main dangers with helicopter engine failures are 1) it happens too close to the ground, so there's no time to react and enter a safe autorotation, and 2) the pilot is too slow to react (low-inertia rotor systems are more dangerous this way, so helicopters like Robinsons are worse).
Planes and helicopters burn, though.
https://www.smithsonianmag.com/smithsonian-institution/freak...
Here's an attempt to develop a jet fuel that wouldn't burn:
https://www.youtube.com/watch?v=Y33N0raKZBo
Startship will not have an abort capability either.
Neither did the Shuttle, unfortunately.
Unlike the Shuttle there will be a lot more uncrewed testing of Starship, so hopefully it will be more reliable.
planes/helicopters have a fuel source that is orders of magnitude less volatile, and are also able to safely land without power
What fuels do you mean in particular? If you’re talking about hypergolic propellants, those aren’t commonly used as a main propellant on manned rockets. Most planes and helicopters use kerosene, which is also the primary fuel used by the launch stages of manned rockets.
I think rockets in this design space have frequently been closer to prototype quality rather than commercially deployment quality.
Those other systems have other redundancies and safety mechanisms.
1) Commercial planes and helicopters are orders of magnitude safer than space flight. https://usafacts.org/articles/is-flying-safer-than-driving/
2) Both planes and helicopters have an ability to glide (or autogyro) to a relatively safe landing in the event of most failures. A spacecraft can also do that with wings or parachutes, but only if it gets far away from its exploding booster fast enough to survive.
3) Many military planes do have the ability to safely eject passengers.
4) astronauts dying live on stream is a really bad look.
Airline passengers are in the dime-a-dozen category of expendable. Investments in astronauts are significantly higher. You really want them to be re-usable more so than the rockets
You could go without an LES if you can convince NASA that you have sufficient contingencies to not need it (and, of course, you can do almost anything you want on a private flight). SpaceX has been entertaining the idea of not using an escape system on Starship and instead proving its safety through sheer number of flights. Although there also is just a general consensus that the flip maneuver would probably make that necessary even if they had an LES.
From some quick reading it seems like the crewed Dream Chaser is intended to fly without a fairing. The cargo version's ability to fold the wings and fly within a fairing seems to be for 1) compliance with NASAs CRS-2 requirements, 2) wide compatibility with existing boosters that weren't designed for the forces that flying without a fairing would create.
Could be spin from Sierra but that's what they were saying to the press as of 2015 when they announced the cargo variant.
https://spacenews.com/sierra-nevada-hopes-dream-chaser-finds...
The problem with the wings is they generate lift during launch and that will screw up the rocket, thus the fairing. I thought there was no known solution for that.
It seems like you could mitigate that by designing the wing such that when mounted the angle of attack is 0 and thus no lift is generated. Obviously the wing would still have an effect when the booster changes orientation or in cases of high winds. I'm not remotely qualified to calculate the scale of those forces but I don't see why any of that would be a guaranteed showstopper given a booster with enough thrust vectoring capability.
Not any different than shuttle or energia. Lift can be accounted for. It’s not as easy as launching in a fairing, but it’s certainly not impossible.
Fold the wings up?
Seems like Starship fins and Falcon 9 grid fins did that trick as well.
Can't they blow the fairing as part of launch abort?
I'm not a rocket scientist, so I don't really know the answer. But I have some questions:
* How reliable will the "blow the fairing" system be? If it's only used in emergencies (instead of the regular fairing separation mechanism) than it'll suffer from the same problem as emergency generators - they're rarely tested and fail very often when needed.
* How easy is it to get the fairing out of the way once it's opened? Normally, regular aerodynamic forces slough the fairing halves off, but an LES/LAS doesn't have time for that - it's escaping a potentially exploding rocket. And those fairings will act like sails - huge surface area:volume ratio means they're just not going to move fast.
* What happens if DreamChaser hits one of the fairings on the wing? Would it damage it enough that it'd have trouble landing? Is it enough to cause it to foul the escape trajectory? Or even put it in a spin?
It seems like a lot of work to get it to work with or without a fairing.
Soyuz launches with the crew capsule under fairung and even stacked under the orbital module - it still has a LES[0], that pulls off the whole fairing away & then drops the capsule once clear of the rocket.
A bit complicated but was already used in emergency and worked.
[0] https://en.wikipedia.org/wiki/Soyuz_abort_modes#Jettisonable...
That's one more thing to go wrong. In a LES scenario something(s) has gone wrong in an unrecoverable way. Very few systems can be relied upon to exist let alone work correctly. A LES on a crewed capsule is supposed to be able to pull itself from the vehicle all under its own power. It can't assume explosive fasteners on the fairing are functional or actual all function correctly.
You don't want the LES to activate, seem to be working correctly, and then blast the crew into a fairing panel that did not fully separate. The crew doesn't have time to roll down the window and kick it loose.
Star Liner has all the same problems that the Space Shuttle had. In an emergency, how do you get the crew out safely?
Starliner has a launch abort system; the Shuttle did not.
From what I understand, they use a very powerful rocket (much more powerful than Crew Dragon) to get the capsule far away from the booster. I guess it can get far enough away that NASA is satisfied that falling bits of burning SRB aren't a danger to the parachutes.
Didn't the shuttle have this harebrained thing where the crew were supposed to climb all the way to the exit hatch in their pressure suits, extend a boom along the wing in full flight and then parachute out along it?
I thought I read about that. Of course that's effectively no actual escape system lol. They'd be long dead by the time they managed all that in an out of control shuttle.
It was a proposed mechanism that was never taken really seriously.
I guess it depends on what you mean by that. Astronauts were trained on the system and it was aboard the shuttle.
Did the astronauts believe that it's likely that the system would save them? Probably not.
https://www.smithsonianmag.com/air-space-magazine/escape-spe...
Yeah personally I would have taken my chances ditching the craft, tbh. It would probably ditch pretty well considering it doesn't have huge engine pods under the wings.
Yep. That's supposedly for them to ditch in the event that the main engines fail but the shuttle is controllable - they don't have enough energy for a trans-atlantic abort, so they glide and bail out over the ocean.
Harebrained is right.
No idea is a bad idea, but it can be harebrained.
How far did this plan go? Just because it was discussed and documented and thought through does not mean it was something that was actually going to happen. Was this actually developed and the parts&pieces put into place with procedures written up in the flight manual?
Yes.
https://www.smithsonianmag.com/air-space-magazine/escape-spe...
During the Starline abort test only 2 of the 3 parachutes opened, and that was a pad abort test - no SRBs!! NASA not only calling that a "success", but a sufficient success to move onto crewed testing was about the moment I lost all faith in Bridenstine being different. Immediately after leaving office he picked up a cushy consulting type gigs for various aerospace/defense companies (aka Boeing et al). Shocker.
For those who might not know SRB = solid rocket booster. Boeing uses them, SpaceX doesn't. An SRB is basically like a giant firecracker. You light it and it starts burning and doesn't stop until its done. It poses substantial safety concerns in the case of an accident where you need to abort the flight. But they're cheap, extremely powerful, and relatively simple contrasted against liquid fuel engines.
Failure of 1 chute was designed for, though yes, it wasn't a great look.
SRBs are in general very safe, which is why they're still used for human rated rockets.
Well we shall see I suppose. SRB's go back to the Apollo era and NASA safety qualifications often come down to 'are you doing what we've done before'? Hence them refusing to even consider SpaceX retropulsive crew landings, even though that would be a huge step forward.
I would also observe that NASA has a relatively poor safety record contrasted against the Soyuz (which has not lost crew since 1971 in spite of flying more manned missions), and one of the few completely catastrophic crashes we have had, Challenger, was directly related to the SRB. In either case, I expect variance is playing a much larger role than most might appreciate.
While I share your reservations with solid rockets as a main propulsion system on a manned rocket, it turns out they are well suited for launch escape systems themselves for some of the same exact reasons: they’re simple and powerful.
Interestingly, both Crew Dragon and Starliner have eschewed SRB based LES/LAS systems for liquid fueled hypergolic ones. You can tell this because neither capsule has a "puller" on the nose like Apollo/Orion does.
It can’t have “all the same problems” because a number of the engineering problems came from having the spacecraft on the side of the launch vehicle
Pretty sure Star liner is at the top of its stack, so there is no risk of sheets of ice falling on it and damaging it
What? No it doesn't.
Starliner is put on top of the rocket, not next to it.
IIRC one of the big ones is that of how the crew is supposed to board the vehicle. Cargo Dreamchaser is launched in a fairing so that its aerodynamics don't matter on the way up. This is fine because the cargo can be loaded prior to payload integration. But that won't work if they're carrying crew.
Thanks, this is helpful to know. What do you know about the dream chaser problems?
SLS is a jobs program. It's not economically viable at over $1 billion per launch.
As for Blue Origin and New Glenn, this is an object lesson that simply throwing money at the problem doesn't necessarily solve it. Did you know Blue Origin was founded ~18 months before SpaceX?
For the longest time (up until ~9 months ago), Bezos had the former Honeywell CEO in charge of Blue Origin, which to me was such an odd choice. You see, this guy seems to embody everything wrong with corporate America: he was completely focused on not failing rather than succeeding. So there were constant delays with New Glenn and the BE-4 engine, which is years behind schedule. You can't fail if you don't launch.
And the new CEO (David Limp) used to be in charge of Kindles.
Whatever happened to armadillo aerospace?
Excessive hubris around solving hardware problems in software, they blew up their rocket and ran out of money as Carmack couldn’t justify it any longer: https://www.reddit.com/r/space/comments/82qkvl/john_carmack_...
I think it's just more that Carmack didn't want to go all in with his entire life and net worth the way Elon did (and without which SpaceX would certainly have died exactly the same death). And who can blame him?
Musk went all in with Tesla, too. At one point he was down to about $200,000 and was a few hours from bankruptcy of Tesla and himself.
Musk is an enormous risk taker.
It’s easy to take risks if the failure condition is “still a multimillionaire”.
I refuse to think any sufficiently clever billionaire doesn’t have $1-10M in gold buried in a couple geographically distributed places. I know several people with NW of <$50M who have stashed 2-4% of their assets away in this fashion.
World wars happen, governments collapse, favor shifts, etc. Why wouldn’t you have a backup plan when it’s just pennies?
I refuse to believe that he was ever at risk of having less than 5-10M in pocket money left over after everything implodes.
Why bother when you can just have real estate instead?
I'm likely missing something here, but to me this minimises the problem to just a reduction in the number of properties you can move into (assuming some are lost and some of the others sold).
Title to real estate, as well as its ability to be liquidated, rests wholly in the cooperation of the state, as well as their recognition of your legitimate title to same. I’m reminded of the end of Godfather 2.
10-20kg of gold coins buried at gps coordinates in the deep desert has no such limitations.
I think a lot of ultrawealthy who have experience playing the geopolitical game probably must have some hedges like this. Doesn’t Thiel have NZ citizenship without any explicit intention of residing there?
It’s not like value stored like this loses its utility even if the state doesn’t collapse/confiscate your assets/persecute you.
I can’t imagine circumstances where one would end up being a billionaire then ever being a not-millionaire unless you’re thick as a brick.
I’m not a billionaire (technically neither was Elon at the time but that’s besides the point, but I suspect human psychology leads to a non-linear relationship between net work and acceptance of risk. Most billionaires don’t want to become mere millionaires. And people in poverty would likely say it’s easy for someone in the middle class to take risks.
Maybe you don't remember this, but Elon wasn't a Billionaire with his exit from Paypal. He made his bones with Tesla/SpaceX (honestly, mostly Tesla, but we'll see how SpaceX turns out, it could be bigger in the end).
Would you mind providing a source?
"The deal ended up closing on Christmas Eve, hours before Tesla would have gone bankrupt. Musk had just a few hundred thousand dollars left and could not have made payroll the next day."
"Elon Musk" by Ashlee Vance, pg 210
It was a month, not a few hours, and I have no idea where you got the $200,000 number. That is certainly not what Elon himself said. He said 1 month.
https://x.com/elonmusk/status/1323640901248393217
The reason you have no idea is you're talking about different instances of near bankruptcy for Tesla. Which tends to support GP's point.
It's probably no coincidence that Bill Gates was also. Bet the farm 2-3x at least.
Wiki says:
You seem to assume a good CEO equals a successful company, and a good CEO also needs to have industry experience.
I don't know if either of those are actually true, there are plenty of good CEOs who came from zero experience in the industry. And plenty of bad CEOs who came from plenty of experience in the industry. Both of these run successful and not successful companies.
For example the currently Boeing CEO does not have experience in airplanes, came from a business background. And is considered a bad CEO by the average person (though considered a good CEO by stockholders, or at least was before the past few months).
the only assumption i see is the counter to that - a bad CEO equals an unsuccessful company. and i don't think that's a very controversial assumption.
Seems to imply there is an issue with a CEO of a space company previously working on Kindles.
Also seems to imply the CEO is bad because their previously only worked at Honeywell on thermostats.
In my mind none of the above has anything to do with how good or bad a CEO is. Perhaps I am misreading it. In which case ignore me.
All things being equal, you'd want a CEO who understands the business, either by coming up through the ranks or a long career at another company in the same business.
Honeywell is also an aerospace company:
https://aerospace.honeywell.com/
A bad CEO can look great on paper and in the stock price. The product however will likely not keep pace, charging more for a product providing less value.
Long term value, employee satisfaction, and customer satisfaction are all intertwined. New management is more likely than not to harm at least one of those 3 .
I reject the notion that a good manager can manage anything.
I also reject the financialization of modern companies where we put accountants in charge who aren't subject-matter experts whose only playbook is to cut costs and jack up prices.
It's exactly what's wrong with Boeing today.

SLS cost way, way more then $1 billion per launch. More like 4 billion $ per launch. They hope to get it to $2 billion $ eventually but that will take a while. 1 billion $ is the end goal that they use in marketing, but that's not happening anytime this or next decade.
So, the full stack of SLS costs $4.1B. But that includes the cost of Orion which is ~$1.3B when you include the European Service Module, and it includes the cost of 1 year's worth of ground support equipment including upkeep for various buildings like the VAB, etc.
The marginal cost of a cargo SLS (should one ever launch, which is looking increasingly unlikely) is a bit over $2B. Which is still a horrifically high price.
For people who don't know much about SLS, one way to put its cost into context is, every time the full stack with Orion launches, that's about 1/6th of NASA's yearly budget. And that doesn't count any development cost which is several tens of Billions.
I'm not sure that's true. I would bet with Orion its even more. It depends what you consider to be work before launch 1 as launch cost. And we don't really yet know the cost of the EUS.
You can of course get higher if you add development cost as well. But that depends on how many launches there are.
From the OIG report[1]:
We have an idea of an initial cost estimate from this[2].
NASA agreed to buy 2 core stages and 2 EUSes for $3.2B. Since RS-25s are around $100M each and the SRBs are around $200M each, this pushes the cost of the rocket up to $2.4B, maybe a bit more.

It's a total waste of taxpayer money and an extension of the pork of the military/government-aerospace/industrial complex. And they're still using Russian-made rocket engines on Atlas V prior to switching to Vulcan Centaur, another expensive platform. The American taxpayer deserves to have billions in waste cut out and capital used more efficiently at SpaceX and other vendors where there is value/$.
Yet that was historically the most successful approach in XX century for most of research-intensive industries (space, transistors, energy etc) -- when government spends crazy amounts of taxpayers money for some programs that bring little $$ back, but sprawl a lot of commercial startup follow-ups.
Investing in commercial approaches as the step 1 doesn't seem to work in multi-billion R&D endeavors.
So yes, it's not fair, but turns out to be better for the country down the road.
That works for a bit, and then all the others jostle in and start feeding on the pork. SpaceX will get this eventually too if it does well enough and settles into a routine of project bids, project management, technical project success, and more bids.
Cost-plus contracts work during wartime when everybody is motivated by the war to get the job done fast, to end the war and get their friends and family back home safely as soon as possible.
During peace time, the predominant motive is to maximize profit by dragging out the work.
True about founding before SpaceX. But wasn't it just a think tank for a while?
How does that make it better? :p
In many ways it still is just a think tank.
There's a phrase "failure to launch" that would imply the opposite sentiment
I believe that the parent commenter means "you can't fail if you don't try"
If you're too risk adverse to even try, then just sit down and get out of the way. I want to put the shut up part of that quote in there too as in quit fighting for contracts/bids that could go to people that aren't afraid.
You can't fail if you don't try, but you can't succeed either.
It's also a hedge against SpaceX imploding/compromise/whatever. In that role, cost is less important than having a provably functional product. I'm not saying anything is likely to happen to SpaceX, just saying that having SpaceX as a SPOF in the US space program would not be the best strategy.
Starliner is that hedge, SLS isn't. Using SLS for delivery to the ISS would be a crime against tax payers.
Such a sad take though, SpaceX is probably filled with America loving people not matter what a PR firms bot spew online about musk
The BE-4 was launched earlier this year. I wouldn’t assume that late means never.
the BE-4 is an engine - it was finally used in a rocket january yes - after being in development for almost 15 years. That us still kinda slow compared to spacex.
New Glenn was announced in 2016. An 8 year long development process is hardly slow in aerospace. The development costs are also somewhere between three and four billion dollars. The real problem with Blue Origin is that Jeff didn't really give a damn about Blue Origin and let himself get scammed out of his money.
Given how many people work at Blue, I would suggest its more then four billion $. The Ariane 6 cost 5 billion $ or more. BlueOrigin has been spending almost 2 billion $ a year.
Any sufficiently large acquisition is indistinguishable from a jobs program.
Oooh the founding before spacex is a huge surprise. I always assumed it was bezos trying to keep up with the joneses with musk.
Only possible with the existence of "billionaires".
If by that you mean "average people pooling their billions to further advance science and technology", sure.
None of this was done in a vacuum of billionaire self funding.
Is that true? We live in a remarkably gilded age where a handful of people (whose names we all know) cashed in on the Dot-Com Boom. Their pleasure appears to be, for a few of them anyway, rockets and spacecraft.
A vacuum of billionaire self funding? Of course not, but would these ventures have progressed to where they are without the deep pockets of some of these billionaires?
IIRC, Musk wasn't listed as a billionaire until 2012, and that possibly as a result of (rather than cause of) SpaceX having successfully sent cargo to the ISS.
People mock him for being bad at estimating how long projects will take… but even if you agree with the critics, he's still the one-eyed in the land of the blind when it comes to space mission project planning.
He did self-fund SpaceX to the tune of $100M or so. He wasn’t a billionaire, but that was awful close.
That's a factor of ten, which is like calling me a millionaire when I saved just enough to buy a 35 square meter apartment in a small village just outside Cambridge (UK)… in the middle of the house price dip from the global financial crisis.
He also put money into Tesla and Solar City at the time. We don’t know the true extent of his wealth (Forbes estimates are notoriously inaccurate).
Fair, I've heard the same from chatting with someone who shall not be named who got on a different list.
I can't remember if it was them or someone else who said that people lie about their wealth all the time for lists like these; the show-offs who want on them and pretend to have more, and the quiet ones who want off them and pretend to have less. (The person previously mentioned was one of the quiet ones).
The funding was from nasa contracts, which is public funds. Someone would have done it even as a consortium of sub billionaires.
Is neutron to be man rated?
Yes and no.
It's probably more accurate to say "human ratable". They're planning on designing the rocket with human rating in mind, so that if they want to do it in the future, it'll be easier.
But NASA doesn't human rate a rocket - they human rate the entire system as a whole, so it doesn't really make sense to say "human rate Neutron".
I wonder how that's supposed to work with their unique captive fairing design. Feels like they'd have to design crew flight specific boosters which don't have the fairings.
Rocket Lab mentions “human spaceflight” on the Neutron page, that’s the only mention I’ve seen of it. I haven’t seen any plans for a spacecraft for carrying humans or how they might handle re-entry.
https://www.rocketlabusa.com/launch/neutron/
It's the new billionaire yacht club.
I doubt there are any billionaires in Boeing, or NASA.
For purposes of discussion, ignoring Boeing is something I think is acceptable at this point. They comment was clearly a nod to Bezos/Musk. Sadly, as far behind as Blue Origin is to SpaceX, I still the less poorly of them than Boeing even after today's launch
They comment on a thread about Boeing’s Starliner ferrying NASA astronauts to the ISS atop a ULA rocket.
Don't forget that for the foreseeable future, until other plans are made, there is a hard mission count limit for starliner, which is the number of remaining atlas V cores. The engines are Russian made and subject to sanction, so nasa could just refuse to recertify starliner on a new platform, so sad, so sorry, and have starliner just disappeae into tte night while saving face fir boeing.
NASA is keener on having Starliner flying than Boeing is. More likely scenario is Boeing decide they don't want to fly it anymore and they don't bother proceeding with the recertification, at least not without getting a lot more money from NASA.
. . . so nasa could just refuse to recertify starliner on a new platform . . .
That could happen, but I don't see it as likely. NASA is far more likely to spend ridiculous amounts of money to keep it alive in the name of "competition" or some such.
SLS + Orion is so expensive that it's not worth listing, IMO.
Also doesn’t meet the same flight certification standards as the other options listed.
While EU has none.
EU cannibalized its one (1) existing production line for making spacecraft (used to be busy making ATVs for ISS resupply) for Orion's service module production. They're not interested at all in increasing their own capabilities, they just want to not completely lose it.
For me the crazy part is that SpaceX has done 12 crewed flights before Boeing even got their first set of test pilots of the ground. I recall back when NASA was justifying giving nearly twice as much money to Boeing that "because they were much more likely to be ready sooner."
It's not surprising that people in the largest organization on earth (our federal government) think that way. They are so risk averse it creates its own risk, namely, what if you miss out on one great opportunity after another due to risk aversion.
It's a really exciting time. Also the Chinese have lots of space going on. Chang'e 5 is on its way back from the moon. Tiangong is quite large now. I'm thrilled to see humanity accelerate this.
I don't think it's crazy; it's competition, which is what should be happening. We want multiple private companies to be in this game, because that's the only way access to space will ever become practical at any kind of scale.
Went from 0 to many pretty fast really.
I wonder when we will first step foot on the moon?
SLS + Orion should be in that second category.
