>1969 : Humanity conquers the Moon in less than 3 years
>2019 : Nothing happens

Space exploration is the biggest failure in Human History. The only field where we don't make any progress. Fascinating.

>>10443276
You know that it is caused by waste of resources in other useless things, right?
In 1969 space exploration was like one of the most important things for USA

>>10443276
To be fair Apollo (and the Space Race as a whole) was abit of a freak event in manned spaceflight history and it set a high standard for manned mission that didn't get meet for sometime.

If the Space Race never happened, then maybe we would see a more gradual build up in manned spaceflight rather than the massive jump and pause we have now.

The welding continues...

If there's something strange in your launch site, who you gonna call?...

>>10443283
>>10443282
>>10443276
I think you guys are underestimating what our manned programs have been doing since Apollo. Sure, we could devote tons of effort to landing on the moon again, but without serious long term goals this is pointless. NASA has been for decades gathering data on how living in space affects humans and developing technology to make long term space habitation possible.

We now have people staying regularly in space for months, and some have stayed for a year. This is a far cry from the short excursions during the Apollo era, and this seemingly 'boring' period since then is going to be considered important for getting us ready for more permanent endeavors on the moon, Mars, and other deep space projects.

>>10443351
Not to mention all the unmanned projects that gather invaluable scientific data that will help us to prepare for future human exploration of the solar system.

>>10443317
I first read that as Laundry. I suppose if something goes wrong with launch you could in fact have a laundry emergency.

>>10443351
>>10443354
I agree with you. Spaceflight since Apollo hasn't been "boring". Less ambitious? Maybe, but is not like NASA has been doing nothing for decades.

In my original post >>10443283 I was talking about "slow" from the perspective of the public who might not know much about what NASA is doing.

>>10443357
"Brown Alert" exists for a reason.

We are yet to build a high earth orbit station let alone even consider beginning to study the effects of partial gravity on the human body which we may safely do only using large rotating space stations.

It will inevitably take centuries if not more for people to reach Mars and even the Moon simply because repeating some short Apollo surface visit is pointless, wasteful, and dangerous.

Slow and steady while building up knowledge and technology is the only way to do things right. If we just push it or endlessly change directions nothing will ever happen.

This is why I see great potential in the proposed Lunar Orbital Platform-Gateway as a step in the right direction.

>>10443377
I agree with you. I'm personally a big fan of setting up a semi permanent base on one of Mars' moons before a manned mission to the surface of Mars.

>>10443360
'Less ambitious' is probably accurate. After Apollo, the people at NASA slowly realized that space was much more challenging than previously thought as far as long term habitation or colonization is concerned. This was just after the first probes confirmed that Venus and Mars are uninhabitable. So, the science fiction dreams of the 60's came to an end and they started focusing on realistic long term objectives.

It's also not that colonizing space is impossible, just that it has taken us half a century to get to a point were we can realistically talk about doing it sometime soon. The reason we are to the point where we are (maybe) almost ready to do long distance deep space missions is because of decades of research and experience.

Also, we will very likely see some short, Apollo-style moon landings in the next few decades. The difference now is that they will only be demonstrations of technology before long term objectives are carried out. (constructing a semi-permanent lunar base etc.)

The first trips to Mars will likely not be to build permanent colonies, but to do some science and gain the experience necessary to make our presence on Mars more permanent over the course of many decades. However, the long distance and timescales involved with Mars missions makes them completely different than the moon landings even if they are similarly nearsighted at first.

>>10443080
im already on nuclear fission and fusion ship designs. i do it just for kicks. having a engine/reactor that runs for 900 million years without having re-fuel is nice.

>>10443418
Great overview! I agree with what you have said. Future manned spaceflight will and should be careful steps. While some people want "Apollo on Mars", the planet itself isn't suited for a mission like that.

However, the slow and careful approach has one huge Achilles heel. Lack of public interest. When I said Apollo set a high standard, I meant that the public expects high speed progress and ambitious missions like Apollo because of it. Any mission that is going to take more than 8 years is just simply too boring for them. That's why missions that skip the Moon and go straight to Mars are pushed, they're more interesting. An example of this is Elon Musk and SpaceX. They were promoting a fast trip to Mars and the public loved it, but when they started to shift towards going to the Moon first then accusations started being thrown that SpaceX is abandoning their original goals.

I think future manned missions need to balance what's practical and what will inspire the public. Much like how a camera was added to the originally entirety scientific Juno probe to take beautiful pictures for the public. How do that without risking lives? I'm not sure.

A platform is being built on the rollers...

when is this hippedyhoppedy thingy supposed to fly again?

>>10443377
If the BFR does what they claim it will do then putting up a rotating space station would already be a step closer.
Hell, the small module+tether solution for a spinning station can already be done today.
And at some point there where plans for adding a spinning wheel to the ISS, but they didnt do it because they could never get the station stabel enough when it actually would start spinning.

>>10443482
>when is this hippedyhoppedy thingy supposed to explode again?
Fixed that for you.

>>10443482
Originally March, but likely later now. The main constraint being the Raptor testing regime, with the hopper base seemingly complete, nosecone being welded together and transporter currently being assembled.

>>10443494

Neat, going to save that link.

>>10443507
Could make a drinking game out of the launch-thread as well

Do a shot for each time someone either calls someone a shill or actually is a shill
Do two shots for each time someone mentions "hullo there"
Five shots if it explodes
10 shots if it actually works

you get the deal, we'll all be dead from alcohol poisoning before T-00

Looks like a segment of the nosecone is getting lifted.

Why does nobody want to go see this?

>>10443610
You shouldn't need a CDL if it never goes on public streets. But I'll bet it wasn't cheap and they (or their insurance company) didn't want anybody driving it who wasn't certified.

The fuck?
Is this version going to be taller than the previous?

>>10443761
That's a lot of rings. Either they're going to make a full-size hopper (now that they have the time), or they're going to make two for twice the price.

>>10443794
whats going on here

>>10443797
they're building a platform to rest the hopper on top of the roll-lift to give the roll-lift enough height to pick it up and stabilize it
those roll-lifts can jack up pretty high

>>10443797
>>10443808
Basically, their building a crawler/hydraulic jack hybrid for transporting the hopper and installing Raptors.

they're the same blue things seen in this image:>>10443794

now that I look at it again, this one's much smaller than the one I fucked with

Hopefully they will remember to strap it down properly this time when they fit the new nose piece.

When will we terraform this bad boy?

>>10443909

>>10443354

the goal is to have as many humans on planteray body as possible to establish a micro colony. People say what is there on the moon or mars. The point is it doesnt matter.
Why did europeans goto america to colonize it when everything that was in america was already in europe.
HUMANS in enough quantity will become the economic justification

>>10443351
>NASA has been for decades gathering data on how living in space affects humans

Yeah except the most important fucking one, being sub 1g living. A small centrifuge unit with rats or mice or whatever that spins a few cages at different gees should have been done fucking decades ago, instead they are sending up like number 13 "rats in 0g" experiment, woop dee fuck. We can't make any fucking plans for colonisation of other bodies because we don't even know if we can live on them long term.

It's a fucking joke.

>>10443929
The thing that was in America that wasn't in Europe was free land and no government busybodies sticking their nose into your business and charging your rent for every fucking thing. Mars also has this advantage.

>>10443351
>>10443354
I like this 90s hard sci-fi space aesthetic where you have big spaceships cobbled together from bits and pieces each small enough to fit into a space shuttle. This will turn out to be incredibly quaint when we actually get around to building massive ships. Once you build in orbit there's no need for all those spindly components.

>>10443961
I think the moon and mars are going to get a bit of regulatory bullshit going on from Earth based governments, that being said they are just the proving grounds, once the technology is established I think the asteroid belt is going to be the real wild west, especially as a lot of rocks don't need anywhere near the amount of dv to reach that Mars does

>>10443909
as i understand it, the best way to colonize venus would either be to create giant floating cloud cities ORRR put giant solar shades at the lagrange point to cool the planet down, i think the latter solution is more cost effective

>I think the moon and mars are going to get a bit of regulatory bullshit going on from Earth based governments

the moon is too close to earth, but i could easily see mars gain independence, just the 8 to 14 minute telecom gab will spawn a new culture, Not to mention the distance for item to arrive and the bureaucratic chicanery of earth officials will make Martians tell earth to go fuck themselves.

Also Mars will be at a military advantage to earth, its capable of heaviy lifting vehicles into orbit as well as contruction of a space elevator using existing technology. means they can have fleets of space craft to protect their borders. Also think about the fact that you will be having population of super high IQ people breeding with each other working to the most harsh environment, just the evolutionary pressures of survival will make martians more intelligent

>>10444051
If you are having to build fuck huge centrifuge bowls then you have removed pretty much the only advantage Mars has over asteroid habitats. In fact spinning habitats will be much much easier in space.

>>10443080
So is this thing meant to test the raptors? Or they will start with the merlins, btw, does it have engines already?

>>10444133
There is no advantage planets have that space habitats doesn't beat
colonizing planets is the meme

>>10444178
If low g works out, not having to build huge rotating bullshit is a massive advantage. That's pretty much the only one, but is very significant for early colonies where you need to build living space as fast as possible

>>10444178
A planet colony can more easily expand it's area compared to a space colony. It'll be easier to travel between colonies on the same planet compared to space colonies that may be several light minutes apart. A planet colony can farm crops in the open or in greenhouses allowing higher food production compared to a space colony which may be more limited in useable area.

Did they lift the piece or no?

Moving closer and closer towards a Starlink launch timeline. They've just recently filed a FCC license with launch trajectory possibly matching those needed for Starlink constellation.

Launch time possibly ~May or later.

>>10444133
Mars has all the material and structure already there... find a crater and build rail around it

>>10444207
Elon wants the initial Starlink up no later than June. So May or June is the proper timeline, however there could be few months delays. Hopefully not. I want to switch from Comcast soon. I'll pay ~$40-60/m for 100Mbps to 1Gbps.

>>10443929
>humans in enough quantity will become the economic justification

As dumb as your analogy is, I agree with you. The only way to really colonize space is to have a society and economy there. This will probably happen quite slowly as astronauts who work in space for long periods of time bring their families to settle near them.

>>10444453
Yeah it's a big crumple zone so instead of a nominal landing being effectively a car crash like with soyuz the capsule can actually touch down softly.

>>10444952
ALON shouldn't surprise anyone, when corundum (aluminum oxide) is transparent already. Adding nitrogen and sintering it so that it's amorphous rather than crystalline just makes it tougher.

>>10445009
It was only a guess man. Alon would be amazing though

This is what Muskrats unironically believe

Mars makes the Sahara desert look like Garden Eden. That place will struggle for survival to all eternity, if it ever gets independent, and will probably lose that fight pretty quickly. The idea of a mars nation building up a space fleet is so ridicuolous lol

>>10445775
First, the anon didn't make any reference to SpaceX. Plus the idea of an independent Mars has been around long before Elon got famous.

Second, being months or years away from Earth will definitely make the Martian colony develop its own identity away from Earth. Just look at New World colonial history for real life examples.

Third, Mars' lower gravity and thinner atmosphere facilitates easier heavy lifting from surface to orbit compared to Earth. So it's not unreasonable to envision that an independent Mars could buld a space presence faster than Earth.

The colony could grow and gain higher GDP. Also history has shown that self sustaining colonies far away from their motherland are difficult to control even to the most powerful empires.

It will take ages to make life on mars sustainable, as anon said, it is like building a functional society on the sahara but with barely any atmosphere and lethal radiation.
The purely exploration phase relying on earth for pretty much anything will be everything our generation will see.

>>10445820
No, because Mars is extremely poor in ressources and just keeping people alive will be so expensive that the peope there will live the equivalent life of negroes in mud huts. Building up a space fleet is competely out of the question, all ressources will go towards survival.

>>10445821

Speaking of which...I get needing water, but where are they getting the carbon or nitrogen from? Does the Moon have significant deposits of it them that I'm unaware of?

>>10445823
things that Mars has that the Sahara doesn't:
>cheap and plentiful iron
>a thin layer of dust instead of great heaping mounds of it
>insights into the formation of the solar system and the history of Earth

>>10445829
you don't need nitrogen
the big thing is not needing to bring oxygen in, although if all you need is oxygen you can extract that from the soil
there are orbital sources of carbon in near earth asteroids maybe, but that's a bit of a stretch
it's a bit of a bitch, but NTR with hydrogen could work, or straight water if you wanted to be quick and dirty

>>10445823
>The purely exploration phase relying on earth for pretty much anything will be everything our generation will see.
I agree with you. The ideas of an independent Mars will only be possible in the far future. Far beyond what you and I would see unless immortality was invented. I was talking speculatively about the possibilities in the far future.

I think the possibility of a near-independent Mars is possible near-term even on those basic science expeditions, because they will need to make their own food and other essential supplies
supplies from earth will be extremely limited to only the most crucial of supplies unable to be supplied on Mars

>>10445858
Luna will be space antarctica
>>10445863
literally all you need to do to extract iron from iron oxide is heat that bitch with a big magnifying glass and a furnace
easy as shit nigga, that's step 1 or 2 of extracting titanium from lunar basalt as well (extract the iron first)
it doesn't matter if it's "enough" it needs to be done, and the "permanent" part is a very simple extension of that mission (because it is, by necessity, all ready very long duration)

>>10445829
Carbon and oxygen you get from atmospheric CO2.
It's hydrogen that gets a bit tricky, but that's in water, along with some bonus oxygen.
Nitrogen is nice for a breathable atmosphere, but there should be other options.

>>10445872
>Carbon and oxygen you get from atmospheric CO2.
I'm talking about the Moon, not Mars.

>>10445870
To add to this. If the moons of Mars were settled before manned missions to the surface, then the Martian colony will have easy access to established industry without having to start completely from scratch.

>>10445872
Mars has easy carbon from atmospheric CO2, but Luna is trickier
shipping it from earth or NEO capture?
>>10445876
easier to start from the surface of Mars than the moons, I think
aerocapture >> propulsive capture

>>10445855
You are just completely fucking deluded mate. Just to gather the ressources and manufacture solar panels so their life support don't die will be so difficult that it might never happen.

>easier to start from the surface of Mars than the moons, I think
>aerocapture >> propulsive capture
Aerocapture can still be used for Martin moon missions coming from interplanetary space. Plus any modules sent to the moons need to only be proofed for space rather than surface bound modules which need to be proofed for space, reentry, and Martian surface conditions.

There may be other volatiles frozen on lunar poles along with water ice. Methane or ammonia ices are a possibility. But nobody knows for sure. The fact that NASA still has not sent a lander to explore lunar pole is a travesty.

>>10446025
I prefer the idea of a big dumb rocket that can lift hundreds of tons into orbit in one go than the reusable, sub 100 ton rockets we have now, imagine how much cheaper space launches would become, and thus how much more stuff we can throw up there without having to worry about cost/weight restrictions

>>10445509
plutonium-239 has a half life of 24,000 years. there are a bunch of isotopes. some only last days and other last for hundreds/thousands of years. getting it legally is a bitch.

>>10445790
Mars has all the resources required for a flourishing civilization. An entire planet worth of resources.

It will certainly be hard to establish a colony, but I remain optimistic. Why? Because there will be one resource, a very important one, where Mars will be superior to Earth. And that resource is people. Mars will be settled by the very elite of humanity, a 130+ IQ average, and due to founder effect, Martian population will make even most developed countries on Earth look like a bunch of niggers on average.

>>10443080
for god sakes just use a fission plant with a bunch of ionic thrusters on it for you damn ship. this is silly as fuck. they have had nuclear powered ram jets since the 40's.

if your fuel has a half life so long that your reactor runs that long, then your fuel is shit as fuel.

>>10446082
no they had like one test nuclear ramjet that they scrapped because it leaked radiation everywhere it went

That depends on the volcanic activity. If the surface is still too active, it makes more sense to just wait until we can dismantle the planet even if that takes a few hundred to thousands of years.

Blame the US government's limp wristed way of budgeting NASA. If it's not super important to the government right now then it won't get much money.

>>10446059
Big dumb rockets are great. No need to push the limits of engineering, everything needed is already there. All we need are semi-regular super large payloads to justify their existence.

>>10446200

Fixed that, right now their space program is filled with delays, never happenings, outdated tech and underfunded projects.

>>10446295
Tbh the NK33 using ablative cooling and the N1 using 30 of them would cause massive problems for any rocket program.

Hopper hat has been moved to the concrete jig.

>>10446260
China hasn't totally surpassed them yet: Russian engines are still far superior with the YF-100 being China's only decent engine but it still pales in comparison to the RD-170 family, their human spaceflight capabilities are similar with the Shenzhou being a reverse engineered Soyuz (although Russia have far more launch experience) and China planning to launch a Mir-class space station soon; also China have yet to launch a successful interplanetary probe unlike the Russians who's Venus and Phobos probes were great. The one metric in which China surpasses Russia is launch vehicles, with the LM-5 surpassing Russia's most powerful operational rocket: the Proton's lifting power.

>>10445790
Let's be clear though: there's not going to be much in the way of gibs on Mars to drag everyone down

jello baby meme is unfounded, no research exists on development and function of humans in medium gravity environments

>>10446295
>it almost worked
No it isn't. It's best service record is explosion 100 seconds into flight.
In, fact, it probably would work, because despite what people say engines wasn't the issue. Engines was literaly best part of it.
The issue was that it was developed extremely rushed and not really tested.

>>10446348
they tested it four times and worked out kinks each time

>>10446347

a third of earth gravity is not medium.

10446373
>demographics and intelligence averages isn't real because ad hom
No (You) for you

>>10446316
The LM-5 has had something of a tortured development process so far. Minor anomalies on stage one in flight one and then an engine failure on stage one in flight two that led to the complete loss of the payload. The delays since flight two look like they will continue to be extended all the way to two years after the incident.

>>10446371
This the cringiest thing ITT.

Also oh yeah Mars great entrepreneur paradise. I wonder though what Elon will do when there is no government he can leech money off.

>>10446354
The point is that if safe reproduction is possible, the entire starter batch of humans on mars are going to be at least 20 IQ points above the human average. Since intelligence is partly genetic, the normal distribution of a population descended mostly from that group is going to be shifted up the scale a little.

>>10446371
We'll have gene editing soon, because it only takes one advanced country to start before everyone else will be forced to join in. My worry is wtf happens in a world entirely populated by geniuses. No doubt there's a famous scifi book about this..

>>10446348
>>In, fact, it probably would work, because despite what people say engines wasn't the issue. Engines was literaly best part of it.

Antares begs to differ.

>>10446357
First time Mars missions are very unlikely to be successful, unless your name is India. Also, that was a small and simple orbiter not a lander.

>>10446387
Engine troubles seem to be the Chinese space program's biggest shortcoming at the moment, I've heard that LM-9's development is also being effected problems with the YF-500.

>>10446452
makes sense, engines are the hardest part of rockets

>>10446452
>>10446459
They have engine development problems in general, both for jet aircraft and rockets. Most of their 'stealth' aircraft (both their domestic design and the F-35 air frame copy) haven't seen much use because they haven't been able to make engines to the spec the projects require yet, they have really anemic performance.

>>10446418
Little would change
Intelligence =! Drive and motivation
If the genius is a lazy bastard that just wants an easy job on a drill press, that's one less competing for something better
Plus, we got automation coming, so they can fill the increased number of non-automatable jobs with their increased ability

>>10446464
I'm willing to bet it all stems from their shit metallurgy, the west has basically been unable to outsource high quality metallurgy out to the Chinese, although not for lack of trying.

>>10446459
>makes sense, engines are the hardest part of rockets
I'm an aerospace engineer and I can confirm. Regen cooling and propellant injectors are the biggest headaches I've run into so far.

>>10446474
There's a lot of talk about Russia selling RD-180s to China, because Russia are desperate for cash and China seemingly can't build high performance rocket engines. Russia already helped build the YF-100 with technology transfer but the components were 100% indigenous. I'm interested if China will be able to reverse engineer the RD-180 with their shitty metallurgy, if they get their hands on it.

>>10446489
now imagine you can't trust your suppliers to give you good quality metal (or even what you asked for)

>>10446500
That would make me give up engineering and become a researcher.

To share a somewhat amusing story about regen cooling. We had a guy who knows alot about heat transfer write a matlab code to determine the size of the cooling passages. When I asked him about the principles of the code and how it works, he sent me this.

Uh huh, and it outputs almost zero power due to that extremely slow decay rate. That's why it's only used to generate power via a sustained fission reaction, which uses it up hundreds of millions of times faster than natural decay processes.

Absolutely! That's why I use factors of 8 on anything I'm not sure about (which is alot right now).

>>10446177
I think the suggestion to cool venus down is because the whole planet is too close to some sort of thermodynamic equilibrium, which is one of the possible explanations as to why there is no dynamo effect (no convection within the planet). That's just one of the potential explanations as to why venus doesn't have a magnetic field.
The other reason you'd wanna cool down venus (by a lot) is to freeze all that carbon dioxide to reduce surface pressure which is also relevant to >>10446200
cool enough and it'll start raining CO2
even cooler and it'll start snowing CO2
Eventually the pressure will drop to a point where liquid CO2 can't exist and it'll just snow CO2, which will facilitate the drop in pressure
Then I dunno. harvest it all and make a shitton of pop or use it in the sabatier process with imported hydrogen, or export the CO2 to the hydrogen.
Or crack the CO2 for oxygen and carbon. then use the carbon for carbon nanotubes

I know nothing about astrophysics and little of engineering, but how hard can this be? Just have water storage, which is needed anyway, along the outer edge as ballast and pump it where needed to stabilize the station?
