>>7495757
When the price is down to 250,000 SpaceX credits, everyone will want to go live on Mars. It's the future of humanity.

>>7495762
I wouldn't, because it sounds fucking retarded.

>>7495764
Fine, Elon and I will just leave you to rot on the earth once nuclear winter sits in or an asteroid ruins Earth. Mars is the future of humanity, you ULA shill.

All of your skeptisicims are already covered in the WaitButWhy article. Elon knows the risk, it's a very very in depth explanation about all of those aspects. Check it out.

Here's how SpaceX is getting to Mars. Just read the article.

What is he, your waifu?

>>7495820
No, but he cares a lot about getting humanity to Mars.

Why do I love ULA so much? It's pretty simple when I think about it. ULA isn't just the best launch provider in the country; they might just be the greatest launch provider of all time. Just imaging the Altas V riding through the skies of Earth, the wind on its fairing, the mighty RD-180 below it. As she rides through the red sky, NASA swoons at her very scent. They know how she smells; the essence of burning RP-1 smell is sold in Orlando under the name of "Space Orgasm." The very nature of ULA is mystery. Could they be playing a deeper game than even Tory Bruno realizes? The answer is yes, ULA has transcended such boundaries as the physical world, and has free will to do whatever they sees fit. However, ULA is filled with such guile, such arcane craft that they does not even use these powers. Why, you might ask? You will never know, for the mind of the ULA is not one that is easily penetrated. ULA rockets are such a force of nature in this realm that nothing can truly touch them, the only thing keeping them bound to this world at all is their will to exist within the preordained boundaries understood physics. ULA is not only beyond the comprehension of us, it exists within a plane of true focus and beauty. Observe the plume of exhaust gasses from this Delta IV, the gorgeous and rippling flames, the gallant fairing, and most importantly, its engines. Her engines, like cauldrons straight from hell, provide the only glimpse into the true machinations of ULA. Do not stare into them. Many good men have gone mad in the attempt. ULA is not just a launch provider, a formless collection of engineers and rockets; they are themselves the binding that holds the word together. Without ULA, Musk the Menace takes over and the entire space industry as we know it crumbles. The Mississippi would stop flowing without ULA, Kessler syndrome would take over in orbit, and the space station would fall without their fiery gaze. These are just of a few of the reasons why I like ULA so much.

>>7495833
ULA won't be doing this, they're just greedy crooks who don't care about humanity.

>>7495839
Terraforming Mars and making it similar to Earth is impossible.

>>7495839
Go to bed, Elon.

>>7495840
Why?

>>7495666
Musk said he doesn't think the colony will reach a million until 2070

>>7495840

>>7495841

>>7495841
why is this so pleasing to watch ?

>>7495862
Because you are a bitter resenting asshole who likes to see others fail so you can justify your own worthlessness.

>>7495666
Is it even legal to send people away to live in tin cans till they die? It sounds like it's something you're not allowed to do to people. Any children born on Mars will be forced to spend their time in tin cans and tubes. It's immoral

HOW does he do it?

>>7495872
>Any children born in ~insert third world shithole country here~ will be forced to spend their time malnourished living in squalor and famine. It's immoral

Mars is FAR less stable than Earth as far as supporting life goes.

Even in the middle of a nuclear war on Earth, chances of survival will be greater on Earth than on Mars. Life expectancy on Earth will be longer than life expectancy on Mars.

I will be more likely to survive longer on Earth than on Mars.

Also, if a devastating nuclear war erupts on Earth, destroying all technological infrastructure and killing off 50%+ of the population, then all the people on Mars will eventually die from lack of resources because no more resupply coming from Earth.

Which means the only people left living in the long term will be those holed up on Earth eating roaches and drinking water from underground springs.

Even if a giant asteroid hits Earth, life will still probably survive longer on Earth than on Mars.

>>7496019
It's unmanned and decommissioned

>>7496015
Learning about what SpaceX is doing and why they’re doing it can take you from a place where thinking the prospect of humans moving to Mars is totally ludicrous to a place where you accept the logic that it’s actually an important thing to do and something that’s possible and even likely to happen. But that’s different than really believing it’ll happen.

>>7496034
As you read this post, even if you agree with what you’re reading, if you had to quickly bet $1,000 on whether people will be moving to Mars in 20 years, there’s a good chance you’d bet against it, because deep down, your brain hasn’t really accepted it. And that’s fair—your brain bases things on experience, and experience tells it that moving to Mars is not something that people ever do.

>>7496038
But I’m pretty sure your brain’s in for some big surprises over the next few decades, for a bunch of reasons, and if you’re willing to accept that possibility, try to absorb the fact that a section titled “Phase 3: Colonize Mars” might actually—really—be based in reality.

Everything from here on is based on the guesswork of Musk and others in the field. Here’s those people’s best crack at predicting how this will all play out:

Then something big will happen. Someone—probably SpaceX, probably in about ten years—will send the first crew of people to Mars. For anyone under the age of 50 who’s annoyed they weren’t alive and sentient in 1969 to get caught up in the excitement of the moon landing—you’re finally going to have your day. Somewhere out there, right now on this Earth, is the Neil Armstrong of Mars. No one knows who they are—they might not even know who they are—but everyone on Earth will know their name soon.

>>7496032
just like you're mom in bed last night tbh fam

>>7496043
So with the price of a ticket plummeting downwards and the first crewed Mars mission having opened the floodgates, we’ll be ready to start colonizing. The big question will be, “Who wants to be the first to pay hundreds of thousands of dollars to go on a possibly-very-dangerous three-month trip to a much colder Antarctica where you can’t breathe the air or let the sun touch your face??”

By the time the planets are in place, there will be a group of MCT spacecraft—what Musk calls the “colonial fleet”—orbiting the Earth, fueled up and ready to go, and at just the right moment, the fleet will take off for Mars.

Three-to-six months later, the spacecraft will get to Mars, descend through the atmosphere, and land propulsively. The people will get out, probably to a fun welcome celebration put on by the existing residents, and unload everything over the next few weeks.

About two years later, when the planets are again aligned, right around the time Earth is launching the next colonial fleet, the group of spacecraft that came to Mars two years earlier will head back to Earth, carrying anyone on Mars who’s over it.

Three-to-six months later, the spacecraft will arrive back on Earth, land propulsively, and head in for maintenance so they’ll be ready to head back to Mars in two more years.

>>7496048
And then, something will start to happen.

The hardest part will be over, and more people will want to go.

The first return ships will come back with people, and it’ll remind everyone on Earth that it doesn’t have to be a one-way ticket—and more people will want to go.

The people who come back to Earth will be commended for their courage, some of the people on Mars will write best-selling books about their experience, and others will film a little TV show about the early settlement and become household names on Earth—and more people will want to go.

People on Earth will see gorgeous photos of Martians hiking around on Olympus Mons and in Valles Marinaris, a mountain and canyon far bigger than any on Earth—and more people will want to go.

People will hear about being able to jump off a 20-foot cliff without hurting yourself and watch viral YouTube clips of new kinds of extreme sports that can only be played with Mars’ 38% gravity situation—and more people will want to go.

Can anyone explain the advantages of this toxic fuel Proton is designed to use?

Also, today's launch. Very sexy for a heavy rocket.

https://www.youtube.com/watch?v=ikWxUn5upPg

>>7496347
>Can anyone explain the advantages of this toxic fuel Proton is designed to use?
Okay, Proton uses NTO/UDMH. Both NTO and UDMH are liquid at room temperature, so no insulation, low-temperature brittleness or cryogenic fluids boiling off, and they're hypergolic, which means that they ignite instantly on contact with each other, which makes the engines simpler, since no ignition system is needed and combustion stability is less of a concern.

NTO, "nitrogen tetroxide" (technically dinitrogen tetroxide), is very cheap and, while it's very toxic (catch a lungful of the fumes off of this, and you'll probably drop dead tomorrow), it doesn't survive long in the environment. It exists in equilibrium with nitrogen dioxide, a red gas. It's produced by reacting nitric oxide with oxygen, after nitric oxide is produced by catalytic oxidation of ammonia. Normally, nitrogen dioxide is made as a step in the production of nitric acid, which is produced when it simply contacts water. This is why NTO isn't a long-term pollutant.

UDMH is a nastier long-term pollutant, and more expensive. It is "unsymmetrical dimethyl hydrazine". I'm not sure how they make it, but it's hydrazine with two methyl groups stuck on one end in place of the hydrogen atoms. The methyl groups make it more stable than hydrazine, somehow. Using just one methyl group also works (giving MMH - monomethyl hydrazine), but for some reason, this is more expensive to produce. It doesn't quite give as good performance as pure hydrazine, but UDMH's superior stability means that it's practical to use it in a regeneratively cooled engine. In other words, you can get it hotter than hydrazine without it blowing up. But the stability also makes it last much longer in the environment, which is bad if you spill it.

I'm a little surprised that NTO/kerosene hasn't been done for a big rocket, since kerosene is cheaper and less toxic. However, this wouldn't be hypergolic, and the performance would be poorer.

>>7496384
Oh, and NTO is pretty much non-corrosive, as long as you keep it dry (if you let moisture get at it, it forms nitric acid). Nitric acid is also used for rocket oxidizer (usually as red fuming nitric acid), but it is very corrosive, so careful attention needs to be paid to material compatibility.

UDMH and NTO both have some material compatibility issues, but they're pretty easy to manage. Nitric acid is a pain in the ass, because you could hardly put glass tanks on a rocket.

You do have to pay some attention to temperature when you're launching from a cold place, because NTO freezes pretty easily. Nitric acid is better for that, so it's used in some liquid-fuelled ballistic missile designs, which might have to be launched off of a truck in winter. It gets poorer performance than NTO, in addition to the corrosion problem.

No you are not, you have to make calculations about actually aiming something at mars, you have to be sure there's no debris on the course and even more importantly you would have to be sure that it's possible to survive on both the travel and mars.

Tell me, what is Musk going to do when 1) the first people start dying in space 2) the first people start dying on Mars?

You know what kind of power of pursuasion you need to get people to keep coming back to this? The religious kind. Face it man, people aren't going to go to Mars in large numbers unless it's absolutely necessary. Like, global warming destroying the Earth.

Wouldn't it be nice if shuttles transported us to Mars and back to Earth like some type of space transportation? Of course, it will be a next-gen shuttle and will rely on orbit swings.

That wouldn't be possible even if you could launch all your stuff for free. Living in space is hard and expensive.

>going to Mars at all prior to the advent of artificial gravity

Venus is a much more realistic target. It has an induced magnetosphere to repel radiation. It has a temperate climate and pressure at an altitude of around 55km above the surface. It has 90% of Earth's gravity, which will make it easier for colonists to adapt and survive. Its atmosphere is mostly CO2, which can relatively easily be converted into Oxygen for breathing and buoyancy and Carbon for various carbon based products for expanding colonies. It has solar power in abundance. Gas mining operations could one day supply a Mars colonization effort.

>suffocating in a hole on Mars while you freeze to death and your bones decay.

Why do people keep wanting to do this instead of going to Venus first?

The problem with /sci/ is that you are all to autistic to see past the technical side of things. Elon is a businessman, he is simply saying that by putting more people in space, the cost will go down and it will snowball from there. Basically what Ford did with the automobile. It's a good idea and worth a shot, better than sitting in your basement shooting down anyone who is achieving more than you like a bitter asshole.

>>7501716
What it is exactly that you are going to do there?

>>7501733
>What is it exactly that you are going to do there?

The purpose of colonization is to permanently inhabit new places. Venus is the only realistic target for this purpose at this time.

>>7501748
So there'll be a million people twiddling their thumbs in the clouds of Venus? Who is going to pay for that?

>>7501750
>Who is going to pay for that?

You've missed the point of colonization. If you just want money, invest in Planetary Resources instead. Getting a few asteroids into Earth orbit for mining will be highly profitable (to the point of collapsing commodities markets) and can be done by robots.
