>>
>>52953871
Huge part of Russia still has one foot in the stone age, and yet russian space achievements are astounding.Delivering water or electricity for everyone was never anyhow connected to space exploration.

But anyway, many countries have their space programs and no one knows anything about it. There is shitload of satellites from smaller countries around Earth, for example i bet no one ever heard about United Arab Emirates space program - and yet it's there, they placed several satellites around the globe.
>>
>>52953432
>prove country superiority
Well, there was also that thing with the cold war and the nucular bombs and stuff. The star wars program may seem like a joke today but back then the soviets perceived it as an existential threat, since it would theoretically allow the US to wipe them out without fear of retaliation. Owning space pretty much meant you owned the world.

You're the idiot for thinking that science, technology, and the overall progression of mankind are partitioned into neat little boxes.

Leaps in space tech usually bring leaps in earth tech as well. A drop dead easy example is developing the ability to grow crops in space or on other planets (Mars, chiefly). If we do that, we can grow crops practically *anywhere*, even out in the middle of the Sahara desert or at the bottom of the ocean.

Neglecting any given type of science is flat out a bad idea. There's no valid excuse for it, with finance-related reasons being particularly invalid. Instead of sucking away resources from NASA, we should cut back on things like absurdly huge military expenditures and subsidization of big oil. There's enough to go around it it's spent wisely.

It represents a solid, but not insurmountable challenge as well as our best bet for putting eggs in baskets beyond earth to prepare for inevitable (whenever it may be) global catastrophe, both of which are worth a lot.

You can't even call it that. They've designed two satellites, and they were launched by other agencies, one of them from Kazakhstan and the other from Russia.

I'm in Dubai right now and I've seen their "space center", it's nothing impressive. I've been to the ESA facilities in Belgium and they're much more impressive.

I really don't give two fucks about climate change, whether it's real or not.

I live in a cold inland city hundreds of metres above sea level. I hate winter, people literally freeze to death here every year, our cars get raped by the cold weather and we pay big to heat our homes. I have nothing to lose if the Earth returns to an Eocene climate. The people who are going to lose big are all the fuckers pumping carbon into the atmosphere- ie China, India and the United States. I don't see why I don't see why our government is so intent on shooting us in the foot when there are 2.8 billion people who aren't doing jack shit to solve the problem. They'll reap what they sow soon enough, and I'll be laughing as birch forests start growing in the Eastern Arctic.

To the guys arguing about the countries not having landed a rover on Mars, I ask if its really necessary.

Of all the things, I feel that space exploration should be a joint venture between all the space agencies in the world, from the smallest to the biggest. There's no point in every country trying to land a rover on Mar's when its already been done and probably been done better by someone already. It shouldn't be a dick measuring contest but collaboration so that we can learn more, faster.

I liked the part in the Martian where the Chinese helped NASA with their resupply launch. Or in Armageddon where countries get together to face a threat bigger than themselves. I like that kinda shit.

Hell, all non-military scientific endeavors should be collaborative.

the reproduction of food isn't ready their need more genenic variions to suit mars its not easy ya know.
temps are like 0 to 255 that is hard on any plant seriously
also it has to be eatable to humans that is really really hard to do.

also there is the debate about engines whitch ones to use and how should they be used

present rockets can't stay on all the time but we have other things we can use as well as normal rockets

as space has no drag wer can build even the weakest engine and go really realy fast but its about endurance that rocket scientists care about.

besides landing with humans is much harder than machines

>>52952776
no shit machines don't need food or big ships
but no human has left earth to a forienge planet in a long , long time

we can't just rely on machines that's only half the story.
we need human in more than one place to ensure our survival.

>present rockets can't stay on all the time
Saying this is completely pointless because rockets would never ever need to be "on all the time" to begin with. The burn it takes to reach Mars is completed before the rocket even leaves low earth orbit altitudes. Then the rocket is no longer used until it has reached Mars and it's time to achieve orbit. The rocket spends 99% of its time shut off.
>>
>>52973606
>ended up with multiple planets of similar condition in the habitable zone
The probability that there are such planets is very small, let alone that there are multiple in the same solar system.

Besides, Venus would probably still be too hot to live on without the CO2. Is there an estimate to how hot it would be?

I'm talking about the atmosphere on the surface. The surface atmosphere - as opposed to the atmosphere further from the rocky surface.

As I was saying, at those pressures, if the atmosphere was colder, that probe would under liquid carbon dioxide.
>>
>>52975203
No but what are they called in general? Solar system sounds like a really general term.
>>
>>52974446
it'd still be hot but without all the CO2 trapping in the heat it would be a better candidate for colonization than mars since it is more similar to earth in mass. the three major factors going against venus is the abundance of co2, its super slow rotation and a lack of a magnetosphere.
>>
>>52975228
star system
>>
>>52975227
I understand now.

>at those pressures, if the atmosphere was colder
For that to happen, the atmosphere would have to be something besides CO2 that doesn't trap the heat, right?
>>
>>52975265
The mass is important for gravity, I suppose. Why would that be a problem?
>>
>>52975294
So I'm guessing that solar comes from sol, which is our sun, which is why solar system is specifically our system, right?
>>
>>52975333
>For that to happen, the atmosphere would have to be something besides CO2 that doesn't trap the heat, right?

If the planet cools off naturally, over millions of years, or Billions of years, it could happen.

Technically, the atmosphere is Supercritical fluid, so it's not technically a gas... but it's easiest to think of it like a gas.

It's just barely Supercritical because of the high pressure. But if it were colder like under 30° C (86° F), it would be a liquid.

see this chart.

Elaborate. Are you saying that a lot of its heat is due to its own core and not the Sun?
>>
>>52975421
what do you mean? i said venus would be preferable to mars since it has a more similar mass to earth. i'm really not very optimistic about colonizing mars. imo it's a dead planet and it would be foolish to send humans there. i think it would make more sense to work on the technology to create space colonies, then set up space colonies orbiting other planets like mars while using robotics to mine and/or terraform the planets. it's just pissing in the wind to put a bunch of human beings on a lighter planet with little atmosphere and no magnetosphere. future mars colonists are going to have extreme health issues.

OK.
>>
>>52975563

I don't know. I'm just saying IF it cooled off.

It might never... But if the Sun suddenly disappeared, it would still take a long time to cool off because I think there still might be active Volcanoes on Venus, but, again, I'm not sure.

>>52975580
I was asking why Venus would be preferable to Mars based on mass.

I picture planet colonization to start with closed off environments. But how do you get temperatures down to where you can actually start growing plants? Seems impossible.
>>
>>52975580
>>52975622

Actually, at some level in the atmoshere, like 50km off the surface, the temperature, gas constituents, and gravity are almost exactly like the surface of the Earth.

So a Floating City at that altitude would be perfect.

We've found life in harsher environments on Earth.

>>52975750
I'm sure there's materials that can withstand the acid.

Also, how would 2atm pressure feel like? I'm sure with time we could move lower to around 3-4 atms of pressure as our bodies grow stronger.

>>52975754
You mean thin fucking pillars supporting shit? Fuck no. It's unaesthetic as fuck and also looks hella unsafe. What kind of material would be strong enough to support that kinda weight at that size? Carbon nanotubes?

Yeah, its space elevator tier shit. Also, I doubt many people would want to live so far off the surface.
>>
>>52975865
pressure is nothing. Scuba diving records are at like 12 atm.

pressure under a gas and under a liquid are the same thing.
>>
>>52975865
To add,

increased pressure doesn't make it harder to move around since you feel it everywhere equally.

Increased gravity does make it feel harder to move around, though.
>>
>>52976044
>>52976072
I was wondering the same thing. I've scuba dived myself and once you equalize the pressure in your sinuses, it doesn't feel too different.

Thanks for pointing out the confusion between pressure and gravity. I guess we shaved off 10 klicks off the height. 40 more to go.

You know how Helium and Hydrogen float in our atmosphere because they are lighter than it? The breathable air (Nitrogen, oxygen, etc) of our atmosphere is a lifting gas in Venus's atmosphere.
Granted, it probably could float a city on it's own lifting properties alone, but it would tremendously help.

>>52976671
>Ok, but would they be stable?

Ah, I made a bad typo. I meant they probably COULD'NT float a city on its own. I only know air is a lifting gas on Venus, not how stable or strong it would be.
>>
>>52976671
there are three planets in our solar system that are in the habitable zone so i doubt it would be unreasonable to think that somewhere out there among the billions of stars there might exist a star system with multiple planets of similar mass in the habitable zone that all have a molten iron core and large quantities of h2o.
>>
>>52976872
By habitable zone do you mean that the Earth could take the place of Venus or Mars and still sustain some life?
>>
>>52976905
yes. there are lots of variables but both venus and mars are in the habitable zone of our sun. if mars had bulked up enough to maintain a molten iron core it could easily be full of life right now. there used to be lots of water on mars but the core cooled naturally, and without a magnetic field the lighter elements were slowly stripped away by solar winds.

venus had a better mass but more varied issues. it has a screwed up rotation, still no magnetic field despite the mass and without a way to deposit atmospheric CO2 back into the ground, volcanic activity ruined venus' future as a habitable planet.
>>
>>52952194
/g/ space program when?

Our goal: install gentoo on every planets and moons of our solar system.
>>
>>52977098
So the habitable zone itself is fairly common but other variables make planets in the zone inhabitable. So I guess our best bet is to find a planet which is easiest to transform.

Speaking of the habitable zone, what factors determine the distance a piece of rock takes up orbit in around its sun?

I think in that zone, the winds are around 200 mph. But if the "blimp" could ride with the wind, it might not be that big of a deal.

On the surface of Venus, though, the winds are slow. The Supercritical atmosphere is like 5-7% as dense as water here on Earth... that's pretty dense for what is essentially a gas-like state.
>>
>>52977217
all stars have a habitable zone. the habitable zone is defined as the distances from a star where liquid water can form on the surface of a planet. it can be further or closer to a star depending on things like mass/luminosity.

>Speaking of the habitable zone, what factors determine the distance a piece of rock takes up orbit in around its sun?

could you rephrase the question? when a star forms there is a cloud of dust that surrounds it. due to the gravity of the star the dust eventually forms into a disk which then combines in certain spots to form planets. stars also sometimes capture external bodies and if the trajectory is right they become locked into orbiting the star.

But winds mean storms too. It'd be too unreliable. You'd be at the mercy of the weather.

>>52977465
If the habitable zone is so common, why does every 'potential alium encounter' argument have them take our planet cause we're in the zone?

You answered the question. But based on that, shouldn't there be plenty of planets similar to ours? I guess its because detecting planets is pretty difficult. They have no inherent radiation that can be detected.

>>52977612
One theory is that the bottleneck point where most life dies out comes before it gets very advanced. I think that's the most likely.

>>52977727
that makes sense but remember that we barely know our own solar system, how can we even make assumptions about life on other star systems? How about the whole universe? Maybe the universe is full of advanced life and we can't even see it.
>>
>>52977727

lol no, if the earth somehow got destroyed we'd all be dead in an instant. Nothing we can do. There's events in space that could wipe out our entire solar system. We won't be safe from extinction until we've colonized multiple solar systems.

No, humans do have an influence on the climate. However...

* Maximum possible forcing for a doubling of preindustrial CO2 is +1.2C.

* Doubling CO2 levels again would result in a fraction of that forcing because the relevant IR band will be saturated.

* AGW climate models assume a positive H2O feedback to rising CO2. That's how they wind up with +2C to +8C of predicted warming.

* The range is so wide because nobody can agree what the +H2O feedback is.

* "The pause" in warming over the past 18 years suggests that there is no H2O feedback, or at least no significant feedback.

When you cut through all the politics and bullshit, that is the state of the science. We can't model H2O's response because H2O has an extremely chaotic life cycle in the atmosphere. CO2 on the other hand is well mixed and relatively stable.

We can calculate an upper bound on CO2's warming *absent feedbacks* because it is stable and the calculation is basic physics.

We cannot calculate what water will do because it's not stable in the atmosphere. We can't model chaos. We can only plug in assumptions and argue about our assumptions while observational data comes in.

And the observational data does not look good for AGW proponents.*

* I'm going off the satellite and balloon records here because the surface record is fucked beyond belief. Far, far too many problems, assumptions, "corrections", etc. An honest scientist would look at everything and conclude that the surface record margin of error is larger than the claimed warming signal.

The incredible pressure difference means that something that only floats holding up say 10kg here would be able to hold up some magnitude of that there. So, in theory, you could have extremely heavy objects on a series of huge balloons that will float on a very very high pressure cloud of heavier gases. Meanwhile, it's breathable and comfortable for human life where these balloons will be floating. The real questions are a) Where do we get the material to fill these ballasts with and b) what do we make these ballasts out of?

A is presumably easy to answer as the technology it would take for us to travel to the planet and build in that atmosphere imply a fair aptitude for space travel and therefor space mining.

The b, I do not know. If we get good at creating carbon fiber nano tubes or if things like carbyde become particularly prolific, it might be very very easy. Otherwise, I don't know. Diamondillium?
>>
>>52975865
Generally the body consumes material it doesn't use in order to re-purpose that material for something else.
The lack of gravity generally means the lack of muscle usage which results in muscle atrophy.
Bones shrink, muscles shrink, equilibrium are lowered and so on. Everything that we use in the gravity rich environment of Earth is everything we will lose in the free-fall of Earth orbit and the 0g of interstellar travel.

Hence why they have to do resistance training in space.
