Who wants to melt in boiling sulphuric acid?

[Anonymous No.4953591]

By the way, how would you go about reducing the sulphuric acid in the clouds so the future colonists could live without acid protection suits in the clouds?

Hard to justify a landing mission when the probe will just be destroyed by the atmosphere in less than an hour.

>Baseless opinion.
The Venus In-Situ Explorer was ranked very highly in the decadal survey. Mars exploration is dead, the Mars program has been halved, the follow-up rover is dead, NASA has pulled out of a collaboration with ESA which will put a rover on Mars in 2018 an orbiter in 2016 and aimed at the Mars sample return(the holy grail of Mars missions).
NASA could finally put something on the surface of Venus soon. It was ranked very highly for the next New Frontiers mission, now the largest mission since Flagship missions are dead.

Europa isn't the best place for life any more, a liquid ocean isn't even confirmed. The NASA Europa orbiter (no lander) is dead. ESA will lead exploration of the Jovian moons with JUICE which will study the icy moons and eventually come to orbit Ganymede.

Because surely developing a hardened lander capable of surviving the extremes of the Venusian surface and dealing with little/no orbital relay support won't cost billions of dollars.

And it has to science, too.

I know of nothing more to learn from Venus. Its pretty much hell. In fact I know of nothing more ironic than to name the goddess of beauty and love after Venus and then to realize up close that such a beauty is the Hell of the solar system. Any more missions as to flirt with the goddess would only end in the cuckold financial domination of our planet. While some might find a taste for this kink at such a grand scale, I for one never want that to happen.

>>4953636
Venus is probably too close to the sun to terraform effectively.

[Anonymous No.4953796]

>>4953758
It's right on the edge of habitable zone. I imagine, if terraformed, Venus would be a huge ball of jungle and water vapour.

[Anonymous No.4953818]

>>4953796
Venus will also have comparable gravity to Earth, at about 90% and be 80% covered with oceans instead of 70% in the case of Earth.

Biggest problem would getting a breathable mix out of the atmosphere. It doesn't seem to have enough nitrogen around to make it stable, even if the carbon dioxide is reduced to non-toxic levels.

I said "I imagine" and "if terraformed". I never talked about it seriously, because I know it's kind of out of our reach at the moment. Are you implying a man shouldn't dream?

Hey, kid, knowing the limits of engineering does not make one a luddite. But calling someone one makes you a guttercunt.

SST's aren't commercially viable. Am i a luddite for stating the truth?

[Anonymous No.4953844]

>>4953836

A man should dream of what is possible. Not of what is blatantly impossible and only serves to fulfill pre-ordained romantic notions.

Why don't you go comment on the "Ice sun crashing into a lava sun" thread? It'll let you use that pretty little imagination of yours.

>terraforming venus
>totally impossible

Yes of course, how could we puny humans actually change the climate of a whole planet if we really set our minds on it.

[Anonymous No.4953856]

>>4953844
It is not in my interests to talk about an obviously retarded idea like "what if a sun made of lava crashed to a sun made of ice"? But I admit I'm a hopeless romantic and I really enjoy imagining what we and what our solar system would look like long after I'm gone. Maybe it makes me somewhat of a faggot, but I can't really help it. My imagination is what it is and I'm not exactly keen on stoppin dreaming about useless bullshit because a) it's fun and b) it's a good time-killer.

[Anonymous No.4953860]

>>4953822
Some asteroids have quite a load of nitrogen on them. Crashing a few into there might help.

[Anonymous No.4953879]

>>4953796
Right on the edge of habitable zone my ass. All of it is very arbitrary. The amount of depressurization of the atmosphere in order to make it cold enough would make breathing nigh impossible.

[Anonymous No.4953898]

>>4953855
Because laws of physics.

This is the most retarded shit ever.

Even if you used the entire GDP of the earth and ALL its resources, we can't afford it.

Mars makes much more sense, especially because days don't take 2/3 of an earth year like on venus.

[Anonymous No.4953909]

Scifi is not science, kids. This will also not happen within the next thousand years if it were possible at all.

Bumping to make the Hard-Boiled Realists mad. 50 years from now Venus is going to be a sylvan paradise-world complete with a planet-scale hyperdrive.

not quite
it'd actually reduce the temperature decently

>>4953796
it'd probably be mostly EXTREMELY hot desert, and VERY hot/sticky jungle near the northern latitudes. we're talking like 30% hotter than the gobi desert at the equator

[Anonymous No.4955475]

You would need a moving city on the dark side of Venus, and some way of powering that moving city, forever, to keep it out of the light. It could run on a big track that goes around the planet. Maybe on the opposite side of the planet you'd have solar panels which are also moving on the track, staying IN the sunlight, and sending energy to the city to help it continue moving.

[Anonymous No.4955553]

Venus is within the liquid water zone of Sol. If you could sequester enough greenhouse gasses you could render it habitable. It would get more watts per cubic meter on the surface then you get on earth, giving life more energy to use if you could get the heat down to the point that liquid water could form.

The best way to get the Co2 and other compounds out of the air would be to use extremophile organisms from deep ocean vents altered to survive in the upper layers of the atmosphere, then fall to the surface in death and form carbon rich stone deposits.

Or you know, you could put aerostat colonies of the upper atmosphere.

[Anonymous No.4955562]

>>4955475
Yes, it can be imagined; but you are supposed to say practical things.

Name a similar project we have done on Earth, and we will consider your premise that we can do it on another planet with no people, no tools, no resources, and no ships.

[Anonymous No.4955566]

How would you make it rotate faster? It would be really hard for life to adapt to 243 day/night cycles

Oh, is that all?
You talk as though we have some idea how to alter life;
to make an animal used to extremely high pressure adapt to extremely low pressure.
to change what it lives on and what it produces
to distribute it into another planet's atmosphere in large enough quantities to
-- get this -- change the atmosphere of the whole planet!

>Or you know, you could put aerostat colonies of the upper atmosphere.
Sure is easy to say, huh?
Have we done that, ever? Anyplace?
if we cannot do it HERE, in the place we grew up, why is it so damn easy there?

The point of these suggestions is to name a way they can actually get done.
We have tons of ideas we know we cannot do -- there is no need to dump even more crap on the pile.
Say something we CAN.

[Anonymous No.4955576]

>>4955566
Apparently, we can just make whole cities run on tracks across the entire planet.
Never mind that we are awful at planning a simple city here, or that we cannot manage to make anything small, compact, reliable or mobile at all.
Some people think a city is so easy it's like just building a simple railroad.

In fact, I wonder if he thinks we need rails at all -- if we can put a whole city on rails, certainly we can put it on tires, or make it fly, or, like the other dufus, just put it all in a dirigible!

Have these guys ever SEEN a city?
I'll bet they wouldn't even walk across one, but they are willing to have other people build them AND put them on rails.

genetic modification of extremeophiles isn't that far off, mostly because extremeophiles are very simple in the genetic and structural sense.

the key will be finding something that already does most of what we need, then tweaking the remaining components.
