(Slate)   NASA says it's time to let go of our dreams of going to Venus, an 850 degree extraterrestrial hell, covered in a dense atmosphere of sulfuric acid and surface pressures that we only see on Earth at depths of about 1 kilometer underwater. Well, okay   ( slate.com) divider line

A balloon filled with breathable atmosphere could float on Venus' atmosphere at an altitude where the temperature would be comfortable.

If I had to choose, I'd much rather establish a colony on the Moon or Mars first.

I'd do the moon or a permanent station at L4 or L5. Mars is a sexier option but Mars offers us few advantages vs the other options.

Yeah, I remember when Steve Austin had to fight the Venus probe.  No one's going there.

What would we make the balloon out of so that the acid in the atmosphere wouldn't eat it.

2017-12-30 10:03:39 PM  
Yeah, until we need a planetary atmosphere's worth of sulphur compounds. I like to think of the other planets as future mines, rather than monuments.

That's what landfills are too. All those complex organics....

No, I won't be there. But my brother's descendants will reap the bountiful harvest of me forgetting to take out the recycling.

Ladies and gentlemen we have had a successful take-off
On this first night flight to Venus
Our flying time will be eight hours
You'll be travelling at a speed of 2,183 miles per second
That is seven and one half million miles per hour
The distance from mother earth to Venus is 60 million miles at this time
To your left you can see the mountains of the moon and right
In the centre, under a huge plastic bubble, Moon City
A boomtown if ever there was one, because of the huge gold and diamond veins
As for Venus, it took almost ninety years to cool down the planet from its 500 degrees To the current pleasant 75 degrees and to transform the atmosphere to make it habitable for Earths people

We could cool the planet down if we unfolded a giant heat shield over the half facing the sun.   Make an artificial ring around Venus, deploy heat shields to reflect the sun's rays... and bingo -- Venus cools down.   Would cost many trillions of dollars and lots of missions to build, but it's do-able.

The question is what to do with Venus after it's cooled enough to set foot on it.  There's no water there.  Lots of CO2 and H2SO4, though.

With a retrograde orbit, a day longer than its year and being that close to the sun, forget about life on Venus. With its distance from the sun and not enough mass for its gravity to hold onto much of an atmosphere, forget about life on Mars. We are in the sweet spot, and if we mess it up, we go extinct.
 
2017-12-30 11:22:42 PM  
These scientists need to eat at taco bell once in a while. The after effects are very similar to Venus.

When we get good at flinging asteroids and comets around, we can bomb Venus with them to rip away some of that atmo, drop the pressure.

Did you see the final two picks?   The comet return mission is interesting, but the other is a nuclear powered quadcopter on Titan.  Risky as hell, but in terms of both science return and public interest it's ridiculous.  Venus may be "Earth's twin" but as FTA notes, it's now a barren hellhole.  Titan is the only other object we know of that has actual liquid rivers and oceans.

Explain to anti-science types that those rivers and oceans are hydrocarbons and you can pretend we're going there to mine them...

Forget the fantasy of going to Mars, too, while you're at it. People don't, and won't for a very long time have the means to overcome the radiation they'd be exposed to in space.

Leaving the protection of Earth atmosphere and magnetic fields may be okay for a few people who knowingly accept the high risks for a short time, but during space travel longer than a few weeks the accumulated dose will increase the risk of stochastic effects (stuff like future cancers and genetic damage to the offspring) by several orders of magnitude -- if one is very lucky.

Any longer than that, or a solar flare will cause radiation poisoning deterministic effects, stuff that even on Earth takes special facilities, trained personnel and huge resources to deal with in very small numbers.

pup.socket: by several orders of magnitude


Actually it is a bit more complex than that, the risk will increase linearly with the absorbed dose, but the higher risk levels are much less tolerable than the low ones. These are nitpicks, really, anything more than a month in outer space will result in acute radiation sickness, and that's the end of it.

Interesting fact: Despite the gravity of Venus being virtually the same as Earth, the Soviet landers didn't even need a parachute. The atmosphere of Venus is so thick, all a lander needed was a ring shaped drag brake around the outside of the probe, and they just plopped down on the surface.

I was promised horny amazons NASA. Now I'm not particular about what planet or moon you get them from, but on those first two points I will not budge.
