Alright physics and chemistry nerds, it's game time

Alright physics and chemistry nerds, it's game time.

By 2050, we need to have a man on Venus, using every last bit of science and technology we have at our current disposal.

Clearly, because you'd have to be insane to go straight to Venus before having a man on Mars, lets assume some crazed Pakistani political party is behind this, which would give us in return a 3.4 trillion dollar budget.

The rules are simple:

> at minimum, one man goes to the surface of the planet

> man proceeds to take 5 paces away from the landing craft and plant the flag of Pakistan on Venus ground

> man gets back in shuttle and returns home

What's our game plan?

Is it necessary to EVA from the capsule?
Surely, a mechanical arm manually controlled will count too (just call the capsule his exo-suit).

With that, and some ridiculous plan involving baloons, copters intercepting them, gliders and so on it might be possible to drag him back to a shuttle rocket thing and get him out that slut's grasp...
Lots of steps and risk though. Definitely will be fun.

Technically, that could work, while still being extremely hard.

However, the government of Pakistan was REALLY hoping for that big cheesy American moment of someone hopping towards where the flag would be planted on two feet.

Go at night when it is safe... Oh, wait, that's for the sun...

He's gonna need a few to slow down in time.

why even bother its like putting a man under lava for the craic.

Are tank tread feet allowed?

So what we do is descend from a blimp high up in the atmosphere. Our veneranaut wears something like an atmospheric diving suit with insulation and a cooling system. Current atmospheric diving suits are rated to about 70 atm, so it shouldn't be much of a stretch to make one that can handle 90 atm.

To deal with heat we can cool our suit by melting ice then boiling it. 36 kilograms of ice should be adequate for a 10 minute surface mission, using a quick estimate based upon the thermal resistance of atmospheric diving suits.

>can't hold all of these science and technology

Explain

Good god i wouldn't step foot on venus for a billion dollars.

Landing site: top of Maxwell Montes (tallest mountain on Venus, height approximately 36,960 ft)

Vehicle: cast iron diving bell pressurized to the ambient atmosphere before parachute (not booster)-aided descent.

EVA suit: pic related, a Newtex X60 Advanced Fire Entry Suit. It can withstand temperatures up to 1,500 F, Venus only gets up to 900 F. Air supply would be an off-the-shelf scuba system.

Ascent propulsion: the biggest possible SRBs that can withstand reentry without cooking off.

The main issue isn't getting someone there, it's getting back.

Give money to the media to start a campaign to make denying the venus landing by pakistan a hatecrime

Basically pic related with a man inside and a big daddy style helmet. If the veneranaut doesn't have to walk, we can add more protection.(also it's easier to do heat transfer and stress calculations on cylinders with spherical endcaps than a bloated human body.

So how are you dealing with the 47 bar of pressure? Descent time will be significant, how do you prevent the veneranaut from cooking before reaching the surface?

...

You want to land on the top of a mountain?

> planet is known for two things only, it's heat and it's winds

> attempting a man-operated landing on TOP OF A MOUNTAIN

For a billion?

I'd saw my own foot off for a billion.

Ya, but it'd be cool.

>3 km/h breeze under crushing atmosphere blowing tumblepakis across the surface
I'd pay to see this.

lets get a little bit cheaty
Okay first off shipping materials there won't be too much of an issue with current tech just will cost many Pakistani dollars. Many pre missions to follow the manned one scoping out high landing grounds and good locations. I propose a blimp like apparatus filled with hydrogen. Assuming it is high enough we can still power it solar with very big arrays that will be able to power propellers for altitude control and avioding storms. Power can also be beamed from orbiting solar stations with lasers or microwaves. then our little human comes along we picked a midget in this case for obvious reasons of lower food consumption, smaller required space and comedic effect. This step idk how these able it is but now some spacex falcon relanding shit. The capsule with the person enters orbit using the dense atmosphere to brake and very percise rockets and winglets to match velocities with the blimp maybe with its own bouyant system being deployed. It will only have to match velocities generally close and the blimp can tug it in. this is where the fun begins. The midget is loaded into the blimp as the capsule gets ready for its second purpose a as the descending capsule. The upper atmosphere the blimb is in is much nicer than the surface. Kevlar or similar materials used as cables unreel to the surface itself as the midget enjoys his few days of coping with the new gravity after being in space. while our midget chills a structure on the surface is constructed. Underground building would help the pressure but increase temp so pick your poison. The equipment and structure would be based on diving gear equiptment of modern day. you lower the midget in the capsule into this lower structure on the surface that is preassure regulated and slightly cooler with thick refelctive walls and dumping of ice or cold material on the inside. then our midget walks in suit or rather runs because the temp control wont be perfect slams the flag down and gets back in

capsule assends back to blimp where rocket is waiting to take the upper atmosphere midget to an orbital one where he rondeveus with a tug to take him home

If you were exploring a planet with a dense atmosphere, then some sort of "Rockoon" - which is basically nothing more than a rocket attached to an inflatable balloon, would be the best way to get back into orbit.

They used to be big back in the 50's, before aeronautics got boring.

So, Space Zeppelins

How much would these cost?.

No, you've got it all wrong, thry would be HELL zeppelins

>Pakistani government declares Venus a sovereign pakistani territory.
>Home is now venus.
>The shuttle stays put transmitting video feed of the prank reaction.
>The people of pakistan can now focus on its real goal, the small scale production of nuclear weapons of doubtious quality for fearmongering purposes.

How much would these cost?

Rockoons aren't blimps. They're disposable balloons, once you get high up you just cut them away and ignite your rocket. They're cheap enough, being basically just a balloon and some compressed hydrogen or helium gas.

I was unclear earlier. Venus has a "dense" atmosphere, and it is, at about 60 bar (more or less 60x earth pressure) but it's molecularly only slightly more heavy - 43.45 moles vs 28.97 moles here (basically CO2 vs Nitrogen).

With regard blimps, a lighter than air ship filled with low molecular weight gas at ambient pressure would not be massively easier to make on Venus, however you could maybe make a evacuated void air ship.

Either way, you would not want to rely on a simple rocket to propel you all the way from the surface due to the increased aerodynamic drag you would experience.

I'd be more inclined to make some kind of dome-like structure coated with a billion dollers' worth of heat/pressure/acid resistance. Technically he's still touching the ground, does it only count if he actually goes out into the hellish atmosphere? This way the flag could actually last more than 10 minutes

Throw about 500 bil into materials science so we can get some of that dope shit going

have nasa and spacex work together with a focus on rocket design for 1 round trip, focused purely on maximizing likeliness of survival after the materials things have built up.

So what about windspeed? The wind blows really fast above the clouds and practically nothing at the surface.

Just make the flag out of gold or ceramic. That ain't gonna degrade much even in venus' atmosphere

If we're making a dome, why not just go ahead and build the foundation for Pakistan's (and the world's) first extra-planetary colony?

>we need to have a man on Venus
>the most inhospitable planet in the Solar System
...bcoz why?

This is all much cooler than it has any right to.
>tfw midget veneraunaut riding hell zeppelin rocket contraption making squeaky noises as the planet wants you back

Send midget, it's cheaper.

>If we're making a dome, why not just go ahead and build the foundation for Pakistan's (and the world's) first extra-planetary colony?

"Venus is by far the hottest planet in the Solar System, with a mean surface temperature of 735 K (462 °C; 863 °F), "

OTOH there would be many job opportunities created for HVAC technicians.

>at minimum, one man goes to the surface of the planet
>Venus
>man goes to the surface of the planet
dude what

If Mars is doable then so is Venus.

You would be staying way less time and using modified deep diving equipment the whole time of course. Your spacecraft would also need to be far more dense also, just to reach the surface.

I know it's completely inappropriate due to the fact that we're RPing as Pakistan, but I can't help but hear this playing when our man is going down the bungee rope:

Would make a nice "snowbird" destination
