Fuck Mars. Let's go to Venus and make cloud cities.

2019-09-25 at 3:08 PM UTCBy comparison to Venus, Mars is a joke and a pipe dream. If we can't successfully colonize Venus first, we have no hopes of colonizing Mars in any meaningful way because it is way more of a technical challenge.
Pretty much the biggest technical challenge on Venus would be how to liberate hydrogen and oxygen from the atmosphere, then use then for combustion and water production. -

Unfortunately Mercury has no clouds (as all the atmosphere has been boiled away) and pretty much every chemical on there has been reacted out so there's no good way to create some sort of sustainable colony on Mercury without massive energy inputs to break up and synthesize materials.
My suggestion for Mercury would be to simply cannibalise it to create a Dyson Swarm, each with an ultra high powered solar beam laser. These swarms and lasers could then be used to direct and focus energy into solar sails for an extremely long distance, or beam huge amounts of energy directly to colonies on other bodies that are further out and don't get much solar power.
Space sailors would request laser assistance if they need a boost while surfing the solar winds.
Or we could focus them like a Death Star and erase New Zealand. -

Doesn't Penis have crazy acid rain storms and pressure and a huge gas cloud around the rocky part where we could actually settle
Cloud City had generally nice weather and some kind of flotation system which is hard enough on Earth, but impossible on a stormy alien planet -

Yeah read my earlier posts. Venus very thick sulphur dioxide clouds and buoyancy has a positive relationship with the square-cube law (increasing the surface area of the buoyant object by a square factor will increase its volume by a cubic factor), we could literally make large teflon coated (for acid resistance) balloons filled with literal Earth air at Earth surface temperatures and pressures and live inside them. We could also fill the balloons with helium except for the human usable spaces. Helium can be extracted on Venus.
The balloons will simply rise to the level of their density in the clouds. You don't need to build on any rocky mountain and you don't need active propulsion to stay afloat.
And yes, the air is still acidic and the temperature can reach as high as 50C or as low as 0C at the altitude where a roughly earth air density balloon. But you can just wear essentially a hazmat suit + breathable air with temperature shielding to walk around outside, as opposed to a pressurised space suit. Your body will take care of the temperature inside the suit, in fact it might get too hot so you might have to vent out some hot air by flushing it out with cool air. Much more comfortable, simpler and cheaper and fewer opportunities for failure. -
2019-09-25 at 6:03 PM UTCAnd you expect balloons to withstand wind speeds of up to 700km/h, in storms that can last for days and circle the entire planet?
Even if we could somehow keep these cities afloat they'd be dragged all over the planet, and would make trips to and from essentially impossible to calculate with modern technology.
Mars is more feasible and that's why literally every expert in the field thinks your proposal is ridiculous.
Venus will be a mining planet. Mark my words. I bet you 5 dolla. We'll be long dead by then so just have your ancestor send the XRP to my ancestor, thanks. -

The space shuttles used to re-enter at 18000km/h, the wind speed itself won't do shit for a properly engineered shell. Obviously it won't just be a rubber balloon, for example rigid airships use metal structures to resist atmospheric pressure rather than just internal gas pressure.
Ultimately keeping it afloat would be simply a matter of buoyancy and scale. You could build a massive external shell out of steel if you wanted, you just need to add enough volume, which dirigibles are amazing at because you need to add proportionally smaller and smaller amounts of surface area per unit volume as you add more and more.
In terms of physics it's not all that much more challenging than a massive oil tanker. The logistics are the problem.Even if we could somehow keep these cities afloat they'd be dragged all over the planet
Drop anchors.and would make trips to and from essentially impossible to calculate with modern technology
In any scenario we are probably going to be using an orbital station as a waypoint anyway, even though the cities could be stationary.Mars is more feasible and that's why literally every expert in the field thinks your proposal is ridiculous.
No it won't and no they don't, you just pulled that out of your asshole.

Venus won't be a mining planet any time in the foreseeable future because surface pressures and temperatures make it extremely difficult for machinery to survive, not to mention the extremely acidic atmosphere and acid rain at the surface. The reinforced probes the Soviets sent lasted ~2 hours before being crushed by sheer pressure. You could probably create more reinforced stuff that lasts longer (or withstands the pressure) at a smaller scale but nothing large scale will happen on the surface of Venus any time soon..
And Mercury is right next door. -
2019-09-25 at 7:36 PM UTCI meant for helium and other gasses.
There's a reason the Venus concept you linked to is ARCHIVED and NOT HAPPENING while NASA and SpaceX both currently have active plans to colonize Mars. -

It's a concept program, it's in the name, the point of concept programs isn't to accomplish them, it's to flesh out what it would take to accomplish them.
It's literally easier to accomplish, and that's why the concept was drawn up in the first.ppace, it was concluded and archived ~8 months ago.

• Orbital mechanics:
- Shorter missions (14 month total duration) with similar propulsion requirements
- Abort-to-Earth available anytime after Venus arrival
• Similar technologies are required and/or can be used: long-duration habitats,
aerobraking/aerocapture, carbon dioxide processing
• Serve as a test case for operations to/at/from another world
The reason why there is hype for Mars is because people really like touching down on shit. -

It would be easier to mine Helium from the moon.
Venus is more feasible, as shown in the above quote by NASA. -

Yeah, we got a new rover launching next year and actual plans to bring humans to Mars in the next 10-15yrs. Russia has plans to get there by 2040.
Venus poses too many variables and is too dangerous to colonize. A solid rock is what we need. The moon obviously will be the first to actually get colonized. -

Sending rovers isn't interest in colonizing Mar, that's just scientific research.
Sending a man to Mars doesn't mean colonization, that's just scientific research.
We were sending probes to Venus decades before the first Mars mission. We sent a moon to the moon decades ago and haven't colonized it.
We don't even have a NASA concept for a person to visit Mars on the same order as HAVOC. -
