we should send more poo poo to venus. it's isothermal, its atmosphere is dense as hell, we dont know a lot about it because its so hot on the surface also the atmosphere is made of acid, we should fly some poo poo around in its atmosphere and learn some more about it

Isn't Mercury hotter? Or you doing an average so the cold side balances it out?

IIRC Venus's thick atmosphere traps enough heat via the Greenhouse Effect that it is substantially hotter than Mercury, which has barely any atmosphere.

venus is hotter than mercury because of its atmosphere. mercury on the day side is like 800 degrees F while the surface of venus is like upper 800s.

e. yeah ^^

Same.

All these eggheads say things like "we don't have enough stuff we could turn into greenhouse gases to do that" but wait til Elon and Bezos start importing hydrocarbons from the asteroid belt.

Venus is also upside-down and has a longer day than year. That's pretty cool.

And it's easier to get to than Mars, because you don't have to fight the sun's gravity as much. Maybe harder to actually land something on, though.

I thought Mars was harder to land on because the atmosphere is so thin (making deceleration harder)

The main problem seems to be surviving after landing, not just because of the heat but also the intense pressure and possible sulphurous acid rain. Venus is metal as hell though.

Mars has basically the worst case atmosphere of enough to have to worry about but not enough to really take advantage of

Venus, by contrast, has an excellent aerobraking atmosphere. Apart from all of the acid.

the coolest thing about putting floating colonies on venus is how earthlike - admittedly, barring the whole acid cloud thing - it is. towards the top of the clouds, pressure and temperature are earth normal. thanks to the atmospheric density, human breathable gases are lifting gases with about half the power of helium on earth. since the pressure is equalized, any tears or rips in a colony dome wouldn't be immediately catastrophic - you'd just have gases slowly diffusing out. and humans outside of protected spaces wouldn't need to wear pressure suits, just an environmental suit to protect against acid.

You don't need to land on Venus' surface, just on the aerostat.

there’s an esa satellite doing a very close flyby of venus this fall in a gravity assist on its way to mercury; it’ll be interesting to see if they can pick up anything.

I like Venus. I think it's probably the only real chance we have to kinda terraform another planet.

It's got near Earth gravity and a magnetosphere. I think the very low gravity, and lack of magnetosphere are going to make Mars untenable.

Venus has no magnetosphere. You can mitigate that with buildings on Mars.

And about 40% Earth gravity is considerable. We don’t have a good handle on how much gravity you need to avoid turning people into invalids, other than “somewhere between zero and 1 G.)

It has an ionosphere that does basically the same thing. It's more vulnerable to solar storms, but there's a reason it has an atmosphere.

It doesn't have one like Earth does. The paper I read said it was an induced magnetosphere that offers it similar protection.

And yeah, we don't know what 38% gravity will do to fetal development, and childhood development, but my hypothesis that came from my rear end is that it probably won't be good.
