NASA planning manned mission to Venus

Popular science fiction of the early 20th century depicted Venus as some kind of wonderland of pleasantly warm temperatures, forests, swamps and even dinosaurs.
In 1950, the Hayden Planetarium at the American Natural History Museum were soliciting reservations for the first space tourism mission, well before the modern era of Blue Origins, SpaceX and Virgin Galactic.
All you had to do was supply your address and tick the box for your preferred destination, which included Venus.
As revealed by numerous missions in the last few decades, rather than being a paradise, the planet is a hellish world of infernal temperatures, a corrosive toxic atmosphere and crushing pressures at the surface.
Despite this, NASA is currently working on a conceptual manned mission to Venus, named the High Altitude Venus Operational Concept – (HAVOC).
But how is such a mission even possible? Temperatures on the planet's surface (about 460°C) are in fact hotter than Mercury, even though Venus is roughly double the distance from the sun.
This is higher than the melting point of many metals including bismuth and lead, which may even fall as 'snow' onto the higher mountain peaks.
The surface is a barren rocky landscape consisting of vast plains of basaltic rock dotted with volcanic features, and several continent-scale mountainous regions.
It is also geologically young, having undergone catastrophic resurfacing events.
Such extreme events are caused by the build up of heat below the surface, eventually causing it to melt, release heat and re-solidify.
Certainly a scary prospect for any visitors.
Luckily, the idea behind NASA's new mission is not to land people on the inhospitable surface, but to use the dense atmosphere as a base for exploration.

Pretty cool stuff.
However...why don't we work towards actually going back to the moon and setting up a base of operations there, which should be a lot easier, and then work on going to Mars which should be achievable in our lifetimes?

That doesn't seem very responsible.

Probably because they never went to begin with

So, worst environment imaginable. That’s all you had to say.

Come on, man. It's not as if they're talking about going to Ferriday.

The moon missions illustrated the unreasonable expense and danger of manned missions to solar bodies. The push to develop AI missions that are far cheaper and include expendable components is sustaining space exploration. No government is willing to put forth the money needed for a manned mission to Mars, much less Venus.

space is dumb af. either find some aliens or quit wasting money on this shite.

According to black science man, Venus was at one point a planet with moderate temperatures that could well have supported life back in it's heyday. Then something like 10000 volcanoes erupted at once causing an insane amount of CO2 to release. Now hot air can get in, but it cannot escape the atmosphere.
Not sure why this mission is to be manned

Might as well just set eleventy billion dollars on fire

Yeah, let's just resign ourselves to our inevitable extinction as a species.

well, i mean women are from there so, why not go?

How does going closer to the sun help us avoid extinction? Sun=too hot 4 lyfe

By finding out what happened to Venus and ensuring that doesn't happen to us
ETA: however my response was to the a comment saying we should leave all of space alone. So my comment isn't exclusive to venus

im sure people in 1000 years will be thankful we collected rocks from venus for this issue
