Doesn’t Venus constantly rain sulfuric acid?

Don't think for a second that the Air Force would've retired the SR-71 without a replacement.
No need to conjure up cryptic boogy men.
It’s called the RQ-170.
It’s a black project that fits in the small niche that the SR used to be.

One of the working ideas is to put the humans in some type hibernation on their long voyage to Mars. Does that sound like NASA is on a trajectory to Mars with 15 years?
Oh really? And where, praytell, did you pick up this idea for a working idea of putting people to sleep for a ~9 month trip?

Mars has more potential than Venus. I'm thinking a couple of moons might be more hospitable. I think Titan has an atmosphere. Europa is a possibilty.
There are dwarf planets and asteroids where mining operations might be set up. There may be mining on the moon as well.

For all of the talk about mining in space.....
It’ll never happen until we get developed enough to the point of many space colonies and heavy industry being conducted in space. We are at minimum 100 years from that point. More likely 2-300.
It’s simple economics.
Even with the super cheap offerings of SpaceX that can lift a lot more payload for a fraction of NASA’s budget in the shuttle days, it costs more to lift an ordinary ink pen out of earth orbit than it does to purchase a dry metric ton of iron ore here on earth.

Gotta spend that money on the inner cities to help generate more crime.

NASA needs to exist outside of the power of the president/congress. They get fricked with every 4 to 8 years as a political tool and it really slows down progress.

It may be close to 100 years before we get there but it doesn't have to be. We need to be working on ways to get these payloads into orbit cheaply. There have been alternatives discussed that might be plausible.

Is Rosie Odonnell gonna be on that craft? Please tell me Rosie's gonna be there. Please.

I love the space program, but I’ll believe it when they launch.

Why a theoretical long term colony on Venus is better than Mars
NASA HAVOC Project
Again, I said upper atmosphere, not surface.

Rather than colonization of Venus, develop some kind of plant life that floats in the atmosphere and produces massive amounts of oxygen. Then sit back and watch the magic happen. There's plenty of water on Mars so there's your energy and your oxygen.
The lava tubes are just sitting there waiting for us to occupy them.

It’s a waste of time trying to add atmosphere to mars. Where will the nitrogen come from?
And even if we found a way to overcome the hurtles, the atmosphere will just bleed away.
Remember, mars very likely once had an earth like atmosphere, with oceans to boot. There is a reason it looks the way it does.

No. The atmosphere that we want to modify is Venus.

What is the plan to deal with Venus' slow rotation and hurricane-speed atmospheric winds? It would probably take as many millions of years to tame Venus' runaway greenhouse effect as an artifically created atmosphere on Mars to bleed away. Mars' day is also similar to Earth's. We can actually exist near and utilize Mars' earth unlike Venus.
Mars is clearly the better option.

You would think that they would try a closer object like the moon before landing on Mars. It's weird that we can't even get to the moon.
