We need to spread across the universe as the sun will one day engulf the earth. There are plenty solutions to all those problems you mentioned, political will is what is needed. Or maybe we can send some self modifying DNA or RNA that will then create ape like lifeforms on other planets :-) Or are we?

Colonies on the Moon have no purpose. Space stations are a

No purpose???

Besides, what's so special about the human race that needs preserving? We seem hell bent on killing one another, or, failing that, dominating each other and inflicting as much grief on the rest of the world as humanly possible. Some do this by not sharing their toys, others by taking away someone else's toys. But the root is always the same. A lack of respect for others if not pure hatred.

If I were an alien race, I'd just pass this planet by.

Maybe lots of things are tried to get stuff into space

Have not heard much recreating mass or organism elsewhere, like 'beam them up Scotty' I would volunteer for mars.. Just for fun and curiosity.

Political will is what has caused many of our problems. So you recommend "hair of the dog that bit you"?

Who cares? We live. We die. Not much changes. Especially in s.e.d.

And will probably keep looking that way until we get there, and get settled in, and find out what we can do there which we can't do down here.

It doesn't kill you fast enough to stop you getting to the moon, and once you are there you do have some gravity, and can get spun in a centrifuge from time to time to get more if you need it. Even cosmic rays don't get far through moon rock,

Not all that soon.

None that you can think of.

The James Webb space telescope isn't.

So far.

Once you've worked out exactly what you want to do, you don't need a human around. We've now worked out how to exploit low earth and synchronous orbits. We may not have covered the full spectrum of stuff that we might do.

Spend most of it on that. Spend a bit on seeing if there is useful stuff we can do a bit further out.

They do, but people have other priorities. Spending money on doing stuff in space isn't going to subtract all that much from what gets spent on solving problems closer to home.

So why aren't they being tackled more effectively? If we spent the money that's now being spent on climate change denial propaganda on cutting CO2 emissions, we'd have a lot less climate change for them to deny.

That's not the real problem, which is the greedy crooks who want to keep on making money out of digging up fossil carbon and selling it as fuel. They want the money now, and can't be convinced that it is doing enough damage to worry about,. Check out John Larkin's opinions on the subject. They are Flyguy idiotic, but he doesn't get the message.

Putting a few more bootprints on the moon won't help. NASA should do something new and useful.

And why now? The sun isn't expanding very fast. Wait a few million years and re-evaluate the situation.

Send me. I die... no big loss. I live, countless data tid bits on long term life on 1/6 gravity, which likely does not destroy blood cells or reduce bone mass. Place it in the shadow of a crater rim wall so the sun can be accessed for power generation and heating, yet the station itself remains out of the light or radiation.

Send up modules for expansion of the original 'station'. Actual useful elements come after, and there could be many.

The modules only need to be about 8 or 10 PSI to exist without a suit. Outside excursions of course still require one.

I'm ready. Gave it thought most of my life. I am cheap. Cheaper than a robot even. Far cheaper than years of training for an expensive crew. They can come after they find out the effects on me.

Yes they should go to Mars .. Elon already has that plan. Long ago NASA had nuclear propulsion to do the Mars trip in a few weeks Politics and nuclear fear stopped it, greens... Push plate nuclear existed too, small nukes detonated behind the spacecraft to push it forward.

I only exist now Tomorrow never comes.

The sun isn't expanding very fast. Wait a few million

Big comet could kill us all here like it did the Dinos or so that say, Or WW3 could... Do not put off till tomorrow what you can do today sort of jive,

A few million? I'm panicking! Oh wait, it's a few _billion_. Phew. :-)

What I meant is that our science and technology will be a lot better in a million years or so. And if we're extinct by then, it doesn't matter.

There have been serious suggestions that we could boost Earth to a higher orbit. We almost have the technology to do that now.

I don't think that putting a few more bootprints on the moon is high on the list of things that they'd tried to do if they got there. John Larkin's grasp of what they might have in mind doesn't seem to be all that comprehensive

Using a rail gun to put a space craft into low orbit around the moon is something you could do in the moon's thin atmosphere.

Once you've got into orbit, all sort of low thrust solutions can get you where you wan to go.

About a billion years before we'll need to do anything energetic. The average life of a vertebrate species is about ten million years, and we should have been able to genetically engineer all sorts of variations on our genome long before then. There's lots of real estate on Jupiter for an organism that was well adapted to the conditions there, though there might be some competition there already.

This is not very informative. The statue of liberty is hollow. Even an engineer would have considerable difficulty estimating it mass without detailed construction information.

The rest of us would have no chance.

Sylvia.

Why? We have robots on Mars already.

NASA should be working on comet detection and deflection, which is arguably useful. ISS could be a staging station for deflectors.

As indeed they are. Comets are just one of a variety of potential impacting objects.

The moon would be more useful. It's easier to get stuff off it's surface, and you could probably make most of the deflecting hardware up there, eventually.

More likely US will use it as high security prison (from movies I have seen). :-)

Well, fusion power has been 30 years out for what, 60 years now? ;)

Even with a very large fusion-powered rocket motor, it would be challenging to do it without ejecting the atmosphere as well.

The idea is to nudge a rock to swing past a bigger rock in the asteroid belt. Do that a bunch of times and eventually swing an asteroid in a hyperbolic loop past earth and transfer some momentum. Do that for a million years or whatever.

That would take very little energy, just a good aim.

Nope. The main asteroid belt orbits are several times further out than the Earth's, so you have to get rid of most of the asteroid's kinetic energy if you want to get its angular momentum low enough for it to reach the orbit of the Earth.

Even then, I seriously doubt there's enough mass in the asteroid belt to do much to the Earth's orbit.

This paper

The solar mass is 2E30 kg, so the asteroid belt's is 2.4e21 kg. The Earth's is 6e24 kg, so the ratio of the total mass of the asteroid belt to that of the Earth is

ratio = 2.4e21 kg / 6e24 kg = 0.0004.

One can do orbital mechanics till one is blue in the face, and never figure out a way to make the Earth's orbit grow by an amount more than a few times that 400 ppm number.
