Take a look at the costs, you'll find it's absurd.

Going up and down the gravity well is expensive as all hell. You'll never make that back no matter what you find on Ceres or the Moon. Even if it were already stacked in refined bars waiting for you to pick them up!!

OK as a fully subsidized mission with no profitability other than a technology subsidy, sure. But as a proper business? No way.

At least not until we get that space elevator built Wink

There are several projects to build a space elevator until 2050.
I think cost estimates were around 50-100 billion $ with usage of graphene or similar super materials.

It's hard to put a cost estimate on something that doesn't exist. No material has been found which has anywhere near the required strength to weight ratio.

Isn't it easier to do instead of the Elevator start from a space platform? I'm certainly no expert in these matters, but I do not believe in such projects. It seems to me that it just allows you to steal money from the budget.

This is wrong. Super materials that have a a high enough tensile strength already exist.
One of them is graphen. With a taper ratio of 1 and at GEO (around 36.000 km) the burden on graphen would only reach 87% of its tensile strength.

Edit the energy balance sheet of a space elevator doesnt have to be negative.
You could use gravity on the way to back to earth to recollect the energy needed to move the elevator upwards.

Graphene ribbons might do the trick, sure. Might. But do you know how to make them? Can you make them well enough to do so - to deploy them from a geostationary platform? 5000 miles of ribbon and have it hold not only its own weight but all the friction of the atmospheric drag? I don't think we are to the point yet where a cost could be put on this. That fact that people are trying to put "dollar" figures on the costs here kinda proves this point - they aren't talking sense.

I do not believe in such global projects. Still can't ensure the wide dissemination of technologies to make available the energy. It is less costly and more pragmatic and realistic projects.

With inflation that is coming, they better start saving their pennies.

yeah the cost can rise like if you are "ignoring" the surface ocean fishes by hoping to catch a bigger fish 3 km down the ocean.

Lol... this essentially sums up the myth of space mining. Even extracting gold from the sea water (I am not talking about the method proposed by Fritz Haber) may be less expensive than extracting gold from Mars.

Both are interesting ideas, I have never thought of the benefits for the economy from mining resources from comets or planets. We could possibly find a new resource that becomes valuable such as gold which can

greatly influence the economy and boost moral for the interaction with our interplanetary neighbors. In terms of colonizing mars, I believe we are already taking steps to doing so. Elon Musk is leading SpaceX through

the beginning steps of colonizing, or at least, manned trips to mars. With the exponential increase in technology, I do not think it will be long until both colonizing mars and mining space rocks for profit are part of our

society.

Back in the '50s they said we'd have bases on the moon by the turn of the century, with at least monthly flights... if not daily trips. They lied. We aren't even close.

Colonizing Mars or mining the cosmos might be important. But it isn't going to happen. All the propaganda that makes you think that it might, is designed to get you to donate some more money to those propagandists. They leave the money to their kids. But they don't give you the things they promised.

Cool

It could be true, but just classified beyond top secret. There was the UK hacker (Gary McKinnon) that managed to get a crew list of off world officers. Along with ship to ship transfer logs between USSS LeMay and the USSS Hillenkoetter.

Sounds really bogus to me

He said that he was so shocked by the picture that he didn’t think to immediately save it. He also said that the file size was so large that is was difficult to view it on his computer. Eventually his connection was lost, and so was the picture.

Quote

Some of these logs were ship to ship transfers, but he says he was usually smoking pot when he hacked, so that prevented him from remembering the names of the ships.

The rich folks will go for the colonization of mars, they will want a safe haven after they destroy our beloved earth because of their love of power. From the way the world is going nuclear warfare is inevitable, its only a matte of when it will happen. God help us all.

Nuclear war will not happen because most military forces have nukes, and they know if they use the nuclear option, they will open the Pandoras box and get rekt

They are not that dumb

Samson option is interesting to me though

North Korea doesn't have the range for its use on the western world
And other nuclear forces are more or less rational and I don't fear they'll use it

It will, unfortunately not in our lifetime...

If it does, it will only be because we have lost all freedom, and compassion for the poor people of the world.

Cool

We'll still spend that money killing people in Syria, Iran, Iraq etc.
It would be better spent exploring the cosmos

Colonizing mars would be a scientific mission.

Developing the technology necessary to visit and colonize mars would produce many scientific advancements which would benefit everyone.

Asteroid mining is a mission to use taxpayer revenues to explore profitability of mining asteroids for the private sector & has little to do with science.
