This subject has intriqued me for years, the "best" candidate for such a challenge would have to be Mars

- With Mar's lack of atmosphere at current state and time... how long would the process take to "thicken" the atmosphere... how would we create a greenhouse effect?

- Do we have a "right" to significantly interfere with close and distant planets?


There is speculation that evaporating Mars's available CO2, warming up Mars could be tricky.

A crazy scientist will put 100megatonnes "pure" h-bomb into its planet's pole and Valcanos is actived,ice is melted.

We hope that,we will be able to begin terraforming the mars in next 100years.A sea on the surface of planet is wonderful beautiful!!!

Even though sunlight at Mars averages less than half that on Earth one would have to put ozone or some other filter in Mars's atmosphere to block out the damaging effects of ultraviolet. That ozone would have to be up so we couldn't breathe it, too. Otherwise we would get sunburns and skin cancer a lot more. I suppose we could all walk about in a space suit but that might be inconvenient.

With Mar's current lack of atmosphere, humans wouldnt be able to function without major advancement on particle shielding.. the beating we would take on the surface would kill us instantly, possible mutations.


Now we could walk around in some fancy new technological super suit... but where do we "relax" sleep.

I think the main goal would be to melt the icecaps, plant some seeds, send animals, send humans.. in that order :P


Manned Mission to Mars is scheduled for 2030 now isnt it?

It isn't just the lack of air, but the lack of a magnetic field that will get us zapped. On Earth the magnetic field keeps the solar wind at bay and gives us the aurora. Unless we melt Mars' core we are living underground there no matter. And it isn't worth the energy to melt it's core.

Mars used to have a thick atmosphere. Why it doesn't now hasn't changed. So even if we give it one, it will go away again. Of course if you want to add enough material to make it a 1g planet, then you have a chance. Then all you need is to put a double of our moon in orbit.

Terra forming Venus might be easier. Just need some bacteria that uses heat energy (black smokers on earth) and eats CO2 and dumps it out as limestone or oil. That a a few million years. It may not be that hard to engineer such a critter either.

Honestly can we really in the near future expect to see a "manned" mission to Mars. I watched a really good documentary on it (cant remember it now :@).

In a nutshell so to speak.. even if the flight to Mars was sucessful, the amount of strength and loss of bone mass in zero-g.. it would take months to regain.

I can see the mining of the moon, and asteroids before a manned mission comes to light

I suspect that before we are ready to launch a mission there, the problems of long term exposure to weightlessness will be somewhat solved. They are doing some science on ISS after all. I think the bigger concern though is the exposure to radiation. Not going to be able to lead line the spacecraft walls.

But someone's words come to me:
"We choose to go to the moon. We choose to go to the moon... (interrupted by applause) we choose to go to the moon in this decade and do the other things, not because they are easy, but because they are hard, because that goal will serve to organize and measure the best of our energies and skills, because that challenge is one that we are willing to accept, one we are unwilling to postpone, and one which we intend to win, and the others, too."

We will solve these issues and in so doing create another vast sea of useful things for us here on earth as the Apollo program did.
