Ultimately the immense amounts of nitrogen in Titan's atmosphere could be exported to Mars - if terraforming is ever a serious option for that planet. Immense spheres of gas could be haulled into space and released at the right height for a swingby of Saturn and a plunge in towards Mars.

This is a nice thought, however Mars no longer has a magnetic field. Without a magnetic field, the atmosphere would be eroded away by solar winds.

I've been thinking that in the distant future it may be possible to move Titan it'self into a closer orbit to the sun. And then terraform that world. They say it's like an early Earth, so maybe it's possible. I'm sure terraforming Mars would be an easier task however.

Why not wait until the sun expands....

Damo I doubt that the human race will wait around that long - we´re talking on the time scale of 100´s of millions of years at least!!!!!!!!!! :P

We could transform ourselves by that time into entities of pure energy that don´t need to terraform anything - & a whole lot sooner as well!!!! (probably in less than 1,000,000 years!)

When you warm Titan up, its atmosphere will disappear; it has less surface gravity than the Earth's moon. It's similarity to early Earth is overstated and important details of dissimilarity are being overlooked.

Nitrogen is much more resistant to erosion by the solar wind than hydrogen; however, at a warmer temperature the low gravity of Titan would allow the escape of nitrogen due to higher average velocity of nitrogen molecules.

It's looking better for the non-biological contribution for a large amount of hydrocarbons from the composition of the early Earth's atmosphere.

We should have not found a way to spread our genes beyond our own star system within at least 500 years. If not then we will either have killed ourselves off anyway or developed own own replacements, be they machine or organic. Either way if we are all still sitting around on this one rock in our current human form 500 years from now then we do not deserve to survive. The universe will certainly not morn our passing.

I see we have a collection of contradicting critics? I'll keep watch on this, it is quite entertaining.
