human race "will be extinct within 100 years", page-16

dont need another planet. thinking Spacestations positioned at Lagrangian points.

But before all that a space elevator to carry stuff cheaply into space.

Then a moon base. We know there is water now so thats a plus.

From the moon base we can start to consider other planets/moons.

Possibly start mining asteroids one day or holidaying by hitching a ride on known asteroids around the sun. Some extreme holidays could be a following a low mass object so your ll bearly be gravitational bound.

All pipe dreams but hey its the general thread!!
