The next big step is to get people to Mars and become a space-faring civilization.

To support a large civilization in space, we will need giant space stations, as planetary surfaces are too small for such a population.

We need to establish a self-sustaining city on Mars, but currently, no amount of money could get you a ticket to Mars; we need to reduce costs significantly.

A Mars city must be able to survive independently if spaceships from Earth stop coming, which means it needs all critical resources.

To be a multi-planetary species, we must ensure that we can return to Mars regularly, not just leave flags and footprints like we did on the Moon.

To create a self-sustaining city on Mars, we need to improve the cost of transportation by at least a factor of a thousand.

The best case for landing a human on Mars is about 5 years, while the worst case is around 10 years, depending on engineering challenges.

Direct democracy, where people vote directly on laws, would be a better system for a civilization on Mars than representative democracy.

The current cost to send one ton to Mars is about a billion dollars, which is too expensive for a self-sustaining civilization.
