Mankind's space travel

Returning to space or moon or going to Mars are all admiring goals of mankind. We need to pursue them one way or another.

However, given the extremely high costs even going to the moon, there is an important question of how mankind should pursue space travel.

Although it may sound like impossible, mankind needs to focus on new ways of travel to lower the costs of space travel. It means a different race, with the same goals.

We need to reconcile our aspiration goals with the costs of realizing them and come up with better ways of doing things.
