The international space station is the third brightest object in the sky, after the sun and the moon. One day there will be even bigger structures in space.

Secondly, materials can be found on the moon and in asteroids. Solar panels can make electricity in space, and this can be used by robots to make these materials into cities. There is water ice on the moon that can be split into oxygen and hydrogen. These gases are good rocket fuel, and people will earn oxygen. Space cities will be useful in many ways. Tourists will enjoy holidays in them, having fun in places where they need to breathe and looking at beautiful views of the Earth, moon and stars, Rich old people could live in them because they can move more easily and live longer in weightlessness Scientists will be played, and the TV rights weigh nothing a lot of money.
