We wont be able to answer every question, but well do our very best.
Why cant we put a space station on the Moon?

A space station on the Moon could be very useful.
We have only managed to put astronauts on the Moon six times so far.

We are starting to build powerful rockets again.
NASA isalso planningnew missions to take astronauts to the Moon.
However, the International Space Station is only 400km from the surface of the Earth.
The Moon is 384,000km.
On Earth you would make concrete from gravel or sand, cement and water.
These can be melted and mixed together.
Once this mixture cools it produces a solid material that is stronger than many materials we use on Earth.
Scientists have been working on how to grow food in space.
On board the International Space Station, astronauts are carrying out experiments to try togrow vegetablesusing soil pillows.
Getting power on the Moon would be more complicated.
The best way would be to use solar energy from the Sun.
However, the Moon rotates every 28 days.
The panels would get constant sunlight as they can rotate and not be blocked by the planet at all.
Alternatively, we might not even need a base on the surface of the Moon at all.
Instead, Nasa is planning to build a satellite toorbit the moon.
