Building the future!

Dear Cheap Astronomy – How will we build a lunar base?

The main issue with building on Earth is gravity – that is, if you’d don’t build them properly they

will fall over. With the Moon having one sixth of earth’s gravity, stopping things from falling over

is still important but it’s a much easier thing to accomplish. The main challenge for building

structures for people to live in on the Moon is that those structures will need to retain internal

pressure against a vacuum.

 

Dear Cheap Astronomy – Will travel to Mars ever become routine?

There is a view that whenever we do send astronauts to Mars, they won’t fly there in one

spacecraft. Their launch vehicle from Earth might dock with an orbiting deep space vehicle,

which is built for deep space travel in a vacuum and would never have survived a launch

through Earth’s atmosphere.
