Journey into space.
You probably think you'll never be able to go on holiday in space, but in fact space tourism is already here if you're extremely rich! If you want to go into space today, it will be very expensive.An eight-day trip to the International Space Station costs about 20 million.
Fifty years ago, only the richest people could travel by plan,but now 1.6 million people fly every year.So perhaps the same thing will happen with space travel.The USA,Britian,Fance,Germnay,Japan,Russia and India are all planning to build's space planes'. So,in the future,space travel might be a lot cheaper and easier.
