As more countries launch more rockets into orbit for commercial and scientific reasons, the space industry is experiencing rapid growth.

It’s on the verge of an even greater increase as space tourism takes off. The International Space Station is now open to tourists and private companies have developed rockets that can be reused – all meaning more launches into space.
