Could these two high-profile journeys to the edge of space by wealthy businessmen Jeff Bezos and Richard Branson mean space travel is one step closer for the rest of us?

Well, to go anytime soon, you would need a lot of money. One seat on board billionaire Jeff Bezos's rocket ship was auctioned for 28 million dollars.

Whilst there was nowhere for passengers of these two flights to stop off, the first-ever space hotel is expected to open in 2027. The Voyager Station hotel will float in low orbit, and guests will be able to see the Earth as they move round the planet.

But large rockets need lots of fuel to propel them, so space travel can have a hefty carbon footprint. Historically, rockets have been powered by kerosene, but some are now launched by using cleaner methods, such as green hydrogen.
