The race is on to get more people into space. Billionaires Richard Branson and Jeff Bezos separately shot to the edge of space offering their passengers amazing views of Earth. But how accessible will this sort of space travel be in the years to come, and is it environmentally sustainable? One seat on board the rocket of Amazon and Blue Origin founder Jeff Bezos was auctioned off for an eye-watering $28 million. There are also questions on what the environmental impact of space travel will be. Large rockets need lots of fuel to propel them, so space travel can have a hefty carbon footprint. They tend to be powered by kerosene which is a non-renewable energy source. But some are now launched by using cleaner methods, such as green hydrogen. However, this method is very expensive and more work is still needed to help bring down the costs of this renewable technology. Despite these questions, there are already plans to build the first ever space hotel which should be up and running by 2027. The hotel, called Voyager Station, will have enough rooms for 400 guests, viewing platforms to see the Earth below, a cinema, a spa and a gym.
