According to the famous futurist, Ian Pearson, space tourism would be made possible by 2050. Companies like Jeff Bezo's Blue Origin and Elon Musk's SpaceX will make it feasible for people to spend a week in the orbit. But it would only be for those who can afford to pay 100 million quid per trip.
Earth is running out of space, the only places to go to are other planets. People will be living on Mars by 2030, wearing special suits and living in capsules. Technology will turn out human society into a multi-planet civilization where humans will move to Mars by the next 10-15 years. There will be certain challenges as well, like radiations, bone density will reduce due to the weightless environment, and other psychological issues will be encountered while we plan about life on Mars.
