Russia is not alone in its interest in space tourism. There are several projects underway to commercialize space travel. Here are a few of the groups that might take tourists to space:
Space Island Group is going to build a ring-shaped, rotating commercial space infrastructure that will resemble the Discovery spacecraft in the movie 2001: A Space Odyssey. Space Island says it will build its space city out of empty NASA space-shuttle fuel tanks , and place it about 400 miles above Earth. The space city will rotate once per minute to create a gravitational pull one-third as strong as Earths.
According to their vision statement. Space Adventures plans to fly tens of thousand of people in space over the next 10-15 years and beyond, around the moon, and back, from spaceports both on Earth and in space, to and from private space stations, and board dozen of different vehicles...
Even Hilton Hotels has shown interest in the space tourism industry and possibility of building or co-funding a space hotel. However, the company did say that it believes such a space hotel is 15 to 20 years away.
Initially, space tourism will offer simple accommodations at best. For instance, if the International Space Station is used as a tourist attraction, guests wont find the luxurious surroundings of a hotel room on Earth. It has been designed for conducting research, not entertainment. However, the first generation of space hotels should offer tourists a much more comfortable experience.
