The survivor-like TV show was scheduled to air in fall 2001. Participants on the show were to go through training at Russia's cosmonaut(宇航员) training center, Star City. Each week, one of the participants would be eliminated from the show, with the winner receiving a trip to the Mir space station. The Mir crash has ruled out NBC's space plants for now. NASA is against beginning space tourism until the International Space Station is completed in 2006. 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(基础结 构)."Space Island says it will build its space city out of empty NASA space-shuttle fuel tanks (to start, it should take around 12 or so), 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 Earth's. According to their vision statement, Space Adventures plants to "fly tents of thousands 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 form private space stations, and aboard dozens of different vehicles..." Even Hilton Hotels has shown interest in the space tourism industry and the 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 won't 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. In regard to a concept for a space hotel initially planned by Space Island, such a hotel could offer guests every convenience they might find at a hotel on Earth, and some they might not. The small gravitational pull created by the rotating space city would allow space-tourists and residents to walk around and function normally within the structure. Everything from running water to a recycling plant to medical facilities would be possible. Additionally, space tourists would even be able to take spacewalks. Many of these companies believe that they have to offer an extremely enjoyable experience in order for passengers to pay thousands, if not millions, of dollars to ride into space. So will space create another separation between the haves and have-nots? The Most Expensive Vacation Will space be an exotic retreat reserved for only the wealthy? Or will middle-class folks have a chance to take their families to space? Make no mistake about it, going to space will be the most expensive vacation you ever take. Prices right now are in the tens of millions of dollars. Currently, the only vehicles that can take you into space are the space shuttle and the Russian Soyuz, both of which are terribly inefficient. Each spacecraft requires millions of pounds of fuel to take off into space, which makes them expensive to launch. One pound of payload (有效载重) costs about $10,000 to put into Earth's orbit. NASA and Lockheed Martin are currently developing a single-stage-to-orbit launch space plane, called the Venture Star , that could be launched for about a tenth of what the space shuttle costs to launch. If the Venture Star takes off, the number of people who could afford to take a trip into space would move into the millions. In 1998, a joint report from NASA and the Space Transportation Association stated that improvements in technology could push fares for space travel as low as $50,000, and possibly down to $20,000 or $10,000 a decade later. The report concluded that at a ticket price of $50,000, there could be 500,000 passengers flying into space each year. While still leaving out many people, these prices would open up space to a tremendous amount of traffic
