     A company planning to open the first hotel in space says it is on target to accept its first paying guests

in 2012 despite critics questioning the investment and the length of time for the multibilliondollar project.

     The Barcelonabased architects of the Galactic Suite Space Resort say it will cost $4.4 million for a

threenight stay at the hotel. This price also includes an eightweek training course on an island. During their

stay, guests would see the sunrise 15 times a day and travel around the world every 80 minutes.Galactic

Suite Ltd's CEO Xavier Claramunt says the project will put his company in a leading position of a new

industry with a huge future ahead of it, and forecasts space travel will become common in the future. "It's

very normal to think that your children, possibly within 15 years, could spend a weekend in space" he told Reuters Television.

     A promising space tourism industry is beginning to take shape with construction in progress in New

Mexico of Spaceport America, the world's first facility built specifically for passengers.  British

industrialist Richard Branson's space tours firm, Virgin Galactic, will use the facility to send tourists to

space at a cost of $200,000 a ride.

     Galactic Suite Ltd, set up in 2007, hopes to start its project with a single pod (分离舱) in orbit 280

miles above the earth. "It will take a day and a half to reach the pod, and the passengers will join it for

three days," Claramunt said. More than 200 people have expressed an interest in traveling to the space

hotel and at least 43 people have already reserved it.

     The numbers are similar for Virgin Galactic with 300 people already paid or signed up for the trip, but

unlike Branson, Galactic Suite says they will use Russian rockets to transport their guests into space from

a spaceport to be built on an island in the Caribbean. But critics have questioned the project, saying the

length of time that will be used is unreasonable and also where the money is coming from to support the

project.
