Routine commercial travel to outer space may be the norm as soon as 2012, as the next generation of spacecraft — designed by private sector firms like Virgin Galactic, Orbital Sciences Corp., Space Exploration Technologies Corp. and others — transport adventure-seeking civilians into low-Earth orbit.

There, they can see the sun rise many times a day, and experience the breathtaking curve of planet Earth that only NASA astronauts such as Neil Armstrong or Buzz Aldrin have previously seen. If they want to extend their stay, they can check in to the solar system’s first orbiting hotel, The Galactic Space Suite Hotel, set to open in three years.
