The company that pioneered commercial space travel by sending "tourists" up to the International Space Station is planning a new mission: rocketing people around the far side of the moon. The price of a round-trip ticket: $100 million.

The first mission by Space Adventures could happen in 2008 or 2009 and is planned as a stepping stone to an eventual lunar landing by private citizens.

"For the first time in history, a private company is organizing a mission to the moon," Space Adventures CEO Eric Anderson said at a Manhattan news conference Wednesday, a day after space shuttle Discovery safely returned to Earth. "This mission will inspire countries of the world, citizens ... our youth."
