Fly who to the Moon?

摘要

THE $30m Google Lunar xprize has had a slow time of it. Set up in 2007, it originally required competitors to land robots on the Moon by 2012. But the interest in returning to the Moon that the prize sought to catalyse did not quickly materialise; faced with a dearth of likely winners, the xprize Foundation was forced to push back its deadline again and again. Now, though, five competing teams have launch contracts to get their little marvels to the Moon by the end of this year. And as those robotic explorers head into the final straight, a new contest is opening up.
