Lift off for Indian moon mission
Hard on the heels of the 50th anniversary of the Apollo moon landings, India has successfully launched a rocket into space in an attempt to safely land a rover on the moon.

If successful, the US$146 million mission will allow Indian scientists to carry out studies on the presence of water at the moon's south pole, unexplored by any other nation before.
India hopes to become the fourth nation to soft-land on moon.
