The US Space agency NASA has successfully steered an empty rocket hull into the moon's south pole in a search for hidden ice. The intentional crash last evening is the first and bigger of two planned collisions that are expected to kick up miles of lunar dust.<br/>The space probe is called Lunar Crater Observation and Sensing Satellite (LCROSS). It has five cameras and four other scientific instruments aboard. <br/>Telescopes across the world were trained to the moon for the event. NASA expects to know whether there was ice below the lunar surface in about an hour.
