NASA rocket to 'bomb' moon to find water
A US rocket is to crash into the moon on Friday in an experiment scientists hope will provide data about ice hidden in the perpetually dark lunar craters. Astronomers around the world are prepared to capture the impact of the Lunar Crater Observation and Sensing Satellite (LCROSS) into the moon's Caebus crater at 1130 GMT. The rocket will deliberately crash into the moon, kicking up a plume of dust that scientists hope to analyse for traces of water that they believe are abundant in the cold, shadowy craters. The impact is designed to mimic that of the large, natural asteroids that slam into the moon several times a month. The probe belonging to the US space agency NASA is targeting a 100-km wide, 4-kilometre deep crater and is timed to strike when lighting conditions are ideal for observing the impact. The 585-km craft will hit the moon at about 9,000 kilometres per hour creating at impact crater about 2 metres deep. Despite the concerns of some naysayers in the blogospher...
