And Finally... Spacecraft to crash into moon at 5,600mph tomorrow
Scientists will tomorrow smash a spacecraft on to the surface of the moon at 5,600mph so they can see how much water is present.
The impact will raise a huge dust cloud which is to be analysed to measure water content.
The centaur spacecraft, as heavy as a transit van, will create a crater 30 metres across and five metres deep. It is expected to throw 35 tonnes of lunar debris up to 10 kilometres.
Scientists hope the experiment will show there is enough water in ice crystals beneath the moon's surface to support prolonged manned visits or even settlements.
The experiment will take place in a crater near the moon's south pole, where it is hoped very cold temperatures have preserved ice.
