On Friday, the US Space agency will send two unmanned spacecraft into the moon's south pole at 9,000 kmph kicking up a 10 km high shower of debris. Scientists hope the cloud will confirm the presence of enough water necessary to supply future visits by astronauts. Within an hour of the impact, scientists will know whether water was hiding there or not.
Some astronomers may be able to view the impact through a telescope, however, if you would like to watch the mission live via the NASA website, click here http://www.nasa.gov/
NASA will also provide early pictures of the controversial mission.
