I am pretty sure that most of you came across the term- Google Earth- which is a powerful freeware tool that combines the power of Google Search with satellite imagery, maps, terrain and 3D buildings to put the world’s geographic information at your fingertips. This time it is not the Earth that is at the center of their focus, but Moon. Together with NASA Ames Research Center, Google managed to put together collection of lunar maps and charts and named it Google Moon. So far it is limited to the story of the Apollo missions, but that is expected soon to expend as well.
Its pretty good deal despite the fact that it is far from the Google Earth has achieved so far, but am sure that this has future as well. However, the only drawback I could see is that you cannot open Google Moon in your already existing Google Earth module, which requires little extra work, but it functions fully online. Other than that, its fun way of how to expand your knowledge about the Moon and enjoyably spend your free afternoon on Internet.
If you get bored quickly, I suggest you checking out the new feature of Google Earth, that is Exploring The Sky.
