Kaguya at the Moon
Japan’s unmanned Kaguya spacecraft, also known as SELENE, enters a polar orbit around Earth’s moon with an average altitude of 62 miles. Billed by Japanese space agency JAXA as the most significant lunar mission since the Apollo era, Kaguya carries numerous science experiments, though the public is most captivated by video transmitted back to Earth from two on-board HDTV cameras supplied by television network NHK. Kaguya conducts accurate gravitational mapping of the far side of the moon for the first time, and its own terrain camera obtains high-resolution mapping data, which will later be shared with Google for an online 3-D map of the moon.
