Google Moon - Lunar Landing Sites: "In honor of the first manned Moon landing, which took place on July 20, 1969, we’ve added some NASA imagery to the Google Maps interface to help you pay your own visit to our celestial neighbor. Happy lunar surfing."
Fun new Google site. The company also pre-announced that it will start allowing you to search for businesses and home addresses on the moon at the 100th anniversary in 2069.
