Today is the 40th anniversary of the first landing on the moon. The mission was carried out by the Apollo 11 crew which carried Neil Armstrong, Michael Collins, and Buzz Aldrin. Armstrong and Aldrin actually walked on the moon, while Collins orbited.
Celebrating the significant event, Google Earth has added the Moon. You can explore the terrain and check out layers that inform about missions to the moon, both manned and non-manned.
Also, for you uber-geeks and history buffs, the History Channel tonight is showing the late Walter Kronkite's coverage of the 1969 landing. Tune in at 8:30pm. My very geeky family is going to.
