This morning, astronaut Buzz Aldrin (video) talked about his new book, "Magnificent Desolation: The Long Journey Home From The Moon." The book details his amazing journey to the lunar surface, and his battle with depression and alcoholism after his return.
In the 40 years since he walked on the moon, Buzz Aldrin has continued his interest in the space program focusing on space tourism.
In addition, he recently teamed up with the folks from Funny Or Die.com and made a hip-hop music video with Snoop Dogg. We didn't get a chance to get the video during his segment due to breaking news, but it's definitely worth a look!
