Astronaut Buzz Aldrin, 79, Raps in New Video

He's walked on the moon and shot down Russian fighter jets over Korea. And now, to make his career complete, astronaut Buzz Aldrin has become ...

A rapper.

The Apollo 11 space hero, the second man to set foot on the moon 40 years ago, has recorded a hip-hop video called "Rocket Experience" produced by rap superstars Snoop Dogg and Talib Kweli.

"I have only two passions, space exploration and hip-hop," the 79-year-old retired astronaut, billed as "Doc Rendezvous," says in a special "making of" clip that accompanies the main video.

"All you need is the rocket experience," Aldrin, looking fit in a tight T-shirt, raps over a slow beat as three backup singers croon.

Aldrin's new memoir, "Magnificent Desolation: The Long Journey Home From the Moon," which chronicles his struggles with depression and alcoholism, was released Tuesday.
