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.
