Astronaut Buzz Aldrin in San Diego for book signing

BUZZ ALDRINSAN DIEGO — Astronaut Buzz Aldrin will meet with fans at the San Diego Air & Space Museum today.

Aldrin will sign copies of his new book, “Mission to Mars: My Vision for Space Exploration,” along with co-author Leonard David, according to museum staff. The signing event at the Balboa Park venue is scheduled to start at 5 p.m.

Aldrin, 83, was one of the first men to walk on the moon in the Apollo 11 mission. The other was Neil Armstrong, who died at the age of 82 in San Diego from complications of heart bypass surgery last August.

A New Jersey native, Aldrin was a fighter pilot in the U.S. Air Force before becoming an astronaut.

“Mission to Mars” is at least the sixth nonfiction book on space exploration co-authored by Aldrin since 1973. He also co-authored two science fiction novels.
