Former astronaut Buzz Aldrin cancelled a book signing in New York on Monday (24Jun13) after he was struck down with a bout of influenza.

The spaceman was due to meet fans and autograph copies of his new tome, Mission To Mars, at the Book Revue in Huntington, but he pulled out of the appearance after falling sick.

In a post on his page, he writes, "Sorry! A flu bug caught me so had to cancel my Ny trip & signing (at) BookRevueLi tonight. We will reschedule."
