Next month at Johnson Space Center you will have a chance to meet Buzz Aldrin, two of the last living members of the Apollo 11 mission, which saw the first manned lunar landing in human history.

Aldrin is the second man to ever walk on the Moon, and that is him in those iconic photos from the surface of the Moon.

Aldrin will be at the JSC signing his newest book, "Mission to Mars: My Vision for Space Exploration" on June 21 at 11 a.m.

Astronauts Aldrin, Neil Armstrong, and Michael Collins made up the Apollo 11 crew, which saw Armstrong and Aldrin both walk on the Moon, on July 20 and 21 in 1969. They collected nearly 50 pounds of rocks on the lunar surface, with Collins piloting the command spacecraft above them.

Armstrong died late last summer at the age of 82.

With the advancing age of the surviving NASA astronauts -- John Glenn is 91 -- opportunities are getting scarce to meet the men who pioneered manned spaceflight. Aldrin himself is 83 years old.
