40th Anniversary of Moon Landing

"That’s one small step for a man, one giant leap for mankind." The astronauts of Apollo 11 gather at the National Air and Space Museum Sunday to commemorate the 40th anniversary of the 1969 Apollo 11 moon landing. From the left are Buzz Aldrin, who was the second astronaut to land on the moon and pilot of the lunar module Eagle; Apollo Mission Commander Neil A. Armstrong, who was the first to land on the moon; Michael Collins, pilot of the command module Colombia; and Ohio Senator John Glenn, who became the oldest astronaut to go to space when he boarded the space shuttle Discovery at age 77 in 1988.
