Kennedy Space Center Director Robert Cabana, a former space shuttle astronaut, at front right, finds a moment to talk to Apollo astronaut Jim Lovell during a tour for Apollo astronauts and their families of the Vehicle Assembly Building, the facility in which Apollo's Saturn V rockets were processed at NASA's Kennedy Space Center in Florida. The visit followed a ceremony renaming Kennedy's refurbished Operations and Checkout Building for Apollo 11 astronaut Neil Armstrong, the first person to set foot on the moon.

The ceremony was part of NASA's 45th anniversary celebration of the Apollo 11 moon landing. As the world watched, Neil Armstrong and Buzz Aldrin landed in the moon's Sea of Tranquility on July 20, 1969, aboard the lunar module Eagle. Meanwhile, crewmate Michael Collins orbited above in the command module Columbia. For more, visit http://www.nasa.gov/press/2014/july/nasa-honors-historic-first-moon-landing-eyes-first-mars-mission.
