CAPE CANAVERAL, Fla. -- Apollo astronauts and their families tour the Vehicle Assembly Building, the facility in which Apollo's Saturn V rockets were processed at NASA's Kennedy Space Center in Florida. The tour followed a ceremony renaming the refurbished Operations and Checkout Building for Apollo 11 astronaut Neil Armstrong, the first person to set foot on the moon. Leading the way through the transfer aisle, from left, are Apollo astronaut Jim Lovell, Neil's former wife Janet, Neil's granddaughter Lily, and Apollo 11 moonwalker Buzz Aldrin. 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.
