CAPE CANAVERAL, Fla. -- Apollo astronauts and their families examine the mission plaques mounted on the wall in the lobby of the Launch Control Center at NASA's Kennedy Space Center in Florida. The facility houses the firing rooms from which the Apollo countdowns were conducted. Kennedy Director Robert Cabana, at left, led the tour which 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. 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.

CAPE CANAVERAL, Fla. -- At the Kennedy Space Center in Florida, Apollo 11 astronaut Michael Collins gets a close look at an Apollo-era spacesuit following its unveiling in the lobby of the newly named Neil Armstrong Operations and Checkout Building. The facility has been renamed for Apollo 11 astronaut Neil Armstrong, the first person to set foot on the moon. The building's high bay is being used to support the agency's new Orion spacecraft and is the same spaceport facility where the Apollo 11 command/service module and lunar module were prepped for the first lunar landing mission in 1969. Orion is designed to take humans farther than they’ve ever gone before, serving as the exploration vehicle that will carry astronauts to deep space and sustain the crew during travel to destinations such as an asteroid or Mars. The unveiling was part of NASA's 45th anniversary celebration of the Apollo 11 moon landing. As the world watched, Apollo 11 astronauts landed in the moon's Sea of Tranquility aboard the lunar module, Eagle, on July 20, 1969, as the command module, Columbia, orbited overhead.

The building's high bay is being used to support the agency's new Orion spacecraft, which will lift off atop the Space Launch System. Orion is designed to take humans farther than they've ever gone before, serving as the exploration vehicle that will carry astronauts to deep space and sustain the crew during travel to destinations such as an asteroid or Mars. The visit of the former astronauts was part of NASA's 45th anniversary celebration of the moon landing. As the world watched, Neil Armstrong and Aldrin landed in the moon's Sea of Tranquility aboard the lunar module Eagle on July 20, 1969.

CAPE CANAVERAL, Fla. -- Apollo astronauts and their families tour the astronaut crew quarters in the Operations and Checkout Building at NASA's Kennedy Space Center in Florida. Here, from left, Apollo 11 astronaut Michael Collins, NASA Administrator Charles Bolden, and Apollo 8 and Apollo 13 crew member Jim Lovell share a light moment. 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. Besides housing the crew quarters, the building's high bay is being used to support the agency's new Orion spacecraft and is the same spaceport facility where the Apollo 11 command/service module and lunar module were prepped for the first lunar landing mission in 1969.

At a special presentation of the Hammer Award in the IMAX 2 Theater in the Kennedy Space Center Visitor Complex, former Apollo astronauts Neil Armstrong (left) and Edwin "Buzz" Aldrin (second from right) applauded the recipients, Kennedy Space Center and the 45th Space Wing. The Hammer Award is Vice President Al Gore's special recognition of teams of federal employees who have made significant contributions in support of the principles of the National Partnership for Reinventing Government. This Hammer Award acknowledges the accomplishments of a joint NASA and Air Force team that established the Joint Base Operations and Support Contract (J-BOSC) Source Evaluation Board (SEB). Ed Gormel and Chris Fairey, co-chairs of the SEB, accepted the awards for the SEB. The team developed and implemented the acquisition strategy for establishing a single set of base operations and support service requirements for KSC, Cape Canaveral Air Station and Patrick Air Force Base. Armstrong and Aldrin were at KSC to attend a banquet and other activities for the 30th anniversary of the Apollo 11 mission, which landed the first man on the moon
