CAPE CANAVERAL, Fla. -- This is an inside view of the Air Force Space and Missile Museum's History Center, which is located outside the south gate of Cape Canaveral Air Force Station (CCAFS) in Florida. It contains historic information and displays for each launch complex at CCAFS. Since opening to the public in 1966, the museum has introduced millions of visitors to the history of rocketry and spaceflight. Its primary mission is to collect, restore and exhibit items of historical significance that relate to the development and heritage of U.S. Air Force space launch activities.

KENNEDY SPACE CENTER, FLA. - This is Launch Complex 5_6 blockhouse, now a museum at the Cape Canaveral Air Force Station (CCAFS) in Florida, where long-lost spacesuits were found. A recent venture into a long-locked room at CCAFS uncovered interesting artifacts of a bygone era: retired space suits from Americans who trained in the 1960s to be astronauts aboard an Air Force orbiting reconnaissance laboratory. Two security officers were doing a check of a facility at Launch Complex 5_6 blockhouse. NASA Special Agent Dan E. Oakland and Security Manager Henry Butler, with Delaware North Parks and Resorts, which oversees the museum, discovered a locked room. Space suits from the Air Force’s planned Manned Orbiting Laboratory (MOL) program were found in the room Begun in 1964, the MOL program was an Air Force initiative that would have sent Air Force astronauts to a space station in a Gemini capsule. After spending a few weeks in orbit, the crew would undock and return to Earth. A test launch from Complex 40 on Nov. 30, 1966, of a MOL was conducted with an unmanned Gemini capsule. The MOL was constructed from tankage of a Titan II rocket. The operational MOL was planned to be launched into a polar orbit from Vandenberg Air Force Base in California. The Air Force abandoned the program in 1969, but the program produced a great deal of technological development, and three groups of military officers trained to be MOL astronauts. When the program was cancelled, seven of the younger astronauts were transferred to the agency’s human space flight program and went on to have standout careers. Among them were Robert Crippen, pilot of the first Space Shuttle mission, and Richard H. 'Dick' Truly, who later became NASA Administrator.

KENNEDY SPACE CENTER, FLA. -- Waiting for the arrival of the Liberty Bell 7 after its raising from the ocean floor. Liberty Bell 7 launched U.S. Air Force Captain Virgil "Gus" Grissom July 21, 1961 on a mission that lasted 15 minutes and 37 seconds before sinking to the floor of the Atlantic Ocean, three miles deep. It lay undetected for nearly four decades before a Discovery Channel expedition located it and recovered it. The space capsule is now restored and preserved, and part of an interactive exhibit touring science centers and museums in 12 cities throughout the United States until 2003. The exhibit includes hands-on elements such as a capsule simulator, a centrifuge, and ROV pilot.

Daedalus - Last Dryden flight with Glenn Tremml

Daedalus Project's Light Eagle - Human powered aircraft

Four different versions of the F-16 were used by Dryden in the 1990s. On the left and right sides are two F-16XLs. On the left is the F-16XL #2 (NASA 848), which is the two-seat version, used for advanced laminar flow studies until late 1996. On the right is the single-seat F-16XL #1 (NASA 849), used for laminar flow research and sonic boom research. (Laminar flow refers to smooth airflow over a wing, which increases lift and reduces drag compared to turbulent airflow). Between them at center left is an F-16A (NASA 816), the only civilian operated F-16. Next to it at center right is the U.S. Air Force Advance Fighter Technology Integration (AFTI) F-16, a program to test new sensor and control technologies for future fighter aircraft. Both F-16XLs are in storage at Dryden. The F-16A was never flown at Dryden, and was parked by the entrance to the center. The AFTI F-16 is in the Air Force Museum.

CAPE CANAVERAL, Fla. -- Members of the United States Air Force 45th Space Wing Honor Guard and more than a dozen 9/11 first responders take part in "The National 9/11 Flag" stitching ceremony in the Debus Conference Facility at the Kennedy Space Center Visitor Complex in Florida. The contributions of NASA, Kennedy Space Center and the state of Florida were stitched into the fabric of the American Flag, which was recovered near ground zero following the World Trade Center attacks on Sept. 11, 2001. The "New York Says Thank You Foundation" is taking the flag on a cross-country journey to be restored to its original 13-stripe design using pieces of fabric from American flags destined for retirement in all 50 states. Once the flag is restored, it will become a permanent collection of the National September 11 Memorial Museum being built at the World Trade Center site. Photo credit: NASA/Kim Shiflett

CAPE CANAVERAL, Fla. – The Shuttle Carrier Aircraft transporting space shuttle Discovery flies over the hangars in the Industrial Area on Cape Canaveral Air Force Station after taking off from Kennedy Space Center’s Shuttle Landing Facility at 7 a.m. EDT. The duo are heading south to fly over Brevard County’s beach communities, offering residents the opportunity to see the shuttle before it leaves the Space Coast for the last time. The aircraft, known as an SCA, is a Boeing 747 jet, originally manufactured for commercial use, which was modified by NASA to transport the shuttles between destinations on Earth. This SCA, designated NASA 905, is assigned to the remaining ferry missions, delivering the shuttles to their permanent public display sites. NASA 905 is scheduled to ferry Discovery to the Washington Dulles International Airport in Virginia on April 17, after which the shuttle will be placed on display in the Smithsonian's National Air and Space Museum Steven F. Udvar-Hazy Center. For more information on the SCA, visit http://www.nasa.gov/centers/dryden/news/FactSheets/FS-013-DFRC.html.

The wingless, lifting body aircraft sitting on Rogers Dry Lake at what is now NASA's Dryden Flight Research Center, Edwards, California, from left to right are the X-24A, M2-F3 and the HL-10. The lifting body aircraft studied the feasibility of maneuvering and landing an aerodynamic craft designed for reentry from space. These lifting bodies were air launched by a B-52 mother ship, then flew powered by their own rocket engines before making an unpowered approach and landing. They helped validate the concept that a space shuttle could make accurate landings without power. The X-24A flew from April 17, 1969 to June 4, 1971. The M2-F3 flew from June 2, 1970 until December 22, 1972. The HL-10 flew from December 22, 1966 until July 17, 1970, and logged the highest and fastest records in the lifting body program.

CAPE CANAVERAL, Fla. – Astrophysicist Dr. Neil deGrasse Tyson with the American Museum of Natural History’s Hayden Planetarium in New York, speaks to a group of Tweetup participants at the Kennedy Space Center Visitor Complex in Florida during prelaunch activities for the agency’s Gravity Recovery and Interior Laboratory (GRAIL) mission. Participants toured NASA’s Kennedy Space Center and got a close-up view of Space Launch Complex 17B at Cape Canaveral Air Force Station. The tweeters will share their experiences with followers through the social networking site Twitter. GRAIL will fly twin spacecraft in tandem around the moon to precisely measure and map variations in the moon’s gravitational field. The mission will provide the most accurate global gravity field to date for any planet, including Earth. This detailed information will reveal differences in the density of the moon’s crust and mantle and will help answer fundamental questions about the moon’s internal structure, thermal evolution, and history of collisions with asteroids. The aim is to map the moon’s gravity field so completely that future lunar vehicles can safely navigate anywhere on the moon’s surface. Launch is scheduled for 8:37:06 a.m. EDT Sept. 8.

A Bell P-59B Airacomet sits beside the hangar at the National Advisory Committee for Aeronautics (NACA) Lewis Flight Propulsion Laboratory. In 1942 the Bell XP-59A Airacomet became the first jet aircraft in the US. The Airacomet incorporated centrifugal turbojet engines that were based on British plans secretly brought to the US in 1941. A Bell test pilot flew the XP-59A for the first time at Muroc Lake, California in October 1942. The General Electric I-16 engines proved to be problematic. In an effort to increase the engine performance, an Airacomet was secretly brought to Cleveland in early 1944 for testing in the Altitude Wind Tunnel. A series of tunnel investigations in February and March resulted in a 25-percent increase in the I-16 engine’s performance. Nonetheless, Bell’s 66 Airacomets never made it into combat. A second, slightly improved Airacomet, a P-59B, was transferred to NACA Lewis just after the war in September 1945. The P-59B was used over the next three years to study general jet thrust performance and thrust augmentation devices such as afterburners and water/alcohol injection. The P-59B flights determined the proper alcohol and water mixture and injection rate to produce a 21-percent increase in thrust. Since the extra boost would be most useful for takeoffs, a series of ground-based tests with the aircraft ensued. It was determined that the runway length for takeoffs could be reduced by as much as 15 percent. The P-59B used for the tests is now on display at the Air Force Museum at Wright Patterson.

In the center foreground of this 1953 hangar photo is the YF-84A (NACA 134/Air Force 45-59490) used for vortex generator research. It arrived on November 28, 1949, and departed on April 21, 1954. Beside it is the third D-558-1 aircraft (NACA 142/Navy 37972). This aircraft was used for a total of 78 transonic research flights from April 1949 to June 1954. It replaced the second D-558-1, lost in the crash which killed Howard Lilly. Just visible on the left edge is the nose of the first D-558-2 (NACA 143/Navy 37973). Douglas turned the aircraft over to NACA on August 31, 1951, after the contractor had completed its initial test flights. NACA only made a single flight with the aircraft, on September 17, 1956, before the program was cancelled. In the center of the photo is the B-47A (NACA 150/Air Force 49-1900). The B-47 jet bomber, with its thin, swept-back wings, and six podded engines, represented the state of the art in aircraft design in the early 1950s. The aircraft undertook a number of research activities between May 1953 and its 78th and final research flight on November 22, 1957. The tests showed that the aircraft had a buffeting problem at speeds above Mach 0.8. Among the pilots who flew the B-47 were later X-15 pilots Joe Walker, A. Scott Crossfield, John B. McKay, and Neil A. Armstrong. On the right side of the B-47 is NACA's X-1 (Air Force 46-063). The second XS-1 aircraft built, it was fitted with a thicker wing than that on the first aircraft, which had exceeded Mach 1 on October 14, 1947. Flight research by NACA pilots indicated that this thicker wing produced 30 percent more drag at transonic speeds compared to the thinner wing on the first X-1. After a final flight on October 23, 1951, the aircraft was grounded due to the possibility of fatigue failure of the nitrogen spheres used to pressurize the fuel tanks. At the time of this photo, in 1953, the aircraft was in storage. In 1955, the aircraft was extensively modified, becoming the X-1E. In front o
