Spectators watch as space shuttle Discovery, mounted atop a NASA 747 Shuttle Carrier Aircraft (SCA) flies over the National Air and Space Museum’s Steven F. Udvar-Hazy Center, Tuesday, April 17, 2012, in Chantilly, Va. Discovery, the first orbiter retired from NASA’s shuttle fleet, completed 39 missions, spent 365 days in space, orbited the Earth 5,830 times, and traveled 148,221,675 miles. NASA will transfer Discovery to the National Air and Space Museum to begin its new mission to commemorate past achievements in space and to educate and inspire future generations of explorers.

StenniSphere, the John C. Stennis Space Center's visitor center in Hancock County, Miss., features a 14,000-square-foot museum and outdoor exhibits about Stennis Space Center. Designed to entertain while educating, StenniSphere includes informative displays and exhibits from NASA, the Naval Meteorology and Oceanography Command, and other resident agencies. Recently named Mississippi's Travel Attraction of the Year, StenniSphere hosted a quarter of a million visitors in its first year and is a major school field trip destination.

Spacelab is wrapped and ready for transport to the National Air and Space Museum in Washington, DC. Spacelab was designed by the European Space Agency (ESA) for the Space Shuttle program and first flew on STS-9 in November 1983. Its final flight was the STS-90 Neurolab mission in April 1998. A sister module will travel home and be placed on display in Europe. The Spacelab concept of modular experiment racks in a pressurized shirt-sleeve environment made it highly user-friendly and accessible. Numerous experiments conceived by hundreds of scientists on the ground were conducted by flight crews in orbit. Spacelab modules served as on-orbit homes for everything from squirrel monkeys to plant seeds. They supported astronomical as well as Earth observations, for servicing the Hubble Space Telescope and for research preparatory to the International Space Station. One of the greatest benefits afforded by the Spacelab missions was the opportunity to fly a mission more than once, with the second or third flight building on the experiences and data gathered from its predecessors

CAPE CANAVERAL, Fla. -- Tourists check out the Orion launch abort system mock-up, called pathfinder, at the Kennedy Space Center Visitor Complex in Florida. The nearly 45-foot-long mock-up traveled from the U.S. Army's White Sands Missile Range in New Mexico aboard a flatbed trailer, making stops at museums and science centers in Denver, Illinois, Ohio, Pennsylvania and Virginia along the way. Before its cross-country journey, the mock-up was used to practice lifting and stacking operations for the Pad Abort-1 flight test at White Sands. Next, it will be used at Kennedy for similar operations. For information on NASA's future plans, visit www.nasa.gov. Photo credit: NASA/Frankie Martin

John Glenn and NASA Kennedy Space Center Director Bob Cabana sit in the flight deck of space shuttle Discovery in Bay 1 of the Orbiter Processing Facility at NASA's Kennedy Space Center in Florida. Glenn is at the space center to mark the 50th anniversary of being the first American astronaut to orbit the Earth inside the NASA Mercury Project's Friendship 7 capsule on Feb. 20, 1962. Glenn later returned to space in October 1998 as a payload specialist aboard Discovery's STS-95 mission. Glenn's launch aboard an Atlas rocket took with it the hopes of an entire nation and ushered in a new era of space travel that eventually led to Americans walking on the moon by the end of the 1960s. Glenn soon was followed into orbit by Scott Carpenter, Walter Schirra and Gordon Cooper. Their fellow Mercury astronauts Alan Shepard and Virgil "Gus" Grissom flew earlier suborbital flights. Deke Slayton, a member of NASA's original Mercury 7 astronauts, was grounded by a medical condition until the Apollo-Soyuz Test Project in 1975. Shuttle Discovery currently is being prepared for display at Smithsonian’s National Air and Space Museum, Steven F. Udvar-Hazy Center in Chantilly, Virginia.

KENNEDY SPACE CENTER, FLA. -- Two Spacelab modules (end to end) are made ready in the Operations and Checkout Building for shipment to the National Air and Space Museum in Washington, DC. Spacelab was designed by the European Space Agency (ESA) for the Space Shuttle program and first flew on STS-9 in November 1983. Its final flight was the STS-90 Neurolab mission in April 1998. The sister module (first in line) will travel home and be placed on display in Europe. The Spacelab concept of modular experiment racks in a pressurized shirt-sleeve environment made it highly user-friendly and accessible. Numerous experiments conceived by hundreds of scientists on the ground were conducted by flight crews in orbit. Spacelab modules served as on-orbit homes for everything from squirrel monkeys to plant seeds. They supported astronomical as well as Earth observations, for servicing the Hubble Space Telescope and for research preparatory to the International Space Station. One of the greatest benefits afforded by the Spacelab missions was the opportunity to fly a mission more than once, with the second or third flight building on the experiences and data gathered from its predecessors

On April 24, a group traveling with Diamond Tours visited StenniSphere, the visitor center at NASA John C. Stennis Space Center in South Mississippi. The trip marked Diamond Tours' return to StenniSphere since Hurricane Katrina struck the Gulf Coast on Aug. 29, 2005. About 25 business professionals from Georgia enjoyed the day's tour of America's largest rocket engine test complex, along with the many displays and exhibits at the museum. Before Hurricane Katrina, the nationwide company brought more than 1,000 visitors to StenniSphere each month. That contributed to more than 100,000 visitors from around the world touring the space center each year. In past years StenniSphere's visitor relations specialists booked Diamond Tours two or three times a week, averaging 40 to 50 people per visit. SSC was established in the 1960s to test the huge engines for the Saturn V moon rockets. Now 40 years later, the center tests every main engine for the space shuttle. SSC will soon begin testing the rocket engines that will power spacecraft carrying Americans back to the moon and on to Mars.

The astronaut who made that first flight, John Glenn, is at the space center to commemorate that achievement. Glenn orbited the Earth three times in the NASA Mercury Project's Friendship 7 capsule on Feb. 20, 1962. He later returned to space in October 1998 as a payload specialist aboard Discovery's STS-95 mission. Also in the photo are Glenn's wife, Annie, NASA astronaut Stephen Robinson, and Bob Sieck, a former shuttle launch director. Robinson was the payload commander of STS-95.

KENNEDY SPACE CENTER, FLA. -- In the Operations and Checkout Building, Rainer Goercke shakes hands with Norman Jatz in front of the Spacelab Module MD001 as they prepare to close it for the last time before shipment to the National Air and Space Museum in Washington, DC. Goercke and Jatz have been on the Spacelab program since 1979 and were part of the team that first unloaded the module at KSC. Goercke is the only remaining European representative from the German-based Spacelab contractor, ERNO, and Jatz is a mechanical engineering lead from Boeing. Spacelab was designed by the European Space Agency (ESA) for the Space Shuttle program. It first flew on STS-9 in November 1983 and its final flight was the STS-90 Neurolab mission in April 1998.
