The first manned lunar landing mission, Apollo 11, launched from the Kennedy Space Flight Center (KSC) in Florida via the Marshall Space Flight Center (MSFC) developed Saturn V launch vehicle on July 16, 1969 and safely returned to Earth on July 24, 1969. Astronauts onboard included Neil A. Armstrong, commander; Michael Collins, Command Module (CM) pilot; and Edwin E. Aldrin, Jr., Lunar Module (LM) pilot. The CM, “Columbia”, piloted by Collins, remained in a parking orbit around the Moon while the LM, “Eagle'', carrying astronauts Armstrong and Aldrin, landed on the Moon in the Sea of Tranquility. On July 20, 1969, Armstrong was the first human to ever stand on the lunar surface, followed by Aldrin. During 2½ hours of surface exploration, the crew set up experiments, collected 47 pounds of lunar surface material for analysis back on Earth, planted the U.S Flag, and left a message for all mankind. In this photograph, Armstrong is removing scientific equipment from a storage bay of the LM. The brilliant sunlight emphasizes the U. S. Flag to the left. The object near the flag is the Solar Wind Composition Experiment deployed by Aldrin earlier.

KENNEDY SPACE CENTER, FLA. -- Endeavour settles into place inside the Vehicle Assembly Building (VAB) where it has been moved for temporary storage. It left the Orbiter Processing Facility (OPF) to allow work to be performed in the OPF that can only be accomplished while the bay is empty. Work scheduled in the OPF includes annual validation of the bay’s cranes, work platforms, lifting mechanisms and jack stands. Endeavour will remain in the VAB for approximately 12 days, then return to the OPF.

KENNEDY SPACE CENTER, FLA. -- In bay 3 of the Orbiter Processing Facility, a tool storage assembly unit is being moved for storage in Discovery's payload bay. The tools may be used on a spacewalk, yet to be determined, during mission STS-120. In an unusual operation, the payload bay doors had to be reopened after closure to accommodate the storage. Space shuttle Discovery is targeted to launch Oct. 23 to the International Space Station. It will carry the U.S. Node 2, a connecting module, named Harmony, for assembly on the space station.

KENNEDY SPACE CENTER, FLA. - The orbiter Endeavour rolls out of the Orbiter Processing Facility. It is being moved to Florida Space Authority’s Reusable Launch Vehicle hangar for temporary storage. It left the Orbiter Processing Facility (OPF) to allow work to be performed in the OPF that can only be accomplished while the bay is empty. Work scheduled in the OPF includes modifications to the bay and platform validation in the bay. Endeavour will remain in the hangar for approximately 30 days, then return to the OPF. Endeavour was pulled out of service in December 2003 for Orbiter Major Modification (OMM). OMMs are scheduled at regular intervals to enhance safety and performance, infuse new technology, and, in this case, perform RTF modifications.

OMMs are scheduled at regular intervals to enhance safety and performance, infuse new technology, and, in this case, perform RTF modifications.

KENNEDY SPACE CENTER, FLA. - The orbiter Endeavour arrives inside Florida Space Authority’s Reusable Launch Vehicle hangar where it is being held for temporary storage. Endeavour was moved from the Orbiter Processing Facility (OPF) to allow work to be performed in the OPF that can only be accomplished while the bay is empty. Work scheduled in the OPF includes modifications to the bay and platform validation in the bay. Endeavour will remain in the hangar for approximately 30 days, then return to the OPF.

This aerial photo captures many of the facilities involved in Space Shuttle processing. At center is the Vehicle Assembly Building (VAB). The curved road in the foreground is the newly restored crawlerway leading into the VAB high bay 2. The road restoration and high bay 2 are part of KSC’s Safe Haven project, enabling the storage of orbiters during severe weather. The road circles around the Orbiter Processing Facility 3 (OPF-3) at right center. OPF1 and OPF-2 are just above the curving road. On the left of the VAB, the crawlerway also extends from high bays 1 and 3, past the Launch Control Center, out to the two Shuttle launch pads

KENNEDY SPACE CENTER, FLA. -- On a portion of the once-buried crawlerway that was recently restored, a crawler-transporter with mobile launcher platform on top turns toward the Vehicle Assembly Building (VAB) high bay 2. The road was restored as part of KSC’s Safe Haven project. High bay 2 provides a third stacking area. The primary goal of the Safe Haven construction project was to strengthen readiness for hurricane season by expanding the VAB’s storage capacity. The new area, in high bay 2, will allow NASA to preassemble stacks and still have room in the VAB to pull a Shuttle back from the pad if severe weather threatens. Potential rollouts of the Space Shuttle to the launch pad from high bay 2 will involve making a turn around the north side of the VAB in contrast to the straight rollouts from high bays 1 and 3, on the east side of the VAB facing the launch pads

KENNEDY SPACE CENTER, Fla. -- In the Orbiter Processing Facility bay 3, workers are ready to move a main bus switching unit into Discovery's payload bay. A main bus switching unit is used for power distribution, circuit protection and fault isolation on the space station's power system. The units route power to proper locations in the space station, such as from solar arrays through umbilicals into the U.S. Lab. The unit will be installed on the external stowage platform 2 attached to the Quest airlock for temporary storage. Discovery is targeted to launch mission STS-120 no earlier than Oct. 20.

The STS-100 mission payload is transferred into the payload bay of Space Shuttle Endeavour. A t the top is the Canadian robotic arm, the SSRMS, and below it is the Multi-Purpose Logistics Module Raffaello. In the payload bay, the SSRMS is folded up on a u-shaped space lab pallet. The SSRMS is capable of handling large payloads and assisting with docking the Space Shuttle. It is crucial to the continued assembly of the International Space Station. Raffaello carries six system racks and two storage racks for the U.S. Lab. Launch of mission STS-100 is scheduled for April 19 at 2:41 p.m. EDT

KENNEDY SPACE CENTER, FLA. -- For the first time in Space Shuttle history, a fully stacked Shuttle - Atlantis - moves into high bay 2, on the west side of the Vehicle Assembly Building (VAB). The VAB and nearby rock-paved crawlerway have recently undergone major modifications to provide Shuttle fliglht hardware more storage space and protection - "Safe Haven" - from hurricanes or tropical storms. Atlantis begain moving out of VAB high bay 1 on the east side at 2:59 a.m. EDT. After the successful "Safe Haven" fit check, Shuttle Atlantis is scheduled to roll out to Launch Pad 39B in preparation for the STS-106 launch on Sept. 8.

Fuel cells are located under the forward portion of the payload bay. They make power for the orbiter by mixing hydrogen and oxygen to produce electricity. Fuel cells also create potable water that is pumped into storage tanks for the crew to use in orbit.
