STS038-S-041 (20 Nov 1990) --- STS-38 Atlantis, Orbiter Vehicle (OV) 104, lands on runway 33 at Kennedy Space Center (KSC) Shuttle Landing Facility (SLF). The main landing gear (MLG) has just touched down on the runway surface as the nose landing gear (NLG) glides above it. The Department of Defense (DOD)-devoted mission came to an end (with complete wheel stop) at 4:43:37 pm (Eastern Standard Time (EST)).

KENNEDY SPACE CENTER, FLA. - During liftoff of Space Shuttle Discovery on mission STS-121 on July 4, a camera captured a small piece of debris (pointed to by the arrow) that is believed to be a part of a shim used on the thermal protection system on the orbiter. The piece did not cause any damage nor will the loss be a concern for the mission or landing.

As the orbiter Columbia (STS-50) rolled down Runway 33 of Kennedy Space Center's (KSC) Shuttle Landing Facility, its distinctively colored drag chute deployed to slow down the spaceship. This landing marked OV-102's first end-of-mission landing at KSC and the tenth in the program, and the second shuttle landing with the drag chute. Edwards Air Force Base, CA, was the designated prime for the landing of Mission STS-50, but poor weather necessitated the switch to KSC after a one-day extension of the historic flight. STS-50 was the longest in Shuttle program historyo date, lasting 13 days, 19 hours, 30 minutes and 4 seconds. A crew of seven and the USML-1 were aboard.

CAPE CANAVERAL, Fla. –- Dark gray clouds hover over the Vehicle Assembly Building at NASA's Kennedy Space Center in Florida, part of a strong weather system that included crosswinds and anvil clouds blowing across the state. The weather concerns prevented space shuttle Endeavour and its crew from returning to Kennedy, the primary end-of-mission landing site. Instead, Endeavour landed safely at 4:25 p.m. at Edwards Air Force Base in California after traveling more than 6.6 million miles in space. The main landing gear touched down at Edwards at 4:25:06 p.m. EST. The nose landing gear touched down at 4:25:21 p.m. and wheel stop was at 4:26:03 p.m. The STS-126 mission was the 27th flight to the International Space Station, carrying equipment and supplies in the Multi-Purpose Logistics Module Leonardo.

The STS-126 mission was the 27th flight to the International Space Station, carrying equipment and supplies in the Multi-Purpose Logistics Module Leonardo. The mission featured four spacewalks and work to prepare the space station to house six crew members for long-duration missions. Photo credit: NASA/Tom Tschida, VAFB

S128-E-007282 (4 Sept. 2009) --- Onboard the International Space Station since July, astronaut Tim Kopra is pictured on the orbital outpost a little less than a week before his scheduled return to Earth. Earlier this week, Kopra changed roles from Expedition 20 flight engineer to STS-128 mission specialist. Kopra came up to the station with the STS-127 crew and participated in a spacewalk on July 18. He will return to Earth aboard the Discovery on a scheduled Sept. 10 landing.

With Commander Kevin R. Kregel and Pilot Steven W. Lindsey at the controls, the orbiter Columbia (STS-87) touched down its main gear on Runway 33 at Kennedy Space Center's (KSC) Shuttle Landing Facility to complete a 15-day, 16-hour and 34-minute-long mission of 6.5 million miles. During the 88th Space Shuttle mission, the crew performed experiments on the United States Microgravity Payload-4 and pollinated plants as part of the Collaborative Ukrainian Experiment.

KENNEDY SPACE CENTER, FLA. -- The Space Shuttle orbiter Atlantis glides out of a morning sky as it prepares to land on Runway 33 at a scheduled time of about 9:23 a.m. EST Jan. 22 to conclude the fifth Shuttle-Mir docking mission and return NASA astronaut John Blaha to Earth after four months in space. At main gear touchdown, the STS-81 mission duration will be 10 days, 4 hours, 55 minutes. This is the 34th KSC landing in Shuttle history. Mission Commander Michael A. Baker is steering Atlantis to a perfect landing, with help from Pilot Brent W. Jett, Jr. Other returning STS-81 crew members are Mission Specialists John M. Grunsfeld, Peter J. K. "Jeff" Wisoff and Marsha S. Ivins. Atlantis also brought back experiment samples from the Russian space station Mir for analysis on Earth

After landing at the Shuttle Landing Facility aboard a T-38 jet aircraft, STS-99 Pilot Dominic Gorie stands ready to prepare for the second launch attempt of Endeavour Feb. 11 at 12:30 p.m. EST from Launch Pad 39A. The earlier launch scheduled for Jan. 31 was scrubbed due to poor weather and a faulty Enhanced Master Events Controller in the orbiter's aft compartment. Over the next few days, the crew will review mission procedures, conduct test flights in the Shuttle Training Aircraft and undergo routine preflight medical exams. STS-99 is the Shuttle Radar Topography Mission, which will produce unrivaled 3-D images of the Earth's surface. The result of the Shuttle Radar Topography Mission could be close to 1 trillion measurements of the Earth's topography. Landing is expected at KSC on Feb. 22 at 4:36 p.m. EST

From left are Mission Specialists Richard Linnehan, James Newman, Michael Massimino and Nancy Jane Currie; Pilot Duane Carey; Commander Scott Altman; Payload Commander John Grunsfeld; and O'Keefe. The crew returned to Earth after a successful 11-day mission servicing the Hubble Space Telescope. Wheel stop occurred on orbit 165 at 4:33:09 a.m. EST. Main gear touchdown occurred at 4:31:52 a.m. and nose wheel touchdown at 4:32:02. Rollout time was 1 minute, 17 seconds. This was the 58th landing at KSC out of 108 missions in the history of the Shuttle program

KENNEDY SPACE CENTER, Fla. -- Space Shuttle Atlantis appears to burst forth from a cocoon of smoke in the Florida marsh lands as it rockets toward space on mission STS-106. The perfect on-time liftoff of Atlantis occurred at 8:45:47 a.m. EDT. On the 11-day mission to the International Space Station, the seven-member crew will perform support tasks on orbit, transfer supplies and prepare the living quarters in the newly arrived Zvezda Service Module. The first long-duration crew, dubbed “Expedition One,” is due to arrive at the Station in late fall. Landing of Atlantis is targeted for 4:45 a.m. EDT on Sept. 19

KENNEDY SPACE CENTER, Fla. -- After arriving at the KSC Shuttle Landing Facility, the STS-108 and Expedition 4 crews wave to the media who waited for comments from the crew. Standing, left to right, are Mission Specialists Linda A. Godwin and Daniel M. Tani, Pilot Mark E. Kelly, and Commander Dominic L. Gorie; Expedition 4 Commander Yuri Onufrienko and crew members Carl E. Walz and Daniel W. Bursch. Top priorities for the STS-108 (UF-1) mission of Endeavour are rotation of the International Space Station Expedition Three and Expedition Four crews, bringing water, equipment and supplies to the station in the Multi-Purpose Logistics Module Raffaello, and completion of spacewalk and robotics tasks. Tani and Godwin will take part in the spacewalk to install thermal blankets over two pieces of equipment at the bases of the Space Station's solar wings. Liftoff is scheduled for 7:41 p.m. EST

S82-33421 (4 July 1982) --- This spectacular view of the NASA 905 transport aircraft taxiing the new space shuttle Challenger was recorded from a T-38 aircraft as the aircraft were heading for Houston, Texas and a combination "meet the Challenger and greet the STS-4 crew" ceremony at Ellington Air Force Base. The STS-4 astronauts-Thomas K. Mattingly II, and Henry W. Hartsfield Jr., were minutes ahead of the tandem in another aircraft. Earlier today they completed a successful week-long stay in space aboard the Columbia. Upon their landing at Edwards Air Force Base, a historical "first" occurred for NASA and this nation. Three shuttlecraft ? The Enterprise, Challenger and Columbia ? were together at one time in the same location. The hardware served as a backdrop for a speech by President Ronald Reagan leading the nation in a special July 4 celebration. Following the stopover in Houston, the Challenger will move onto Florida for processing in preparation for future spaceflights. Photo credit: NASA
