The box is the actual flight hardware scheduled to fly on the Space Shuttle Return to Flight mission STS-114. The fit check is performed to ensure the hardware mates properly with the newly modified LMC and will be returned to NASA’s Johnson Space Center for installation of tile samples in support of the STS-114 mission. The Thermal Protection Detailed Test Objective will enable astronauts to test new on-orbit Thermal Protection System repair techniques. Mission STS-114 is scheduled to launch in May 2005.

Marshall's Neutral Buoyancy Simulator (NBS) is used to simulate the gravitational fields and buoyancy effects outer space has on astronauts and their ability to perform tasks in this environment. In this example, a diver performs a temporary fluid line repair task using a repair kit developed by Marshall engineers. The analysis will determine the value of this repair kit and its feasibility.

CAPE CANAVERAL, Fla. – A view of the flame trench on Launch Pad 39A at NASA's Kennedy Space Center in Florida where repairs of the Fondue Fyre have been made. After launch of space shuttle Atlantis on the STS-125 mission on May 11, a 25-square-foot area of Fondue Fyre from the north side of the solid rocket booster flame deflector was damaged. Some pneumatic lines (gaseous nitrogen, pressurized air) in the area also were damaged and needed to be repaired. The flame trench channels the flames and smoke exhaust of the shuttle's solid rocket boosters away from the space shuttle during liftoff. Fondue Fyre is a fire-resistant concrete-like material that replaced the original flame trench bricks. It can be sprayed on the surface. Pad 39A will be used for the launch of space shuttle Endeavour on the STS-127 mission targeted for June 13. Photo credit: NASA/Jim Grossmann

Launched on July 26 2005, from the Kennedy Space Center in Florida, STS-114 was classified as Logistics Flight 1. Among the Station-related activities of the mission were the delivery of new supplies and the replacement of one of the orbital outpost's Control Moment Gyroscopes (CMGs). STS-114 also carried the Raffaello Multi-Purpose Logistics Module and the External Stowage Platform-2. A major focus of the mission was the testing and evaluation of new Space Shuttle flight safety, which included new inspection and repair techniques. Upon its approach to the International Space Station (ISS), the Space Shuttle Discovery underwent a photography session in order to assess any damages that may have occurred during its launch and/or journey through Space. The mission’s third and final Extra Vehicular Activity (EVA) included taking a close-up look and the repair of the damaged heat shield. Gap fillers were removed from between the orbiter’s heat-shielding tiles located on the craft’s underbelly. Never before had any repairs been done to an orbiter while still in space. This close up of the thermal tiles was taken by astronaut Stephen K. Robinson, STS-114 mission specialist (out of frame). Astronaut Soichi Noguchi, STS-114 mission specialist representing the Japan Aerospace Exploration (JAXA), can be seen in the background perched on a Space Station truss.

On an upper level of high bay 1 of the Vehicle Assembly Building, technicians secure protective material around Atlantis' external tank. The preparations are for future repair work of the hail damage that happened Feb. 27. A severe thunderstorm with golf ball-sized hail caused visible divots in the giant tank's foam insulation and minor surface damage to about 26 heat shield tiles on the shuttle's left wing. Further evaluation of the tank is necessary to get an accurate accounting of foam damage and determine the type of repair required and the time needed for that work. A new target launch date has not been determined, but teams will focus on preparing Atlantis for liftoff in late April on mission STS-117.

STS-44 Mission Specialist (MS) James S. Voss works under the middeck subfloor of Atlantis, Orbiter Vehicle (OV) 104, to repair humidity separator leakage problems. Voss is surrounded by several water tanks and a maze of shuttle wiring and plumbing. Voss earned the nickname of "Bilge Man" because of his time spent on the lower deck tending to the leakage problem. This is the first photo released of a crewmember in this area of the shuttle.

While anchored to a foot restraint on the end of the Orbiter Boom Sensor System (OBSS), astronaut Scott Parazynski, STS-120 mission specialist, participated in the mission's fourth session of extravehicular activity (EVA) while Space Shuttle Discovery was docked with the International Space Station (ISS). During the 7-hour and 19-minute space walk, Parazynski cut a snagged wire and installed homemade stabilizers designed to strengthen the structure and stability of the damaged P6 4B solar array wing. Astronaut Doug Wheelock (out of frame), mission specialist, assisted from the truss by keeping an eye on the distance between Parazynski and the array. Once the repair was complete, flight controllers on the ground successfully completed the deployment of the array.

In the Vehicle Assembly Building, United Space Alliance technician Brenda Morris examines the surface on Space Shuttle Atlantis' external tank where hail damage has been repaired. At the top of the photo is a white/translucent square mold where the foam has been applied and the foam has risen and cured against the mold surface. In late February, Atlantis' external tank received hail damage during a severe thunderstorm that passed through the Kennedy Space Center Launch Complex 39 area. The hail caused visible divots in the giant tank's foam insulation as well as minor surface damage to about 26 heat shield tiles on the shuttle's left wing. The March launch was postponed and has not yet been rescheduled due to the repair process.

In the Vehicle Assembly Building, markers show the hail damage being repaired on the external tank of Space Shuttle Atlantis. The white hole with a red circle around it is a hole prepared for molding and material application. The red material is sealant tape so the mold doesn't leak when the foam rises against the mold. The white/ translucent square mold is an area where the foam has been applied and the foam has risen and cured against the mold surface. The area will be de-molded and sanded flush the with adjacent area.

AS17-137-20979 (12 Dec. 1972) --- A close-up view of the lunar roving vehicle (LRV) at the Taurus-Littrow landing site photographed during Apollo 17 lunar surface extravehicular activity. Note the makeshift repair arrangement on the right rear fender of the LRV. During EVA-1 a hammer got underneath the fender and a part of it was knocked off. Astronauts Eugene A. Cernan and Harrison H. Schmitt were reporting a problem with lunar dust because of the damage fender. Following a suggestion from astronaut John W. Young in the Mission Control Center at Houston the crewmen repaired the fender early in EVA-2 using lunar maps and clamps from the optical alignment telescope lamp. Schmitt is seated in the rover. Cernan took this picture.
