The tray corner clamp blocks are un-anodized aluminum and that alone accounts for the major difference in color between the corner clamp blocks and the center clamp blocks. The MAP experiment, located in the left end of the integrated tray, shows signs of contamination but otherwise seems intact. The mesh support, the detector foils and the bond joints are intact and show no sign of physical failure. There are some darker contamination stains in areas on the diecast aluminum frames where adhesive residue remained after prelaunch cleaning. Some color differences are observed when comparing this photograph to the prelaunch and flight photographs. These differences seem to be due to lighting direction and intensity as well as colors of objects in the surrounding area.

When comparing this photograph with the prelaunch photograph, very little difference can be seen. A brown stain is visible around some of the fasteners and on mounting plates. The stain has been attributed to outgassing and contamination from the LDEF and experiment related materials being flown. When compared to the prelaunch photograph, the C09 integrated tray seems to be in excellent condition. The Atomic Oxygen Stimulated Outgassing experiment seems to have changed little over the sixty nine (69) month LDEF mission. The experiment seems to be intact. The grayish appearance of the experiment coverplate is thought to be the results of lighting direction and intensity. The anodized aluminum disks, located in the openings at the four corners, appear to be brighter than in the pre-launch photograph. This is seems to be due to a reflection of the white cargo bay liner in the disks.

A very light stain is present on the white paint dots on experiment tray clamps along the lower edge of the tray. The color of the white thermal control paint on the IGE has changed and now varies from white to differing shades of brown. The darker brown areas on the experiment baseplate, around the grid voltage cable connectors, appear to have come from contaminants flowing from inside the LDEF. The shadows from the tray sidewalls hide most of the dark stain in the upper right corner of the tray.

The experiment utilizes seven (7) canisters containing high-purity beryllium copper collecting foils, three (3) located in peripheral trays and four (4) located in trays on the space end of the LDEF, to meet experiment objectives. The active portion of the experiment consist of canister electronic timing devices and pyrotechnic cutters that control the exposure time of each collector foil. An electronic voltage multiplier system provides a bias voltage to the grid network located above the beryllium copper collecting foils.The batteries and the electronics are housed beneath the experiment baseplate facing the LDEF interior. The white painted surface area within the LDEF tray provides the optical properties required to maintain the experiment components within temperature limits. The two (2) rectangular openings in opposite corners of the experiment baseplate provide the mountings for the ground support equipment test connectors. A white grid voltage connector box, mounted on the side of each canister housing, provides the termination point for the cables running from the grid voltage box beneath the baseplate. The canister housing is a welded aluminum structure with aluminum mounting flanges. The experiment components are assembled using non-magnetic stainless steel fasteners. The aluminum housing cover, removed prior to flight, protects experiment components from damage and large particle contamination during ground handling.

The OMS pod and a small part of the aft bulkhead in the Orbiter's cargo bay can be seen along the left side of the photograph. The three (3) black rectangles on the OMS pod are locations where thermal protection tiles were lost during the Orbiters ascent to orbit. During the LDEF mission, the F06 experiment tray surface was at an angle of approximately eighty-two (82) degrees to the orbital velocity vector and therefore exposed to a higher atomic oxygen flux than if parallel with the velocity vector. The white paint dots and experiment tray clamps along the upper edge of the tray appear to be clean. However, a brown stain is present on the white paint dots and experiment tray clamps along the lower edge of the tray. The color of the white thermal control paint on the IGE has changed from white to differing shades of brown. The brown stain on the tray sidewalls and all experiment hardware appears to be a product of contamination and the space environment. A hand print, not visible in the prelaunch photograph, can be seen on the baseplate in the lower half of the experiment tray. The white dot near the lower corner of the end sidewall is a reflection of the GSE test connector located in the lower left corner of the baseplate. The two (2) white dots on the experiment baseplate, near the left end of the tray, appear to be imperfections in the photograph since they were not observed during post-flight inspection..The insulation on the grid voltage cable that was transparent prior to launch is now a light tan color.

A very light contamination stain is present on the experiment tray flanges and on the most of the visible LDEF structure. The exception being a much darker stain on the structure adjacent to thermal covers that provide venting for the LDEF interior. The paint dot adjacent to the thermal cover vent area is heavily coated with the brown contamination stain while the paint dot adjacent to the center end cover plate has a very light coating. The color of the white thermal control paint on the IGE has changed and now varies from offwhite to a dark brown. The darker brown areas on the experiment baseplate, around the grid voltage cable connectors, appear to have come from contaminants flowing from inside the LDEF. A dark stain area can be seen on the tray's lower sidewall and in the upper left corner of the tray. A lighter stain coats portions of the experiment baseplate and the outside of the canister housing. A beryllium copper collector foil is clearly visible within the canister housings as are the baffles and reflected light from the fine wire mesh grid near the top of the canister housing.

The experiment utilizes seven (7) canisters containing high-purity beryllium copper collecting foils, three (3) located in peripheral trays and four (4) located in trays on the space end of the LDEF, to meet experiment objectives. The active portion of the experiment consist of canister electronic timing devices and pyrotechnic cutters that control the exposure time of each collector foil. An electronic voltage multiplier system provides a bias voltage to a wire mesh grid located above the beryllium copper collecting foils.The batteries and the electronics are housed beneath the experiment baseplate facing the LDEF interior. The white painted surface area within the LDEF tray provides the optical properties required to maintain the experiment components within temperature limits. The two (2) rectangular openings in opposite corners of the experiment baseplate provide the mountings for the grid voltage box and for the ground support equipment test connectors.

The larger fragments of the VDA layer observed in the flight photograph were disturbed during post retrieval operations and became many small aluminum particles. The white paint around the outer edges of the solar cell modules appears to have changed little. Impact craters are visible as black or white specks in many locations on the degraded dielectric surfaces. One of the most noticeable is in the dielectric surface in the upper right corner.

The white paint dots on the center clamp blocks of the experiment trays right flange and lower flange appear to be slightly discolored. The LDEF structure, top intercostal, has a dark brown discoloration adjacent to the black thermal panel. Aluminum particles from the degraded CVCHPE thermal blanket are also visible in this area. The Cascade Variable Conductance Heat Pipe Experiment (CVCHPE) occupies a 6 inch deep LDEF peripheral experiment tray and consist of two series connected variable conductance heatpipes, a black chrome solar collector panel and a silvered Teflon radiator panel, a power source to support six thermistor-type temperature monitoring sensors and actuations of two valves. Fiberglass standoffs and internal insulation blankets thermally isolated the experiment from the experiment tray and the LDEF interior. The outside of the CVCHPE, except the collector and radiator panels, was covered with an aluminumized Kapton multilayer insulation (MLI) blanket with an outer layer of 0.076 mm thick Kapton. The two patches of thin film materials, part of an atomic oxygen experiment (see S1001) by NASA GSFC, were attached to the cover of the external thermal blanket with Kapton tape. The experiment was assembled and mounted in the experiment tray with non-magnetic stainless steel fasteners. The external CVCHPE materials have changed significantly. The Kapton on the thermal blanket aluminized Kapton cover appears to be completely eroded, except under Kel-F buttons used to secure the blanket, leaving only the very thin vapor deposited aluminum coating as a cover. Parts of the aluminum coating residue has moved to cover a portion of the black solar absorber panel and also areas of the trays upper and lower flanges. The shadow on the tray lower flange would indicate that the aluminum extends several inches out of the tray envelope. One of the two thin film atomic oxygen experiment patches is gone and the other does not appear to be securely attached. The layer of Kapton tape over the thin film strips appears to be eroded with only the adhesive remaining. The remaining atomic oxygen experiment materials have changed colors and most appear to be severely degraded. The silvered Teflon coating of the radiator panel appears diffuse with a light brown discoloration over most of the surface. The white, evenly spaced, discolorations along the vertical centerline and across the top of the panel appear to be above counter sunk flat head screws used to assemble the experiment. The black spots on the radiator panel appear to be impact craters where the impact penetrated the Teflon material and exposed the silver beneath to the atomic oxygen flux. Particles of the degraded thermal blanket material appear to be adhered to the surface of the radiator panel.

The color of the white paint dots on the exper- iment tray clamp blocks appear to be unchanged. The LDEF structure, the intercostal on the right, has a dark brown discoloration adjacent to the black Earth end thermal panel. Aluminum pieces of the degraded CVCHPE thermal cover that were shown lodged in the vent area between the intercostal and the black thermal panel in the flight photograph are gone.

The experiment was assembled and mounted in the experiment tray with non-magnetic stainless steel fasteners. The external surface of the CVCHPE has changed from that observed in the flight photograph. The thin vapor deposited aluminum coating, left after the Kapton eroded, is essentially gone with only fragments left near the edges of the thermal blanket. Pieces of a layer of Dacron mesh (bridle vail) material, used to separate the thermal cover from the thermal blanket and between thermal blanket sheets of aluminized Kapton, are visible along the edges of the blanket and near Kel-F buttons used to secure the blanket. A large fragment of the material is folded over the left side of the radiator panel. The large area of discoloration on the right side of the black solar absorber panel appears to be approximately the same shape as the aluminum coating that covered the area in the flight photograph. The orientation of the remaining thin film atomic oxygen experiment patch would indicate that the patch is attached to the Dacron mesh and that the attachment is very fragile. The layer of Kapton tape that covered the ends of the thin film strips appears to be eroded with only the adhesive remaining. The remaining strips of the atomic oxygen experiment materials have changed colors and most appear to be severely degraded. The silvered Teflon coating of the radiator panel appears diffuse with a light brown discoloration over most of the surface. The white, evenly spaced, discolorations along the horizontal centerline and along the edges of the panel appear to be above counter sunk flat head screws used to assemble the experiment.

The Space-Based Radar (SBR) Phased-Array Antenna Experiment occupies a six (6) inch deep LDEF end corner tray located on the space end of the LDEF. The SBR Phased-Array Antenna experiment consists of both passive and active parts. The passive part , shown in the left half of the experiment tray, investigates the dimensional stability of Kapton when exposed to induced stresses in the space environment. Continuous and spliced specimen of both plain Kapton (127 um thick) and glass reinforced Kapton (196 um thick) will be exposed for the entire mission. The Kapton specimen array contains eight 2.54-cm-wide specimen and sixteen (16) 1.27-cm-wide specimen. The specimen are stretched over an aluminum roller assembly and utilize a spring loaded mechanism to provide preselected stresses. An aluminum support structure houses two (2) identical set of specimen, one exposed to the total environment and one shadowed.

Thermal control was accomplished by attaching an aluminized Kapton thermal cover on the tray bottom (the Kapton facing the LDEF interior), placing the aluminum cylinder support structure on thermal isolators and covering the experiment with a thin (5 mil) silvered Teflon thermal cover. The silvered Teflon cover was supported by an aluminum frame, an integral part of the experiment structure, and held in place by Velcro pads selectively located on the frame and on the back of the cover. The copper colored strip extending over the trays upper flange is a copper coated pressure sensitive tape used to provide an electrical ground between the experiments thermal cover and the LDEF structure. The UHCRE thermal covers surface appears to have changed from specular to opaque (glossy white) with many black dots of various sizes that appear to be impact craters. An impact crater with a large area of discoloration is clearly visible in the upper right quadrant of the thermal cover. The dark discoloration is probably the results of an impact penetration of the 5 mil Teflon film allowing atomic oxygen to oxidize and erode the vapor deposited silver layer beneath. White dots of varying sizes can be seen on the cover, many appear to be encircling impact craters. The cover is not stretched as taut as in the flight photograph and locations of Velcro attach pads are not as prominent. The ground strap appears to be in place with no visible damage but appears to be a deeper copper color.

Thermal control was accomplished by attaching an aluminized Kapton thermal cover on the tray bottom (the Kapton facing the LDEF interior), placing the aluminum cylinder support structure on thermal isolators and covering the experiment with a thin (5 mil) silvered Teflon thermal cover. The silvered Teflon cover was supported by an aluminum frame, an integral part of the experiment structure, and held in place by Velcro pads selectively located on the frame and on the back of the cover. The copper colored strip extending over the trays upper flange is a copper coated pressure sensitive tape used to provide an electrical ground between the experiments thermal cover and the LDEF structure. The UHCRE thermal cover appears to be specular and intact with no apparent damage. The greenish colors on the left one third of the thermal cover are reflections from the surroundings. The ground strap appears to be in place with no visible damage but appears to be a deeper copper color than in the prelaunch photograph..

The silvered Teflon cover was supported by an aluminum frame, an integral part of the experiment structure, and held in place by Velcro pads selectively located on the frame and on the back of the cover. The copper colored strip extending over the trays lower flange is a copper coated pressure sensitive tape used to provide an electrical ground between the experiments thermal cover and the LDEF structure. The UHCRE thermal cover appears specular and intact with no apparent damage. A vertical strip of discoloration, approximately six inches wide and with a grain pattern, extends from top to bottom along the left side of the thermal cover. The cover appears less taut than in the flight photograph and locations of the Velcro attach pads are not as prominent. The ground strap appears to be in place with no visible damage, however, the color appears darked than in the prelaunch photograph.

The experiment tray flanges also appear to be discolored by the stain. The UHCRE detectors were contained in 16 peripheral LDEF trays with at least one UHCRE tray located on each row of the LDEF except row 3, row 9 and row 12. Each tray contains three cylindrical aluminum pressure vessels with an integral aluminum support structure. Each cylinder is filled with an Eccofoam insert that houses 4 UHCRE detector stacks. Each stack consist of layers of Lexan polycarbonate sheets (approximately 70) interleaved with several thin sheets of lead. Forty-seven of the 48 pressure vessels were pressurized to 1.0 bar of a dry gas mixture (oxygen, nitrogen and helium) and sealed.

The UHCRE thermal cover appears to be intact with no apparent damage but is stretched more taut than in the prelaunch photograph. The glossy blue-black appearance of the thermal cover in this photograph is apparently due to lighting conditions and not a change in the material optical properties. A vertical strip of discoloration, approximately six inches wide and with a grain pattern, extends from top to bottom along the right edge of the thermal cover. The oblong indentations in the thermal cover are in areas where Velcro pads are bonded to the backside of the cover. The irregular shaped discolorations on the cover surface appear to from lighting and reflections. The several white dots and the circular indents in the right center of the cover may be impact locations. The ground strap appears to be in place with no visible damage.

This photograph of the QuartzCrystal Oscillator experiment, upper left corner, shows the effects of the space environment. The white paint has turned brown due to interaction of the LDEF generated outgassing and contamination products with the space environment.

The on-orbit photograph of the experiment, upper right corner, shows the paint stripes that were orginally white are now a brown or tan color. The brownish tint can also be seen on the fasteners, the resonator shields and the resonator holddown cages. These coloration changes are thought to be a caused by interaction of the LDEF generated outgassing and contamination products with the space environment. The scratches and abraisions on the aluminum mounting plate, that occurred during the fabrication and cleaning process, are more visible than in either the pre-flight or postflight D02 integrated tray photographs. The difference observed is probably due to the variation of exposure and intensity of the light source.

Although not noticable in the photograph, a light coating of contamination was seen on all experiment surfaces in this location. The difference in colors of the IDE detectors, located on the right hand mounting plate, is a result of the reflected surroundings and not related to space exposure. A close observation of the detector surfaces reveal that some damage has occured from meteroid and/or debris impacts. One impact crater can be seen, upper right quadrant, on the detector located in the sixth (6th) row down from the top and the fifth (5th) row from the right. Other impacts, smaller in size, show as small white dots on the detector surface. The solar sensor seems to have changed little, if any. However, the color of the solar array baseplate, showing indications of contamination, appears to be darker than the detector mounting plate. The center section cover plate shows little change when compared with the pre-launch photograph. However, during inspection, a light coat of the brown contamination has been observed on all surfaces. The color of the bonding material (RTV) used to secure several thin specimen, sapphire, to individual mounting plates has changed from pink to gold. At one location, that of a single specimen, the bonding material is more gray than gold in color. This has been attributed to the specimen being considerably thicker. The EPDS thermal cover in the right hand side of the tray shows a light coating of brown contamination on the Chemglaze II A-276 white paint.

The tray has three (3) mounting/cover plates elevated on fiberglass stand-offs to provide clearance and protection for hardware and electronics located underneath. The stand-offs also raise the plates to a level that minimizes shading of detectors by the tray sidewalls. The mounting plate located at the left hand end of the tray is populated with eighty (80) metaloxide-silicon (MOS) capacitor-type impact sensors and one (1) solar sensor that is located approximately in the center of the mounting plate. The IDE sensors are two (2) inch diameter MOS capacitor structures approximately 250 um thick. The detectors are formed by growing either 0.4um or 1.0um thick silicon oxide, SiO2, layer on the 250um thick, B-doped polished silicon wafer. The top metal contact, the visible surface, was formed by vapor deposition of 1000A of aluminum on the SiO2 surface. Aluminum was also vapor deposited on the backside to form the contact with the silicon substrate. Gold wires are bonded to the front and back aluminum layers for use in connecting the detectors to the circuits. The complete wafers, IDE detectors, are mounted on chromic anodized aluminum frames by bonding the detector backside to the aluminum frame with a space qualified RTV silicon adhesive, de-volatized RTV-511. The difference in colors of the detectors is caused by reflections in the metallized surfaces. A reflection of one of the technicians is visible in the three (3) rows of detector on the left hand side of the mounting plate. The solar sensor, located at the mounting plate center, consist of four (4) silicon solar cells connected in series and associated circuity bonded to an aluminum baseplate. The solar sensor registered each orbital sunrise independant of LDEF orientation at the time of sunrise. When IDE solar sensor data from the six (6) orthogonal faces of the LDEF was correlated, the Interplanetary Dust Experiment clock could be precisely calibrated. The center 1/3rd tray cover is a chromic anodized aluminum plate that protects the IDE data conditioning and control electronics mounted underneath. The cover plate also serves as a mounting platform for ten (10) individual specimen holders provided by one of the IDE investigators.The material specimen, consisting of germanium, sapphire and zinc sulfide of different sizes, shapes and colors, are bonded to the specimen holders with an RTV adhesive. The specimen holders are attached to the cover plate with stainless steel non-magnetic fasteners. The 1/3rd tray cover plate in the right hand end of the experiment tray is an aluminum plate painted white with Chemglaze II A-276 paint and used as a thermal cover for the Experiment Power and Data System (EPDS). The EPDS is a system provided by the LDEF Project Office that processes and stores, on magnetic tape, the orbital experiment and housekeeping data from six (6) experiment locations on the LDEF.

During the mission, the tray surface was at an angle of approximately eighty-two (82) degrees to the orbital velocity vector and therefore exposed to a higher atomic oxygen flux than if it had been parallel with the velocity vector. Note the difference in color of the paint dots on tray clampblocks; white dots along the top edge, a light tan color on the center dot and a dark brown stain on the dots along the bottom of the photograph. The dots near the top of the photograph are adjacent to experiment location D07 and are exposed to a higher atomic oxygen flux than those adjacent to experiment location D05. Impacts of atomic oxygen with a surface tends to scrub away contamination from the that surface and leave it a much cleaner. The IDE experiment, located in the left side of the tray, seems to be coated with a thin coat of the brown contamination stain. The stain varies in color from a light tan at the top of the experiment to a darker color at the lower edge of the experiment baseplate. Darker smudges of the stain can be seen on the solar sensor baseplate where the solar cells have been bonded in place. The changes in colors seen in the detector surfaces, when compared to the prelaunch photograph, is due to the surroundings that are being reflected. The reflections seen in the flight photograph are from the sky in the lower rows of detectors and the orbiter's cargo bay liner in the upper rows of detectors.

The experiment's damaged multi-layer ther mal insulation blankets were removed from the experiment to accommodate experiment tray cover installation prior to operations that removed the experiment from the LDEF. The postflight photograph of the Heavy Ions in Space Experiment shows the four (4) experiment modules with the multi-layer thermal blankets severely degraded. The paint on the the thermal blankets top layer, previously white, is now a glossy tan or soft brown color. This change in color, from white to tan, was seen on other LDEF experiment surfaces that were coated with the same paint. The tape used to attach the thermal blanket to the module frames, 3M Y966 with a silvered Teflon film backing, failed during flight. The tape failed in tension across the width of the tape leaving portions of the tape on both the frame and the top layer of the thermal blanket. The tape failure is attributed to shrinkage of the thermal blanket which caused a significant buildup in tension across the taped joint. Detachment of the blankets along two (2) sides relieved the tension buildup and the blanket remained in place, although curled, during retrieval and post retrieval operations. The material exposed underneath the curled thermal blanket is the top sheet of the Lexan detector stack. The degraded multi-layer thermal blankets in each of the four modules show details of the blanket construction. The top layer of the thermal blanket is a 5 mil Kapton film with an aluminum coat ing vapor deposited on one side and with an exterior overcoat of Chemglaze II A-276 white paint on the other. The core or center section of the thermal blanket is constructed of approximately twenty two (22) layers of 1/4 mil perforated Mylar film with an aluminum coating vapor depos ited on each side. The bottom layer of the thermal blanket is also a 5 mil Kapton film with an alu minum coating vapor deposited on one side. The aluminum coated side of the Kapton film faces the adjacent Lexan detector stack sheet. A Dacron mesh (bridal veil) separator, clearly visible in the upper right module, is placed between each aluminized Mylar layer of the core material and also between the core material and the alu minized Kapton film used for the top and bottom covers. Insertion of the Dacron mesh between the aluminized layers minimizes heat leaks within the thermal blanket. A close observation of the exposed edges of the Multi-layer blankets shows the vapor deposited aluminum coating has delaminated from from the Mylar film and the Mylar film has eroded. The delaminated aluminum can be seen extending from the blanket material in the lower right module. Small pieces of aluminum have been observed adhered to surfaces of the LDEF, to the surfaces of some LDEF experiments and in the orbiter cargo bay during post-flight inspections. Also note the loss of portions of the Dacron mesh material. The loss of the Dacron material and some of the alu minum delamination is thought to have occurred prior to retrieval, however, a significant portion of the aluminum delamination from the Mylar is thought to have occurred post-landing due to the velocity and direction of air from the cargo bay purge system.

A light tan stain can be seen on the LDEF end structure along the left edge of the experiment tray flange. Lighter stains are also visible on the tray flange between the top and the center tray clamp blocks on that side. The photograph shows four (4) experiment modules mounted in the LDEF provided end center experiment tray. An experiment module consist of the thermal cover, a top stack of Lexan sheets for detecting low-energy ions, a honeycomb pressure cover and the main stack of CR-39 used to detect cosmic rays mounted in an aluminum housing. The four modules are identical in materials and construction. The exposed surface of each module is a white paint overcoat, Chemglaze II A 276, that has been applied to the top layer, aluminized Kapton, of a multi-layer thermal blanket. The frame around each of the four modules, a Z shaped aluminum structure, is covered with a sil verized Teflon film secured with 3M Y966 acrylic transfer tape. The 3M Y966 transfer tape on a siliverized Teflon film is also used to attach the four edges of the multi-layer thermal blankets to the modules frame. The combination of the silverized Teflon and the white paint provides the appropriate optical properities needed to meet experiment thermal requirements. The multi-layer thermal insulation blanket has extensive damage. The tape joints have failed along two (2) sides of each experiment module and have allowed the multi-layer insulation blan ket to curled back over its self.

The photograph shows extensive damage to the multi-layer thermal insulation blanket. The tape joints appear to have failed along two (2) sides of each experiment module and allowed the multi layer thermal insulation blanket to curled back over its self. The golden colored surfaces that have been exposed are the top sheet of the experiment's Lexan detector stacks that are held securely in place by the Z shaped aluminum structure. A light tan stain can be seen on the LDEF end structure along the upper edge of the experiment tray flange. Lighter stains that appear to be finger prints are also visible on the trays top flange. The paint on the top layer of the thermal blankets, origi nally white, now appears brown or light tan. The fragments of aluminum in the lower two quad rants appear to be the results of delamination of the vapor deposited aluminum from the thin aluminized Mylar thermal film.

The photograph shows four (4) experiment modules mounted in the LDEF provided end center experiment tray. An experiment module consist of the thermal cover, a top stack of Lexan sheets for detecting low-energy ions, a honeycomb pressure cover and the main stack of CR-39 used to detect cosmic rays mounted in an aluminum housing. Three modules are identical while the fourth module has been divided into four smaller units that allows the use of pressure covers with a lower energy threshold to Ion penetration. The exposed surface of each module is a white paint overcoat, Chemglaze II A-276, that has been applied to the top layer, aluminized kapton, of a multilayer thermal blanket. The frame around each of the four modules, a Z shaped aluminum structure, is covered with a silverized Teflon film secured with 3M Y966 acrylic transfer tape. The 3M Y966 tape on a silverized Teflon film is also used to attach the multi-layer thermal insulation blankets to the modules frame. The combination of the silverized Teflon and the white paint provides the appropriate optical properities needed to meet experiment thermal requirements.

The experiment's damaged multi-layer thermal insulation blankets were removed from the exper- iment, so the experiment tray cover could be installed, prior to removing the experiment from the LDEF The Postflight photograph shows the four (4) experiment modules with multilayer thermal blankets that are severely degraded. Paint on the top layer, previously white, is now a glossy soft brown or tan color. The thermal blankets apparently shrunk in flight causing them to detach from the modules frame along two sides, thereby relieving the tension buildup. The tape used to attach the blanket to the structure failed in tension across the width of the tape leaving portions of the tape on both the frame and the top layer of the thermal blanket. The thermal blankets on the three (3) large modules have curled to expose the top Lexan layer of the detector stack beneath. The curled thermal blankets that protected the four (4) smaller modules now exposes the 5 mil aluminized Kapton pressure covers beneath. The damaged thermal blankets shown in the two (2) tray quadrants on the right side of the photograph reveal representative cross sections of the multilayer thermal blankets. The thermal blankets top layer is a 5 mil aluminized Kapton film with an exterior overcoat of Chemglaze II A-276 white paint. The blanket core, center section of the blanket, is constructed of approximately twenty two (22) layers of 1/4 mil perforated Mylar film with aluminum vapor deposited on each side. A Dacron mesh separator, clearly seen in the lower right quadrant, is placed between each aluminized Mylar layer of the core material and also between the core material and the aluminized Kapton film used for the thermal blanket top and bottom covers. Insertion of the Dacron mesh between the aluminized layers minimizes heat leaks within the thermal blanket.

The photograph shows the extensive damage to the experiment's multi-layer thermal blankets that occurred during the LDEF mission. It appears that siliverized Teflon tape backed with an acrylic transfer tape that was used to attach the thermal blankets to the structure failed in tension. When the bond joint released along two (2) sides, the tension was relieved and the remaining tape continued to hold the blanket to the structure through out the rest mission. The outside blanket surfaces that were originally painted white are now coated with a glossy dark brown stain. The golden colored material in the three (3) full modules are the top sheets of lexan detector stacks held in place by the aluminum Z shaped structure. The deep rich redish-brown colored sections visible in one half (1/2) of the upper left module is also the top layer of detector sheets underneath support straps. In the two lower quadrants, the aluminum coatings that were vapor deposited on thin Mylar sheets of thermal blanket material appear to be starting to delaminate from the Mylar. A light coating of brown stain can be seen on the trays right flange. The stain appears heavier in the vicinity of nutplates used to attach the protective tray cover.Smudge marks that appear to be fingerprints can be seen along the edge of the thermal panel to the right of the experiment tray.

The aluminum housing, coated with alodine 1200, provides a container and structural support for the detector stack and a thermal interface with the LDEF structure. Nonmagnetic stainless steel fasteners are used for the experiment assembly and for attaching the experiment adapter plate to the tray structure. Note reflections from the surroundings and ripples on the Kapton cover. The experiment appears to be intact with no apparent physical damage from the extended space exposure. The ripples in the Kapton cover foil observed in the prelaunch photograph also appear in the flight photographs but at a lower frequency of repetition. The source of discolorations on the aluminized Kapton cover, that appear to be horizontal scratches, is unknown. The discolorations were observed in the flight photograph but were seen as vertical scratches, not horizontal scratches. The dark shadowing on the left half of the experiment Kapton cover appears to be a reflection of support equipment.

The environmental exposure was similar with one significant exception, the trailing edge location was not exposed to continuous bombardment by the relativity high atomic oxygen flux. The originally white paint dots on the clamp block located in the center of the trays right flange and on the clamp blocks at each end of the left flange appear to be off-white. The experiment tray in the D09, leading edge, location is divided into six sections. One of the six sections, upper right corner, provides space for one of three Trapped Proton Energy Spectrum Determination Experiment, M0002-01, modules. The other five sections of the tray contain M0003 sub-experiments consisting of coatings, thermal paints, polymers, glasses, composites, solar power components, semi-conductors and detectors that provide various environmental data. The experiment, overall, appears in good condition. The experiments located in the upper left and center left sections are heavily coated with debris particles from other degraded experiments. Experiments in three of the five sections appear to have survived the mission intact with minor physical damage. Experiments in the other two sections have sustained damage to thin metallized and/or coated polymer samples. The material samples located in upper left section of the tray consist of a composite plate with two quadrants painted white, one quadrant painted black and one quadrant remaining bare. The experiment remains intact with the only apparent change being the color of the bare composite. The samples in the center left and the center right tray sections remain intact but appear sharper and brighter due to the excess blue in the photo. In the center left section, the plate securing the three rectangular samples along the right edge appears to have changed from dark brown to a light tan color. Along the left side the two horizontal rectangular aluminum mounting brackets appear gold in color and the square sample mount in the upper left corner has changed from dark brown to a light tan. Two thin film solar cells are missing and the cell mountings appear to have changed colors. The experiment in the center right section appears to be intact with only a few samples changing colors. The two white circular samples were bright yellow and the two light tan square mounts to the right of the four off-white squares were dark brown in the prelaunch photograph. The experiment in the lower left section of the tray consist of three metallized polymer and one coated polymer samples.The test sample in the upper left corner, a grid of metallic foil squares on a Kapton sheet, is essentially gone. The sample in the upper right, a metallized Kapton sheet, appears to be intact with only a few spots where the foil is missing. The sample in the lower left corner, a Kapton sheet imprinted with a pattern of metallic foil tripoles, is severely degraded and remains attached in only a few spots. The test sample in the lower right corner, Kapton sheet with a white paint overcoat, appears to be intact only a change in color from white to a light gray. The other two samples, upper right and lower left corners, are severely degraded. The metallized and coated polymers located in the lower right tray section appear to have survived the exposure intact but are discolored. Approximately half of the thin film polymers in the upper right corner of the section are loose at one end but remain attached. The silver Teflon cover, the large rectangular shape near the center of the section, appears to remain intact but has changed to a milky white color. Thermal control coatings, mounted along the left side of the section, are discolored as are the exposed surfaces of the sample holders.

The color of the white paint dot on the center clamp block of the experiment tray lower flange appears to be unchanged. The Space Environment Effects on Fiber Optic Systems Experiment occupies a six (6) inch deep LDEF peripheral tray and consist of an aluminum internal support structure, an Electronic Power and Data System (EPDS), three aluminum experiment mounting plates, two aluminum cover plates, four operational digital optical data links (lengths of 48 m, 45 m and two 20 m) exposed to the space environment, three passive cabled fiber optic links (each 10 m long) with electronic components and end connectors, aluminum brackets and non-magnet stainless steel fasteners required to assemble the experiment. Four active cabled optical fiber links (one black, one blue, one yellow and one light tan), each configured in the form of a planar, helix coil, are attached to thermally isolated mounting plates with black anodized aluminum clips cushioned with silicone-rubber spacers. The three mounting plates are coated with a Catalac off-white thermal control paint, the large cover plate is coated with Chemglaze II A-276 white paint and the smaller cover plate is coated with IITRI S13G-LO white paint to meet thermal control requirements. The three passive cabled optical fiber links and all emitters, detectors and associated electronics are located in the interior volume of the tray. All cabled optical fibers terminate in connectors mounted in brackets that are located in the tray bottom or on the backside of the thermally isolated mounting plates. The Space Environment Effects on Fiber Optic Systems Experiment appears to be intact with no apparent structural damage. Colors of all three exposed coils of fiber optic cables have changed significantly. The cable located in the lower right corner, originally glossy black, appears to be dark brown and the cable in the lower left position, originally a glossy royal blue, now appears to be a navy blue color. The two 20 m coils of fiber optics links appear to have more extensive color changes. The originally yellow cable, that appeared slate gray in the flight photograph, now appears a light gray and the brown cable in the flight photograph appears to be a lighter brown. Details of the discoloration above the light gray coiled link, observed in the flight photograph, can be seen. The color of the silicone-rubber spacers under the coil attach clips have changed from clear to brown and appear to have discolored the light gray cable link. Brown discolorations appear on the left edge of the large cover plate and on the tray structure in the vertical clearance (top, center and bottom) between the mounting plates The Chemglaze white paint on the large cover plate appears to have maintained the prelaunch color but the IITRI S13G-LO white paint on the small cover plate appears to have changed to a uniform light tan color. Spots on the large cover plate that appeared to be impact craters in the flight photograph can be seen on the white paint in the lower left corner of the plate. Other craters, not readily visible in the flight photograph, can also be seen.
