Template:Infobox spaceflight. NASA's Long Duration Exposure Facility, or LDEF (acronym pronounced "EL-deaf"), was a school bus-sized cylindrical facility designed to provide long-term experimental data on the outer space environment and its effects on space systems, materials, operations and selected spore's survival. It was placed in low Earth orbit by Space Shuttle . LDEF's 69 months in space provided scientific data on the long-termeffects ofspace exposure on materials, components and systems thathas benefited NASA spacecraft designers to this day. There were a total of80 testtrays on LDEF. LDEF had 12 sides and 2 end caps to hold testtrays/experiments. It was approximately KM up in orbit. / /,2J N LONG DURATION EXPOSURE FACILITY (LDEF) ARCHIVE SYSTEM Brenda K. Wilson Boeing Aerospace Operations, Inc. N.

Investigation of the interplanetary dust cloud is characterized by contributions from quite different methods and fields, such as research on zodiacal light, meteors, micrometeoroids, asteroids, and comets. Since the earth's environment and interplanetary space . THE fullerenes C60 (ref. 1) and C70 have been found to occur natu-rally on Earth2,3, and have also been invoked to explain features in the absorption spectra of interstellar clouds1,4. But no.

Impact residue analysis is inherently a difficult task, as a particle traveling at speeds of between 5 and 70 km s-1 leaves little chemical evidence following a hypervelocity collision. Notwithstanding this difficulty, returned surfaces from a range of spacecraft, including the Long Duration Exposure Facility (LDEF), the Space Flyer Unit (SFU), the. the early s, including 57 experiments on the Long Duration Exposure Facility (LDEF), which was retrieved in after spending 69 months in LEO (de Groh et al., ). The ISS provides an ideal platform for long‑term space environment effects testing, particularly as experiments can be returned to Earth for postflight analyses.
