... I can’t remember the number, was supposed to deploy the Long Duration Exposure Facility LDEF , and so somewhere in there they shifted the timing of the TDRS flights, and our crew then became the LDEF retrieve crew. Then we said, “Okay. Hey, now, this is okay.” So we started training ... planning or training for were contingency EVAs; there was nothing planned. Flying up to the LDEF and retrieving it was starting to look like a pretty nice mission because of the ...

... were from France, 2 from England, and 1 from Canada. R&D value, compatibility with LDEF and other experiments, and effort cost had been selection criteria. Technical areas included materials, thermal-control coatings, detectors, power, micrometeoroids, electronics, lubrication, optics, and space-debris detection. Eighty percent of LDEF's experiment trays had been filled; the remaining space would contain micrometeoroid-detection panels ...

... standards for assessing performance of new solar cells. The space power experiment (SPEX) on the LDEF would evaluate the use of commercially available components for a space-power system. With three LDEF trays carrying commercially available terrestrial solar cells and a fourth carrying commercial power electronics and ... future space-power systems. In the ion-beam texturing and surface-coating experiment on the LDEF, which would expose such surface samples to launch stress and near-earth space, ground tests ...

We did ... a satellite—I guess it was managed out of Langley Research Center, Hampton, Virginia —called LDEF, which stands for Long Duration Exposure Facility. This was basically to test optical surfaces and ... by now were essentially a team, and we proposed an experiment that flew on LDEF. But LDEF had problems. Rather than staying in space for nine months, it stayed sixty-nine months ...
