The timeliness of the retrieval was of critical importance, because a high rate of solar flux had increased the density of the LDEF`s orbital environment and accelerated its rate of orbital decay. Specialists who carefully monitored the stability of the craft`s orbit had anticipated that if the LDEF was not retrieved in time, it would pass too low for the shuttle to safely reach, and could be destroyed during re-entry in February 1990.
The crew performed a 41⁄2-hour photographic survey of the free-flying structure, which held 57 science, technology and applications experiments.
