Foreword
On July 20, 1989, President George Bush charted a new course for human exploration of
space:
"... a long-range continuing commitment. First, for the coming decade -
for the 1990's ~ Space Station Freedom, our next critical step in all our
space endeavors. And for the next century, back to the moon, back to the
future, and this time, back to stay; then a journey into tomorrow, a journey
to another planet - a manned mission to Mars. Each mission should and
will lay the groundwork for the next."
The Long Duration Exposure Facility (LDEF) is providing critical technology for future
spacecraft, including Space Station Freedom, and thus plays a major role in the
President's vision of human exploration of space.
LDEF was carried into orbit in April 1984 by the Space Shuttle Challenger. The 11-ton
satellite contained 57 experiments to assess the effects of the space environment, i.e.,
ionizing radiation, meteoroids, cosmic dust, and high altitude atomic oxygen on materials
and mechanical, electronic, optical, and living systems. In January 1990, after 69 months
in low Earth orbit, LDEF was retrieved by the Space Shuttle Columbia and returned to
Earth. The retrieval occurred 57 months after it was originally planned, due in part to
the Challenger tragedy. The 69 months in space provided experimenters the unique
opportunity to sample and measure the space environment over a longer time period than
originally planned.
The 57 LDEF experiments were returned to the Principal Investigators and their science
teams for analyses and interpretation. In June 1991, over 400 LDEF researchers and
data users met in Kissimmee, Florida for the First LDEF Post-Retrieval Symposium.
The papers presented contained important new information about space environments and
their impact on materials, systems, and biology. This publication contains the material
presented at the symposium, categorized by subject:
LDEF Mission and Induced Environments
Space Environments - Ionizing Radiation
Space Environments - Meteoroid and Debris
Space Environmental Effects - Materials
Space Environmental Effects - Systems
Space Environmental Effects - Biology
Space Environmental Effects - Microgravity
The Future
During the symposium Sally A. Little, NASA Headquarters, chaired the LDEF
Mission and Induced Environments session; William L. Quaide, NASA Heaquarters,
iii
chaired the Space Environments - Meteoroid and Debris session; Thomas W.
Crooker, NASA Headquarters, and Bland A. Stein, NASA Langley Research Center, co-
chaired the Space Environmental Effects - Materials session; Judith H. Ambrus,
NASA Headquarters, and P. Rex Miller, W.J. Schaefer and Associates co-chaired the
Space Environmental Effects - Systems session; and James L. Jones, NASA
Langley Research Center chaired the session called Others.
Some presentations in these documents underwent a title change; others were combined
with two or three presentations; two were not presented orally. However, all oral
presentations are represented in written form. Where full-length papers were
unavailable, the abstracts have been reprinted. All papers were reviewed for technical
content as well as form.
We wish to thank the contributors, as well as the reviewers of these papers. We also wish
to thank Dr. William H. Kinard, without whose vision and persistence, there would not be
an LDEF project or the valuable data it has collected.
The LDEF Science Office plans to organize and conduct two additional symposia, one in
San Diego in June 1992 and another in 1993. The proceedings from these two symposia
will be published as NASA Conference Publications.
We believe that the LDEF data reported in this three-part document will make important
contributions to charting the new course for the exploration of space.
