Preface
This report contains abstracts of papers presented at the "kick~off"
workshop for MSATI (Mars Surface and Atmosphere Through Time).
The workshop was sponsored by the Lunar and Planetary Institute (LPI),
the Laboratory for Atmospheric and Space Physics (LASP) at the Univer~
sity of Colorado, and the MSATI Study Group. It was hosted by LASP
and held on September 23-25, 1991, at the Conference area of the Coors
Events Center on the Boulder campus of the University of Colorado. Pro~
gram committee members were Bob Haberle, Bruce Jakosky, Ken Tanaka,
Ben Schuraytz, and Amos Banin. The workshop was convened by Bob
Haberle and Bruce Jakosky, and coordinated by Ben Schuraytz, with
assistance from the staff of the Program Services Department and Publica~
tions Services Department at the LPI.
The purpose of the workshop was to bring together the MSATI com~
munity and interested researchers to begin to explore the interdisciplinary
nature of, and to determine the relationships between, various aspects of
Mars science that involve the geological and chemical evolution of its sur~
face, the structure and dynamics of its atmosphere, interactions between
the surface and atmosphere, and the present and past states of its volatile
endowment and climate system. It was the intention of the workshop
organizers to involve a broad spectrum of Mars researchers in order to fos~
ter interdisciplinary collaborations. The format was chosen to allow maxi~
mum time for discussion and interaction. Over 100 people attended and
judged the workshop to be highly successful.
Plans are now being formulated to hold focused workshops that will
pursue in greater detail the various issues raised in Boulder. At the end of
the three~year study project, a final "wrap~up" workshop will be held that
will bring the community together once again to assess the accomplish~
ments of the program and to help increase the science return from the
Mars Observer.
