FOREWORD
The success of the Skylab mission and its
Apollo Telescope Mount (ATM) has been a thrilling event to those of us who have
been engaged with NASA since 1958 in planning and consummating solar research
missions in space. Conceived in 1965 as a relatively simple exercise to test
man's capability for doing useful work in space, the ATM concept was subjected
to a continuous process of critical review, revision, and upgrading by NASA,
working in concert with industry and the scientific community. The ATM that
finally emerged became one of the most important milestones in the history of
solar astrophysics. The mission in fact represented the final step in the
initial long-term strategy for solar astrophysics that was set by the Space
Science Board of the National Academy of Sciences in 1960, which called for the
installation in space of a very large orbiting solar observatory, weighing
several thousand megagrams and comparing favorably with ground-based
observatories as regards light gathering power and angular and spectroscopic
resolution.
In terms of versatility, sensitivity, and
reliability, the performance of the ATM telescopes and instruments exceeded the
highest aspirations of astronomers during the 1960's. Yet, the mission appeared
headed for total and complete disaster, until rescued by the heroic and
skillful exploits of the astronauts in repairing the damage incurred by the
spacecraft during launch. In this and other ways, the role of man in the
operation of space observatories was clearly, even brilliantly, delineated.
The study of ATM observations has already led
to many new discoveries about the nature of the Sun and about the fascinating
events that occur on even a very ordinary star. Especially illuminating has
been the recognition of the extent to which the Sun's magnetic field is
responsible for the structure, dynamics, and heating of the Sun's outer layers.
So massive was the harvest of information, however, that it will be many years
before the possibilities for productive analyses are exhausted. I am confident
that well before that time we shall have gained such entirely new perspectives
on the Sun that we will be confronting a brand new set of questions and
addressing them with a second generation of solar space experiments.
