For as long as mankind has possessed a sense of wonder, astronomy
has been practised in one form or another. It can be thought of as
having graduated to the status of a true science at the point in
history when it became forever separated from astrology. Clearly
they were not of the same mould; astronomy was hard to do;
astrology was merely hard to swallow. The next significant change
came in the early 20th century. Men and women of science felt it
was no longer sufficient to simply catalogue the visual
characteristics of the stars and other heavenly bodies; the desire
to understand their physical makeup, behaviour and creation gave us
the study of astrophysics. As the name suggests, this is the
physics of astronomical bodies and the space they inhabit. During
the second half of the 20th century interest turned also to the
other eight planets of our solar system, spawning several new
disciplines relating to Planetology, the formation of the solar
system, and the possibility of past or present extraterrestrial
life. Every decade of the last century brought ever more numerous
and fascinating discoveries. It was not until 1930 that Pluto, the
ninth planet, was discovered.;Only as late as 1978 was it
discovered that Pluto possessed a moon. And now, in late 2005,
NASA's Hubble Space Telescope has given astronomers evidence that
Pluto may have not one, but three moons. In recent decades much
interest has also been given to the far reaches of the universe --
far stars; other galaxies, some old, some still forming; and even
the earliest detectable galaxies of the universe, at the very
limits of our ability to probe. Each field of space study requires
its own special tools and its own expertise. The many programs that
come loosely under the headings of astronomy and space exploration
are as varied and rewarding as the fascinating discoveries that
they have made. To the uninformed, the exploration of deep space
may seem esoteric and unexciting, but in truth the wonder and the
beauty of deep space outshine almost anything that Earth and man
can offer. The time when people can go and explore deep space in
person is still well into the future. Until then, we shall continue
to do as we have done for the past 40 years, sending unmanned
spacecraft and satellites as our proxies and ambassadors to the
universe.;This book examines deep space exploration missions, past,
present and future, and their results.
