system. Experience what it is like to look at our solar system
with ultraviolet eyes, infrared eyes, radio eyes, and radar
eyes.
It has been seven years since the first edition. The explo-
ration of space has continued at a rapid pace since then, and
many missions have flown in the interim. New discoveries
are being made all the time. This second edition will catch
you up on all that has happened since the first, including
several new chapters based on information from our latest
missions.
I invite you to enjoy a virtual exploration of the solar
system by flipping through the pages in this volume. This
book deserves a place in any academic setting and wherever
there is a need to understand the cosmos beyond our home
planet. It is the perfect solar system reference book, lavishly
illustrated and well written. The editors and authors have
done a magnificent job.
We live in a wonderful time of exploration and discovery.
Here is your window to the adventure.
