The history of the Space Department has been well chronicled, and much of that inprevious issues of this publication. For this anniversary issue, we set out to identify andemphasize the major thrusts that are important to the Department, that have evolvedthrough our past to the present, and that will continue into the future. It is our hopethat this issue captures this purpose with due respect to the accomplishments of theearly days, but emphasizing the Space Department as it is today.
