It is a combination of lists that have been prepared at Marshall Space Flight Center and Kennedy and Johnson Space Centers, places where intensive shuttle activities are being carried out. In the nature of acronyms--which are compressed identifiers of systems or structures felt to be too long and cumbersome to be spelled out in the normal fashion--the list is neither comprehensive nor totally up to date. This guide should be used in conjunction with the Government Printing Office Style Manual, following the GPO rules of capitalization, punctuation, spelling, etc. This list is intended as a guide or reference and should not be considered to have the status and sanction of a dictionary. The transience of technical acronyms is best demonstrated by contrasting this list with the special lingo and jargon employed during the days of Apollo. A limited number of terms are the same, but the working groups speak in a different dialect. Perhaps the best way to think of this collection is as a phrasebook to help observers make their way in comprehending parts of a brand-new world. °°. m SECTIONI GLOSSARY Atlas-Centaur Class Payloads weighing approximately 4,000 to A 4,400 pounds (1,800 to 2,000 kilograms).
