From Wikipedia, the free encyclopedia
The Atlas I was an American expendable launch system, used in the 1990s to launch a variety of different satellites. The "I" in "Atlas I" can cause confusion, as all previous Atlas rockets were designated using letters, ending with the Atlas H, however subsequent rockets were designated using roman numerals, starting with the Atlas II. Officially, the "I" is considered to be is the roman numeral "1".
The first stage of the Atlas I is an Atlas H, and the second stage is a Centaur. The first stage has an MA-5 booster unit, consisting of two LR-89 engines, for stage-and-a-half staging (used in conjunction with the Centaur, this gives the Atlas I 2.5 stages).
