Atlas-Agena A




Written and Edited by Cliff Lethbridge


Classification: Space Launch Vehicle

Length: 99 feet

Diameter: 10 feet


The Atlas-Agena A was a two-stage rocket using the Atlas D missile as a first stage and the Lockheed Agena A as a second stage.

The Agena family of second stages originated in the Atlas-Hustler concept proposed by the U.S. Air Force. Since the Agena A was designed to be tailor manufactured for each flight, it proved impractical and was never used by NASA.

The Agena A was 19 feet, 4 inches long and 4 feet, 11 inches wide. It employed a single-start Bell engine producing 15,200 pounds of thrust.

The Bell engine was manufactured in two models for the Agena A. The Model 8001 version burned JP-4 jet fuel while the Model 8048 version burned IRFNA/UDMH liquid fuel.

The total vehicle was capable of carrying a 5,000-pound payload to low-Earth orbit.
