TheAtlas-Ablewas an Americanexpendable launch systemderived from theSM-65 Atlasmissile. It was a member of theAtlas familyof rockets, and was used to launch severalPioneerspacecraft towards theMoon.Of the five Atlas-Able rockets built, two failed duringstatic firings,and the other three failed to reach orbit.[1]
The Atlas-Able was a three-and-a-half-stage rocket, with astage-and-a-halfAtlas missile as the first stage, anAblesecond stage, and anAltairthird stage.[2]
The first Atlas-Able used anAtlas Cas the first stage,[3]and was intended to carryPioneer P-1,but exploded during a static fire test on 24 September 1959.[4]
The remaining Pioneer launches usedAtlas Dmissiles. Launches were conducted from Launch Complexes12and14at theCape Canaveral Air Force Station.One launch was planned fromLaunch Complex 13;this became the second Atlas-Able to be destroyed during a static firing, and hence never launched.[1]
