The Atlas-Able was an American expendable launch system derived from the SM-65 Atlas missile. It was a member of the Atlas family of rockets, and was used to launch several Pioneer spacecraft towards the Moon. Of the five Atlas-Able rockets built, two failed during static firings, and the other three failed to reach orbit.^[1]

The Atlas-Able was a three-and-a-half-stage rocket, with a stage-and-a-half Atlas missile as the first stage, an Able second stage, and an Altair third stage.^[2]

The first Atlas-Able used an Atlas C as the first stage,^[3] and was intended to carry Pioneer P-1, but exploded during a static fire test on 24 September 1959.^[4]

The remaining Pioneer launches used Atlas D missiles. Launches were conducted from Launch Complexes 12 and 14 at the Cape Canaveral Air Force Station. One launch was planned from Launch Complex 13; this became the second Atlas-Able to be destroyed during a static firing, and hence never launched.^[1]

Launches

Launches of Atlas-Able^[2]^[3]
Date	Serial No.	Mission	Launch site	Outcome
-	Atlas 9C	Pioneer P-1	LC-12	Failure. Explosion during a static fire test.^[5]
26 November 1959	Atlas 20D	Pioneer P-3	LC-14	Failure. The Payload fairing broke up at 45 seconds after liftoff, causing loss of the upper stage and payload.^[6]^: 24
25 September 1960	Atlas 80D	Pioneer P-30	LC-12	Failure.^[7] A propellant feed on the second stage had a malfunction.^[6]^: 26
15 December 1960	Atlas 91D	Pioneer P-31	LC-12	Failure.^[8] Vibration and/or debris from the Able adapter section ruptured the liquid oxygen tank of Atlas, causing an explosion.
