AS-101 (also designated SA-6) was the sixth flight of the Saturn I launch vehicle, which carried the first boilerplate Apollo spacecraft into low Earth orbit.

The spacecraft and its upper stage completed a total of 54 orbits before reentering the atmosphere and crashing in the Pacific Ocean on June 1, 1964.

The first five launches of the Saturn I had carried Jupiter nosecones, a proven design which allowed engineers to focus on development of the rocket.

The second attempt was scrubbed after the rocket's guidance system overheated due to failure of an air conditioning compressor.

The vehicle made a total of 54 orbits, re-entering the atmosphere east of Kanton Island in the Pacific Ocean on June 1.
