'''AS-103''' was the third orbital flight test of a [[Boilerplate (spaceflight)|boilerplate]] [[Apollo spacecraft]], and the first flight of a [[Pegasus (satellite)|Pegasus micrometeoroid detection satellite]]. Also known as ''SA-9'', it was the third operational launch of a two-stage [[Saturn I]] launch vehicle.
