'''AS-105''' was the fifth and final [[orbit]]al flight of a [[boilerplate (spacecraft)|boilerplate]] [[Apollo spacecraft]], and the third and final launch of a [[Pegasus (satellite)|Pegasus micrometeoroid detection satellite]]. It was launched by '''SA-10''', the tenth and final [[Saturn I]] rocket, in 1965.

== Overview ==
AS-105 was an [[Project Apollo|Apollo]] [[Boilerplate (spaceflight)|boilerplate]] spacecraft; boilerplate BP-9A was used for the flight. The spacecraft reentered on November 22, 1975.<ref>{{cite web | url=http://www.astronautix.com/lvs/saturni.htm | title=Saturn I | access-date=February 28, 2011 | publisher=Astronautix | url-status=dead | archive-url=https://web.archive.org/web/20101207080648/http://www.astronautix.com/lvs/saturni.htm | archive-date=December 7, 2010 }}</ref> The Saturn launch vehicle (SA-10) was similar to those of missions AS-103 and AS-104.  As on the previous mission, the boilerplate [[Apollo service module|service module]] was equipped with a test installation of a reaction control engine package.

The primary flight objective was to continue demonstration of the launch vehicle's iterative guidance mode and evaluation of system accuracy.

== Launch ==
AS-105 was launched from [[Cape Canaveral Air Force Station|Cape Kennedy]] Launch Complex 37B at 08:00 [[Eastern Standard Time|EST]] (13:00 [[GMT]]) on July 30, 1965, on the last Saturn I rocket, SA-10. A planned thirty-minute hold ensured that launch time coincided with the opening of the [[Pegasus (satellite)|Pegasus]] launch window. The launch was normal and the payload was inserted into orbit approximately 10.7 minutes after lift-off. The total mass placed in orbit, including the spacecraft, Pegasus spacecraft, adapter, instrument unit, and [[S-IV]] stage, was 34,438 pounds (15,621&nbsp;kg).

The spacecraft was separated 812 seconds after lift-off and the separation and ejection system operated as planned. The [[Pegasus 3]] spacecraft, which was attached to the S-IV stage of the Saturn I and stowed inside the boilerplate service module, was deployed 40 seconds after command initiation at 872 seconds. Pegasus 3 was a 1423.6&nbsp;kilogram (3138.6 pound) micrometeoroid detection satellite, which was bolted to the S-IV.
