No extra memory for the Apollo Spacecraft Computer
- Date: Oct 4 1966
- From: FM/Deputy Chief, Mission Planning and Analysis Division
- Subject: No extra memory for the Apollo Spacecraft Computer
One of the most significant decisions coming out of the AS-278 computer
program review with the Apollo Spacecraft Program manager on September
15 and 16, was his absolute assurance that the spacecraft computer memory
would not be augmented for the AS-503 or AS-504 flights. Accordingly,
all program development should proceed on that basis for those flights.
On the other hand: I would hope and expect that work will continue on
the auxiliary memory for follow-on missions, and I feel we should offer
whatever assistance MIT can provide on a non-interference basis to that

AS-207/208 (also known as AS-278) was to have been the first test of the LM in Earth orbit. It was also to have be a dual mission with the command and lunar modules launched on separate Saturn 1Bs. The mission was cancelled after the Apollo 1 fire and the Saturn 1Bs were used to launch Skylab 3 (AS-207) on July 28, 1973 and Skylab 4 (AS-208) on November 16, 1978. The LM was first tested by Apollo 5 in January 1968.
Before the Apollo 1 fire, the mission referred to as AS-503 was an unmanned Earth orbit test flight of the LM and CM scheduled for October 1967. The launch vehicle, SA-503 was used for Apollo 8, December 23 1968.
Before the Apollo 1 fire, the mission referred to as AS-504 was originally scheduled for December 1967. AS-504 eventually launched as Apollo 9, March 3 1969.
