MIT’s digital computer facilities are still a problem
On April 12 at MIT we spent almost the whole morning discussing justification for and status of the IBM 360/75 computer installation they use for spacecraft computer program development. As of today, we haven’t really resolved the issue of whether or not we should retain that computer at MIT. On the other hand, I think…

This memo is to inform you of things that happened at the June 25 ASCCB meeting. Some were quite significant….
Some things about the Descent Propulsion system as controlled by the LGC
I guess I would have realized this if I had thought about it, but it was a surprise to me (and others) to learn that the Descent Propulsion System (DPS) engine in the LM is not aligned through the cg prior to ignition. I suppose I had assumed that it would be handled the same…

Inflight alignment of the COAS

North-American Rockwell (NR) participation in Mission Techniques Activity
This note is to let you know that NR participation in the Mission Techniques activity is almost negligible. (Except reentry – Bobby Johnson’s team working on the EMS is outstanding.)…
