A serious misunderstanding between MIT and Grumman resulted in a situation which would have been catastrophic to the AS-206 mission if it had not been discovered. Specifically, the direction the LM descent engine gimbals move when commanded by the spacecraft computer was opposite to the way they were supposed to. Upon discovery of this, Grumman…
LGC program development for AS-278B
This note is intended to document my understanding of the situation with regard to the spacecraft computer programs for the alternate AS-278 mission. In particular, I would like to record how we are responding to the current programming needs in this area….
AS-206 LGC program status
On October 6th at MIT, we held a review of the AS-206 computer program which they have romantically christened “Sunburst”. Our primary objectives were twofold; first, to make certain that the formulation of the program was consistent with the way we intend to fly the mission, and second, to determine the current status of the…
We’ve bit the bullet on GRR
The fact that the 206 LM is the only LM to be powered up when launched presents a requirement for some unique manner for the G&N to detect or at least be informed that liftoff has occurred. In the absence of a hardwire liftoff signal, it had been intended to transmit a guidance reference release…
In which some items of interest regarding the AS-206 LGC program status are discussed
Quite a number of things have been going on with regard to AS-206 mission plans, spacecraft configuration, and the LGC computer program development. I would like to take a couple of minutes here to let you know about the latest developments in the latter….
More interesting things about our work with MIT
I always start out these MIT newsletters with the hope they will be short enough that you’ll be willing to read ’em. A couple of things came up at our Program Development Plan review on November 16 there that I thought I would pass on….
Latest on the AS-206 spacecraft computer program
During the January 11 program development plan meeting at MIT, a couple of things came up regarding the AS-206 program that are probably worth recording here….
In which is described the Apollo spacecraft computer programs currently being developed
It is possible to take advantage of the stretchout of the Apollo flight schedule in the manner in which we develop the spacecraft computer programs at MIT. Although the flight schedules have not been fixed, it is evident that certain things can be done which will not only improve the quality and capability of the…
Ground rules for MIT man loading for AGC programming
This is really for my own records, but in case you are interested, we presented the following ground rules to MIT with Bill Kelly’s (ASPO’s MIT Contractual Officer) concurrence. These ground rules were to cover the work they are doing in revising their man loading estimates for contract negotiations which are coming um in the…
Another Apollo spacecraft computer program status report
This is another of my gripping reports on the status of the Apollo spacecraft computer programs and associated matters based on my weekly visit to MIT on June 28 and 29….
