“D” Rendezvous Mission Techniques Ground Rules, Working Agreements, and other things
On June 14 we cranked up the “D” Rendezvous Mission Techniques activities again. It was a grueling profitable day. In fact, we had such a good time we’ve scheduled another one for July 12….
Attention worthy Descent Program Anomaly
Gene Kranz brought the attached G mission LUMINARY Anomaly Report to my attention. I have no idea how he happened to find it amongst all the more insignificant ones. No one else seemed particularly aware or concerned about it, but I wanted to bring it to your attention….
C’ Communication Loss
A lot of work is going into the subject contingency – with respect to:…
Rope manufacture for AS-502
This note is to inform everyone that the AS-502 spacecraft computer program ropes will be made precisely the same as those for AS-501. Specifically, it is MIT assembly Solarium 55. You recall Solarium 54 was our original AS-501 A-release, but it was necessary to make a modification in one of the rope modules to correct…
Data requirements during rendezvous sequence
The purpose of this memorandum is to establish a requirement for high bit rate (HBR) telemetry data during the mission “C” rendezvous sequence….
GDC required for TLI
In reference to your November 18 memo to me in which you state that the Gyro Display Coupler (GDC) is required to be operable for commitment to TLI, I would like to assure you that current C’ mission rules reflect this requirement. It is agreed by everyone I have talked to that redundant attitude reference…
Lunar orbit revolution counter for C’
This may seem like a trivial matter – however, before any confusion arises let’s firmly establish the means of identifying revolutions in lunar orbit by number. Specifically, unless there’s some good reason for choosing another way:…
MSFC/MSC OWS Computer Program Meeting
On January 15, 1970 we had a get-acquainted session for MSFC and MSC people who will be involved in the development and use of the Orbital Workshop (OWS) spacecraft computer program. Our basic objectives were:…
“D” mission launch window is nice
This note is in follow-up to our “D” mission launch window discussion during our Tuesday morning meeting. Essentially, the situation is as I understood it to be at that time. Real time procedures can be and are being established to provide a launch window about two and threequarters hours long by using the earlier propulsion…
