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…
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:…
Spacecraft computer program development improvements to be utilized by MIT
Just for the record, I would like to record a list of program development improvement ideas which MIT plans to incorporate. This list was gleaned from discussions by Ed Copps, Fred Martin and Alex Kosmala during the week of October 2, 1967….
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…
Computer program requirements for AAP
On April 20 we had a meeting to assemble preliminary spacecraft computer program requirements for AAP missions 1 through 4. This is one step in the process of assembling a program requirements document needed to provide a basis for sensible contract negotiations with MIT and to provide a basis upon which MIT may proceed with…
LMSS RTCC program test documentation needed
This may be a waste of time what with the LMSS on its way down the tubes, but during that review of the RTCC computer programs a few weeks ago it was obvious that the contractor has no intention of providing any test specification or test results documentation. In fact, I am pretty sure their…
LGC computer requirements to provide DPS backup of SPS
During our discussion at MIT last week, the question came up as to whether it is necessary to have trajectory integration techniques in the LCG for the trans-earth phase of the mission as well as the lunar phase. The argument is that if we are serious about using the LM descent propulsion system to back…
