Pete Conrad has discovered and, if necessary, intends to do something that Dan Payne and others around here got squared away a year or more ago. Unfortunately, due to the press of more urgent business, we failed to advertise it enough. This note is to make sure you know that the AGS does a better…

Recommendation to retain the Two-Stage Lunar Orbit Insertion (LOI) Maneuver
This memorandum documents the results of our review of the two-stage LOI maneuver which you requested as a result of a recent OMSF suggestion that it might be preferable to return to a single burn plan. Participation in this review involved all operational elements of MSC concerned in this matter. The conclusions are unanimous….
CSM Rescue Mission Techniques are complete and clean
On June 9 we had our final Mission Techniques meeting on CSM Rescue. I am pleased to report that this stuff appears to be in very good shape. After much hard work by many people, the CSM rescue rendezvous plans shake down to only two basic profiles. Each of these has minor modifications to account…
Happiness is having plenty of hydrogen
As I understand it, there has been a desire or requirement to have the capability of surviving a cryo-tank failure at any time in the lunar mission. After C’, it was decided to keep the IMU powered up throughout all lunar missions even though it might be at the cost of having the backup cryos….
DPS low level propellant light
During our final review of the Descent Mission Techniques on May 28, GAEC presented a comprehensive review of the low level DPS propellant light – its operation and accuracy. The most significant piece of information coming from this was that we are assured of about 98 seconds more DPS operation at the hover thrust level…
C’ Abort Maneuver Overburn Monitoring
In response to a C’ Mission Techniques action item, Rick Nobles informs me that they have established the burn monitoring procedure to guard against overburn during any non-nominal C’ maneuver. As a standard procedure the crew should manually shut down the SPS as soon as the duration of the burn exceeds the nominal value by…
Lunar Reentry Mission Techniques meeting – March 21
On March 21 a small group of us ???? ??????? the logical flow charts TRW produced based on our ??? Lunar Reentry Mission Techniques meeting a couple of weeks ago. A couple of things came up that I should probably pass around….
Let’s move the recovery force a little
Jerry, I’ve done a lot of joking about the spacecraft hitting the aircraft carrier, but the more I think about it the less I feel it is a joke. There are reports that the C Prime command module came down right over the aircraft carrier and drifted on its chutes to land 5,000 yards away….
Ascent with busted guidance and control systems
On June 11 we had a Mission Techniques meeting to discuss manual ascent from the lunar surface. The term manual ascent, though, is somewhat misleading since most of our discussion had to do with how the guidance systems should be operated if certain of its components failed prior to ascent. In summary, I think everyone…
C’ Earth Orbit and TLI Mission Techniques Open Items
It appears we have the Earth Orbit and TLI Mission Techniques for the C’ pretty well under control. The only two significant open items that I know of deal with the optics check and the crew procedures for protecting against an SIVB engine cutoff failure during TLI….
