Light weight LM attitude control is too sporty.
Pete Conrad expressed concern the other day about a problem he anticipates in attitude control of the LM. This has popped up on a number of occasions previously, but nothing much gets done about it. Specifically, as Pete says, the LM is too sporty when in a light weight configuration. Minimum impulse is expected to…

You forwarded that memo to me questioning whether our Data Priority Coordination group had looked into this subject and,…

Can MSFN figure out where the LM is on the moon’s surface?
Rod Rose sprung one on me the other day I would like to ask you about. He says that the MSFN should have a pretty good capability of determining the LM’s position on the lunar surface given one day’s worth of observation – such as during the lunar landing mission. And that this could be…
Some lunar landmark tracking questions

First, I talked over our decision to delete this activity with Chris Kraft and he was relatively noncommittal. However, with regard to my comment that landmarks to the west of the landing site would be in darkness, thus invisible,…

The purpose of this memorandum is to recommend that action be taken to…
