The first P52 for A11 around GET 00:50:00, to date I've only done this with whatever stars I could find....however I noticed that historically was done with stars 30 and 37.
Curiously I've repeatedly found that I cannot sight these stars without using the SIVB to manuver to sight these stars without exceeding allowed trunnion angles. (The trunnion angles exceed 90 degrees in the time frame of the P52 which is not permitted by P52 for sightings).
I also don't notice in the flight journal or mission reports any mention of SIVB maneuvers (Buzz mentions only SIVB at orb rate).
I don't see from the sources I've checked that any kind of clear mention of crew controlled attitude changes of the SIVB in parking orbit prior to TLI. The only thing I've found is a mention at
002:04:12 "Guidance to IU".
This could imply that the switch was sent to CMC (implying crew control over attitude) or it could just be calling out a check.
Before I scour the MCC audio loops does anybody have any thoughts how the historical stars would have been usable for P52 at this time without maneuvers? If maneuvers were in fact performed, if Orbiter is something 'out' with regards to this.
