I agree about the atmospheric drag not being a major effect. You are right about Apollo 9, I don't know how I missed that it was an Earth-only flight. However, the reason I was misled was that in reading the Apollo 10 recontact analysis document it mentioned that the analysis for the Apollo 9 SLA panels was applicable for Apollo 10, which was not really right. >>Then there is the matter of midcourse correction. How does that >>affect the position of the panels? Maybe it improves it or maybe >>worsens it. >Yes, but I haven't seen anything to suggest that NASA or anyone >else knows for sure. The Apollo 11 mission report states that the midcourse correction occurred at 26 hr 45 min and was an increase of velocity of 20.9 ft/sec. This appears to be fairly close to the direction of motion (velocity change along X axis =-14.19 ft/sec, Y axis= +13.17 ft/sec, Z axis=+7.56 ft/sec in the earth centered interial coordinate system). So we can basically assume that the spacecraft sped up by 20.9 ft/sec. The crew sighted the UFO at 60 hr 49 min. So the total time which the SLA and CSM diverge from the midcourse correction is about 34 hr and 4 min or 122640 seconds. 20.9 ft/sec over this time period gives 2563176 ft or 421 nautical miles/485 statute miles/781 km. This does not include the divergence due to the jettison velocity which at best is supposed to be 8 ft/sec. The SLA panel jettison occurs at roughly 3 hr 17 min giving 57 hr and 32 min of travel time (207120 sec). For 8ft/sec over this time period gives 1656960 ft/272nautical miles/314 statute miles/ 505km. Combining the two axes/dimensions of divergence provides a total distance of the SLA panels from the CSM of 577 statute miles/930km! So it was far behind them. Now given the size of 22 m^2 area, it would likely have a visual magnitude well within the human eye's ability to see (3-4) so would have appeared as a bright dot with the eye (similar to rocket bodies seen from the ground by sky watchers). Yet the crew debrief clearly states, "Aldrin: Of course, we were seeing all sorts of little objects GOING BY at the various dumps and then we happened to see THIS ONE BRIGHTER OBJECT GOING BY (my emphasis). We couldn't think of anything else it could be other than the S-IVB. We looked at it through the monocular and it seemed to have a bit of an L-shape to it." So this really completely rules out the SLA panels because there was no way for the panels to PASS the command module (in either direction). The panels, due to the midcourse correction have caused the panels to be left far behind. Their jettison speed could never match/exceed the mid course velocity change. I also checked the S-IVB distance (I found the trajectory coordinates in a publication) and it is about 9000 miles away (and behind) the command module at the sighting time. Therefore, the UFO sighting remains an unknown, although I think it is likely the same kind of debris seen around Shuttles/ISS, namely tiny stuff. I have watched alot of the video of Apollo and they had alot of debris during parts of the missions. >As I said before, what I find most interesing about this case is >that Alrdin changed his story.

Yes, I agree it is unlikely an SLA panel on these grounds too.
