Apollo 7 did not have a lunar module. They just pretended it was there to simulate docking. They had been planning on jettisoning the panels prior to Apollo 7 (March 1968). >>>The Apollo 15 >>>article I referenced indicated that the panels were jettisoned >>>when they were rotated on their hinges 45 degrees from the >>>booster axis, so I assumed that they were ejected at that same >>>angle to avoid a large part of the force of the springs just >>>causing the panels to tumble rather than move away from the >>>spacecraft. If the panels were ejected at a 45 degree angle, >>>they would have had a forward velocity component. Even if that >>>assumption is correct, the panels would still have ended up >>>about 265 miles downtrack from the spacecraft due to the >>>midcourse correction maneuver. And they would have beenat a >>>cross-track distance 221 miles away from the spacecraft for a >>>total distance of about 340 miles. That's still a bit more than >>>my original guesstimate. It would also put the panels behind the >>>spacecraft, while the UFO was sighted in the forward direction. I don't know about the Apollo 15 reference, but the standard method was to release the panels at 90 degrees. Later, it showed that up to 130 degrees from the x axis of the S-IVB was possible. But certainly 45 degrees was not a desired or planned angle to jettison them. Now if the S-IVB was pitched at an angle then you may get some forward velocity on some panels depending on the pitch angle and the panel angle. >>I do not see where it is stated that the UFO was sighted in the >>forward direction. They said it was tumbling and that it was >>"going by". >In the book _First Man_ Neil Armstrong gave his own version of >the panel explanation.

No way could it be _ahead_ of the spacecraft after midcourse correction. >>But the odd thing I just noticed in the Mission report is that >>during the time the object was sighted, the spacecraft was in >>passive thermal control mode.

So they _could_ see an object behind them. >>But the problem is now the interpretation of "going by".

Depending on the size/mass of the debris, wouldn't centrifugal motion move it away from the CSM? It would certainly help if the astronauts could have given better data on where the object was (toward Earth or toward the Moon, which axis the apparent movement of the object was going..along the CSM rotation axis or along the direction of motion axis). Without these, it is hard to get too excited about this astronaut observation.
