Does anybody else think that the NASA GRAIL's video of the Moon's far side is a CGI job? , page 7

You misunderstood, or I didn't explain adequately. What I meant was that the direction that the camera is pointing doesn't change. It remains pointed in the direction of the stars. As the probe orbits, the Moon moves into and through the frame.

Like this but of course since the stars are very very distant the slight vertical movement of the camera will not show any change in the angle. Only if the probe (and thus the camera) is rotated would the stars change position in the frame.

I don't know if the camera has zoom capability but the probe was and is currently in an elliptical orbit, it gets closer and farther from the Moon's surface at various points. I didn't show that in the sketch. The orbit will be circularized before the science mission begins.

The cameras in your diagram were worth 1000 words. I never would have thought they'd be oriented in that manner. I had everything based off of the incorrect assumption that the camera would always be pointed toward the center of the Moon. Kind of like if it were fixed to the end of the second hand moving smoothly around the face of a Rolex. So obviously no pics of the Moon when the cam is on the near side. So after all this it's safe to say there ARE stars in the vid. Yea, minor point debunked ! TY

There are 4 cameras mounted on the probe (aimed in different directions) and during the science phase of the mission the attitude of the probe will be changed in order to aim the cameras at targets selected by the middle school students. So there will be images from the near side as well.

Awesome, but I do hope they stay away from clear shots of that crater to the lower right side of the Zeeman crater at the end of that vid. It obviously has either a giant airplane or even more likely a huge statue of a swashbuckling alien grey skull complete with a knife in its mouth! But on a more serious note would you be inclined to illustrate sometime how the position of GRAIL lines up with the view in the vid on the 19th relative to the Sun so that the far side was illuminated. Isn't the phase of the Moon as viewed from Earth kind of irrelevant?

You mean Drygalski crater? Too late.

Yes, it is. A full hemisphere of the Moon is always illuminated from some vantage point, unless it's shadowed by the Earth during a lunar eclipse.

The probe entered lunar orbit around New Year's day. On this particular pass they happened to catch a full moon (from its POV) on the far side. It was a cool target of opportunity.

That's funny. I was so kidding but like you said "too late". At least this thread only has a reference to "apparent" lens flare rather than claims of "Lunar Magneto-Mass Ejection in NASA vid".
