It's what I've referred to as trying to make smart people noises.Oh yes, the Donald Drumpf method for public speaking.

Sorry, that appears to be a post hoc ergo propter hoc logical fallacy;
You mean like spending millions of dollars on giant antenna arrays around the globe, such as Pine Gap, Australia to relay signals from orbiting space craft, and the moon back to Houston? Why didn't we think of that?...oh wait, we did.If you paid attention, the claim is it would take special and onerous logistics to achieve a stationary image without a [=geo] selenostationary satellite, which could theoretically be done by localised means.
No. It was simply NASA prioritizing what needed to be photographed while on the surface of the moon. In this case, the priority was to document the activities and the surface of the moon. Stars can be photographed from earth, and wasting film to do so would be stupid, and NASA doesn't do stupid.Sorry, that appears to be a post hoc ergo propter hoc logical fallacy; re your claim, there are no stars because either NASA didn't want them or 'It is not possible to film a starry sky from the Moon surface using Ektachrome ASA160'. There are no stars because who needs'em anyway..?
I'm leaning toward a mixture of dishonesty and incompetence. On the one hand, I suspect a genuine belief in her superior intellectual abilities. It's what I've come to refer to as someone who is just barely smart enough to recognize their own unrivaled genius. (I've used that description for people like Ayn Rand and Ben Shapiro.) On the other hand, there's an obvious psychological need to demonstrate her genius through the opposition of those who are jealous of her superiority - to believe that people dispute her claims because she's intellectually superior to them. I think she's probably aware of her exposed pretentiousness even as she believes she's genuinely the smartest person in the room.Even very stupid people who nevertheless mean well will still try to explain something as best they can. Instead, people who don't mean well will go to extraordinary lengths to avoid having to give any explanation and deploy a myriad of unconvincing excuses. I agree that evidence of deficiency shouldn't be taken as evidence of deception. But evidence of deception is simply what it is.
Now explain why such a satellite would be needed. Explain why a directional antenna on the moon can't point to the earth, and a directional antenna on the earth can't point at the moon, and the two send and receive transmissions between them.Selenostationary* satellite images for live TV broadcast from the Moon's surface without needing special logistics because of course, it would theoretically match the Moon's orbit.
*cf geostationary satellites

schematic (not to scale) of Hill spheres (as 2D radii) and Roche limits of each body of the Sun-Earth-Moon system. The actual Hill radius for the Moon is on the order of 60,000 km (i.e., extending less than one-sixth the distance of the 378,000 km between the Moon and the Earth).[9]

More importantly, Apollo didn't need a satellite.Apollo didn't use a satellite
Apart from the mission that had a camera specifically for photographing the stars.No. It was simply NASA prioritizing what needed to be photographed while on the surface of the moon.

People shouldn't have to decipher your sloppy use of idiomatic terminology peculiar to you, especially from a self-declared author, scientist, etc. You should be far more careful with your choice of words.
Now, can you explain what you mean by "geopositioned" or "geopositioning", because that most definitely is not clear from the context. No-one knows what you mean (most of all, you).
A good answer here:
"A more careful calculation, including the effects of the Sun is slightly more optimistic and provides a Hill radius of r=58,050km. In either case though, hopefully you can see that the radius for a selenostationary orbit is much farther than the Hill radius, meaning that no stable orbit can be achieved as it would be too much perturbed by the Earth and/or the Sun.
One final, semi-related point. It turns out almost no orbits around the Moon are stable, even if they're inside the Hill radius. This is primarily to do with mass concentrations (or mascons) in the Moon's crust and mantle which make the gravitational field non-uniform and act to degrade orbits. There are only a handful of "stable" orbits and these are only achieved by orbiting in such a way as to miss passing over these mascons."

When you take into account the working of her brain, as has been demonstrated over and over within this very thread, it should be obvious @Vixen is saying her many references to "geopositioned" and "geopositioning" were, in her addled brain, referring to the Hill radius.It may be a good answer to something. But it has no connection whatsoever to the post by JesseCuster that you quoted. Your "brain" works in very strange ways.
How does that explain what you mean by "geopositioned" or "geopositioning"?
No, that doesn't explain in any way what you mean by "non-geopositioned."
Are you trying to say that "achieved its 'hill'" means to orbit at an altitude exceeding the radius of the Hill Sphere?
You folks don't appear to understand how triple-niners talk and "think".A good answer perhaps, but not an answer to the question you were asked.
It doesn't explain what you meant by "geopositioned" nor what you meant by "achieve its hill".
The honest answers appear to be that you don't know. It was just some technobabble you thought sounded clever.
Please list the film speed, aperture and exposure time. Also please note the complete lack of any sunlit objects within the frame.Here's an example of how black and white photography is perfectly capable of producing a starry night photo.

The claim is utter ◊◊◊◊◊◊◊◊. There is no "stationary image". This has been demonstrated with the full TV transmission, showing that your source is a liar. It also shows that you'll believe a lie as long as it tells you you're smart for believing it.If you paid attention, the claim is it would take special and onerous logistics to achieve a stationary image without a [=geo] selenostationary satellite, which could theoretically be done by localised means.
This reminds me of the "backdrop" claims regarding the Apollo 15 images - how they're supposedly identical in every photo. But when you actually look at them, shifts in perspective can clearly be seen between each of the geology station stops.The image was not stationary. It changed aspect.
Again, your straw man arguments tell us just how aware you are of your failure to address what was really said.Sorry, that appears to be a post hoc ergo propter hoc logical fallacy; re your claim, there are no stars because either NASA didn't want them or 'It is not possible to film a starry sky from the Moon surface using Ektachrome ASA160'. There are no stars because who needs'em anyway..?

Neither of those posts says anything remotely close to what you claimed was said.How many photographers do you know shooting colour?Just because something's a best seller with the public, doesn't= quality. All the photographers I knew used Ilford.
What Ilford film do they use to shoot colour?
Hint, Ilford do not make colour film
Which of those Ilford films would have shown stars during Lunar daylight?Er, because some were professional (cf Keith Morris, Ansel Adams [_sp?] and others members of 'arty' camera clubs.
The funniest thing, I think, is Vixen's implication that if you can't see pretty stars in the background of the Apollo surface photos, "then what's the point of even going?". Like that one feature, assumed by many people ignorant of basic photography to be present in such photos, was so important that NASA should have made it their number INE priority for the missions.Vixen, please explain to me what would be the advantage of taking a photograph of stars using a hand-held camera on the surface of the Moon, over taking an image of the stars from the 5.1 metre Hale telescope at the Palomar Observatory, or the 2 and 2.7 metre telescopes at the McDonald Observatory, or the 3 metre Shane telescope at the Lick Observatory, the Hooker telescope at the Mt. Wilson Observatory, the 2.5 metre Isaac Newton at the Royal Greenwich Observatory.....
The telescopes listed above were all available at the time of the Apollo 11, and all could take long integration deep sky images.
There were also countless smaller telescopes capable of taking long integration images - Kitt Peak, Alfred Jensch, Carl Zeiss Jena, Ondřejov 2-m, Radcliffe (South Africa), David Dunlap, Mount Stromlo, Kottamia (Egypt), Perkins, Kaj-Strand, Kuiper, Oak Ridge, Bosque Alegre (Argentina), McGraw-Hill.... seriously, I'm just getting bored typing these now.
So, please, explain the advantage of a hand-held Hasselblad camera using ISO 160 film on the Moon. What would it show that couldn't be seen from any of the telescopes listed above?
Why would NASA want such images?
Please, explain it like I'm an 8 year old.
Wow! I just got here on the live thread. Thanks for all the likes! And I'm 15 pages behind again!Ok, 17 pages behind and won't post this until I've read some more. But if you want to look good in a glossy magazine, you couldn't have done better than Kodachrome. Paul Simon's "nice bright colors" and all that. But it was slow. ASA 25 (for the best pictures) or 64 (slightly less so.) Optimized for the conditions, you want something faster, like Ektachrome, ASA 160.
Wow, still 10 pages behind. I'll post and hope to get somewhat caught up tomorrow.
