Interesting. I had not thought of this.
Googling “Moon Over China” revealed this view which is definitely NOT the North America view.
Cool.

Area 51, area 51. I’m so tired of hearing about the oh so secret area 51.
Don’t you fools realize that this aircraft test site serves a dual purpose. All the UFO nuts and such keep it in the public eye.
And no one pays any attention to area 47.
The common man is so easily duped.

Make that every 29 days, and you’d be right!
The moon revolves on its axis once per orbit. That keeps roughly the same side facing earth at all times. Because the moon’s orbit is not circular, we can actually see about 59% of its surface over the course of a month. This apparent wobble is called libration. (Be sure to click on the photo to see the gif animation)
You’re part right! I did a bit of research. Wikipedia article on tidal locking.
The moon does a complete rotation once every 29 days, 12 hours, 44 minutes and 3 seconds long. This is the “lunar day”. So if you stood on the moon, it would be 29 Earth days and change from one (lunar) noon to the next.
The moon orbits around the earth once every 29 days, 12 hours, 44 minutes and 3 seconds. This is the length of one lunar cycle (i.e. full moon to full moon, viewed from Earth).
So basically, the length of the lunar day, and the length of earth’s lunar month is the same.
No matter where you stand on Earth, you only see the one side of the moon that is always facing the earth.
IRL, it’s slightly more complicated than, as even though only one side of the moon faces the Earth, the side is slightly bigger than 180 degrees. This is because the moon slightly wobbles. This is called libration. I don’t really understand it well enough to explain it. Here’s the Wikipedia article on libration, with an animated picture of the cycle.
I knew I should have previewed! Thanks Squink.
The Libration gif was very interesting. The rotation thing is pet peeve of mine. Being a SciFi junky it really irks me when some writer unwittingly puts an alien base on the side of the moon that earth will never see. The latest casualty was an episode of Earth Final Conflict.

Seeing as we only see 59% of the moons surface, it would be quite possible to put an alien base on the far side and we wouldn’t be able to see it.
Oh and did anyone zoom right into the moon on moon.google?
No idea, but I know that ‘Darkside of the Moon’ causes people to smoke marijuana and/or do other drugs

A real scifi junky would have enough astronomy to know that the moon rotates in 29 days, not 24 hours, and that nearly half the moon can’t be seen from Earth, and that the same moon can be in the sky in both America and China at the same time, on account of there being less than 12 hours between them, and hence that it was patently absurd that different faces could be seen in America and China. So your irritation at Earth Final Conflict is misplaced, as five minutes with any halfway decent astronomy text could have told you.

Your astronomer friends are dyslexic. If it were spelled Kupier it would be pronounced as you suggest. But its spelled “Kuiper” and it does rhyme with hyper.
I believe it is of Dutch origin.

That relieves a minor worry, 'cos I know “ij” makes the “eye” sound in Dutch (or at least in Flemish, which AFAIK is mighty near the same). Must be one of these Euro vowels that transmogrifies as it crosses the Atlantic, I mean, if Dr Seuss lived in Germany he’d pronounce it “Soyce”, 'cos the “eu” is the same as in “Deutchland”.
Very possibly. And maybe I am too, now that I look at it. This might be one of those persistent mispronunciations like “sherbert” or “nucular” that get started and don’t go away easily.
I stand corrected.
Although the Hubble can’t see the Apollo landing sites, earth based observatories can “see” the laser reflectors that three of the missions left behind.
I attribute my wobble to Libation.
jus a leetle jokes.
That…that’s a whoosh, right? Cuz that’s the same view I get in Colorado Province. I recognize the Energizer Bunny in the moon.
Yes, I did. So it’s really true.
Just to clarify: Wrong. People in China see what we see. The EARTH rotates once every 24 hours. Everyone on earth at any particular latitude looks up and sees essentially the same thing, but later or earlier in the day than everyone else at that latitude. A full moon over Miami (musical accompanyment kicks in) overhead at midnight on Aug. 19, will be seen overhead by everyone on earth at that latitude when it’s midnight wherever they are. Yes, there will be a very slight change through that 24 hour period as the moon’s phase continues to wane ever so slightly, but it would hardly be noticeable, and everyone will have a full moon, and it will be the same full moon that we see. Same side. In fact, except for occasional lunar orbiting vehicles and picture takers, no one has seen the other side. This side, as mentioned above, is smoother. Easier to plan a manned landing where there aren’t Cleveland-sized divots everywhere. xo, C.

In all those cop shows (CSI, NCIS) where they have a photo and the lab tech is asked to look for finer details - they always manage. Having framed and cropped enough digital images in photoshop, I always say: “Nah - can’t be done.” But then, it keeps showing up and I wonder if I’m missing something and there are super computers with extra special software that can actually do this.
