Does
Mount Marilyn appear in the video? I don't see it, but I may have missed it.

Wouldn't all of the Apollo missions had to fly something along that path ??

What an incredible journey these astronauts had! Glad they got home safely!

But where are the stars?? Better with it to feel like a astronaut, no?!

You're not going to see stars in a photograph that is exposed to capture the Moon. They're not bright enough.

These images are not from Apollo 13 but are from a recent satellite circling the Moon. So why create a fake headline? Do you have to trick people into watching this cool video? How pathetic.

The headline accurately describes the video, which was created to show the view that Apollo astronauts had as they orbited behind the Moon. And the caption explains that clearly.

Cost and the need to focus on other difficult issues played a role in not establishing a system of
real-time communication back in the
Apollo days.
Will that need re-emerge for modern
lunar exploration I suspect the process will still need to deal with the moon's
lumpiness.

While it is difficult to maintain satellites in long term orbits around the Moon, it is also cheap and easy to launch them into orbit if you do it from the Moon. If we had a lab operating on the lunar farside, that would be a definite option.

As far as I understand, Apollo 13 made a polar trip around the Moon, while the other missions were in equatorial orbit to allow an easy landing and rendez-vous of the LEM.

Three things:
1. A salutation to Michael Collins, the first human to venture behind the Moon - alone. Can't imagine such isolation.
2.Is that an illustration of the increased crater incidence on the far side or just increased sun illumination on the near side?
3. Having been around for the entire space program, I very much appreciated this presentation. Almost like being there.

Wouldn't all of those still had to orbit around the 'far side' of the moon though ?

Don't the Chinese currently have a satellite 'behind' the moon, to communicate with their rover thats currently operating there.

Yes.
Behind as in orbiting the Earth-Moon L2 point, not orbiting the Moon at all. L2 isn't stable, so the relay craft needs to expend fuel to stay in position.
