The shadow runs up almost all the way to the foot of the mountain as well indicating how close it is. Personally I think it is quite possibly a fake background which explains the issues raised much better than what I have heard so far of "rational" and "scientific" explanations.

People are used to having certain visual cues to judge distances, such as the size of a building or another car on the horizon, Li explained. But the moon has no such cues. Getting lost, or misjudging a distant object's size and location would be easy, and extremely dangerous.
He described incidents during past lunar missions when astronauts were traveling to a target site such as a crater, and got within a few yards of it -- but couldn't see the crater because of difficult terrain.
"They were so close, but they had to turn back for safety's sake," he said.
Keeping astronauts safe will be a top priority for Li's team, which includes experts in psychology and human-computer interaction as well as engineering.
"We will help with navigation, but also with astronauts' health as well," Li said. "We want them to avoid the stress of getting lost, or getting frustrated with the equipment. Lunar navigation isn't just a technology problem, it's also biomedical."
Li explained how the system will work: images taken from orbit will combine with images from the surface to create maps of lunar terrain; motion sensors on lunar vehicles and on the astronauts themselves will allow computers to calculate their locations; signals from lunar beacons, the lunar lander, and base stations will give astronauts a picture of their surroundings similar to what drivers see when using a GPS device on Earth.
It's just too bad we lost the technology to go to the Moon.
Nasa says now they will focus on unmanned missions in the future.
Its strange they said they could not see the stars with the naked eye on the Moon, if they looked straight up for a bit, no way they should not be able to see stars.
Its also strange so few test flights they had before touching down on the Moon with manned spacecraft.
Its also strange nobody but NASA has tested the spacesuit. Was it tight in a vacuum with the needle and thread sttiches? Was it possible to move the fingers in a vacuum? Who knows? only NASA.
Neil's cryptic behavour and speeches...
look at 2:27, very strange how he gets up after the fall

Untrue. That is completely misunderstood, from reports that surfaced about certain details and technical specifications of the OLD machines used in the Apollo era being no longer available. Who cares, but museums?
...is it not true that we cant use the apollo spacecrafts any more...
...and it will be a very long time before we can go to the Moon again, especially with all the Ares rocket problems?
N1 test launches:
Feb. 21, 1969: The first test launch of the N1 rocket (Vehicle No. 3L) failed 68.7 seconds after liftoff.
July 3, 1969: The second test launch of the N1 rocket (Vehicle No. 5L) failed immediately after liftoff.
June 27, 1971: The third launch of the N1 rocket (Vehicle No. 6L) failed at 50.1 seconds after liftoff from the left pad of the Site 110 in Baikonur.
Nov. 23, 1972: The fourth launch of the N1 rocket (Vehicle No. 7L) failed about 107 seconds after liftoff.

It IS sad. Sad that because of stingy budgets, the current engineers have to resort to trying to reverse-engineer old designs.
BUT, we (and the Japanese, and the Chinese, and the Europeans, and the Russians...and maybe India???) have quite reliable rockets, right??
What about the Russian launchers (Proton?) to re-supply the ISS in between STS visits?
I'm not a Rocket Scientist (oh, I've waited sooooo long to type that!) but there are decades of experience with the good ole' liquid rocketry designs. I guess, really, the biggest deal about the Saturn were its main engines, no? THEY were the real marvels of engineering, because it only required FIVE of them to lift the needed mass for the Lunar missions.
By comparison, the USSR was struggling with their heavy-lift launch vehicle, the 'N1', attempting to get THIRTY smaller engines to work in unison to achieve the thrust needed.
Will Buzz Aldrin is working with the Chinese on anti gravity and gravity waves...
