I just love it when people make remarks like this without backing up their claim to debunk. Do your own research and present your findings. Don't leave remarks that you can't back up.
Quoting something from the 1st page tells me a lot about your "research" aswell.

This Incredulity/Disingenuousness gambit is getting really old.
To answer your question: Other communists, and communist elements in the USA. If they could prove, in an international court of law, that the US faked the landings, that would be a staggering blow. In fact, they could use their own partisan press to do so, or the press in any country that was capitalist but not necessarily a US ally, such as Switzerland. ]
When are yo going to admit that you made a mistake?
The solar wind is a stream of charged particles ejected from the upper atmosphere of the Sun. It mostly consists of electrons and protons with energies usually between 10 and 100 keV. The stream of particles varies in temperature and speed over time. These particles can escape the Sun's gravity because of their high kinetic energy and the high temperature of the corona.
The continuous stream of particles flowing outward from the Sun was first suggested by British astronomer Richard C. Carrington. In 1859, Carrington and Richard Hodgson independently made the first observation of what would later be called a solar flare. This is a sudden outburst of energy from the Sun's atmosphere. On the following day, a geomagnetic storm was observed, and Carrington suspected that there might be a connection. George Fitzgerald later suggested that matter was being regularly accelerated away from the Sun and was reaching the Earth after several days.
The solar wind is divided into two components, respectively termed the slow solar wind and the fast solar wind. The slow solar wind has a velocity of about 400 km/s, a temperature of 1.4–1.6×106 K and a composition that is a close match to the corona. By contrast, the fast solar wind has a typical velocity of 750 km/s, a temperature of 8×105 K and it nearly matches the composition of the Sun's photosphere.[20] The slow solar wind is twice as dense and more variable in intensity than the fast solar wind. The slow wind also has a more complex structure, with turbulent regions and large-scale structures.
The solar wind is responsible for the overall shape of Earth's magnetosphere, and fluctuations in its speed, density, direction, and entrained magnetic field strongly affect Earth's local space environment. For example, the levels of ionizing radiation and radio interference can vary by factors of hundreds to thousands; and the shape and location of the magnetopause and bow shock wave upstream of it can change by several Earth radii, exposing geosynchronous satellites to the direct solar wind. These phenomena are collectively called space weather.
Mercury, the nearest planet to the Sun, bears the full brunt of the solar wind, and its atmosphere is vestigial and transient, its surface bathed in radiation.
Mercury has an intrinsic magnetic field, for normal solar wind conditions, the solar wind cannot penetrate the magnetosphere created around Mercury, but particles only reach the surface in the cusp regions. During coronal mass ejections however, the magnetopause may get pressed into the surface of the planet, and thus in these conditions, the solar wind may interact freely with the planetary surface.
Earth itself is largely protected from the solar wind by its magnetic field, which deflects most of the charged particles; however some of the charged particles are trapped in the Van Allen radiation belt. A smaller number of particles from the solar wind manage to travel, as though on an electromagnetic energy transmission line, to the Earth's upper atmosphere and ionosphere in the auroral zones. The only time the solar wind is observable on the Earth is when it is strong enough to produce phenomena such as the aurora and geomagnetic storms.
The Earth's Moon has no atmosphere or intrinsic magnetic field, and consequently its surface is bombarded with the full solar wind. The Project Apollo missions deployed passive aluminum collectors in an attempt to sample the solar wind, and lunar soil returned for study confirmed that the lunar regolith is enriched in atomic nuclei deposited from the solar wind. There has been speculation that these elements may prove to be useful resources for future lunar colonies.
Recently the studies of the solar wind – moon interaction became unexpectedly relevant to the fundamental question for the lunar research, namely, the presence of water on the Moon. Since the first sample return missions of the 1960s, lunar scientists firmly believed that the Moon is entirely dry. The data recently obtained by Chandrayaan-1 and the re-analyzed observations from Cassini and Deep Impact fly-by’s challenged that notion: infrared spectroscopic measurements have unambiguously detected absorptions near 3 μm on the lunar surface that are almost certainly due to hydroxyl and/or water. The absorption line strength increases toward the lunar poles and the spectral feature varies in strength with time, suggesting that the water is in a process of rapid and dynamic migration across the lunar surface. Two most important continuous sources of water include (1) reduction of lunar divalent iron in minerals to metallic iron by solar wind protons being implanted into the surface, producing water, and (2) liberation of water from the impact of interplanetary dust and small meteoroids. All these recent findings and discoveries clear indicate that our knowledge of the only Earth’s moon is surprisingly limited.
NASA's THEMIS mission has overturned a longstanding belief about the interaction between solar particles and Earth's magnetic field.
And it shows us that Apollogists are ready to admit they dont know what is going on, but wont admit that Hoax believers could be correct. But that doesnt make sense, if you dont know what is going on, you cant come to the conclusion that someone is wrong. Unless there is a clear mistake with his argument.

Suffice it to say: no. The VAB and Solar Wind are two different things. The VAB is in Earth's magnetosphere. Solar wind delivers many of the particles, but not all. The moon is not within the belt. Any impact the solar wind would have on the moon is separate from the VAB.

So in essence, doesnt the Van Allen radiation belt extend all the way to the moon due to the fact it is composed by the elements of the Solar Wind? In other words, just because you get past the VABs doesn't mean you get past high energetic solar particles being streamed by the Sun's Solar Wind.
edit on 12-6-2011 by FoosM because: (no reason given)
According to NASA Solar Wind can damage space ships and astronauts.

the question was to DWJ
So, just to be clear on your statement, are saying that by trying it ourselves, lends creditability to our theories??
You can't be serious...your saying that the moon is has irradiated by the solar winds as Mercury is??

We all know what would happen to the Earth if we lost our atmosphere..

The moon's average distance from the sun is the same as the earth's average distance from the sun. When you think about it ... the moon orbits around the earth, so it's closer to the sun half the time, and farther from the sun half the time ... averaging out to the same distance from the sun as the earth is.
In any case, the moon averages 238,000 miles from the earth, which is less than 1/4 million, and that doesn't make much difference compared to the 93 million average between the earth and the sun ... less than 1/4 of 1 percent.

I recently talked with Kasper about the solar probe, why we want to get that close to the sun, and why the spacecraft won’t burst into flames. You’ve created Solar Probe, which will enter the atmosphere of our sun. This is the first time a spacecraft will go there? Oh yeah. One astronomical unit (AU) is the distance between sun and Earth. Nothing has ever gotten closer than the orbit of Mercury—that’s 0.31 to 0.46 AU from the sun. In the ‘70s a pair of spacecraft called Helios used an encounter with Mercury to change their orbit, and their closest approach was 0.29 AU.
Yes. but what we are discussing is, if it could destroy spacecrafts and kill astronauts during a trip to the moon.
