perhaps you like this one better ?
whay are you including probes that crashed ? to help me prove my point ?
this probe brought back BM ???
let me take a page out of skeptic friends book
Either way, you still owe me photographic evidence or any kind of evidence these probes brought back moon rocks
The 3 Luna missions collected .326 KG of rock, and BM is much bigger than all of the rocks brought back by those 3 missions combined !!! 1 rock !!!
Yet you think 1 probe could lift it and bring it back ? Without anyone in NASA even being aware of it ? c'mon
it's very simple. The mirrors and rocks are proof man was on the moon. We left something behind, and brought something back.

so dig into your files and show me independently verified evidence of 2,000 unmanned probe launches that brought back moon rocks.
Even though professor Van Allen has said the radiation wouldn't have been a problem due to the speed the astronauts went through the belt bearing his name, you desperately cling to that theory like a drowning man clings to a life preserver.
that's weak. I might as well discuss this with my 2 year old.
In practice, Apollo astronauts who travelled to the moon spent very little time in the belts and received a harmless dose. Nevertheless NASA deliberately timed Apollo launches, and used lunar transfer orbits that only skirted the edge of the belt over the equator to minimise the radiation. Astronauts who visited the moon probably have a slightly higher risk of cancer during their lifetimes, but still remain unlikely to become ill because of it.
Needless to say this is a very simplistic statement. Yes, there is deadly radiation in the Van Allen belts, but the nature of that radiation was known to the Apollo engineers and they were able to make suitable preparations. The principle danger of the Van Allen belts is high-energy protons, which are not that difficult to shield against. And the Apollo navigators plotted a course through the thinnest parts of the belts and arranged for the spacecraft to pass through them quickly, limiting the exposure.
The Van Allen belts span only about forty degrees of earth's latitude -- twenty degrees above and below the magnetic equator. The diagrams of Apollo's translunar trajectory printed in various press releases are not entirely accurate. They tend to show only a two-dimensional version of the actual trajectory. The actual trajectory was three-dimensional. The highly technical reports of Apollo, accessible to but not generally understood by the public, give the three-dimensional details of the translunar trajectory.
Each mission flew a slightly different trajectory in order to access its landing site, but the orbital inclination of the translunar coast trajectory was always in the neighborhood of 30°. Stated another way, the geometric plane containing the translunar trajectory was inclined to the earth's equator by about 30°. A spacecraft following that trajectory would bypass all but the edges of the Van Allen belts.
This is not to dispute that passage through the Van Allen belts would be dangerous. But NASA conducted a series of experiments designed to investigate the nature of the Van Allen belts, culminating in the repeated traversal of the Southern Atlantic Magnetic Anomaly (an intense, low-hanging patch of Van Allen belt) by the Gemini 10 astronauts.
In his book, Moonwalker, on pages 199-200, Charlie Duke recounts a dream he had prior to Apollo 16. In the dream, he and John Young were driving the Rover and came across some vehicle tracks. After getting permission from Houston to investigate, they came upon a car that "looked very similar to our rover - and it in it were two people...There was no movement from the two astronauts, and we couldn't see their faces because the sun visors were down." In the dream, Charlie then raised the visors and saw himself. The other astronaut looked like John. Houston had no explanation and asked John and Charlie to bring back samples of the vehicle and the suits for analysis, which showed that the vehicle and its occupants had been on the Moon for 100,000 years.

Tahir Rahman has created a large-format image ( 60k ) showing the reflections in Buzz's visor as captured by Neil in the famous photo, AS11-40-5903. Note that, in addition to the LM, Neil, the US flag, and the SWC, we can see the Earth reflected near the top of the visor.

You know its almost like a used car lot up there... what at least 6 of those buggies lying around?

If that little dot in the visor is the Earth, then how come other NASA images show it THIS large

I'm not interested in artists renderings or pure speculation, your friend in high places has already muddied the waters with too much of that already

Ummm perhaps because the reflection is on a round surface?

It's a common tactic to pretend that the belts extend uniformly around the planet, when they DON'T. The thickess parts of the belts are in equatorial orbit, and NASA stayed away from that region.

The first burn of the Agena engine they made was 80 seconds long and put them in a 294 by 763 kilometres orbit. This was the highest a person had ever been (until the next mission when Gemini 11 went to over 1000 km).
In 1998, the Space Shuttle flew to one of its highest altitudes ever,
three hundred and fifty miles, hundreds of miles below merely the beginning of the Van Allen Radiation Belts. Inside of their shielding, superior to that
which the Apollo astronauts possessed, the shuttle astronauts reported being able to "see" the radiation with their eyes closed penetrating their shielding aswell as the retinas of their closed eyes. For a dental x-ray on Earth which lasts 1/100th of a second we wear a 1/4 inch lead vest. Imagine what it would be like to endure several hours of radiation that you can see with your eyes closed from hundreds of miles away with 1/8 of an inch of aluminium shielding!
