There are so many other events that I am sure you DO believe happened, such as the sinking of the Titannic, WW1, the Wright Brothers first flight, the fall of the Berlin Wall, the Florida Marlins winning the World Series in 1997. All of these events were well documented, some a lot more than others, and we believe they happened becuase of what we know from history. Both the Mercury missions (7, I think) and Geminii missions (12, I think) were a testing ground and a lead into the Apollo programme and ALL of these programmed missions were followed in great detail by the press of the time. from these we have thousands upon thousands of detailed photographs, film and video footage, documentation, left over artifacts, and many hundreds of thousands of scientists, engineers, and people who worked on the projects throughout the very late 50's, 60's and early 70's. Many of these people continued onto other space programme work, but also many thousands left or had to be let go as Apollo came to an end and space funding was reduced. There is also about 800kgs of moon rocks returned by the astronauts, which many of the worlds top geologists have studied and all agree they are not rocks found anywhere on earth. Many of these geologists are from countries with no alleigiance to the US, in fact some were openly hostile during the cold war years. So with the sheer weight of evidence in favour of the Apollo moon programme and landings, which must be massively in excess of many of the events I listed above, there are still people who still believe the moon landings were in some way hoaxed, yet never seem able to produce any actual concrete evidence to prove it. We often end up with "it just doesn't look right" (well then, what SHOULD pictures of the moon look like?), and a lack of interest or understanding about the science involved. Yet these same people are still happy to believe that the Wright Brothers contraption actually flew ("I mean, have you SEEN it? It's all string and wood and cloth - can't possibly have flown...."), the Titannic sank ("I'm QUITE SURE they would have spotted something as big as an iceberg, that could do that much damage, much earlier...").... etc ... etc.....

The resolution of an optical telescope operating under perfect conditions is about 0.8" divided by the diameter of the telescope. We need to place the telescope at earth, so that everyone can verify that no false images are inserted by evil MIB. If we assume that we need to resolve features no more than 10cm big at a distance of 364,567km (perigee) -- a conservative guess at least in my eyes -- the resolving power has to be at least 0.6mas and minimum aperture size is then about 1400 meters.I suppose telescope technology could push this value down (3.6m wide CFHT at Hawaii has a PSF of only 0.13"), but we need to keep the system simple for those who want to inspect our little telescope ![]() Last edited by Forskern; 30-September-2006 at 09:49 PM.

Just a quick note, I've seen a bit of confusion on the mass of the returned moon rock, presumably due to unit conversion. There was a total of about 379 kg or ~834 pounds of moon rock.
See here, for instance: http://www.nasm.si.edu/research/ceps...ls_return.html

Isn't it though? No big. I see this every now and then. With different units, it's easy to make a mistake.

True enough. OTOH, it was NASA that was out both the money and the data from the probe.

It could have been worse, I mean it's not like they dropped a multimillion dollar satelite, or installed some switches up the wrong way or anything.......
