    actually, that sounds like a description of the telegraph.

    I go further into digital coding in my post below to GG, "They never broadcasted from Mars... the latest rover is able to send pictures... "

    NS, I'll bet you I can find an EVEN MORE FUNDAMENTALIST "No such thang as space exploration" guy out there....who will say what Spamature said. That we not only didn't land men on the Moon....but didn't land Viking or other probes on Mars because "high energy Van Allen radiation would destroy their electronics....It's all shot at Area 51."

    I'll bet I can find one that thinks Days has been "duped" into even believing we put men in ORBIT....claiming "Without an atmosphere, you'd be exposed to high levels of UV radiation from the Sun. High levels of ultraviolent light cause sunburns...yet the astronauts 'return to Earth' without sunburns. EVERYTHING since Gagarin was a fake!"

    It's not a matter of the junk science....the contradictory "logic"...it's a RELIGIOUS matter. Same as it is for Creationists who come up with ways to "drown the dinosaurs in Noah's Flood" and have their bones "look" like they've been buried for millions of years and fossilized.....or how "God created apes (Austrolpithecenes, even Neanderthals) that died off during the Flood. Adam and Eve were first and were Cro-Magnons."

    why is it all or nothing? Life is complicated. NASA has kicked some serious space ass, they are awesome. Heck, they even gave us a moon hoax in with the low earth orbit missions.

    manned spaceflight has some hurdles to get over. We sent mapping missions to the moon before the Apollo flights... we just can't build an environment for humans that will survive the rigors beyond low earth orbit... yet. Don't give up, it will happen. Remember what JFK said? Going to the moon is hard. This is going to take more than one decade, is all.

    In between the conspiracy nuts and the debunkers lies nothing but confusion (not the truth)

    quit focusing on that crap. Look at the science. There's the truth.

    Because if you're right they put more effort into scamming us with a fake space program than they did into the actual real space program.

    hardly. The movie was expensive, but not as expensive as spaceflight. Plus, the communications all got used. They did broadcast tv from low earth orbit. It wasn't just wasted on the hoax.

    Days, in the next 20 years, the Chinese are planning on going to the Moon.

    I'd say you Moon Hoaxers better get started on your "reason" why they're going to "fake it".

    Friendly heads-up. :)

    It's going to be dangerous, and they haven't solved radiation shielding yet. If man ever does walk on the moon, he won't be wearing a playtex bra. The moon is chock full of a razor sharp rock called obsidian. One tiny slice to the atmosphere suits and the great vacuum of space sucks all the air out and the man's blood boils and he dies faster than you can say, "oops, I shouldn't have got bored and started kicking that boulder around."

    There are a number of ways engineers made that signal smaller. First they dropped the color information. If you only have to send intensity information (i.e., a black and white picture) you can cut the bandwidth by two-thirds (Fig. 2, top). Then they reduced the number of horizontal lines (Fig. 2, middle). This of course reduced the clarity of the image, but it cut the signal size by a third. Then they reduced the number of frames per second (Fig. 2, bottom). This reduced it by two-thirds. The result was a signal that could be squeezed into the limited data-carrying capacity of the small antenna, requiring only about 5% of the information of a standard full color signal.

    I read up on the color wheel, the way the signal was disassembled to reduce the broadband, went through the whole nine yards on that signal. When I tell you that it was 180,000 miles out of range, that is after giving it the benefit of the doubt for the work they did on it. The Clarke orbit is only 22,000 miles out. That's what NASA ordered equipment for. I'm giving that signal a range of 50,000 miles; that's over twice as far out as the Clarke orbit.

    Do you know how Apollo 11 supposedly sent the footage of Armstrong climbing down the ladder? With a fixed two foot dish on the roof of the LEM. Think about how small a target the earth makes for that two foot dish. Unless that dish was aimed directly at the earth, even if it was just 2 degrees off in any direction, the signal was totally lost. Think about it. So wouldn't you think that the LEM would be built with an adjustable dish and that they would aim the dish at earth and test the signal before he stepped out the hatch? (If they were really on the moon and really trying to send a tv signal all the way to earth for the very first time).

    Why did they bother to set up a six foot dish on the moon if the 2 foot dish was working perfect? BTW, those rover shots sure had great clarity without any equipment to tune the signal, it was a straight transmitter to dish hookup.


    How exactly did that dish on the back of the rover manage to nail the earth perfectly with its signal even while the rover turned in circles? (Look at the dish, it is aimed at an angle)

    stop. think. any of these points are impossible. the reason I only put a single point in the top post is because people read over multiple points and dismiss them all with a wave of a hand. Like you tried with the signal range. The earth is only 8000 miles in diameter. The dish on back of the rover was aiming all over the place in a grid roughly 300,000 miles in diameter; the signal that is out of range is not even aimed at the earth for any of the time it is attached to the rover. If the signal hit the earth by chance, it lasted one or two seconds and then was gone again. But we have these neat Apollo clips of full transmission from the back of the rover... none of the Apollo missions needed to ever aim a dish at the earth; the tv signal always was on target.

    on and on it goes. It was a hoax.

    What is the range on a low powered analog tv signal? (it hasn't changed) In broadcast mode, maybe a mile. Shot out of a five foot dish, maybe 50 miles. When I gave the LEM signal a range of 800 miles, that is assuming that the LEM had a power up amp... good luck confirming that, RCA built the equipment that went into the LEM and they went out of business before there was an internet. All of the television equipment was built for Apollo by the television industry. NASA just used what they bought on the open market. So, when you believe in the Apollo tv signal, you are believing that the same microwave analog signal that made hops of 15-35 miles back in the 1940's was able to leap to the earth from the moon. Did you know that the dish in Australia sent it over those old 8 foot dish hops across Australia? 8 foot dishes on those radio towers were larger than the dishes used on the moon, and the power of the signal was not low power as it was on the moon. In other words, the signal sent from the moon didn't go anywhere, our dishes on earth had to be able to go to the moon to get that signal... meaning they had to be half a mile in diameter, not 85 feet or that old 200 foot physics dish that they jury rigged for the Apollo signal.

    When you read how they supposedly did it, bear in mind, it is a boondoggle, they are LYING and they are not believing their own Lies, they are pushing propaganda at you. Remember, this whole hoax was just that: propaganda from Dick Nixon. It wasn't just aimed at the American public, it was aimed at the Russians. Do you think Nixon believed for one moment that Apollo really went to the moon?
