The NASA edict against data destruction was issued after the space agency's 2006 admission that it couldn't locate the original tapes of the Apollo 11 live slow-scan TV broadcast from the moon. The agency then initiated a search for the tapes, which remains ongoing, as is the Internet furor the admission generated among conspiracy theorists, who believe the landings were staged.

The data is assumed to be on 1-in. tapes, but, based on period photos, Wingo thinks they should be on 2-in. tapes like the Lunar Orbiter data. He is conducting his own search.

Begging to differ is Richard Nafzger, senior engineer at the Goddard Space Flight Center in Greenbelt, Md., who's been working for NASA since 1968 and was involved in television support and voice communications for the Apollo moon missions.

Orbiter image from 1966, and, below, after modern processing of the original data."Despite how old you get, there are certain things you don't forget, and we recorded all slow-scan images on 1-in. tapes that were 15 in. in diameter, and I have spent the last three years tracking them," he says. "I am certain that there was no slow-scan ever recorded on the Ampex 900." The video feed was one of 12 tracks of telemetry that were recorded on each tape, Nafzger explains.

Due to the low wattage of the transmitter on the lunar lander, they had only 500 kHz bandwidth to use for video, as opposed to the 4.5 MHz that was standard at the time for broadcast analog TV. So NASA used a slow-scan, black-and-white transmission at 10 frames per second with 320 lines per screen, Nafzger says. U.S. broadcast TV used 30 frames per second with 525 lines per screen. The conversion was made at each ground site with a device that basically pointed a broadcast TV camera at a special monitor displaying the slow-scan image.

"The night we landed and did the moonwalk, that is when I became scared," he recalls. Before that point, there hadn't been as much pressure to broadcast the proceedings in real time. But after the safe landing, "they were saying that they had better be able to see this on TV, and 600 million people were watching. Something as simple as plugging a wrong patch or pushing a wrong button would mean that no one would see it," Nafzger says.

Indeed, the camera had been installed on the lander upside down, Nafzger recalls. The TV technicians heard of this at the last minute and scrambled to install converters at the ground stations. The first few seconds of broadcast were upside down because the operator at the Mojave Desert ground station who understood the converter had left for the day, Nafzger recalls.

If the original tapes could be found, he estimates that they would appear three times clearer than the broadcast images. "Taking the clean data and extracting it in a digital high-definition format would let you go frame-by-frame and remove the noise, smearing, contrast problems and other things that were man-made, mostly by the original conversion. The tapes are worth getting just for that reason -- absolutely," Nafzger says.

We will NEVER see the original tapes because it will prove that what we were fed on the tv was re-creations of the moon walk because the powers that be do not want us to see the truth: Artifacts, building and craft active on the moon.

Why have we not gone back?

A very well played act by NASA and the TV networks to make people bored with the space program. Plus, I'm pretty sure that whoever we met on the moon told us NOT to come back.

Somehow I think that we have been back and actually still have a presence there, much to the chagrin of the beings that have been living there since the dinosaurs walked the Earth.

We are supposed to be going back soon, but my bet is something major will "happen" and the whole thing will be "officially" put off for years.

That's an odd way to put it. The plan had always been to attach the camera "upside down" on the MESA. That's how it could be attached, so Neil could lower the MESA on a tripline and there would be a camera to catch the first steps. After that, it would be re-mounted on a tripod outside the LM.

Not sure when they put a switch in to reverse the picture, but it had been there for a while. There was some business, I recall, about forgetting to flip it until after they had video coming in.
