WASHINGTON -- NASA will hold a media briefing at 11 a.m. EDT on Thursday, July 16, at the Newseum in Washington to release greatly improved video imagery from the July 1969 live broadcast of the Apollo 11 moonwalk.
The release will feature 15 key moments from Neil Armstrong's and Buzz Aldrin's historic moonwalk using what is believed to be the best available broadcast-format copies of the lunar excursion, some of which had been locked away for nearly 40 years. The initial video released Thursday is part of a comprehensive Apollo 11 moonwalk restoration project expected to be completed by the fall.
The Newseum is located at 555 Pennsylvania Ave. N.W. The news conference will be broadcast live on NASA Television and streamed on the agency's Internet homepage.
NASA Hints It's Found Missing Moon-Landing Videotapes
...Back on July 20, 1969, the raw video feed from the moon was beamed to the Parkes Observatory radio telescope in southeastern Australia, as well as two other radio telescopes in Australia and California. The feed was then compressed and sent to Mission Control in Houston.
Because of technical issues, NASA's images couldn't be fed directly to the American TV networks.
Instead, the grayish, blotchy images Americans saw on their TV sets were the result of a regular TV camera pointed at the huge wall monitor in Houston — a copy of a copy, in effect.
The rediscovered footage will still be in black-and-white, but will be much brighter and clearer than what we've been used to seeing for the past 40 years.
On Tuesday, NASA spokesman Mark Hess would not confirm to FoxNews.com that the new footage came from the lost tapes, admitting only that some of it had indeed come from Australia...
You're in a spacecraft, descending to land on the moon for the first time in history, and the microphone to Earth is off. What do you say?
"I would appreciate if you could ... see if you could ... find the map ..."
"Trade you that for a piece of gum. There it is."
And so it went as Neil Armstrong and Buzz Aldrin descended to the surface of the moon aboard the Lunar Module Eagle on July 20, 1969. The world heard communications between the crew and Mission Control live as they happened. But Earth did not hear the conversation between Armstrong and Aldrin, although it was recorded onboard the Eagle.
All of the Apollo spacecraft included onboard voice recorders, activated during much of each mission to record the crew's conversations. The transcripts of those recordings were publicly released in the mid-1970s and they have been posted on the Internet for years. But only recently were the actual onboard recordings from Apollo 11 digitized so that the recordings could be made available on the Internet.
The Apollo 11 Onboard Audio Tape Database cross references the tape numbers to the Mission Elapsed Time (MET) that was on each tape. The database includes a description of the mission status at that time. It is best to listen to the tapes while simultaneously viewing the same mission elapsed time on the transcript, since often the recordings are faint.
The digitized recordings are available here in the same form as they were recorded during the mission. As a result, they are noisy with technical interference that occurred during their recording and transmission. They are sometimes garbled and sometimes have long periods of no voice. They are not listed in chronological order but rather in the order that data was dumped onto storage tapes during the mission. A single tape may include recordings from several different periods of the mission.
The equipment onboard the Apollo Command Module that was used to make the recordings was called the Data Storage Equipment (DSE). Its contents were transmitted to the ground periodically during the mission. Also, the Command Module DSE had the capability to record data live during certain periods from the Lunar Module as it flew separately in lunar orbit. The equipment used aboard the Lunar Module to make the recordings was called the Data Storage Electronics Assembly (DSEA). It made recordings onboard the Lunar Module, but the DSEA flown on the Eagle during Apollo 11 malfunctioned. As a result, many of its recordings are barely, if at all, audible, with a constant high-pitched background tone. In the attached database, the recordings that are virtually inaudible are highlighted, but they are available on the web to ensure a complete release of the recordings made during the mission.
WASHINGTON (Reuters) - The original recordings of the first humans landing on the moon 40 years ago were erased and re-used, but newly restored copies of the original broadcast look even better, NASA officials said on Thursday.

The ongoing Lunar Laser Ranging Experiment measures the distance between the Earth and the Moon using laser ranging. Lasers on Earth are aimed at retroreflectors previously planted on the Moon and the time delay for the reflected light to return is determined. Since the speed of light is known with very high accuracy, the distance to the moon can be calculated. This distance has been measured with increasing accuracy for more than 35 years.
The distance continually changes for a number of reasons, but averages about 384,467 kilometers (238,897 miles).
The experiment was first made possible by a retroreflector array installed on July 21, 1969, by the crew of the Apollo 11. Two more retroreflector arrays left by the Apollo 14 and Apollo 15 missions have contributed to the experiment.
The unmanned Soviet Lunokhod 1 and Lunokhod 2 rovers carried smaller arrays. Reflected signals were initially received from Lunokhod 1, but no return signals have been detected since 1971, at least in part due to some uncertainty in its location on the Moon. Lunokhod 2's array continues to return signals to Earth.
The Apollo 15 array is three times the size of the arrays left by the two earlier Apollo missions. Its size made it the target of three-quarters of the sample measurements taken in the first 25 years of the experiment. Improvements in technology since then have resulted in greater use of the smaller arrays, by sites such as the McDonald Observatory and the OCA Laser-Lune telemetry station affiliated with the Côte d'Azur Observatory.
At the Moon's surface, the beam is only about 6.5 kilometers (four miles) wide and scientists liken the task of aiming the beam to using a rifle to hit a moving dime 3 kilometers (two miles) away. The reflected light is too weak to be seen with the human eye, but under good conditions, one photon will be received every few seconds (they can be identified as originating from the laser because the laser is highly monochromatic). This is one of the most precise distance measurements ever made, and is equivalent in accuracy to determining the distance between Los Angeles and New York to one hundredth of an inch. As of 2002 work is progressing on increasing the accuracy of the Earth-Moon measurements to near millimeter accuracy.
Some of the findings of this long-term experiment are:
-The moon is spiralling away from Earth at a rate of 38 mm per year.
-The moon probably has a liquid core of about 20% of the Moon's radius.
-The universal force of gravity is very stable. The experiments have put an upper limit on the change in Newton's gravitational constant G of less than 1 part in 1011 since 1969.
-The likelihood of any "Nordtvedt effect" (a composition-dependent differential acceleration of the Moon and Earth towards the Sun) has been ruled out to high precision, strongly supporting the validity of the Strong Equivalence Principle.
-Einstein's theory of gravity (the general theory of relativity) predicts the moon's orbit to within the accuracy of the laser ranging measurements.
Additionally, the accuracy of these experiments has improved historic knowledge of the Moon's orbit enough to permit timing of solar eclipses up to 3,400 years ago.
The presence of reflectors on the Moon has been used to rebut claims that the Apollo landings were faked. For example, the figure on the right shows evidence of something very small, located within a few kilometers of where a landing occurred, and which reflects laser light directly back to the source as well as a mirror array.

Of course this is terrific, unexpected news, but really, how on earth did they lose the tapes in the first place?
The skeptic in me will wait until I actually see the footage to believe this ridiculous saga.

If NASA does not come up with a very clear explanation on how footage from the most important event in recent History could go "lost" and wind up in some facility on the other side of the world, Im not buying this.
Does anyone know the official explanation for why and how this footage was supposed to have gone "lost"?
NASA's Lunar Reconnaissance Orbiter, or LRO, has returned its first imagery of the Apollo moon landing sites. The pictures show the Apollo missions' lunar module descent stages sitting on the moon's surface, as long shadows from a low sun angle make the modules' locations evident.
The Lunar Reconnaissance Orbiter Camera, or LROC, was able to image five of the six Apollo sites, with the remaining Apollo 12 site expected to be photographed in the coming weeks.
The satellite reached lunar orbit June 23 and captured the Apollo sites between July 11 and 15. Though it had been expected that LRO would be able to resolve the remnants of the Apollo mission, these first images came before the spacecraft reached its final mapping orbit. Future LROC images from these sites will have two to three times greater resolution.
