Day: July 19, 2009

In theory, it can happen to anyone recording moving images on tape or digital media: absent-mindedly or carelessly re-use the recording media, and thus lose the original content. If no copy exists, such an accident means an irrevocable loss.

But if the images were the most expensively shot in the whole of human history — literally costing billions of dollars and involving the genius and labour of half a million people over several years — we would expect these to be archived and preserved with great care, right?

Well, not necessarily — if the custodian is a government agency. On eve of the 40th anniversary of the first Moon landing by Apollo 11, the US space agency NASA dropped a bombshell: it admitted that the original recordings of that historic moment were accidentally erased years later.

One British newspaper called it “the scientific equivalent of recording an old episode of EastEnders over the prized video of your daughter’s wedding day”.

The loss became public when the Sydney Morning Herald broke the story in August 2096. “A desperate search has begun amid concerns the tapes will disintegrate to dust before they can be found,” it said.

While the media rushed with oops-style headlines like ‘One giant blunder for mankind’, NASA quietly investigated what really happened. Last week, they revealed the hard truth: the tapes were part of a batch of 200,000 that were degaussed – or magnetically erased — and re-used. It was a standard money-saving measure at NASA in those pre-digital days to reuse the 14-inch tape reels after several years in storage. Agency officials fear that the original Apollo 11 tapes were buried among an estimated 350,000 that were recycled in the 1970s and 1980s and the data was lost for ever.

But the historic visuals are not entirely lost: luckily, broadcasters who used NASA’s expensively obtained footage had archived their transmissions for posterity. For many months, NASA has worked with a leading digital imaging company in Hollywood to restore good copies of the Apollo 11 broadcast found in the archives of CBS News and some recordings called kinescopes found in film vaults at Johnson Space Center.

On 16 July 2009, NASA released the first glimpses of a complete digital make-over of the original landing footage that looked decidedly sharper and clearer than the blurry and grainy images of Neil Armstrong and Buzz Aldrin walking on the Moon.

And we have to admit, the new video is definitely better than the ones we’ve seen for 40 years!

The full set of recordings, being cleaned up by Burbank, California-based Lowry Digital, are to be released in September 2009.

I had often wondered why the original images from the Moon were so grainy: it wasn’t typical even for that time. And if NASA spent between US$ 22 to 25 billion on landing men on the Moon, surely they’d have harnessed the best available technology to capture and share their moments of triumph, I assumed.

Actually, the video coverage that was broadcast around the world — to an estimated audience of 500 to 750 million people — and has since been endlessly redistributed was not quite what came from the Moon. It was a diluted version. Stanley Lebar, the NASA engineer in charge of developing the lunar camera, now calls a “bastardized” version of the actual footage.

Here is the “as-it-happened” broadcast from CBS News that day, with the legendary Walter Cronkite anchoring to the biggest TV audience the world had known. (Footnote: You’ll see the first electronic “character generators” in use.)

The story is technically complex, but here’s the essence: live images from the Moon couldn’t be fed directly to the American TV networks using the NTSC broadcast standard. Audiences worldwide would be holding their breath that a delayed broadcast, even by a few minutes, would not have been as effective as ‘live from the Moon’. Under such time pressures, no conversions could be attempted. So a regular TV camera was pointed at the huge wall monitor at mission control in Houston.

This is known as kinescope, or telerecording: a recording of a television program made by filming the picture from a video monitor. That resulted in the grayish, blotchy images that everyone saw on their home TV sets. In other words, It was a copy of a copy, with significant quality losses in that process!

And what is now lost, permanently, are the tapes containing the original Slow-Scan Television (SSTV) tapes. Digitally remastering the CBS broadcast tapes is now offering us better images than we’ve been used to for 40 years, for sure, but they stem from an already adulterated source.

A new documentary, released in January 2009, offers new insights into one of the most challenging feats in international live broadcasting – how those images from the Moon were delivered to TV audiences around the world. Produced by Spacecraft Films and directed by Mark Gray Live from the Moon: The Story of Apollo Television

It tells how for the first time in history millions of people could share, in real time, the experience of frontier exploration.

“Placing a man on the moon and returning him safely to the Earth was hard enough in 1969,” says Gray. “‘Live From The Moon’ tells the story of how television, still a technological toddler, was developed for space flight, and examines the impact of the iconic passages that were returned.”

Here’s an excerpt from Space.com that reviewed the film:

To tell that story, Gray literally circled the Earth, shooting interviews at the deep space communication stations in California and Australia, as well as at space facilities and museums in Houston, Baltimore, Los Angeles, Princeton, Kennedy Space Center, Huntsville, Ala., Washington, DC and Weatherford, Oklahoma.

Along the way, he interviewed astronauts, flight directors, mission controllers, tracking station operators, historians and those who built the television cameras for the space program…. “Live from the Moon” is told with the insight of moonwalker Alan Bean; Apollo 10 commander Tom Stafford; flight director Chris Kraft; Neil Mason, who drove the Parkes Telescope; Westinghouse camera team leader Stan Lebar; and the voice of mission control Jack King, among others.

“Every single one of them believed that the TV was one of the most important legacies of Apollo. And many of them admitted candidly that they didn’t give the TV much thought during the actual missions,” recalled Gray.
