The Importance of Digital Archiving

Ensuring the digital longevity of our scientific heritage is the ‘Giant Leap’ that we need to take.

The Apollo program, often cited as one of the greatest achievements in human history, was triggered by a soul stirring speech by the US President Late John F. Kennedy, on 25 May 1961. He set the nation’s mission for that decade as ‘landing a man on the Moon and returning him safely back to Earth’.

The first moon landing by Apollo 11 took place at 9.56 pm on Sunday, 20 July 1969 (Houston time) and Armstrong and Aldrin became the first humans to land on the moon. That ‘one small step for [a] man; one giant leap for mankind” was taken at 02:56 on Monday, 21 July 1969. Six hundred million people, or 1/5th of the mankind at that time, watched Neil Armstrong’s first steps on the moon.

The bandwidth for transmission from the moon was limited; voice, telemetry data, biomedical data and television had to share the link from the Lunar Module.  NASA budgeted only 500 KHz for TV from the moon surface, much less than the 4.5 MHz standard prescribed for commercial broadcast.  The video of the Apollo 11 was transmitted in narrowband non-standard Slow Scan Format (SSTV) -320 lines of resolution at 10 frames per second, instead of the US TV Standard of 525 lines at 30 frames per second.

The conversion from SSTV to Standard US TV format was achieved with the help of specially built scan converters and was simultaneously tracked at three stations, one in US (Goldstone) and two in Australia (Honeysuckle Creek and Parkes). In the scan conversion process, picture resolution, contrast, and brightness suffered, and extra system noise was introduced. The entire transmission was recorded on telemetry tapes.  The Parkes Station re-transmitted the transmission coming from the lunar module by microwave links to Sydney and relayed by Houston via satellite. The total transmission distance from the tracking stations to Houston was almost 50,000 miles / 80,000 km.

On 5 August 2006 NASA made a press release that jolted the world. The national dailies Sydney Morning Herald, the San-Diego Union Tribune, Voice of America, and the Washington Post carried headlines saying that ‘Just 37 years after Apollo11, it is feared that the magnetic tapes that recorded the first moon walk have gone missing at NASA’s Goddard Space Flight Centre (GSFC) in Maryland’. A desperate search began at NASA. Over 700 boxes of Apollo era magnetic tapes were returned to GSFC for permanent retention from the US National Archives by 1984. NASA is unable to trace these tapes of the Apollo 11 mission. NASA engineers fear that the missing tapes are in the danger of deteriorating into dust unless they are quickly found and converted to digital format. If found and digitized, they could produce unsurpassed quality video images of man’s first steps onto another world.

Will the world be lucky enough to finally see the moon’s surface almost as Neil Armstrong saw it? ‘It has a stark beauty of all its own. It’s like much of the high desert of the United States. It’s different, but it’s very pretty out here’. To quote Sarkissian, operations scientist at the Parkes observatory, ‘There will only ever be one first moon walk’.

To conclude, digital archiving of an enterprise’s heritage is an extremely important task that we should now seriously pursue. The missing tapes of the Apollo 11 mission is the best example to keep in front of us to work out serious strategies to protect our scientific heritage.
