There was a nice story recently about a recent restoration of that photo ...http://www.collectspace.com/news/news-111408a.html

I am amazed at times how my own past resurfaces.
One of my duties at Goldstone from 1974-1976 was to manage the tape backup for data received from spacecraft like the Voyagers and Pioneers that flew by Jupiter, Saturn (and the outer planets after my time), and other missions. It was sort of an unwanted task handed off on me. But I took it serious and devised a record system to keep track of when they were recorded and so they would be retained for the required time period. These were backups as the prime data had been transmitted to the mission scientist. These were held a minimum of 30-days in case of any bad data in the originals. I started stacking them in an unused office but in time they ended up in the climate-controlled "basement" of the 64m DSS-14 Control Building. They ended up being kept much longer than 30-days. I'm guessing these reel tapes were made by the same recorder as mentioned in the article. Isn't it fantastic that the old Lunar tapes were recoverable! 2009 will be my 30th anniversary of leaving Jet Propulsion Lab to move to Alaska...tempis fugit!
The, then new, Hydrogen Maser Master Clock was installed in this same room. It was used for precise timing of VLBI experiments, which previously required calibration by the famous "flying clock" or the x-band Moon Bounce timing system (ask Dick, K6HIJ). Not only Goldstone, but Madrid, and Canberra stations required to be on the same accurate time (ask Tom Clark about that).
As the New Year approaches we reflect on the past. Thanks to those who recently found those articles.
Merry Christmas and Happy New year! 73, Ed Cole - KL7UW (& Janet)
