"This is History"
Art Cosgrove is a Kodak retiree who worked first hand on the Lunar Orbiter program that photographed the moon in the late 60's to search for safe landing locations for the Apollo missions. Art was part of the Kodak team directly involved in this program, and was there when the first high-resolution images of the moon were received on Earth over 40 years ago. With last week's anniversary of the Apollo 11 lunar landing, I had an opportunity to talk to Art to learn more about the Lunar Orbiters - giving me the chance to have a conversation with someone who really did make history.

How were you involved in the Lunar Orbiter missions?
To answer that, it probably helps to explain how the Lunar Orbiter sent images of the moon to earth. It was a three-step process - first, images were captured by the orbiter's camera using film, the film was processed on-board the orbiter, and then the resulting images were scanned and transmitted to earth as a video signal. Kodak was responsible for the image data received from the orbiters, and provided video engineers to monitor this data as it was received. I was one of three video engineers working with this data as it was received by one of three Deep Space Network ground receiving stations on Earth - for the first Lunar Orbiter mission, I was at the receiving station in Australia, but also worked at the Spain and California stations for the other Orbiter missions.

You must have been one of the first people to actually see high-resolution images of the moon's surface - right?
I was - but not in the way you might think. Remember that the technology then was very different from what is available today - we weren't looking at an image displayed on a monitor, but a raw video signal being sent from the orbiter. This signal was sent directly to a film recorder, but I would also monitor it on an oscilloscope as it was being received in real time - a flat line was a smooth surface, while "bumps" in the trace corresponded to the edges of craters. So I could see right away what type of terrain the orbiter was looking at. After the signal was written to the film recorder, we would process the film and review it before sending it to Rochester - so I saw actual pictures of the moon's surface before almost anyone else, too. Because I saw these images before they were even sent to NASA, I ended up as one of the first people ever to see an image of the far side of the moon (the side that normally faces away from the Earth).
How did it feel when you saw the first signals from the first orbiter and knew that knew the entire system was working?
Man, it was exciting! Really, it's hard to describe the emotions, the pride of knowing that you're involved in this enormous undertaking. Here I was, a young kid right out of school, now spending 12 - 14 hours a day talking directly to the Jet Propulsion Laboratory as these pictures came in. Knowing that you have a part - a major part - in this, was amazing. There were certainly other parts of my career where I was excited about the work I was doing, but I never had the level of intensity that I had with this program. It was a very exciting time in my life, where I was seeing the world, experiencing new cultures - and being a part of this historic undertaking.

Did you appreciate that you were involved in something historic?
Absolutely. The Lunar Orbiters were considered part of the Apollo program, and everyone understood the importance and significance of that entire effort. My personal sense was "this is history" - and I was not only living it, but playing a key part in it.
About two years after the last Lunar Orbiter mission, Apollo 11 left the Earth heading for a lunar landing on Tranquility Base - a location that was finalized in a large part based on the information collected by the Lunar Orbiters. Were you worried about that - did you think that you had collected was good data?
We definitely thought that data from the Orbiters was good. The images we collected looked pristine, and we had a lot of them.
How important do you think Kodak was in preparing for the Apollo landings?
There really was no one else that could have developed the technology that ended up in the Lunar Orbiters. Kodak had a lot of unique experience working in systems for aerial reconnaissance (of the Earth), and the Lunar Orbiters were build on the shoulders of that technology. For example - on an extended space mission, you have to deal with the potential impact of high radiation levels on film. At that time, no one really knew what those actual effects would be, but Kodak had physicists who had a lot of experience working film, and who were very good at hypothesizing about what would happen in space. That experience was inside Kodak, and was vital to the successful design of the Orbiter.

What are you doing now?
Keeping very busy! I retired in early 2006 after over 40 years at Kodak. During my last years at Kodak, I represented Kodak on several committees defining broadcast standards for digital TV and digital cinema, and I still monitor those activities. I've also been doing some personal travel - my wife and I have spent the last two winters in Florida Keys, and this past spring we travelled to Iceland and took a cruise on the Baltic Sea.

Comment: Hi Art, Well I only worked with you in the days of Cineon and Kodak Digital Cinema, but I might have guessed you would have had an "over the moon" experience somewhere in your illustrious career. What a great article and illustration of how such cumbersome technology from today's perspective was able to contribute to the astonishing success story of lunar landings. Next time you are in Europe, let us know!

Comment: Hi Art, it's been many months since we had lunch together in Exeter, NH. Didn't know all the back ground on your early career with Kodak. My memory goes back when you and I were on "the Cheers Set" testing a new film. Thanks Alan for the picture of Art! Cheers, Jack
