United Press International Photo 1969


This beautifully evocative vintage image, taken at Goddard Space Flight Center in Greenbelt, Maryland, is a United Press International photo, dated November 29, 1969. There's a candid immediacy to the scene depicted; it conveys a familiar sincerity and enthusiasm most of those who were teenagers captivated by model rocketry during the 1960s or 1970s (such as the author of this blog) will immediately remember.

It's fun to rummage visually through the details in this picture to discover items one is familiar with. The most obvious being the rockets, of course, such as the main body, clear payload section, and nose cone of a Centuri Payloader II in the grass, the Estes Astron Camroc camera nose cone in the boy's hand, or the Centuri (or Estes?) Apollo Little Joe II in the cardboard box at right. Next to the boy's left foot is a Centuri 1967 model rocketry products catalog, quite a collector's item today, all these years later.

The press text attached to the rear of the original photo reads as follows:

MODEL ROCKETRY

GREENBELT, MD: With the equipment and tools necessary to build a model rocket, a member of the National Association of Rocketry is busy assembling his latest creation. Each year, the NAR sanctions contests throughout the United States in preparation for the National Model Rocket championships, also sanctioned by the NAR. Model rockets are constructed of paper, balsa wood, and breakable plastics and contain no substantial metal parts. The rockets are powered by commercially manufactured propellants of proven reliability and performance.

Estes AstroCam 110 Conversion



I purchased my first Estes AstroCam 110 in July of 1980, at a toy store in Marina Del Rey, Los Angeles. At the time, obtaining photos taken from a flying model rocket wasn't a trivial matter; before the advent of widespread digital photography and advanced miniaturisation, it took considerable ingenuity and resources to achieve that goal. Moreover, by second half of the 1970s, Estes had decided to discontinue the earlier, somewhat cruder Camroc camera and the associated Camroc Carrier rocket, the only dedicated consumer model rocket camera.

We were thus delighted when Estes' 1979 catalogue announced the new AstroCam 110 camera (then sold with its dedicated Delta II carrier rocket). Rudimentary by today's standards, the AstroCam 110 still represented obvious technical progress when compared to the Camroc. It required manual advancement of the film after every picture taken, and it operated by means of primitive but relatively fail-safe system consisting of a simple spring-loaded shutter, triggered by a string trapped between camera and rocket body up to the point of parachute ejection.

Nonetheless, the AstroCam 110 was user-friendly and utilized a standard high-speed Kodak Kodacolor 110/ASA 400 colour film cartridge, and the resulting photos could be developed just about anywhere. We felt slightly disappointed, however, by the fact that the AstroCam 110 was a forward-looking device; we desired to take rearward-looking photos showing the rocket's fins and its smoke trail. It was obvious that a home-made conversion was required.

Years later, I thus modified at least one AstroCam 110 to such a rearward-looking configuration and launched it a number of times on a dedicated carrier rocket, Vehicle 71 (top photo), designed for C, D, and E motors. The conversion was not quite as simple an undertaking as I had hoped, as it required rethinking the triggering system. Taking into account the limitations of the pre-digital age and a mere model rocket as carrier vehicle, the results were very pleasing, however. This is evidenced, for example, by the launch and flight photos above, taken in northeast Switzerland, on June 17, 1999.
