the Boeing proposal carried the highest price tag, it clearly met or exceeded all of the
requirements for the lunar mission. and the evaluation board selected it over the other
competitors. On 20 December 1963 NASA Administrator James E. Webb announced
selection of the Boeing proposal and, after Congress accepted the decision, an incentive
contract was signed with the firm in April 1964.

Whether members of NASA’s source evaluation board knew of the Eastman
Kodak camera’s association with the classified National Reconnaissance Office is
uncertain, but they surely became aware of its military origins as a component of the
earlier Air Force satellite reconnaissance program. Whatever their understanding of its
clandestine background in 1963, the mix of proven technology and extraordinary efforts
of NASA and Boeing-Eastman personnel brought the space and ground segments quickly
on line. The space agency
launched five of the “SAMOS
Lunar Oprbiters” successfully
between August 1966 and
August 1967. Now equipped

Instead of representing an abject failure, SAMOS secretly helped make possible
manned lunar exploration and it became the nation’s first near real time film imaging
system in space. The NRO’s electro-optical imaging system that followed in the 1970s
was, to be sure, the wave of the future: it became the first near real time digital imaging
system. But, as near real time myths go, it ran second to an earlier NRO contribution to

In the fall of 1963 a NASA Source Evaluation Board examined five proposals
received from aerospace firms for the Lunar Orbiter, including the Boeing entrant. Board
members found the other four proposals employed liquid film developing (difficult to
contain in the hard vacuum of space), high speed film sensitive to solar radiation, and
single lens camera designs that required development and testing to prove their operation
in space. The Boeing/Eastman Kodak proposal featured a semi-dry film developing
process, low speed film that required minimal shielding from solar radiation, and a twin

lens camera along with much other equipment already developed and available. Although

SAMOS TO THE MOON:

The Clandestine Transfer of Reconnaissance Technology
Between Federal Agencies

R. Cargill Hall

Among those who share a passing interest in the history of astronautics, two

popular myths remain in vogue. The first contends that the U.S. Air Force, which began

American work on reconnaissance satellites with the SAMOS Project, failed in the late

1950s in its efforts to create a near real time film imaging system. Second, and entirely

dependent on the first
axiom, the electro-optical
imaging system developed
later by the National
Reconnaissance Office
(NRO) represents the first
application of near real time
satellite imaging. The actual
story, as you might suppose
at this point, is rather
different.

Conceived in the
mid-1950s. the —_— novel
SAMOS imaging system at
that time represented cutting
edge technology—a near
real time analog film-
readout satellite. The

built the E-1 (preliminary) and
E-2 (advanced) payloads. The
E-1 featured a six-inch focal
length lens in a camera that
spooled a _ special two-
component EKC Bimat
(positive) film, and SO-243
(negative) film. The exposed

negative film, converged with

the gelatin-coated SO-111

Photograph counesy FEKC  Bimmat film, was developed in a

SAMOS-Lunar Orbiter Camera with Lenses Installed semi-dry chemical process, and
then was scanned by a Columbia Broadcasting System flying spot line-scanner that
consisted of a cathode-ray tube and a rotating anode having a high intensity spot of light.
A photomultiplier converted the light passing from the scanner through the film into an
electrical signal whose strength varied with the density of the emulsion layer of the film.
The images were then radioed to Earth as frequency-modulated analog signals, to be
assembled much in the manner of a wire photo, each image built up in swaths.

Judging SAMOS a national asset like the U-2, and one that ought not be directed
by a military service, in late August 1960 President Dwight D. Eisenhower removed
SAMOS from the contro! of the regular Air Force and assigned it to a new civilian office
in the Department of Defense. A small contingent of Air Force officers and civilians
responsible for SAMOS now reported to the director of the new office, Under Secretary
of the Air Force Joseph V. Charyk. But, when launched into a low-Earth orbit in late
1960 and early 1961, SAMOS E-1 imaging payloads encountered problems—and not just
the normal ones associated with electronic component or launch vehicle malfunctions.
Like the CORONA Project that recovered film capsules, the E-1 readout payload also
was a film-limited system and did not have a long life on orbit. Second, it had no image
storage and recall capability, and had to transmit its take to a ground station on the next
pass. Third, the images were not encoded; for security reasons that meant the film had to

be read-out over the continental United States. Finally, SAMOS, operating at a

Megahertz and in view of a

minutes as it passed overhead,
would lose part of its
reconnaissance take on each
revolution. In September

CORONA and the other film recovery satellite systems then under development.

Having acquired, launched, and then terminated work on a near real time imaging
satellite, however, NRO officials at that time agreed to consign the SAMOS imaging
system to the National Aeronautics and Space Administration (NASA) for use in its deep
space exploration program. The surreptitious transfer of this technology, a fact just
recently declassified, has remained unknown to many in the NRO and NASA because of
the compartmented security measures then in place. It occurred in the following manner.

When in the summer of 1963 NASA requested proposals for a five flight Lunar
Orbiter imaging satellite, the Eastman Kodak Company asked for and received
permission from the NRO to join The Boeing Airplane Company and bid on the program.
In the effort to meet NASA requirements, Eastman would modify its E-1 camera with an
80mm focal length Schneider-Xenotar lens and an off-the-shelf 24-inch telephoto lens
procured from Pacific Optical. The two lenses would be bore sighted at the surface of the
moon for a planned orbit of about 30 miles altitude. Light would pass through each lens
to the film, but the simultaneous images were interspersed with other exposures, and not

placed side by side. The camera employed the existing velocity over height sensor to
