great article but one omission in the mentioned time line of lunar
exploration.... The Hughes built Surveyor space craft that soft landed on the moon
and did photos. and the Russian Luna 9 (E-6 series), also known as Lunik 9
here is some info from wiki... some good tech specs of camera to get you
started..
I have a couple failed cable assemblies and a bad connector that was
imbedded and sawed and inspected from the Surveyor project.
I saw it built. I touched it though a glove.. I my brother and I hung out
with the Hughes crew that watched as many of these birds were shipped to
the cape from LAX
It was a great time to be a kid growing up!

mission.
Mission description
The Surveyor spacecraft was designed to attain the engineering objectives of
the Surveyor program, which included the first lunar soft landing by an
American spacecraft. No instrumentation was carried specifically for scientific
experiments, but considerable scientific information was obtained. The
spacecraft carried two television cameras - one for approach, which was not used,
and one for operations on the lunar surface. Over 100 engineering sensors were
on board. The television system transmitted pictures of the spacecraft
footpad and surrounding lunar terrain and surface materials. The spacecraft also
acquired data on the radar reflectivity of the lunar surface, bearing strength
of the lunar surface, and spacecraft temperatures for use in the analysis of
the lunar surface temperatures.
The spacecraft was launched May 30, 1966, directly into a lunar impact
trajectory. Engines were turned off at a height of 3.4 m above the lunar surface.
The spacecraft fell freely from this height, landing on the lunar surface on
June 2, 1966, in Oceanus Procellarum - 2.45 deg s latitude, 43.22 deg w
longitude (_selenographic coordinates_
(http://www.absoluteastronomy.com/topics/Selenographic_coordinates)

Earth....
). The spacecraft transmitted data from shortly after touchdown until July
14, 1966, with an interval of no operation during lunar night (June 14 to July
7, 1966). Engineering interrogations continued until January 7, 1967.
Science instruments
Television
The TV camera consisted of a vidicon tube, 25 and 100 mm focal length
lenses, shutter, filters, and iris mounted along an axis inclined approximately 16
deg to the central axis of the spacecraft. The camera was mounted under a
mirror that could be moved in azimuth and elevation. Camera operation was
totally dependent upon the receipt of the proper command structure from earth.
Frame by frame coverage of the lunar surface was obtained over 360 deg in azimuth
and from +40 deg above the plane normal to the camera Z axis to -65 deg
below this plane. Both 600 line and 200 line modes of operation were used. The
200 line mode transmitted over an omnidirectional antenna for the first 14
photos and scanned one frame every 61.8 seconds. The remaining transmissions were
of 600 line pictures over a directional antenna, and each frame was scanned
every 3.6 seconds. Each 200 line picture required 20 seconds for a complete
video transmission and utilized a bandwidth of 1.2 kHz. Each 600 line picture
required nominally 1 second to be read from the vidicon and required a 220
kHz bandwidth for transmission. The data transmissions were converted to a
standard television signal for closed circuit and public broadcast television.
The television images were displayed on earth on a slow scan monitor coated
with a long persistency phosphor. The persistency was selected to optimally
match the nominal maximum frame rate. One frame of TV identification was received
for each incoming TV frame and was displayed in real time at a rate
compatible with the incoming image. These data were recorded on a video magnetic tape
recorder. Over 10,000 pictures were taken by the Surveyor 1 camera before
lunar sunset on June 14, 1966. Included were wide and narrow angle panoramas,
focus ranging surveys, photometric surveys, special area surveys, and
celestial photography. The spacecraft responded to commands to activate the camera on
July 7 and, by July 14, 1966, returned nearly another 1000 frames.
Strain gauge
Strain gauges were mounted on each leg shock absorber to record the peak
axial forces at landing impact of the spacecraft. They were designed to accept a
force of approximately 800 _kgf_

on February 3, 1966, the four petals, which formed the spacecraft, opened
outward and stabilized the spacecraft on the lunar surface. Spring-controlled
antennas assumed operating positions, and the television camera rotating
mirror system, which operated by revolving and tilting, began a photographic
survey of the lunar environment. Seven radio sessions, totaling 8 hours and 5
minutes, were transmitted as were three series of TV pictures.
When assembled, the photographs provided a panoramic view of the nearby
lunar surface. The pictures included views of nearby rocks and of the horizon 1.4
km away from the spacecraft.
For unknown reasons, the pictures from Luna 9 were not released immediately
by the Soviet authorities. Instead, the Jodrell Bank Observatory, which was
monitoring the craft, noticed that the signal format used was identical to the
internationally-agreed system used by newspapers for transmitting pictures.

rushed a suitable receiver to the Observatory and the pictures from Luna 9
were decoded and published world-wide. The BBC reports speculation that the
spacecraft's designers deliberately fitted the probe with equipment that
conformed to the standard, specifically to enable reception of the pictures by
Jodrell Bank.
With this mission, the Soviets accomplished another spectacular first in the
space race, the first survivable landing of a humanmade object on another
celestial body. Luna 9 was the twelfth attempt at a soft-landing by the
Soviets; it was also the first deep space probe built by the _Lavochkin_

design bureau, which ultimately would design and build almost all Soviet
(and Russian) lunar and interplanetary spacecraft. All operations prior to
landing occurred without fault, and the 58-centimeter spheroid ALS capsule landed
on the Moon at 18:45:30 UT on 3 February 1966 west of the Reiner and Marius
craters in the Ocean of Storms (at 7°8' north latitude and 64°22' west
longitude). Approximately 5 minutes after touchdown, Luna 9 began transmitting data
to Earth, but it was 7 hours (after the Sun climbed to 7° elevation) before
the probe began sending the first of nine images (including five panoramas) of
the surface of the Moon.
These were the first images sent from the surface of another planetary body.
The radiation detector, the only scientific instrument on board, measured a
dosage of 30 millirads (0.3 _milligrays_

) per day . Perhaps the most important discovery of the mission was
determining that a foreign object would not simply sink into the lunar dust, that is,
that the ground could support a heavy lander. Last contact with the
spacecraft was at 22:55 UT on 6 February 1966.
