By James W. Young
retired astronomer from Table Mountain Observatory
A
very interesting transition image! As JPL pondered acquiring this
site for a permanent testing facility for solar cells
and panels, an immediate interest developed to begin some sort of optical astronomy
program. Ray Newburn, in the JPL Space Science Division, had been looking for a site to place
an optical telescope for planetary astronomy studies, and surveyed for a possible site at
Mount Wilson. However, the close proximity to the lights
from Los Angeles to Mount
Wilson was not acceptable. With the ongoing JPL solar cell/
panel testing in progress
at Table Mountain, this already developed site, with all utilities
installed, seemed like the perfect place! Newburn also had
recently acquired a 16-inch
'Nishimura' cassegrain
telescope from Biela
Observatories in Anaheim, CA for his needs. Ironically, the above image
shows that current testing facility in the background, while in the forground are the four pier
supports for Edson's 1940-41 20-inch telescope building for his Mars opposition
observations. This exact
spot was selected for JPL's new optical astronomy telescope Newburn had
already purchased!

Newburn then looked for a well
qualified experienced site astronomer/supervisor to watch the building, dome installation,
telescope assembly/installation, and then ultimately begin a synopyic planetary patrol of
Venus, Mars, Jupiter, and Saturn. He found such a man at the New Mexico State
University's campus in Las Cruces, New Mexico; Charles F. Capen.
Capen's qualifications included work at Lowell Observatory, a
field director at the Shiraz,
IRAN Smithsonian Baker-Nunn tracking station in the late 1950s, and
finally on staff at
New Mexico State University. Capen accepted Newburn's offer in
the Spring of 1962.
Since Smithsonian Institute was
leaving Table Mountain, JPL first needed to obtain a new
USFS permit to officially occupy and develop the site for its own use. 1962 USFS 'TERM SPECIAL USE
PERMIT'
Annual use permit for JPL cost
$250.
Smithsonian needed some sort of
legal compensation for their buildings, furnishings, and equipment remaining on
the site from JPL.
This is only page 1 of this companies appraisal document. Their
findings concluded that only
two of the old Smithsonian buildings had any furnishings of value,
therefore JPL offered, and
ultimately paid $12.000 to Smithsonian for that compensation.
With Charles Capen on site, a
new building for the 16-inch telescope began in June, 1962
Building construction, and the installation of a 16-foot Observa-DOME
The telescope was assmebled at
Table Mountain under the direction of both Newburn and Capen, then installed into the new building

The new telescope was ready for
its initial operations on August 1, which is known as 'First Light' (the very first
use of any newly installed telescope; either visually or by photography/photometry).
Newburn and Capen discussed hiring an assistant observer and darkroom technician.

At this same time, the author
was working at the NASA
Exhibit of the 1962 Seattle
World's Fair where several NASA technical people from various NASA facilities around
the country spent a few weeks assisting in the exhibit's
day-to-day operations. Their job was talk to the
public, and train all the young guides which I was one...in this case
the 'Lead Technical Guide'. One of these visiting NASA technical representatives was
from JPL; Thomas Bickler. Telling me JPL had just finished
building a new
observatory,
he suggested I should apply for a position there becasue he
already knew of my intense
interest in astronomy. I did so, and one week after the
Fair closed, JPL flew me down
to Pasadena for an job interview. I was hired and started work on
November 12, 1962.
I joined Chick, and the site's caretaker, Jack Lyon, after I moved down
to Wrightwood
from Seattle.

It is interesting to note here
that the same Tom Bickler who the author met at the Seattle World's Fair, sent a series of
pictures showing Bickler's involvement with JPL's solor work being done at Table Mountain,
along with the Hughes, EOS, Spectrolab, and Hoffman. He provided the author with a
series of pictures showing these other companies testing various pieces of their own equipment
around JPL's Mobile Solar Measurements Laboratory.
These images show the various
company's equipment and personnel that used Table Mountain to test their own solar cell
development between 1961 and 1963.
In 1964, and after JPL
negotiations with the USFS, a 1 1/2 million gallon water previously used tank, was brought to Table
Mountain, and constructed near the entrance to the facilty. This tank replaced the old aging
pimping station and low pressure gravity-fed water system Smithsonian installed back in
the late 1920s. This new tank also served as an entire water
service system for the needs of the local campgrounds, ski resort
facilities, and all other
local (mountain) organizational camps for youth groups.

JPL's Radio Science group, led
by Roland Carpenter, also took advantage of this new science site by having the assistant
residence building converted to a laboratory to house equipment for controlling an 8-foot
sub-millimeter wavelength dish mounted on a mobile trailer. There
were a series of tests made to calibrate the dish, and Table Mountain
became a new reliable
site for this science. From 1964 through 1965, radio science
measurements merited a larger
permanent installation of a new 16-foot dish. Calibrating the
16-footer required a bore site
facility, which after USFS approval, was located at Wright Mountain,
with a required minimum
separation of 4 miles. The following images show the
dishes, buildings, mounts, and the bore
site facility. For some unusual circumstance, after the necessary
calibration of the new dish
was completed, Wright Mountain suffered a major geological
slippage where the building bore
site building was located. Earl and the author retrieved all the
electronics from the building
after an initial slippage of about 20-feet. The building had
partially crumbled within another
year, so the building was destroyed. By the year 200, parts of
the remaining building were
no longer visible.

Despite specific needs of the
new optical astronomy telescope observations (dark skies, clean air, with no external heat waves
generated by nearby buildings), JPL's Thermionic's Division constructed a Butler building
just to the west of the 16-inch telescope facility to house their new solar concentrator and
tracker. This new facility opened in late 1963, and replaced the
old mobile solar trailer on site since the early 1960s.

building - 1963
During
the winter of 1963-64, Table Mountain had many feet of snowfall.
The new Butler building had internal heat to
keep all its electronics at 'room temperature'. This created a problem for the operations of
the 16-inch telescope...the heat waves generated by the Butler building caused
very poor astronomical 'seeing' for the optical astronomy operations.
It was around this time that the
two JPL science divisions needed an arbitrator to assess conflicts, and propose
solutions. A Table Mountain 'Steering Committee' was set up at the
end of 1963, especially to resolve this issue between the science and
thermionics divisions.
The new committe was composed of Johnny Stephen, Barney Huber, and
Jack Tallon. The
first issue they dealt with was to make Capen the 'Site Manager',
that gave him authority
to resolve local problems/conflicts...parking, visitors, firearms,
alcohol, etc. Negotiations
between the 2 divisions resulted in the thermionics division agreeing
to move its operations
to a yet undeveloped site one half mile east of the main Table Mountain
operations. A new
road was constructed around the north side of the current site, to the
new area about 100
feet lower in elevation. Also, at this time, Capen felt the need
to officially number each of
the buildings. With the initial construction of the optical
telescope building, the first of all
new JPL buildings, Capen numbered the telescope building as TM-1; the
thermionics building
became TM-2 (moved to its new site to the east), the two (combined)
bunkers were TM-3,
and so on, as noted in the map below after the new road
construction. JPL also built a new
Industrial Users Site, below the top of the mountain to the
south. Those many users could
now access their own site at any time with a locked gate. This is
shown in the last image.

of the main site. Notice the numbers of the various other
buildings. When the Butler building was moved east, a new section
was added at the same
time, now referred to as TM-14.
The Table Mountain 'Steering
Committee' soon realized with new site developments, roads, and building construction, Capen
was being overworked while his main job with the planetary astronomy program was being
seriously impacted by all the day-to-day site issues. It was decided to hire a full-time
'Site Manager' position. JPL found such a man, Earl Ivie, that already worked at their facility
in Pasadena. He agreed to the new position, and moved his residence to Wrightwood in early
1965.

It was obvious Ivie had been an excellent choice.
He had experience in so many areas!

Mr. Ivie then occupied TM-8, the
old Smithsonian bunk house, for a new Site Manager's office. Ivie spruced up
the site by have a marigold flower garden planted outide his door.
