The
new vision for lunar exploration, as articulated by President Bush,
demands the design and construction of an entirely new architecture
of lunar hardware. Almost fifty years ago any possibility of keeping
the now legendary Apollo/Saturn infrastructure intact, was doomed by
political infighting between the Army and the Air Force. In fact,
NASA’s lunar hardware may well have been on a path to oblivion
before it had even been built.
In
1950 a group of scientists had proposed a global study of the Earth
and its resources. It was to be known as the International
Geophysical Year and it would run from July of 1957 to December of
1958. Both America and the Soviet Union committed resources and money
to this ambitious project and both stated their intentions to launch
an earth-orbiting satellite during the IGY to assist in the global
research. The American science community, with the approval of the
White House, made the decision that America’s first satellite would
be completely divorced from the military. An untested missile
proposed by the Navy would be used to carry the Vanguard civilian
satellite.
Wernher
von Braun had been discussing his plans with the Army since 1954 and
he knew that he could almost certainly accomplish a satellite launch
with the proposed upgrades to his Redstone missile; but the funding
was constantly in question. In September of 1956 he launched a
Redstone/Jupiter C (Missile 27) but was told that he was not to add
the extra propellant that might have pushed its payload into orbit,
instead the tank was filled with sand.
The
Army wanted von Braun to launch a satellite with Redstone but the
Eisenhower administration wanted nothing to do with the potential
militarization of space. Meanwhile, the Air Force were pitching their
untried Atlas ICBM as a satellite launcher, while simultaneously
pitching the proposed Thor missile as the best choice for America’s
medium range defense. The stakes were incredibly high, whoever was
given the funding to build a missile to launch a satellite would have
a huge advantage when it came to snatching the real prize: the
control of America’s missile forces.
General
Bruce Medaris ran the Army operation out of Huntsville, Alabama. At
the end of the war it had been the Army who had ensnared von Braun
and his team, and few would argue that they were the world’s
leading group of rocket scientists. But the Army’s main political
clout resided with contractors like Chrysler in Detroit. On the other
side of this feud was the Air Force team led by Bernard Schriever.
His political support came from the aerospace industry, Boeing,
McDonnell, Grumman and the dozens of other smaller aircraft
manufacturers. Both Medaris and Schriever knew that missiles
represented the wave of the future, and that the government would not
be able to afford two independent missile programs. Inevitably a
rancorous situation erupted between the two services over this plum
assignment. While Schriever found it difficult to convince Washington
that the Air Force was better equipped than von Braun’s team to
launch an American satellite, he still managed to divert enough
political and fiscal capital away from Huntsville to keep the Air
Force in the running until the Atlas and Thor missiles were brought
up to speed.
A
pivotal moment occurred in July of 1958 when America’s civilian
space agency, NASA, was brought into existence to take care of the
nation’s space program. Almost immediately NASA approached Medaris
and asked if the Army would be willing to turn over the cream of
their rocket team to the civilian agency. Medaris and von Braun were
dead-set against breaking up the organization of nearly 4000
rocketeers based in Alabama, and rebuffed the NASA invitation. This
decision was a watershed moment because it permanently took the
potential lead in America’s space program away from the Huntsville
team and opened up the doors for Houston and Langley to take over.
Medaris
and von Braun continued to work on improving America’s missile
program and to that end the trusty Redstone was soon to evolve into
the Juno and the Jupiter, before von Braun would propose, in
September 1958, a gigantic booster called the Juno V. This
super-booster would be comprised of several Redstones strapped
together and its proposed payload would be the Air Force’s orbital
bomber the X-20 Dyna-Soar. To mount the Dyna-Soar onto the Juno V
would require a powerful second stage and the Air Force had already
suggested that their new Titan booster would be perfect for the job.
The
problem with this proposal was that no one knew exactly what the
Dyna-Soar’s mission would be. At one point it was to be a
suborbital recon vehicle, then it was upgraded to a suborbital
bomber, before it was decided it should be a fully-functioning
orbital weapons’ platform. During the course of this relentless
upgrading the Juno V was renamed the Saturn and the tooling and
design work were set in place to accommodate the Titan I as the
second stage.
However,
when Schriever and the Air Force upgraded the Dyna-Soar for the
umpteenth time it was decided that the more powerful Titan II would
now be needed for the second stage. This simple decision, made by the
DOD and the Air Force, caused a huge problem for von Braun and the
Army. Retooling the Saturn to accommodate the Titan II would mean
changing the diameter of the Saturn. This presented a very difficult
and expensive problem for Medaris and von Braun.
Medaris
saw this as a ploy to force the Army out of the missile business
because he knew he would have to go back to the DOD and ask for a
sizeable increase in the Saturn budget to meet the Air Force’s new
specifications. As soon as he made this request,
Schriever
was standing by with a counter proposal; to use an unbuilt and
untested Air Force missile to be dubbed the Titan IIIC.
Medaris
saw this as a transparent political maneuver to push the Army out of
the missile business, but he could do nothing but stand and watch as
the Air Force pulled away with the money and the go-ahead to take
over the booster program for Dyna-Soar. This regrettable situation
left the Army holding 4000 rocket engineers, a gigantic booster
program with no payload, and nowhere to turn. Medaris offered von
Braun his choice, to either go and work for the Air Force or to
approach NASA to see if they might still be interested.
At
first NASA expressed little interest in bringing the massive
Huntsville team onto its payroll but then something extraordinary
happened; President Kennedy announced that America was going to the
moon within nine years. This grand task would fall to NASA, which at
the time had exactly fifteen minutes of spaceflight experience and
only a fraction of the infrastructure necessary to accomplish such a
program. Suddenly, von Braun’s super-booster began to look
extremely attractive. It was already half built, most of the R &
D had been paid for by the Army and there was no contesting the value
of the team of engineers who were now virtually sitting in political
limbo.
In
July of 1960 Medaris and the US Army handed over their prime Saturn
missile program to NASA. The NASA administrator inherited the Saturn
at virtually no charge, along with the best missile research team in
America. As an added bonus NASA was also given the Army’s prime
satellite team at the Jet Propulsion Laboratory, and a huge parcel of
land and infrastructure in Alabama, soon to be known as the George C.
Marshall Space Flight Center.
Saturn
was no longer a weapon, so now the money began to flow into von
Braun’s department from NASA. The extra money freed up at the DOD
was pumped into the Air Force’s Dyna-Soar and Titan programs and
for a time everyone was happy, except Medaris, who perhaps rightly
felt like he and the Army had just been robbed.
Unfortunately,
it could be argued that this set the stage for the dismantling of the
Saturn program before it had barely even started. Saturn had begun
life as a heavy-lift military launch vehicle, built by the team who
had competed for the country’s missile program and lost, and then
it was converted into a civilian launch program with no immediate
future beyond the end of the decade. The Army relinquished the
missile business to the Air Force and von Braun’s team headed into
what must surely be one of the most amazing decades of research and
development the world has ever seen; but his team now only existed
for an end-goal that was less than ten years away. Ironically the
Dyna-Soar program would be cancelled in late 1963.
Both
von Braun and the Air Force had wanted to go to the moon long before
President Kennedy made his decree. In December of 1958 von Braun had
pitched a military lunar base to Washington called Project Horizon.
It was to have used a massive 12 million pound booster and would have
been able to carry as many as 16 people into low earth orbit. The Air
Force had also started their own lunar base proposals back in the
late 1950’s under the name Project Lunex. Needless to say, both of
these military moon bases were to have been audacious and expensive.
From
1958 to 1962 all of the proposals under consideration involved
building very large boosters to send very large spacecraft directly
to the lunar surface. This was known as Lunar Direct and the only way
to pull off such a mission was to build a gigantic booster. This may
have been a deliberate choice by the Air Force and Army teams since
they wanted to establish a permanent presence on the lunar surface.
When NASA came into the picture and were told to just “get there
and back” within nine and a half years, and not to worry too much
about staying very long, the von Braun team, along with the rest of
NASA’s very capable engineers had to take a long hard look at how
to achieve this goal, with less money and less time.
It
soon became apparent that NASA was not going to have the benefit of
the Pentagon’s deep pockets, and that NASA’s budget was going to
be constantly held under close scrutiny, since it sat on the same
appropriations ticket as the Housing and Urban Development budget.
This would be a curse for NASA for years to come. Every time the NASA
budget came under discussion the pundits would compare space
exploration with housing for poor people. Undoubtedly if NASA had
been put on the agriculture budget it would never have been mentioned
in the same breath as HUD, but would have been held hostage to crop
yields.
To
accommodate the President’s very short time frame, and to do it
within the confines of a limited budget, NASA’s engineers opted to
resurrect an idea first proposed in 1938 by H.E. Ross of the British
Interplanetary Society Committee. Ross had figured that if you wanted
to land on the moon it made more sense to leave your return fuel in
lunar orbit while you went on a lunar excursion. In the summer of
1962 NASA adopted this technique known as Lunar Orbit Rendezvous. It
involved leaving part of the spacecraft in lunar orbit while an
independent modular lander was sent down to the surface. From that
point forward NASA began to develop a totally separate lunar landing
craft.
Boeing,
Convair, GE, Bendix, Martin and many others had tried their hand at
building a spacecraft that could fly straight to the moon but it
would be Grumman that would ultimately get the coveted contract for
the modular lunar lander in November of 1962. The orbiting
mothership, known as the command and service modules, would be built
by North American Aircraft at their Downey, California factory. In a
remarkably short period of time the lunar module would evolve from
its early NASA designs, in the Spring of 1962, to its almost final
configuration in 1968.
As
early as 1961 there were people working in industry, and at NASA, who
realized that the race to the moon was to be a short-lived
experiment. To try and forestall the demise of Apollo, North American
began offering up derivatives for their Apollo Command and Service
Modules that could be used for everything from orbital ferries to
reusable shuttles. Simultaneously, Grumman began planning an entire
array of modifications to the lunar module that they hoped would see
their spacecraft live on into the 21st century as everything from a
space telescope platform to a full-fledged lunar base known as the
SLAMB. LM ascent stages could be used for rescue vehicles, while
descent stages could be used as trucking platforms. The LM that
finally took Neil Armstrong and Buzz Aldrin to the moon in July 1969
had a maximum payload capacity of 300 pounds, but a slightly modified
Grumman LM descent stage, using a series of augmentations, would have
been capable of delivering 12,000 pounds to the lunar surface.
Not
to be left out of this competition Boeing, working in consort with
General Motors, proposed a complex series of lunar base modules known
as LESA; also designed to be launched on the Saturn V. The LESA
modules were expandable and would have been supported by a dizzying
array of surface vehicles, ranging from lunar fork-lifts to hovering
flight indexers. The Bendix corporation responded with a fully
realized series of plans, known as MOBEV, that would have delivered
an assortment of mobile lunar laboratories to the surface, while the
Bell Aerospace Company, of Buffalo New York, studied, built and
tested a host of flying vehicles that could be used for anything from
simple recon to emergency return-to-orbit.
The
overall complexity of these plans for the long term exploration and
inhabitation of the moon is at once inspiring and depressing. There
can be little doubt that given the necessary resources NASA would now
have fully-fledged lunar bases in constant use today. The Saturn V
was so flexible it could have been used to deliver two lunar modules
at once, or even massive logistics vehicles, to be manned by up to 18
people for months at a time.
Sadly
none of this was to be, because the Saturn had been born out of
military need, and had then come within a whisker of being cancelled,
before President Kennedy called it to glory in May of 1961. That
exhortation bore bitter fruit. It was a heart-transplant for Saturn
that shifted the massive booster from military service to civilian
duty and breathed a decade of life into the monster before consigning
it and all of its potential progeny to oblivion.
It
may be too much to hope that the new lunar spacecraft will not become
a political football like Apollo. However, since the moon holds
little interest for the US military, and NASA controls almost all of
the reins of America’s space program, perhaps this time we might
see a more robust vision for lunar exploration. A more measured and
long-term plan that won’t fall victim to who-controls-what-portion
of the taxpayers’ dollars.
Today,
the contractor community is much more consolidated than it was fifty
years ago, and the various armed services are much more settled in
their alotted roles. Fifty years ago the Army was still chafing at
the very notion of a separate Air Force. The political conditions are
simpler today, and this time we have history on our side. We know it
can be done, and we know how to do it. We have fifty years of
experience in space, and the benefit of billions of dollars of
research to build upon.
There
are those who believe that it will cost one trillion
dollars
to go to Mars. This number has such a nice ring that it is now even
being quoted by Presidential hopefuls. Some are even saying it will
cost a trillion dollars just to go back to the moon. This is a
preposterous claim and yet few in the media ever challenge these
ridiculous numbers. At today’s funding levels, without a single
dime of an increase, one trillion dollars would last NASA for 61
years. In fact, allowing for inflation and converting into 2007
dollars, we can see that NASA’s entire
budget
since its creation has been only $836 billion. That includes
everything: building mission control, the Apollo moon landings, the
Shuttle landing strip on Easter Island; everything.
The
truth is that between 1961 and 1975 NASA’s annual budget average
was just under $21 billion (in 2007 dollars). That’s a 22% increase
over today’s levels; but that included all of the R & D, the
infrastructure and all
the programs.
Most of the infrastructure is still intact and yet there are some who
say it would cost more to do it a second time than it did the first
time. A vast sum of money has already been spent on studying the best
way to explore space. Reams of research have been generated and then
ultimately shuffled off to the national archives to languish.
Brilliant ideas sit side-by-side with thoroughly explored dead-ends.
Both are equally valuable, but if we choose to ignore the past we may
as well have burned that $836 billion.
In
my Lunar
Exploration Scrapbook (ISBN
978-1894959-69-8) I have gathered many of Saturn’s lost offspring
and placed them side-by-side with their even stranger lost cousins.
From the British Interplanetary Society’s original pre-war designs
for a lunar lander to the massive nuclear habitats of the late 1960s;
from the seeds of the rocket belt (born of rocket propelled
snow-skis) through to nuclear lunar tricycles; my book contains fully
texture-mapped color computer renderings of hundreds of unrealized
possibilities from the archives of America’s golden era of space
exploration, a glimpse of what might have been and what may yet be.
