II) Procellarum
BaseMoonlab I launched in the wake
of the first Soviet moon landing. On April 12, 1974, Alexi Leonov touched down
at Mare Nubium. Leonov spent barely six hours on the surface before returning to
Soyuz 14. Unlike Apollo, the Soviets used own two cosmonauts per mission; one
venturing down to the surface in the smaller Soviet LM, while the other remained
in orbit. Leonov returned to the Soviet Union with twenty-two kilograms of
regolith and rocks, far more than all the sample return probes
combined.
Unlike Neil Armstrong and
Edwin “Buzz” Aldwin, Leonov did not have the world’s spot light cast upon him.
He received the expected hero’s parade in Moscow, and was praised by the Soviet
press as well as the presses of her vassals, but the only mention in American
media was a brief mention of his landing on CBS Nightly News as well as various
newspapers. There was a little concern voiced about what would happen if
astronauts and cosmonauts were on the moon at the same time, but this was
quickly silenced upon it was explained that the moon was a rather large
place.
Preparations for Moonlab I
continued through the spring of 1974, and the countdown to the first Moonlab
launch proceeded much swifter than the countdown leading to Apollo VIII. The
Saturn V flew with a near perfect record with the only malfunction being an
engine in the first stage of Apollo XIII. NASA’s engineering team was confident
that the Saturn Vb would prove just as reliable. This did not stop flight
director Gene Krantz, or any other watchmen at mission control in Houston from
sweeting. The Saturn V never failed, but with the amount of fuel it carried, it
would take only one failure to obliterate a good portion of Cape Canaveral. A
similar incident nearly happened with the Soviet’s N-1 rocket, and only a
last-minute automated abort prevented it from wiping out their lunar
ambitions.
Launch was scheduled for
July 4, 1974, which brought mixed feelings from Mission Control. While the
Fourth of July was all about launching rockets into the air, those rockets
always exploded in dazzling displays. The NASA family was a rather superstitious
lot, and worried such analogies would jinx Moonlab I. Their fears were
unfounded, for in the morning of July 4, Moonlab I left Florida without a hitch.
Real trouble did not occur until July 9, when Moonlab I prepared for its
automated landing.
Glitches in the
lab’s computer did not occur until after the landing sequence was initiated,
thus well past the cancellation report. Engineers rushed frantically to solve
the problem, uncertain if the problem were real or if one of Moonlab’s thousands
of sensors was faulty. It would not be the first time a mission was placed in
jeopardy because of a faulty indicator. Such incidents dated back to John
Glenn’s flight, when a faulty sensor told Mission Control that his capsule’s
heat shield may be loose. In the case of Moonlab, the sensor in question relayed
data back to Houston indicating a dangerous list in the descending
HM.
A second sensor gave a more
positive report. It reported the HM descending normally and all systems green.
Mission Control had to choose which sensor to believe. Redundancies in the HM’s
landing program should automatically correct any list. Since no change was
detected in the landing, either there was no list, or the software was also
malfunctioning. The Moonlab engineering team insisted it was far more likely
that the first sensor was malfunctioning than the second one as well as the
landing program. Had they decided otherwise, Mission Control could have sent
orders to Moonlab to change its trajectory, but remotely operating a landing
vehicle with a 2.6 second lag was challenging at best.
Krantz gave the OK for the HM to continue its flight
plan, allowing Moonlab I to touch down in the middle of the Ocean of Storms at
1404 on July 9, 1974. The experience was nowhere near as hair-raising as the
Apollo XI landing, but it was enough to give the flight controllers a few more
gray hairs. Moonlab II, the first of several supply missions, launched on
September 12, landing less than a kilometer from the HM five days later. Along
with a year’s supply of food, water and oxygen, Moonlab II also included the
moon buggy. The mission ended without as much as a glitch in the system. It was
almost too perfect for NASA, leaving high level players in Project Moonlab
apprehensive about the third mission.
Unlike the two previous missions, Moonlab III would be
manned. The mission would take three astronauts to the moon for a six month
visit. It would be the first mission to leave a C/SM in orbit around the moon
unmanned, virtually stranding the crew on another world. Earlier unmanned Earth
orbital tests of the Block III Apollo proved it could remain dormant for up to a
year, and be brought back to life without a major problem. All the hardware was
proven and designs sound. Whether the capsule would actually awaken after its
hibernation, the crew would not know for six months after reaching the surface.
If not— contingency plans for a rescue mission were proposed, but by the time
the spacecraft could be readied, launched and at the moon, supplies in the LM
would have been exhausted.
A misfired
Apollo was not the only emergency concern of the mission, though it ranked high.
Six months on the moon was enough time for the health of any astronaut to
decline. One concern was a sudden onset of appenticidits. With astronauts, being
a tough a macho lot, NASA doctors feared that by the time they complained about
abdominal pain, the three day return trip might be too long to save the crewman.
There was some discussion about preventative surgery, removing the appendix
before the astronauts left Earth. For something as long as a Mars mission, it
would be a must, but the moon was close enough for alternatives. Moonlab was
stocked with emergency antibiotics and other drugs. At the first sign of serious
complications, these medicines could be administered before an immediate abort
of the mission.
Each of the
astronauts for Project Moonlab underwent basic field medicine. The vacuum of the
lunar surface was a deadly environment even under the best of conditions. Odds
were, that sometime during one of the six month plus missions, one of the
astronauts would suffer injury. Astronauts underwent similar training regiments
as Army corpsmen, including setting bones and patching wounds. Some of the
training was more for a psychological benefit, for if an astronaut’s body
received injury great enough to cause bleeding out on the surface then their
suit was probably already punctured. Any injury serious enough to require
doctors on Earth to talk the astronauts through would result in an immediate
mission abort.
To command Moonlab
III, NASA turned to one its more experienced moon hands, James Lovell. Lovell
visited the moon twice during Apollo; first with the first trip to the moon on
Apollo VIII and later for a landing on the Frau Mauru Highlands on Apollo XIII.
Lovell intended to retire from NASA following Apollo XIII, but many in
management and mission planning, including long time boss Donald Slayton,
convinced Lovell to stay on for one more mission. He agreed, “as long as I don’t
have to go with Frank again.” The Frank he referred to was Frank Borman, fellow
astronaut, partner on Gemini VII and Apollo VIII, and good friend. Bormann
retired from the program not long after Apollo VIII.
NASA would draw upon its experienced Apollo crewmen to
command all of the Moonlab missions, with all commanders having already once
walked on the moon. For pilot, NASA tapped Apollo XVI LM pilot Charles Duke, who
has even more time on the surface than Lovell. The role of C/SM pilot would be a
short one for all Moonlab missions, and all pilots would find their mission
parameters to be broad and vague. Most of his time on the surface would be spent
operating the moon buggy, attending experiments and assisting the mission
specialists.
The first mission
specialist of Moonlab was geologist Harrison Schmidt. The Science Corps
astronauts were the envy of their fields. Unlike so many other geologists around
the world, who would study lunar samples in ultra-clean laboratories, Moonlab
scientists would get the chance to study the samples in their natural
environment. Initial studies showed high amounts of light elements in the
regolith and a low heavy metal content, disproving the co-accretion hypothesis.
The moon also lacked volatiles, gases like nitrogen, carbon dioxide, etc. though
its rock contained a great many of oxides. If a source of hydrogen could be
found, then water could be produced on the moon, cutting back on the cost of
supply missions.
Moonlab III sat on
the launch pad in the early morning light of December 6, 1974. It was a chilly
day at the Cape, though not so cold as to threaten any of the thousands of parts
of the Saturn Vb. The only company the three astronauts had as they climbed the
tower and entered the capsule were a few technicians who were eager to get as
far away from the two thousand tonnes worth of high explosives that was the
Saturn Vb as possible. Each Saturn launch cost far greater than any other
booster, for unlike the Titans and Atlases that carried nuclear warheads, if one
of the Saturn V family were to explode, it would have the yield of a small atom
bomb. NASA could not afford to have a single Saturn explode on the ground.
Should that happen, the manned space program would be shut down for an
undetermined length of time.
At 1005,
Moonlab III cleared the launch tower and began its three day voyage to the moon.
Unlike other missions, the weightless period of Moonlab III did not give any of
the astronauts space sickness. The lack of gravity has an adverse effect on the
stomach, and half of the people to ever travel in space suffered from it while
acclimatizing. After the third stage cleared Earth orbit and slid into a
trans-lunar injection, the C/SM separated and deployed its solar panels before
turning around and docking with the LM. Even after factoring in a third man for
the landing, the Moonlab LM proved far more spacious than its
ancestor.
Moonlab III entered lunar
orbit on December 9, only slightly of course. A minor correction in orbit
brought the spacecraft over the Moonlab HM by the sixth orbit. By the eighth
orbit, it was time to land. Moonlab III’s crew had a long hike across the barren
lunar wilderness to reach the HM. To avoid any possibly collision, Moonlab
standard operating procedures called for LMs to touch down at least
one-point-six kilometers (one mile) from the Habitat Module. The SOP applies to
both manned and unmanned landings. After reaching the surface and hiking to the
first supply lander, the crew unpacked the moon buggy and loaded it with as many
supplies from the cargo module. Weekly schedules called for one run on the
supply lander.
After spending their
careers in Gemini and Apollo Command/Service Modules, as well as Lunar Excursion
Modules, the HM was almost luxurious. In camping terms, the previous craft were
tents while the HM was an RV by comparison. Comparisons aside, living in Moonlab
would be no mere camping trip. Much of the time spent awake would either be
spent outside or on experiments indoors. The latter was saved for the lunar
night, when temperatures dropped well below -200 degrees. Environmental suits
were designed for daytime operations and to radiate excess heat and keep the
astronaut cool. While they could function briefly in the lunar night, long-term
exposure would result in hypothermia.
Many of the Moonlab experiments would see whether or not
man could survive on the moon for extended periods of time. It was hoped at the
time that Moonlab would pave the way for a permanent American presence on the
moon, similar to research stations in Antarctica. One of the biggest experiments
for Project Moonlab involved living off the land. High-powered ovens were used
to bake out elements from regolith, most notably oxygen. The ovens produced a
small quantity of oxygen. Not enough to keep the astronauts alive on its own,
but more than enough to prove the process worked.
Regolith would also be used in more conventional and
familiar means. Along with a small hydroponics garden, the astronauts
experimented with growing various crops directly in the regolith. Early
experiments on Moonlab produced simple cement when water was added to the
regolith. The lunar dirt lacked many nutrients plants required to live, forcing
the addition of fertilizer to the mix. The only available manure on the moon
came from the astronauts themselves, creating a long list of jokes among the
Moonlab crews about “night soil”.
Water used for these small gardens, really little more
than a few potted plants, came from another Moonlab experiment. Waste water
produced by the astronauts went through an intense filtration and purification
regiment, coming out of the machines as clean as it went into the astronauts.
The crews were rather reluctant to drink water reclaimed from their own urine,
and instead used this recycled water in the garden. The Moonlab water
reclamation system was never 100%, and no matter how often water was recycled,
there was always a loss and a need for more water to be introduced to the
life-support systems.
Producing water
from lunar oxygen and hydrogen was one possible solution, but the relative lack
of hydrogen near Procellarum Base made it an expensive proposal in terms of
energy. Schmidt, as well as other Moonlab mission specialists, proposed sending
a probe into polar orbit of the moon to investigate the craters at the poles.
Some craters at the North and South Poles were deep enough that their floors
never saw the light of day. Billions of years of bombardment by comets and other
icy debris may have left residue in these places “were the sun don’t shine”. Any
raw ice that may exist in these locations would not only provide drinking water,
but oxygen to breath and oxygen-hydrogen for fuel.
One of the many goals of Moonlab was to determine whether
or not a permanent base could be established using local resources. If NASA, or
any earthbound organization attempted to establish such a base without using
materials from Earth would require a budget that runs in the hundreds of
billions of dollars. Aside from concrete, the moon has an abundance of elements
that could be used to produce solar cells as well as enough batteries to hold
the charge for the lunar night. The batteries were largely a political decision.
A fission reactor could provide ample power for the nights, but environmentalist
concerns of launching that much fission fuel into space would spark protests far
greater than Moonlab’s RTG, which was designed to last the seven year mission. A
nuclear reactor for a full research base would likely run on the same fuel for
more than twenty years, before requiring refueling.
With all the thought and effort that went into the
experiments, one major detail of life on the moon was overlooked; the dust. With
even a slight static charge, lunar dust would stick to any surface. Vacuum hoses
in Moonlab’s airlock were thought to be enough to remove the fine powder that
claim to everything. The dust would form concrete when coming into contact with
moisture, proving a very serious health problem for anybody who inhaled a small
amount. NASA doctors decorated each of the crewmen with a number of medical
sensors, but had no way to examine the lungs directly. Each Moonlab astronaut
had some exposure to the dust but none at a level high enough to cause permanent
damage.
One incident early in the
mission, happening on January 2, 1975, involved an involuntary reaction to sweat
on the brow. Charles Duke’s dust covered hand smeared moon dust across his
visor, seriously compromising visibility. Fortunately for Duke, it occurred
during a routine outing to inspect the surface experiments littering the surface
around Moonlab. As per Moonlab SOP, Duke was not alone on the surface, and
Schmidt guided him back to the airlock where his helmet underwent a thorough
cleaning and he retrieved his sweatband from inside. After that, he never forgot
to wear the band around his forehead. NASA doctors would continue to badger all
Moonlab astronauts for the remainder of the program, reminding them that sweat
operated the same on the moon as it does on Earth, and thus nothing like in a
microgravity setting.
The lunar
nights proved to be long and trying. It was not that the astronauts had nothing
to do, far from it. Many experiments were ran inside Moonlab. The real challenge
came from having three egos locked in a volume the same as a small apartment
some four hundred thousand kilometers from home. For the most part, the military
discipline of most astronauts’ pre-NASA days held strong. Moonlab even had some
advantages over capsules in that it was large enough that crewmen could grab
small doses of privacy during the fourteen day confinements. EVAs occurred only
when absolutely necessary as the suits were designed for the Apollo landings,
which all happened in broad daylight. Lessons learned from Moonlab III were
implemented in later missions in the form of redesigned environmental
suits.
The term space suit was thrown
out during the Moonlab Program since, as many individuals in NASA, the Press and
so on pointed out that they are not in space, but on the moon. The new “E-suit”
as it was dubbed was not that different from the other soft-bodied suits. The
largest difference was in life-support; the new suits heated as well as cooled.
Hard-shell suit development began even before Moonlab III touched down. The
hard-shells would not require extended periods of prebreathing low pressure air
mixes before EVA. Even with the lower pressure interior of spacecraft (running
with less overall pressure but a higher O2 content), some adjustment was
required. The hard-shells would allow occupants of a future outpost to live in a
standard pressure interior and go EVA without the need of pre-breathing, since
the hard-shell suits would hold the same pressure as the
habitat.
On their down time, crews
were able to call home. Calls were limited and scheduled at certain times as not
to interfere with transmission of data or other communication needs vital to the
mission. One of the more frustrating aspects of working on the moon was the time
lag in communication. At one-point-three light-seconds distance, the round trip
of a message ran at two-point-six seconds. It was small, but the hesitation was
very noticeable. Crews of any potential future Mars mission might look back on
the inconvenience and scoff at anyone complaining about a lag of less than three
seconds. Two-way communication from any object beyond the moon would be all but
impractical. Lovell commented on “having a conversation with a two-and-a-half
second delay” when he was interviewed on CBS News from the
moon.
Three decks of playing cards
were smuggled on to the Moonlab HM before its launch. One engineer suggested
smuggling a copy of Monopoly instead, but the idea was vetoed over concerns of
how a heated match might affect the crew. Anything that could possibly cause a
rise in tension was discouraged. Books were an addition to the crew quarter
section of the HM, including a complete copy of Edward Gibson’s Decline and
Fall of the Roman Empire. Somebody at Mission Control remarked that by the
time anybody was finished reading the collection, it would be time to return
home. In January, the Super Bowl was transmitted to Moonlab, where the crew took
the day off to watch. Media outlets across the country were interested to know
the crew’s favorites.
Moonlab went on
alert on March 2, 1975, when a second Soviet moon mission entered lunar orbit.
Moscow gave all notice to Washington on where it planned to land, as to not
cause any interplanetary incident with the United States. Soyuz 15’s target was
the Copernicus Crater, well away from Moonlab. The Soviets would make their
closest landing to Moonlab in 1976, with an estimated distance between one
hundred and one hundred fifty kilometers away, somewhere on the Ocean of Storms.
While they had no contact with the cosmonaut on the moon, the Soyuz pilot
entered into good natured banter with the crew when his capsule flew overhead.
The Soviets would not bomb them, and if they did, the cosmonaut assured them
that Moscow would let them know in advance.
A real bombardment occurred on April 9, though
fortunately for Earth it was a natural assault upon the moon. A small meteor
slammed into the ground fifteen kilometers away from Moonlab, excavating a seven
meter wide crater. One of the many experiments ran during the Program was a
moon-based radar designed to track threats such as this. What exactly the
astronauts were to do if a meteor was on a collision course with them was not
clear. Hours after the impact, Schmidt and Lovell were on site, collecting
samples and taking pictures of the moon’s newest crater.
The moon buggy took the astronauts further away than the
Apollo rovers. The furthest excursion of Moonlab II was to one of the Apollo
landing sites. Apollo XII landed close to Surveyor 3, and Lovell and Duke
inspected both objects during the February 21-22 drive. Pieces of XII’s LM were
removed and sealed in sample cases for study on Earth, but unlike pieces of
Surveyor 3 there were no bacteria discovered hiding in the shadows. The origin
of the bacteria brought back by Apollo XII is still debated, with a growing
number of scientists believing the samples were contaminated after Apollo XII
left the moon, and not proof of life surviving in vacuum for years on end.
Experiments delivered to the moon on supply missions attempted to duplicate
conditions on Surveyor 3’s camera. None of the bacteria samples in the
experiment survived exposure to the lunar environment for a three month
period.
Moonlab III ended on May 10,
1975, without as much as an injury to any of the crewmen. After spending
approximately six months on the moon, the crew was eager to return home. Even
after returning to Earth, their mission would not be totally complete. One of
the long-term experiments of the Moonlab Program was conducted on the crewmen
themselves. Doctors would give all three astronauts a thorough check-up once
they return to Houston, as well as extensive examination to see how well and how
fast their bodies re-adapt to life on Earth. Any astronaut spending time on the
moon is required to exercise on a daily basis. Often this involves simple EVAs
in a suit with a heavy life-support package. Carrying it on Earth took a great
deal of effort, but in the moon’s lower gravity is almost brought their absolute
weight back to where it was on Earth.
Each astronaut suffered a degree of bone loss in the
lower gravity, but nothing life-threating. Spending six months weightless was a
far greater health hazard than simply weighing less. Six months also happened to
be the estimated transit time for a Mars mission. Thoughts on and designs for
“artificial gravity” argued over whether a Mars mission should have Earth
gravity, Mars gravity or lunar gravity. Rotating living quarters at a lower rate
would reduce to stress on the spacecraft, and Moonlab III proved that six months
at one-sixth Earth’s gravity would still allow the astronauts to function upon
reaching Mars. It was useful data, even if a Mars mission would eventually lay
decades in the futures.
Upon return,
Lovell retired from NASA and the Navy, returning to civilian life. Mission
specialists Schmidt continued studying lunar samples for years after Moonlab
III, though he too retired from NASA and returned to the lab. Charles Duke
continued to serve with NASA for two more years, though he would never return to
space. For almost all of the astronauts, their Moonlab mission would be their
final mission. The test pilot spirit of the astronaut corps always pushed them
for higher, faster and farther, and how could one top a mission to the moon? The
obvious question would be to land on another planet, a feat that none of the
crewmen of the Moonlab Program would live to see.
