LIFE AND WORK AT
A MOON BASE
People will someday return to the Moon. When they do, it will be to stay.
They will build a base on the Moon, the first settlement in the beginning
of an interplanetary migration that will eventually take them throughout
the Solar System.
There will be lots to do at a lunar base. Geologists will study the
Moon with the intensity and vigor they do on Earth, with emphasis on field
studies. Astronomers will make magnificent observations of the universe.
Solar scientists will study the solar wind directly and investigate past
activity trapped in layers of regolith. Writers and artists will be inspired
by a landscape so different from Earth’s. Life scientists will study how
people adapt to a gravity field one-sixth as strong as Earth's, and figure
out how to grow plants in lunar greenhouses. Engineers will investigate
how to keep a complex facility operating continuously in a hostile environment.
Mining and chemical engineers will determine how to extract resources
from Moon rocks and regolith. The seemingly dry lunar surface contains
plenty of the ingredients to support life at a Moon base (oxygen and hydrogen
for water, nitrogen and carbon for the growth of plants), including the
construction materials to build and maintain the base (regolith can be
molded into bricks; iron, titanium, and aluminum can be smelted and forged
into tools and building materials). It will be an exciting, high-tech,
faraway place inhabited by adventurous souls. [See the Unit 3 activities
beginning on Page 99.]

Where moon rocks hang out
Since arrival on Earth, lunar samples have been treated with the respect
they deserve. Most of the treasure of Apollo is stored at the Lunar Curatorial
Facility at the Johnson Space Center, Houston, Texas. A small percentage
is stored in an auxiliary facility at Brooks Air Force Base near San Antonio,
Texas, placed there in case a disaster, such as a hurricane, befalls Houston
and the samples are destroyed. Many small samples are also in the laboratories
of investigators around the world, where enthusiastic scientists keep
trying to wring out the Moon's secrets.
The Curatorial Facility is one of the cleanest places you'll ever see.
To go inside, you must wear white suits, boots, hats, and gloves, outfits
affectionately known as 'bunny suits.' Wipe a gloved hand on a stainless
steel cabinet and you will not find a trace of dust because the air is
filtered to remove potential contaminating
particles.
The samples are stored in a large vault, and only one at a time is moved
to a glove box. You can pick up the rocks by jamming your hands into a
pair of the black rubber gloves, allowing you to turn a rock over, to
sense its mass and density, to connect with it. A stereomicroscope allows
you to look at it closely. If you decide you need a sample, and of course
you have been approved to obtain one, then expert lunar sample processors
take over. The sample is photographed before and after the new sample
is chipped off. This is time consuming, but valuable to be sure we know
the relationships of all samples to each other. In many cases, we can
determine the orientation a specific part of a rock was in on the surface
of the Moon before collection.
A select small number of pieces of the Moon are on display in public
museums, and only three pieces can actually be touched. These so-called
lunar "touchstones" were all cut from the same Apollo 17 basaltic
rock. One touchstone is housed at the Smithsonian Air and Space Museum
in Washington, D.C. Another touchstone is at the Space Center Houston
facility adjacent to the Johnson Space Center. A third touchstone is on
long-term loan to the Museo de Las Ciencias at the Universidad Nacional
Autonoma de Mexico. Visitors to these exhibits marvel at the unique experience
of touching a piece of the Moon with their bare hands.
Scientists as poets
Scientists do not view the world in purely objective ways. Each has biases
and a unique way of looking at the world. Science is not done solely with
piles of data, hundreds of graphs, or pages of equations. It is done with
the heart and soul, too. Sometimes a scientist is moved to write about
it in elegant prose like that written by Loren Eisley or in poetry, like
the poem written by Professor Carlé Pieters of Brown University.
Dr. Pieters holds her doctorate from MIT and is an expert in remote sensing
of planetary surfaces. She is especially well known for her telescopic
observations of the Moon. The poem first appeared in the frontispiece
of Origin of the Moon, published by the Lunar and Planetary Institute.
