How does one prepare mentally for a
space walk, for the disorienting feeling of being out in space 200 or so miles
above the earth and orbiting, or falling, 17,500 miles an hour? All astronauts
go through hours and hours of training.
They already have a degree in some field such as engineering or physics;
some are pilots and have military experience, or even education degrees. They are trained in physical skills, language
skills, experiments and safety. These
men and women are some of the best trained and all around talented people on
the planet, and they are hoping to use those skills off of this planet. To prepare for living in micro gravity they
spend hours in a giant pool learning to perform various activities. Those
chosen to perform EVA’s, or extra vehicular activities or spacewalks train even
longer in the underwater environment.
Simply floating in a pool isn’t exactly the same as the micro gravity
experience, but with weights added the astronaut becomes neutrally buoyant. They neither float up nor down. In this manner they learn to perform the
tasks and they have the opportunity to experience some of the difficulties
before being in the exposed and deadly environment of space.
Even with all the training and
teaching the very real experience of hanging in space, of seeing our home
planet Earth in the sky above while being surrounded by stars and darkness has
to be overwhelming. How can a person
mentally prepare for this? So many
astronauts have felt a deep sense of euphoria or joy, and others have struggled
with fear and awe. There have been
enough strong feelings and the reactions shown by different people on EVA’s
that NASA has come up with a name for the feeling, the Overview Effect. In a book I recently read, the author wrote
that one way to have just a tiny experience of what the feeling might be like
is to climb a telephone pole, wearing a safety harness, stand on top of the
pole as it wiggles, and then jump off.
The person on top of that pole is secure with the harness and yet feels
vulnerable. Now imagine the same
activity but with no ground beneath you, just empty space, and no ground above
you, just a round blue planet over your shoulder.
This overview effect is more than
just the fear of falling. I imagine the
fear of heights, the fear of having no ground or anything solid to really grab,
and the feeling of vulnerability is only one small part of the multitude of
emotions that invade the mind. Just
thinking about how large and incomprehensible the size of the Universe is can
be unsettling, but imagine thinking about that while hanging outside of your
spacecraft home, surrounded by the immensity of space, the deepness of the
darkness and the number of stars going on and on.
One astronaut said that standing on
the platform of the Canada Arm, stuck out in the empty darkness of space and
seeing the earth below him was so overwhelming he had to close his eyes for a
moment and calm down.
Another astronaut
wrote about struggling to perform some task, then looking away for a moment at
the view and almost forgetting what he was supposed to be doing.
It took a strong discipline to get back to
work, even knowing his time was limited due to air and other safety issues.
Others have been so taken with the beauty and
the wonderful feeling they didn’t want to come back inside.
Almost everyone who has gone out into space
or who has had the ability to look out at the earth from space found himself or
herself changed by the experience.
The Russian Cosmonaut Alexei Leonov
performed the first spacewalk in 1965.
He said, “My feeling was that I was a grain of sand.” He felt small and insignificant, but others
feel larger and part of something huge.
Edgar Mitchell of Apollo 14 spoke
of a “Profound sense of connectedness, with a feeling of bliss and timelessness. He spoke about becoming profoundly aware that
each and every atom in the Universe was connected in some way and on seeing the
Earth from space he had an understanding that all the humans, animals and
systems were part of the same thing, a synergistic whole.” He has said that his
experience in space changed his life.
Seeing our small part in such a
large vast universe, and seeing the earth from a distance puts all the troubles
and angers, the borders and the wars, the petty fights and ideologies into
perspective. Another quote from
Mitchell, written after a moonwalk, reflects this. He said, “You develop an instant global
consciousness, a people orientation, an intense dissatisfaction with the state
of the world, and a compulsion to do something about it. From out there on the moon, international
politics look so petty. You want to grab
a politician by the scruff of the neck and drag him a quarter of a million miles
out and say, ‘Look at that, you S. O. B.”
Ed White made a space walk during the
Apollo program, and mission control had a hard time convincing him to return to
the capsule. He said when he finally
returned, “It was the saddest day of my life.”
Gene Cerman, while looking at the
earth from space was inspired to look for a deeper meaning. He wrote, “It was too beautiful to happen by
accident…There has to be a creator of the universe who stands above the
religions that we ourselves create.”
The best quote is from the first
man to walk on the moon. He had similar
sentiments to the first man to perform the space walk. Neil Armstrong wrote, “It suddenly struck me
that that tiny pea, pretty and blue, was the Earth. I put up my thumb and shut one eye, and my
thumb blotted out the plant Earth. I
didn’t feel like a giant. I felt very,
very small.”
No one can prepare for these
feelings and experiences, but we all can learn from them. From space the Earth has no borders. The
Earth is a huge blue marble that holds all we love, all we need and all we must
care for within its atmosphere. Let us
protect and love that giant ball while we continue to push our limits and
explore farther away from home. Moving
away from Earth helps us to respect it, to hate anything that might try to harm
it, and to hopefully grow as a species into the connected beings made of atoms
and stardust that work to care for each other and our home as best as we
can.
