NASA’S EUROPA MISSION BEGINS WITH SELECTION OF SCIENCE INSTRUMENTS
NASA has selected nine science instruments for
a mission to Jupiter’s moon Europa, to investigate
whether the mysterious icy moon could harbor
conditions suitable for life.
NASA’s Galileo mission yielded strong evidence
that Europa, about the size of Earth’s moon, has
an ocean beneath a frozen crust of unknown
thickness. If proven to exist, this global ocean
could have more than twice as much water as
all of Earth’s oceans. With abundant salt water,
a rocky sea floor, and the energy and chemistry
provided by tidal heating, Europa could be the
best place in the solar system to look for present-
day life beyond our home planet.
“Europa has tantalized us with its enigmatic icy
surface and evidence of a vast ocean, following
the amazing data from 11 flybys of the Galileo
spacecraft over a decade ago and recent Hubble
observations suggesting plumes of water shooting
out from the moon,” said John Grunsfeld,
associate administrator for NASA’s Science
Mission Directorate in Washington. “We’re
excited about the potential of this new mission
and these instruments to unravel the mysteries
of Europa in our quest to find evidence of life
beyond Earth.”
NASA’s fiscal year 2016 budget request includes
$30 million to formulate a mission to Europa. The
mission would send a solar-powered spacecraft
into a long, looping orbit around the gas giant
Jupiter to perform repeated close flybys of Europa
over a three-year period. In total, the mission
would perform 45 flybys at altitudes ranging from
16 miles to 1,700 miles.
The payload of selected science instruments
includes cameras and spectrometers to produce
high-resolution images of Europa’s surface and
determine its composition. An ice penetrating
radar will determine the thickness of the moon’s
icy shell and search for subsurface lakes similar
to those beneath Antarctica. The mission also
will carry a magnetometer to measure strength
and direction of the moon’s magnetic field, which
will allow scientists to determine the depth and
salinity of its ocean.
A thermal instrument will scour Europa’s
frozen surface in search of recent eruptions of
warmer water, while additional instruments will
search for evidence of water and tiny particles
in the moon’s thin atmosphere. NASA’s Hubble
Space Telescope observed water vapor above the
south polar region of Europa in 2012, providing
the first strong evidence of water plumes. If the
plumes’ existence is confirmed—and they’re
linked to a subsurface ocean—it will help
scientists investigate the chemical makeup of
Europa’s potentially habitable environment while
minimizing the need to drill through layers of ice.
Last year, NASA invited researchers to submit
proposals for instruments to study Europa.
Thirty-three were reviewed and, of those, nine
were selected for a mission that will launch in the
2020s.
“This is a giant step in our search for oases
that could support life in our own celestial
backyard,” said Curt Niebur, Europa program
scientist at NASA Headquarters in Washington.
“We’re confident that this versatile set of science
instruments will produce exciting discoveries on
a much-anticipated mission.”

At one time, life stretched
out like eternity, like the last
scene from “The Good, The
Bad, The Ugly,” where you knew there were winners
and losers and fools, and you hoped desperately
that you’d be a winner. Well, at least a good guy.
That’s the perspective of a child, seeing the world
through simplistic eyes, black and white, good and
bad, right and wrong. That’s good, really, but as
Mark Twain once noted, there is enough good in
the worst of us, and enough bad in the best of us,
that we should quit pretending and start working
together. At least Twain said something like that,
and what he meant was that only in movies and
childhood dreams do we ever get to see absolute
clarity which doesn’t exist in the real world.
In childhood, I assumed that the older bodies
also contained minds that were more developed,
and advanced, and therefore more objective and
mature. I assumed that parents were the fair
arbiters of disputes and that elected officials took
those positions because they cared about the good
of the people they represented. I believed in the
Jimmy Stewart world of “It’s a Wonderful Life,”
even though I never found it.
I believed that there must be a sanctuary of sanity
somewhere where people practiced lives of sanity
and non-prejudice, and where fraud and cheating
were unheard of. I lived on a farm for awhile right
after high school, and I felt that perhaps there, in
the rough existence where your work resulted in a
very tangible result that supported your existence,
it was hard to cheat and defraud, and the folks had
pride in their skills, their
sense of community, and their honesty.
Could the urbanization of the world be part of the
culprit in our fall from grace? Perhaps.
But it’s still no excuse. Even if I never found
Shangra-la on earth, I have not stopped believing in
the principles by which such a place must exist. For
example, you must keep your word. Yes, printed
papers are OK for poor memories, and for those
who are inclined to twist the words later to mean
something else from the original intent. But when
you twist your word, and bend your word, you bend
your very soul, and you dis-integrate your very
integrity. That’s why my father always said to keep
your word, that a person is only as good as their
word. Even in middle-class Pasadena, my father
knew that there was an ineffable something about
the giving and keeping of your word. In Shangri-la,
you would always keep your word.
In my vision of Paradise, there would be work,
but the god that we all trusted wouldn’t be money.
Money, or some version of it, seems inescapable
for daily commerce and for converting your work
and time into a medium of useful, recognizable
exchange. But in Paradise, money would naturally
be a tool to assist others to get their own enterprises
going, and to provide for the common good. People
would not be obsessed by money and would not be
driven by the desire for money. Killing for money
would be unheard of.
Work must have a tangible result, within the
framework of a goal. A person must naturally
feel uplifted by doing one’s work, and when one
knowingly works at a menial and pointless job to
fulfill someone else’s desires and goals, it’s hard to
feel uplifted.
Of course, bits and pieces of this Shangra-la exist
right now, everywhere, in most people. I believe that
everyone has an innate desire to find rightness, and
even fairness, and everyone ultimately recognizes
the objective reality of the Law of Thought, that
what you think and what you do has ramifications
that are scientific result of those specific thoughts
and actions.
If you inwardly believe in the possibility of a Paradise
on earth, you must start to grasp those principles of
living and thinking that lead to Shangri-La. And
though you must do so personally, on your own,
it is fortunate that there are others, if you can find
them, who are also seeking a higher road.
Shangri-La is not a place that you find, but rather, a
place that you earn the right to be a part of, by the
evolution of your thought and actions. What does
that mean? What must someone do? Again, the
answers are everywhere, hidden in plain view. They
go by such names as learning to think, separating
feeling from emotions, distinguishing empathy
from sympathy, learning to use words precisely,
working hard to see world events objectively, and
not subjectively based on your personal cultural
bias. It means learning the practical value and
living the precepts taught by all the great Way-
showers of history, from all cultures. Ever heard
of the Golden Rule? That’s a good place to start.
How about the 10 Commandments? Another good
starting point.
One winter night during high school, my friend
Nathaniel and I bicycled into a little side canyon
of the Angeles National Forest, and we made
a safe little fire in our campground and talked
about the meaning of life and how we thought
that civilization might fail. It had never occurred
to us that we are barely civilized now, and we only
believe we are “civilized” because of our material
wealth and technological toys. We bemoaned
the fact that society is on the fast road to uncivil
barbarousness, and wondered what could be done,
and what should be done.
We always toyed with the idea of becoming hermits
and hiding out in a cave somewhere, but both of
us were way too social to live out our lives in a
cave. By whatever choices we made, we felt that
everyone should be a good example, and no one
should assume that there is no hope for the future.
Our civility, our culture, our sense of civilization,
after all, is an internal concept that we first keep
alive inside our thinking. Once that flame is bright
within, it is proper to share with others, and attempt
to be a part of the solution to the many problems we
see all around.
