It’s COLD and WET at The Moon’s South Pole
Frozen water just inches below the Moon’s surface has been
confirmed by an international team of scientists.
Based on data the group obtained with an instrument aboard
the Lunar Reconnaissance Orbiter, or LRO, NASA chose the
impact site for the LCROSS probe, which slammed into the
Moon’s surface last year in October in an attempt to kick up dust
that could be analyzed for the presence of water ice.
“We found significant amounts of water around the north
and south poles, in places where previously we were only
tentatively thinking of it,” said University of Arizona
professor William Boynton.
In addition to confirming water and its distribution in
unprecedented detail, the data included an unexpected
finding.
“To our surprise, some of the permanently shadowed
regions had no water, but some of the areas that receive
sunlight occasionally did have water,” Boynton said.
In other words, water was found not only where it is
supposed to be, but also where it is not supposed to be.
Previously, scientists were convinced water ice could only
persist in so-called Permanently Shadowed Regions, or
PSRs — places on the Moon’s surface where the Sun never
reaches. Unlike Earth, whose tilted axis ensures that any
spot on the surface receives sunlight at some point during
our year-long journey around the Sun, the Moon’s axis is
hardly tilted at all. As a result, some places on the lunar
surface are never exposed to sunlight.
“In some of the craters that are close to the north or
south pole and have very steep walls, no direct sunlight ever
reaches the bottom of the crater,” Boynton said.
“At down to minus 370 degrees Fahrenheit, those PSRs
are colder than Pluto,” added Karl Harshman, a software
engineer with UA’s Lunar and Planetary Lab.
But according to the measurements the group obtained using
the Lunar Exploration Neutron Detector, or LEND, aboard the
LRO spacecraft orbiting the Moon, there is water even in areas
that are exposed to the Sun’s warming rays every once in a while.
To trace the abundance of water on the Moon, the scientists
took advantage of cosmic particles constantly bombarding every
object in space. Since the Moon lacks a protective atmosphere,
the particles strike the surface at close to the speed of light.
When they collide with the atomic nuclei in the dusty soil, they
knock particles off these atoms, mostly protons and neutrons,
some of which escape into space. If one of these particles hits a
hydrogen atom, which is most likely part of a water molecule, it
slows down dramatically, leaving fewer particles fast enough to
escape to space.
By measuring differences in the flow of neutrons coming
from different places on the Moon’s surface, the researchers were
able to infer the amount of water present in the soil: Areas
emitting low neutron radiation indicated that water was
capturing and retaining most of the neutrons, while areas
reflecting high neutron radiation identified themselves as
dry.
In the PSRs near the LCROSS impact site at the Moon’s
south pole, the soil was found to contain up to four percent
water.
“The water might be like some form of ice mixed with the
soil, possibly similar to the slightly damp, frozen soil found
in Alaska,” Boynton said. “We think that in the PSRs, water
ice might be present on the surface, but the fact we found
it in the partially sunlit areas, too, means the upper three
inches or so must be dry dirt; otherwise the sunlight would
cause the water to evaporate.”
Possible origins of the water on the Moon include impacts
of icy comets or hydrogen deposited from solar wind, the
authors noted.
The study was led by Igor Mitrofanov at the Institute
for Space Research of the Russian Academy of Science in
Moscow, the agency that supplied the LEND instrument
used in this study. LRO is managed by NASA’s Goddard
Space Flight Center in Greenbelt, Md.

Walking Miss Daisy
It is 7:30 AM when my neighbor’s cell phone
comes to life, breaking the serene silence of
dawn and rudely awaking all who sleep. The
custom, voice-recorded ring tone resounds
loudly with a chime of “Chris, dog walker….
Chris, dog walker…Chris, dog walker”!
Immediately, Daisy snaps to attention, plants
herself at the foot of the bed, and places one
paw on top of the bed sheet with her fluffy
white ears and tail fully engaged. Next she
begins her usual routine of pacing back and
forth from the bedroom to the leash that
hangs on the hook by the front door, whining
softly as she paces, as if to say, “Please hurry,
get me ready, Chris will be here any minute”.
Soon she is greeted on the front porch by her
beloved walker who gives her a hug and a
pleasant verbal greeting, and off we go. Daisy
is absolutely elated to be leashed and heading
out on yet another exploratory pilgrimage
through the local neighborhood and hillsides!
Within moments, we are well on our way
up the steep hill that takes us to the upper
canyon and ultimate apex of our vigorous
hour-long hike. The sun has just made its way
over the eastern horizon, and has begun its
typical daily task of steaming the pavement
and warming the windows of the houses as
we pass by.
Suddenly, Daisy stops in her tracks; her body
stiffens and she stares ahead, fully focused on
the hillside adjacent to us. Her ears are perked
to a point, her tail is bent forward and the hair
on her back begins to rise up like a porcupine.
I follow her gaze, hoping to see what may
have caught her eye and caused such a sudden
change in her countenance, but I see nothing
out of the ordinary among the massive,
meandering oak trees and low-growing fauna
covering the open area between the houses on
the hill. Seconds later, Daisy relaxes enough
for us to resume our steep upward climb and
I begin wondering to myself what could have
caused her momentary change in behavior. It
crosses my mind that she might have nervous
tendencies due to a traumatic experience that
occurred when she was a puppy, before she
was rescued and adopted. As I ponder the
possibilities, we make our way further up and
around the curve toward the fire road, where
the pavement ends abruptly at the trail head.
It is then that I look up to see a small pack
of coyotes standing in the middle of the trail
just a few yards ahead, looking directly at us!
I am a bit surprised to see so many of them
standing so close, but having seen coyotes
in the neighborhoods and canyons multiple
times before, I know enough to slowly
back away and leave them alone, to avoid
confrontation.
As we head back down the hill, it occurs to
me that Daisy’s sudden change in demeanor
on our way up the hill, had nothing to do with
neurosis, nor was it prompted by something
she saw far away in the distant woods. Daisy’s
brief behavioral interlude had clearly been a
natural response to her inherently keen sense
of olfaction. I had recently read an article that
mentioned a dog’s sense of smell is said to be
1,000 times stronger than that of a human
being, mainly attributable to a vomeronasal
organ that is housed in the dog’s olfactory
chamber. This specialized anatomical
feature, unique to the canine, was no doubt
what allowed Daisy to sense the presence of
the coyotes from so far away, and exhibit a
physical response long before they came into
her field of vision.
We finished our hike, and I delivered
Daisy back to the safety of her home with
lots of hugs and praise. Later that day, I was
reflecting on our walk and I realized that my
initial assumptions about what could have
caused Daisy’s unexpected behavior had been
a prime example of how the domestic dog is
often misunderstood by the human being.
Daisy’s response to the scent of the coyotes
that morning, reinforced my appreciation for
the dog’s sense of smell, but more importantly
it taught me that, if acknowledged from the
proper perspective, a dog’s sensual abilities
and responsive behavior can act as a very
important tell-tale for the human’s safety in
the wilderness. Finally, it was a reminder to
avoid trying to anthropomorphize the dog.
To expect a dog to think and behave the way
a human thinks and behaves is to foolishly
discount the remarkable unique qualities of
the dog that can be of great value and benefit
to the human. In retrospect, my experience
that morning taught me 2 very valuable
lessons; to respect the dog and its inherent
sensual abilities, and to allow myself a healthy
helping of humility as a human being. Who
knew a simple morning walk with a dog could
offer lessons of such value and importance?

Blood & Tea Bags
Can you take pain? When
you slip while cutting melon
do you laugh off the fact that
your left forefinger is now three
millimeters shorter than your
right? Or do you scream if grease
flies from the frying pan and
singes your arm? I can’t bear
nausea or having my blood drawn (the suction
sound grosses me out), but other than that, I tolerate
pain pretty well. I should warn you; this article is
not for the faint of stomach. If you get woozy at the
mention of blood, continue on to another section of
the paper!
January is a time for renewal
of health insurance, and it
was about this time last year
when my dentist’s receptionist
called to cheerily inform me
that my health care provider
had approved yet another
periodontal (gum) surgery. Oh
joy! I’d been through a number
of these operations before my
dentist referred me to my current
specialist. He’s a tall, dark and
suave Spanish guy with an exotic
accent. We’ll call him Dr. Suave.
Inspecting my previous
surgical site, he remarked on how
nicely his last operation turned
out. With my mouth pried open
I managed a weak “Uh huh.” He
said next he’d tackle the upper
front left quadrant of my mouth. For this, he’d need
to harvest tissue from the deep part of my palate,
which might be more painful. If you’re blissfully
ignorant of what these surgeries entail, let me
enlighten you. The surgeon “harvests” some nice
living tissue from the roof of your mouth, then cuts
open your gums and stitches it in like a patch.
Yeah, yeah, I thought, listening to his prediction
of pain. I’d never had to follow any precautions
before. He told to me pick up some vitamin C and
zinc supplements, along with frozen peas to lessen
the swelling. “Uh huh,” I replied, with no intention
of heeding his advice.
The surgery came and went; my eyes closed to
the torture devices being sawed and drilled in me.
I only wish they provided earplugs. Afterward, Dr.
Suave fitted me with a rubber retainer to protect the
harvested area. Underneath was a wad of gauze to
soak up the blood. I numbly drove home, planning
to take it off the next morning.
To my surprise, some blood oozed out the back
of the retainer. The gauze was starting to unravel,
and long strings tickled the back of my throat.
Also, the pain was greater than before. I popped
a couple Motrins and tried to determine if my face
was as swollen as it felt. I attempted eating steamed
veggies, but nearly gagged when I realized the gauze
had come loose and slid down my throat with a
swallow of cauliflower.
By dinner I was tired of wearing the retainer. As
I gingerly removed it my husband asked if I wanted
something soft to eat, but I
cavalierly responded that I was
fine! The first bite of chicken
was okay, but the next had a
distinctly iron flavor, and felt
as if it was warmly expanding
as I chewed. Oh #*! I spit out
the bloody food in a napkin
and grabbed a fresh one to
staunch the bleeding. By then
my husband was trying to be as
helpful as one can be when one’s
spouse’s palate is hemorrhaging.
After a minute of applied
pressure I carefully peeled away
the napkin, but was met with a
fresh torrent of blood issuing
from my mouth like a miniature
geyser. I ran to the kitchen
and held my head over the
wastebasket. Tears came, not because of any pain,
but because the steady spattering wouldn’t stop.
My husband called Dr. Suave, who recommended
compressing tea bags. Since neither of us are big tea
drinkers, my husband called my parents, and they
arrived shortly with a variety of teas. “Oh, yeah…”
my mom nodded as I stuffed bags in my mouth like
a chipmunk, “I had to use tea bags when I had my
wisdom teeth out. I bled like a stuck pig for days.”
When the flow finally ended, I downed vitamin C
and zinc tablets like they were candy, and consumed
nothing but yogurt and lukewarm tea for a week.
Recently a coworker asked me how my gum grafts
went, since she is scheduled to have a similar
procedure. Did it take a long time? Was it painful?
I smiled a thin-gummed grin, “Nah, piece of cake!”
