WHEN IS AN ASTEROID NOT AN ASTEROID?
On March 29, 1807, German astronomer Heinrich Wilhelm
Olbers spotted Vesta as a moving pinprick of light in the sky.
Two hundred and four years later, as NASA’s Dawn spacecraft
prepares to begin orbiting this intriguing world, scientists now
know how special this object is, even if there has been some
debate on how to classify it.
Vesta is most commonly called an asteroid because it lies
in the orbiting rubble patch known as the main asteroid belt
between Mars and Jupiter. But the vast majority of objects
in the main belt are lightweights, about 60 miles wide, while
Vesta is 330 miles across on average.
“I don’t think Vesta should be called an asteroid,” said
Tom McCord, a Dawn co-investigator based at the Bear Fight
Institute, Winthrop, Wash. “Not only is Vesta so much larger,
but it’s an evolved object, unlike most things we call asteroids.”
The layered structure of Vesta (core, mantle and crust) is
the key trait that makes Vesta more like planets such as Earth,
Venus, and Mars than like the other asteroids, McCord said.
Like the planets, Vesta had sufficient radioactive material
inside when it coalesced, releasing heat that melted rock and
enabled lighter layers to float to the outside. Scientists call this
process differentiation.
McCord and colleagues were the first to discover that Vesta
was likely differentiated when special detectors on their telescopes
in 1972 picked up the signature of basalt, a rock associated with
volcanic activity. That meant that the body had to have melted at
one time.
Officially, Vesta is a “minor planet”—a body that orbits the Sun
but is not a proper planet or comet. But there are more than 540,000
minor planets in our solar system, so the label doesn’t give Vesta
much distinction. Dwarf planets—which include Dawn’s second
destination, Ceres—are another category, but Vesta doesn’t qualify
as one of those. For one thing, Vesta isn’t quite large enough.
Dawn scientists prefer to think of Vesta as a protoplanet
because it is a dense, layered body that orbits the Sun and
began in the same fashion as Mercury, Venus, Earth and
Mars, but somehow never fully developed. In the swinging
early history of the solar system, objects became planets by
merging with other Vesta-sized objects. But Vesta never found
a partner during that big dance, and the critical time passed.
It may have had to do with the nearby presence of Jupiter,
the neighborhood’s gravitational superpower, disturbing the
orbits of objects and hogging the dance partners.
Other space rocks have collided with Vesta and knocked
off bits of it. Those became debris in the asteroid belt known
as Vestoids, and even hundreds of meteorites that have ended
up on Earth. But Vesta never collided with something of
sufficient size to disrupt it, and it remained intact. As a result,
Vesta is a time capsule from that earlier era.
“This gritty little protoplanet has survived bombardment in
the asteroid belt for over 4.5 billion years, making its surface
possibly the oldest planetary surface in the solar system,” said
Christopher Russell, Dawn’s principal investigator, based at
UCLA. “Studying Vesta will enable us to write a much better
history of the solar system’s turbulent youth.”
“Dawn’s ion thrusters are gently carrying us toward Vesta, and
the spacecraft is getting ready for its big year of exploration,” added
Marc Rayman, Dawn’s chief engineer at JPL.

Ask jai……
Ask jai is a weekly column that will strive to honestly answer your job search questions relating
to job searching techniques, networking skills, resume writing and interviewing. The employment
situation is getting better, however, it is still a challenge finding were the jobs are located and how to
get pass the “gate-keepers”. As an Executive Recruiter I was privy to working directly with Corporate
Recruiters and understanding their process in selecting which candidates to interview and hire. I will
candidly answer your questions, possibly bluntly answering you questions, but I will be totally honest.
My objective is to help you achieve your employment goal.
WORLD BACK UP DAY
Q: The Career Center at my college suggested
that I use an Objective Statement at the top of my
resumé. However, several company recruiters
that I have met at job fairs stated that I should not
include an objective on my resumé. What should
I do? Reinaldo
To use or not to use an objective statement? That is
the question. There is a consensus among company
recruiters and HR professionals that objective
statements are old fashioned, and show a lack of
experience and un-professionalism on the part of
the job seeker. I am not really that crazy about using
objective statements on resumés either. However,
there is always a time and place for everything, and
there is for objective statements. I believe objective
statements should be used when you are a job seeker
who is: entry-level, re-entering the job market,
changing careers or industries, recent High School
or College graduate; and who have little or no work
experience, or have worked at a variety of jobs.
An objective statement is always placed on
the resumé right after your name and contact
information. It is placed in this position to grab
the attention of the reader (or resumé screener).
It should be considered a dynamic opener to your
resumé and engage the employer to read and
review your entire resumé. The objective statement
should be short and to the point. No more than
2-3 sentences. The objective statement should
clarify your employment goal and what you have to
offer. Take your time when writing your objective
statement. It is that important. The real trick to this
is making sure you tailor your objective statement
specifically for each position and employer.
Here is an example of a poorly written objective
statement: “To obtain a position that will offer
me a challenge, experience and an opportunity
for growth.” This person’s resume will be tossed,
period! The reviewer will assume the job seeker
does not have experience, they want the employer
to decide where they would fit in the company,
and they bring no added value to the success of the
company. The job seeker should state the position
they are seeking, their experience and how they
would fit in. The following objective statement
will also get your resume overlooked: “Seeking an
entry-level position where I can learn and grow with
a progressive and growing company.” Again, state
the position you are interested in applying. Note:
employers do not want to feel they are paying you
to learn at their company. State your experience.
Next, obviously employers feel their company is
progressive and always growing, or they would not
be recruiting and hiring. Really try to always put
yourself in the shoes of an employer and read your
resumé from their perspective. Then ask yourself,
would you hire you? Finally, only you can decide
when and when it is appropriate to use an Objective
Statement.
March 31st was designated “World Backup Day” (probably by a group of
business interests looking to sell a fair amount of backup solutions, no doubt)
and even though this may not be the most distinguished “World ____ Day”
that you’ve probably ever heard of, now is as good a time as any to turn our
attention toward protecting our digital assets. Even though it’s probably a
VERY good idea to backup your computer system far more frequently than
once year in order to provide adequate protection for your system, if you
haven’t been as attentive to your backup strategy now is the time to get
attentive. As far as backups go, the good one that you do have is worth more
than its weight in gold should the unthinkable happen and your system crash.
Fortunately for the modern computer user there are many options available
to make the task of data protection as simple and as reliable as possible and
this makes backing up important data as simple as possible.
Quite possible the simplest (and quickest) way to backup important data
is to use a USB Flash Drive or Memory Stick. The process for using one a
flash drive as a backup device is usually as simple as plugging the drive into
an available USB port and dragging the data to be backed up over to the
corresponding removable drive and - voila! - the data you’ve selected has
been copied and protected. This is the essence of a backup strategy. The
preceding example is a very limited example of a backup but if you have
data that you must have protected as simply as possible this is the way to
do it. Flash drives can be purchased in sizes as large as 256GB. A drive this
large can backup most peoples’ entire hard drive. The plus side of this type of
backup is ease of use. If you’re interested in a more comprehensive backup
you’ll have to use a backup program such as the backup program that comes
with Windows OS’s ,Time Machine or some other third party program in
conjunction with some removable, writable media. Although this type of
backup is more technically involved it has the plus side of being capable of
recreating a trashed hard drive back to its state at the time of the most recent
backup. For those who’d like the most comprehensive backup without having
to be too involved with the process there are several online backup services
(Carbonite, Norton Online Backup, iDrive,etc). With the online backup
services in order to restore a lost drive you would be responsible for getting
your system back to a state where an internet connection would be possible
and typically these types of backups do not restore programs.
No matter which backup solution you choose be sure to pick one and use it.
You’ll be glad you did.

CANINE KISSESS
One of my
favorite daily
activities
happens in the
late afternoon,
when I am
relaxing in a
lounge chair on my back porch, playing my banjo
and soaking up the peaceful ambience of the
evening. I love listening to the rush of the water
running down the Sierra Madre wash alongside my
yard and the numerous birds chirping away in the
trees. It is then that my beloved bloodhound, “Tater”
typically comes around, plants her enormous front
paw on my foot and gazes up at me with begging
eyes, indicating that she is ready to join me up on
the chair for a snuggle and love session.
That bloodhound of mine is one of the most
affectionate dogs I have ever known, and I believe
I speak accurately on her behalf when I say that
snuggling up to me is one of her favorite pastimes
too. Tater is not a big “licker”, but boy does she love
to snuggle, and she really knows how to hug. That’s
right, she hugs me, big time! When I wrap my arms
around her neck, she leans in toward me, lays her
enormous head on my left shoulder, lets out a deep
breathy moan of contentment, and sits tight in that
position until I finally pull her away.
She definitely prefers hugging over kissing,
although there are times when she does like to give
me a big kiss right in the middle of my face. Usually
when I laugh out loud in response to the funny
faces she makes, she will start licking my face from
chin to brow tentatively and gently, barely touching
my face with the tip of her tongue. Of course I start
laughing even harder when she does that, which
incites her to lick harder and more intensely. The
entire scenario is quite amusing, as I am sure you
can imagine!
While I know where Tater’s mouth might have
been before she starts to lick my face, and at times
her breath can be quite deathly, I allow it because, to
me her licks are actually kisses and they are her way
of demonstrating affection for me.
Having recently read a book entitled “Inside of
a Dog” by Alexandra Horowitz, wherein the author
touches on the very subject of dog kisses, I have
begun to think that my theory about Tater’s licks
being kisses is totally blown. After all, Alexandra
Horowitz is a psychologist who has spent much of
her time focusing on the mind of the canine, and if
that is not enough, she is now a renowned author.
What do I know, right? But still, I cannot help
interpreting Tater’s kisses as a sign of her affection
for me.
I guess it all boils down to the same basic
premise that I tend to adhere to any time I analyze
canine behavior; it is that every dog is indeed an
individual, therefore they each lick or “kiss” for a
variety of reasons. In her book, Horowitz states
that a dog licks only because he smells something
tasty or interesting on your skin, and he hopes to
find something there to eat. In Horowitz’s view, the
dog never licks the one he loves because he wants
to show affection, only for instinctual or practical
reasons.
Well, I tell you what, I was quite disappointed
when I read this chapter, because I kind of like
the idea that my dog loves me enough to kiss me.
Certainly I don’t deny the fact that some dogs will
lick their master or someone else they come in
contact with, simply as a response to something
that wakens their sense of smell or hunger, or even
as a response to some sort of disease, but I refuse
to accept the fact that those are the only reasons
dogs like to lick. I still believe that dogs like to lick
or “kiss” as a means of showing their affection. The
fact that Tater only does it when I laugh at her silly
antics while we are spending intimate time together
tells me that she is not being driven by her appetite
or by her internal instincts, rather it is her way of
connecting with me.
Perhaps I just need to believe my dog is capable of
that sort of understanding and affection, so I work
hard to find it and I assign meaning to it…maybe,
maybe not! Still, I say every dog is an individual
being, so who knows what your dog is thinking
when he licks your face? Ultimately, I think it is
all good when you get a big sloppy kiss from your
canine companion. There is no doubt that it can be
a healing experience, and who would look that “gift
horse” in the mouth? What have you got to lose? ~
Love and let lick!

WHAT HAPPENED TO THE HORN?
Do you notice something
missing every day
around noon? Until my
dad pointed it out to me,
I hadn’t realized that the
Sierra Madre Volunteer
Fire Department has
stopped daily testing
their emergency air horn! Since I don’t
work in Sierra Madre, it’s understandable
that I didn’t immediately notice its absence.
But now I really miss that dependable blast
signaling the middle of the day!
If you are unfamiliar with the legendary
air horn, it stands (now silent) at Baldwin
and Montecito with a big sign under it
warning passers by of three short, loud
daily blasts. The idea is that, in case of
emergency, the horn will alert residents to
tune in to local news outlets for information.
It is a beloved relic from the days before cell
phones and other technological advances in
communication. In its hey day, there was
even an elaborate “code” of blasts to alert
firefighters as to which area of the city was in
jeopardy. In recent years, the horn sounded
daily at noon, and then at 7:00 pm. James
Carlson, Management Analyst for the city,
informed me by email that the silence of the
horn occurred some years ago when it was
“constantly going off late, not at all, or was
making odd sounds.” What odd sounds
was it making? Was the horn wheezing like
a kazoo or blowing raspberries? It almost
sounds like the work of adroit pranksters.
Carlson assured me, however, that the
horn is in the process of being repaired,
which begs the question how it got broken?
He responded that it had suffered a number
of mechanical ailments, and that “we finally
got to the point where it was decided that
the equipment really needed to be replaced.
Understand, there is no ‘store’ for fire horn
equipment, so we are putting together the
same system with some technical assistance
from a number of volunteers in the area.”
God bless them! If that doesn’t just typify
Sierra Madre then I don’t know what does.
Where else would there be a public outcry
over the removal of an antiquated alarm
more because of its importance to the town’s
history than its safety, and volunteerism
to patch the thing up? I heartily look
forward to its reinstatement. If I had any
technological competence I’d offer my own
services.
Carlson also stated that when the horn
returns to its working capacity it will be
tested daily at 5 pm rather than noon or 7
pm. He reported that there were a thousand
different public opinions regarding when
the horn should sound, and after presenting
the decision to the city council, they landed
upon 5 pm. Personally I think noon and 5
pm is the best option. Noon seems fitting
because it marks the middle of the day,
lunch, etc. I also agree with 5 pm because
we should all be reminded of when the
cocktail hour starts.
Speaking of cocktail liberality, if you
can’t wait for our volunteers to fix the air
horn, you can always hear its blaring glory
in that 1950’s classic “Invasion of the Body
Snatchers,” truly a cultural and cinematic
gem every Sierra Madrean should
experience!
Disclaimer! I didn’t anticipate discovering
such a wealth of information about the fire
horn when I started this piece. Therefore,
I acknowledge that there are other
knowledgeable historians, George Maurer
and Debbie Henderson, who I was not
able to interview due to time constraints.
Perhaps I will revisit this topic in a future
article. Until then, watch “Invasion” if
you haven’t already, and fix yourself a dry
martini at five!
