On Its Way To A Comet, Spacecraft Checks Out Asteroid
The Rosetta orbiter, which carries the lander
Philae, has completed more than two thirds
of its journey to the comet Churyumov-
Gerasimenko. The most comprehensive
cometary investigation ever, the mission
will deliver the Philae lander to the comet’s
surface for in situ studies. On their way to the
comet, the spacecraft and lander are currently
performing a close flyby of 21 Lutetia, a large
Main-belt asteroid, on July 10. The Philae
lander is operated by the German Aerospace
Center (DLR) in Cologne, Germany.
Since launch, Rosetta has travelled roughly
3 billion miles. The solar-powered orbiter
was launched on an Ariane 5 rocket in 2004.
It has used several gravity-assist maneuvers—
three from Earth and one from Mars—to
gain the necessary momentum, refine its
trajectory, and match the orbit of the comet
once it reaches the outer Solar System. There,
the orbiter will circle the comet and, after
delivering the lander Philae to the surface,
eventually escort the comet on its way to the
Sun.
At about 60 miles in diameter, 21 Lutetia
is one of the larger main belt asteroids. The
lander will investigate whether this asteroid
has a magnetic field and an atmosphere, and
study their characteristics.
Three instruments on the lander will be
switched on during the flyby:
(1) The Rosetta Lander Magnetometer and
Plasma Monitor, ROMAP, a magnetometer
and plasma monitor that will study the local
magnetic field and monitor the interactions
between the asteroid and the solar wind.
(2) MODULUS PTOLEMY, one of two
evolved gas analyzers, which obtains accurate
measurements of isotopic ratios of light
elements by heating solid samples to release
volatiles.
(3) The Cometary Sampling and
Composition experiment, COSAC, which is
also an evolved gas analyzer. It detects and
identifies complex organic molecules from
their elemental and molecular composition.
The ROMAP instrument will be measuring
continuously while it is turned on, and will
be looking for interactions between the
asteroid’s magnetic field and the solar wind.
COSAC and PTOLEMY will perform a series
of “sniff” measurements (five by PTOLEMY
and two by COSAC), which will be used to
help determine whether or not the asteroid
has any kind of atmosphere.
At closest approach (about 2,000 miles
from the asteroid), Rosetta will be travelling
past Lutetia at about 10 miles per second—
or 34,000 miles per hour. This is comparable
to sending a radio-controlled car down a
freeway at roughly 60 miles per hour to take
pictures of a stationary object it passes in the
next lane (about 20 feet away), with the exact
timing of the commands fixed a month in
advance. If that doesn’t sound hard enough,
the planning would also have to be done from
so far away that the freeway would be located
twice as far from the planner as the Moon is
from Earth.

The Internet’s Completely Over
Ask jai…………..
…so says Prince.
During an interview with the Daily Mirrors’ Peter Willis,
the music legend now and formerly known as Prince
declared that the Internet was about as dead as MTV. Wow.
That’s a lot to take in all at once. Had anybody else uttered
such a seemingly kooky-sounding statement my knee-jerk
reaction would have been to dismiss them outright as a
nutjob without so much as a second look back. In this
instance, probably because I’m a huge Prince fan, that
dismissal isn’t coming quite so easy. Looking at the subject
of the statement, even I would have to disagree with him
on the point of the Internet being ‘over’. From a technical
standpoint the Internet has never been more ‘not-over’
than it is right now. In the typical American home, Internet
access has attained the status of a utility such as electricity
or water. Literally. In the typical American business place,
Internet access has not only become an integral part of
many business plans, but the presence of the Internet is
often the main reason for the company’s existence in the
first place. Being a businessman himself, these facts of
modern life are probably not lost on him. His own forays
into using the Internet to distribute his music demonstrate
that he does realize that the Internet does have an integral
place in the world content distribution. In today’s fully
digitized world there simply is no viable substitute for the
‘everywhere-all-the-time’ presence of the Internet when it
comes to content distribution.
So maybe Prince meant that the Internet was over as a
means of content distribution for music artist themselves,
in the sense of having creative and financial control over
their own music. Prince’s well-publicized run-ins with
Warner Bros. over control of his music has made him a bit
of a zealot when it comes to the subject of artist’s control
over their creative endeavors. Creation is one thing, but
distribution is quite another. Usually the record company
is in control of distribution and the profits derived from
digital delivery of music to end users. And the record
company collects the profits. The record company
pretty much makes the deals and calls the shots. And
this is probably what Prince has the most problem with
concerning the Internet. Regardless of which side of the
argument is correct, the reason this statement made the
news in the first place is the notoriety of the source. After
all, the man has sold more than 100 million albums during
the course of his 30-plus year career. This translates into
going triple-platinum every year of his recording history.
Many of his albums were released only on the Internet,
sometimes in bizarre configurations that included tickets
to live shows. If nothing else, he has extensive experience
in getting his music recorded, getting it distributed and
getting it sold. A lot of experience. The distribution model
for his latest musical creation calls for CD’s to be bundled
with copies of the Daily Mirror and given away for free.
I’m not quite sure how this mode of getting one’s music
out to the masses will be better than distribution over the
Internet, but then again, I’m not Prince.
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.
Q: I spend between 10 and 20 hours a week
applying on-line and sending out resumes to
about 20 employers with no results! What
am I doing wrong? Unemployed and
desperate
A: Dear Unemployed and desperate, There
could be numerous and various reasons. So,
I am going to answer your question based on
the information that you have given me. “It’s
a job looking for a job”! You have probably
heard this or read it somewhere. It is true.
You probably worked 35-40 hours a week
for your previous employer and the reward
on payday was money. Now, it is time to
work for you. You should increase the time
you spend job searching to at least 40 hours
a week. This will result in you finding and
applying for more job opportunities and
increase your chances of being contacted by
employers. Your payday will be getting an
interview and hopefully a job.
Q: Everyone thinks I have a great job and
work for a wonderful company. I hate my
company. I hate my job. I hate what I do.
What do I do? Miserable
A: Dear Miserable, It’s time you find out
what you would like to do. Employment
should be enjoyment. Start by identifying
what you really enjoy. This could be
an activity, volunteer work, a hobby or
something that you enjoy doing with your
free time. Look for a company or industry
that is this area. Re-write your resume
and focus on your skills, experience and
education that will target your new interest
and objective. Devote time and a lot of
energy in your new job search. You will be
surprise how many companies you will find
and the type of positions that will be open
to you. 40 hours a week, 52 weeks a year for
the next 30-40 years doing something you
hate does not make a happy person or sense.
Finding out what you like to do will result in
finding the right company, the right job and
being happily employed.
Q: I am being told that I dress inappropriate
for job interviews. I have my own personal
and unique style of dressing and refuse to
change it. Stylish.
A: Dear Stylish,
I would suggest that you research the
company culture before applying for
employment or accepting interviews. This
can be achieved by searching the company
on the internet, reading trade magazines,
talking with employees, sitting outside the
company and observing employees entering
and exiting the building or asking the person
who contacted you for the interview. You
can not change a company’s culture. Find
employment with a company that matches
with your style of dressing. They do exist.
