“DEEP IMPACT” COMET HUNTER MISSION COMES TO AN END
After almost 9 years in space that included an
unprecedented July 4th impact and subsequent flyby
of a comet, an additional comet flyby, and the return of
approximately 500,000 images of celestial objects, NASA’s
Deep Impact mission has ended.
The project team at JPL has reluctantly pronounced the
mission at an end after being unable to communicate with
the spacecraft for over a month. The last communication
with the probe was Aug. 8. Deep Impact was history’s
most traveled comet research mission, going about 4.7
billion miles.
“Deep Impact has been a fantastic, long-lasting
spacecraft that has produced far more data than we had
planned,” said Mike A’Hearn, the Deep Impact principal
investigator at the University of Maryland in College Park.
“It has revolutionized our understanding of comets and
their activity.”
Deep Impact successfully completed its original
bold mission of six months in 2005 to investigate both
the surface and interior composition of a comet, and a
subsequent extended mission of another comet flyby and
observations of planets around other stars that lasted from
July 2007 to December 2010. Since then, the spacecraft
has been continually used as a space-borne planetary
observatory to capture images and other scientific data
on several targets of opportunity with its telescopes and
instrumentation.
Launched in January 2005, the spacecraft first traveled
about 268 million miles to the vicinity of comet Tempel
1. On July 3, 2005, the spacecraft deployed an impactor
into the path of comet to essentially be run over by its
nucleus on July 4. This caused material from below the
comet’s surface to be blasted out into space where it could
be examined by the telescopes and instrumentation of the
flyby spacecraft. Sixteen days after that comet encounter,
the Deep Impact team placed the spacecraft on a trajectory
to fly back past Earth in late December 2007 to put it
on course to encounter another comet, Hartley 2, in
November 2010.
“Six months after launch, this spacecraft had already
completed its planned mission to study comet Tempel 1,”
said Tim Larson, project manager of Deep Impact at JPL.
“But the science team kept finding interesting things to do, and through the ingenuity of our mission team and navigators and support of NASA’s Discovery Program, this spacecraft kept it up for more than
eight years, producing amazing results all along the way.”
The spacecraft’s extended mission culminated in the successful flyby of comet Hartley 2 on Nov. 4, 2010. Along the way, it also observed six different stars to confirm the motion of planets orbiting them,
and took images and data of the Earth, the Moon and Mars. These data helped to confirm the existence of water on the Moon, and attempted to confirm the methane signature in the atmosphere of Mars.
One sequence of images is a breathtaking view of the Moon transiting across the face of Earth.
In January 2012, Deep Impact performed imaging and accessed the composition of distant comet C/2009 P1 (Garradd). It collected early images of comet ISON in June of this year.
After losing contact with the spacecraft last month, mission controllers spent several weeks trying to uplink commands to reactivate its onboard systems. Although the exact cause of the loss is not known,
analysis has uncovered a potential problem with computer time tagging that could have led to loss of control for Deep Impact’s orientation.

THIS TOO SHALL PASS
RECESSION PROOF YOUR LIFE WITH MULTIPLE
SOURCES OF INCOME
Even with recent gains in the market, the concept of homeownership is still under attack. Owners feel
let down by falling values, critics say the American Dream has become a nightmare, and others say
renting is the best option now. There is no doubt that many have suffered at the hands of bad lending
practices and economic turmoil associated with the recession.
However… owning a home has always been a huge part of the American Dream, and will continue to
be so long after the current economic crisis and wave of defaults has passed. Our homes are a place
of security for our families and for establishing traditions with our friends.
No one can argue against the benefits that homeownership provides to our communities and to society
in general. Homeowners have a higher level of self-esteem, education, and involvement in civic
activities. Why try to tear down these fundamental truths simply because we are in a downward part
of the always dynamic cycle of real estate?
The time has come to reaffirm the dream of homeownership, but in a more sober and accountable
fashion. We should emphasize responsible ownership for the long term, which helps us and our communities
achieve the common goals of financial and social well-being. Today’s naysayers will change
their tune when the cycle rises again, and you can count on that.
The economic turmoil during the past few years
has spawned a growing number of part-time
business ventures. As the number of company
closures and downsizings escalated during the
recent recession, it resulted in thousands of lay-
off notices for employees. Some were able to find
viable employment and get right back to work.
Some others took the opportunity to take a much-
needed break or enrolled in a school or training
program to retool for a new career. For some, the
shock of being without gainful employment for
an extended period for the first time in their lives
proved devastating, emotionally and financially.
Although there were a series of factors that led
to the most tumultuous downturn since the
Great Depression, the unexpected shake up in
the mortgage industry caught most everyone
by surprise. Almost every industry absorbed
the shock after the Federal National Mortgage
Association (known as Fannie Mae and Freddie
Mac) was deemed ostensibly bankrupt in
September 2008. Without this national safety
net of mortgage insurance, it had a domino effect
on mortgage lenders across the country, having
an adverse impact on every industry section
impacted by the packaging and resale of home
mortgages.
People who had followed the advice of all the
experts on investing in mutual funds and other
instruments tied to the housing market watched
unprecedented declines in the value of their
portfolios and retirement accounts. For many,
this seemed like the end of the world, but for
others, it triggered a reason to rethink, regroup
and retool to make up for lost time and money.
Two of the most important lessons from this
period are to 1) Eliminate all unnecessary debt,
2) Put some money away for unexpected rainy
days ahead and 3) Learn how to establish multiple
streams of income to ensure that your livelihood
is not totally disrupted. This third option allows
for individual creativity and the chance to build
an income stream doing something you love to
do.
An extra stream of income for one individual
may constitute what was previously referred to
as “moonlighting” (i.e. working an extra job to
supplement one’s main income). The income tax
season and the holiday season are two examples
of time periods that additional staffing is needed
to meet the temporary demands of an increased
number of customers. It might be prudent to
consider and prepare for similar opportunities
by enrolling in online training programs or
volunteering to gain work experience to prepare
oneself to make money during the next cycle of
seasonal opportunities. Individuals with talents
for creating new products, novel and practical,
may find a profitable niche by becoming a
vendor at some of the street fairs and community
festivals throughout the region.
This is an opportune time to put some action
behind your creativity with minimal financial
investment, especially considering that a broad
range of products and services can be marketed
and build into a viable revenue stream via the
internet.
