BOB SILVERS
RETURNS WITH A NEW ADVENTURE
AND
PUTTING ON THE MILEAGE
Pam Eastlick for the Marianas Variety
Greetings
and welcome to The Deep column and the deepest radio show on
Earth. The Deep is the science talk radio program that takes
you from the depths of the ocean to the farthest reaches of
the universe. This week on The Deep hosted by Jim Sullivan and
aired at 6:00 this evening on K-57, we’ll talk about one
of our favorite topics, sharks. Then we’ll talk about
The Ranger, a ship with an interesting past and an interesting
future. We’ll have some expedition calls and, of course,
our science news updates. We’ll also be taking your phone
calls. Tune in tonight! Log on to www.thedeepradioshow.com for
all the latest and deepest news!
ROAMING WITH THE HERCULES
If you are a long-time listener of The Deep radio show on K-57,
you certainly remember Bob Silvers and his weekly calls from
the deck of the Arctic Lady. Bob and his crew sailed the ship
from Alaska, down the west coast of North and Central America
and through the Panama Canal. They then sailed north through
the Caribbean, up the eastern coast of Florida and across the
Atlantic Ocean. They made several stops in the Mediterranean
and ended their voyage 14,000 miles later in Beirut, Lebanon
where they delivered the Arctic Lady to her owner. Along the
way, they encountered all kinds of wildlife, on sea and on land
and met many wonderful people. For a full account of this astounding
voyage, visit www.bandacorp.com/ArcticLady.htm. You’ll
be astounded, and be sure to take plenty of time to explore
the site.
After his yearlong odyssey
with the Arctic Lady, Bob Silvers was ready to tackle
another challenge and he found it with the 122-foot research
ship the Hercules. |
 |
The Hercules is owned by the
RPM Nautical Foundation, a non-profit organization that uses
state-of-the-art technology to conduct nautical archeology.
The Hercules is based in Malta and is designed to support a
wide range of functions. These include remotely operated vehicles
(ROV’s). These cameras and robots can sink to depths beyond
the capabilities of divers, sample the ocean bottom and artifacts,
and take pictures. The Hercules can also support manned submersibles
and diving operations.
In addition, the Hercules
is equipped with multibeam and sidescan sonar as well as a built
in GPS and an eight-station data processing center. She also
has a large crane with a five-ton lifting capacity. She carries
a crew of four to six and can accommodate up to ten research
scientists.
 |
The Hercules will first visit the Mediterranean port of
Valletta, the capital city of the island of Malta. The researchers
hope to complete a topographical map of the harbor’s
bottom and discover the location of several torpedo boats
sunk during World War II. |
Tune in to The Deep this evening
for our first report from Bob Silvers on this marvelous ship
and the expeditions planned for her this summer. It will be
great to have Bob back!
CAN YOU SAY ‘ENERGIZER
BUNNY’?
NASA has just approved up to 18 more months of operations for
Spirit and Opportunity, the twin Mars rovers that have already
surprised engineers and scientists by continuing active exploration
for more than 14 months.
Both rovers are nearing targets that seemed well out of reach
a year ago. Opportunity is about half a mile from a region called
"Etched Terrain," where scientists hope to find rocks
exposed by gentle wind erosion rather than by disruptive cratering
impacts. They also hope to find rocks from a different time
in Mars' history than any examined so far.
Opportunity landed in a vast flat plane and the rover drivers
have been setting speed records. Opportunity has overtaken Spirit
in total distance driven and has gone more than 5 kilometers
(3 miles) -- eight times the original goal. On March 20, Opportunity
also set a new Martian distance record of 220 meters (722 feet)
in a single day's drive. Opportunity's solar panels, though
now dustier than Spirit's, still generate enough power to allow
driving for more than three hours on some days.
Spirit is in much rougher
terrain than Opportunity, climbing a rocky slope toward the
top of "Husband Hill." On March 9, Spirit had its
solar panels cleaned by a friendly Martian dust devil and with
its formerly balky right-front wheel now working normally, it
made some longer one-day drives in March than it had for months.
Both rovers do have some signs
of wear and exposure. Spirit's rock abrasion tool has lost some
teeth and the remaining ones are worn after exposing the interiors
of over fifteen rocks, five times more than the design goal
of three rocks. Scientists are also trying to determine if Opportunity's
miniature thermal emission spectrometer is still usable despite
tests indicating a problem last month. All other instruments
on both rovers are still working normally.

FAREWELL CAPTAIN MELODY
 |
Our host on The Deep, Jim Sullivan has lost his only crew
member and best friend. Farewell Captain Melody. May you
sail forever among the stars! |
Whether we’re visiting
the Hercules in Malta or Spirit and Opportunity on Mars, The
Deep is the place to be on K-57 tonight at 6:00 p.m. We’ll
have some expedition calls and take your phone calls. Don’t
miss it!
