TITAN
Largest moon of Saturn
Titan was discovered in
1655 by Dutch astronomer
Christiaan Huygens.
Titan is the only moon
in the solar system with a
significant atmosphere.
Larger than the planets
Pluto and Mercury, the moon
is the second largest in the
solar system, behind Gany-
mede which orbits the planet
Jupiter.
Scientists believe the
moon is composed half of
water and ice, while the other
half is made of rock.
The atmosphere is 94
percent nitrogen, but the
remainder is made up of
hydrocarbons and methane.
Temperatures on the
planet can reach as low as
292 degrees celsius.

This raw image returned by the ESA Huygens probe during its successful
descent to the surface of Saturn's moon, Titan, apparently shows
short, stubby drainage channels leading to a shoreline.

The above diagram shows the approximate flight path Cassini-Hyugens took in its journey to Titan. After using
the gravitational pull of Saturn to perform three "slingshot" maneuvers around the gas giant over a period of
months, Huygens finally was able to land on the moon.

Federal health advisors warn against cholesterol drug

1ru found to
be gous for
heart patients
BETHESDA, Md. (AP) - Federal health
advisers recommended against over-the-counter

the drug - they were too young, for instance,
or their cholesterol levels weren't high enough.
In other cases, their risk of heart disease was so
high that they should be seeing a doctor and pos-
sibly receiving a stronger drug.
"I think that it is the right thing to do but I
don't think we're there yet," said Frank Davi-
doff, editor emeritus of Annals of Internal Medi-

Several members of the panel said they would
like to see an in-between option, where patients
can buy the drug without a prescription but only
after-speaking with a pharmacist. This option is
available in Britain, which last year began sell-
ing a similar drug, Zocor, under these rules. And
U.S. states sometimes order the drugs only be
sold be from "behind-the-counter."
