2004 News Releases
Four months before its scheduled arrival at Saturn, the Cassini-
Huygens spacecraft sent its best color postcard back to Earth of
the ringed world. The spacecraft is expected to send weekly
postcards, as it gets closer to the ringed giant.
The view from Cassini shows Saturn growing larger and more
defined as the spacecraft nears a July 1, 2004, arrival date. On
February 9, Cassini's narrow angle camera, one of two cameras
onboard the spacecraft, took a series of exposures through
different filters, which were combined to form the color image
released today.
"We very much want everyone to enjoy Cassini's tour of this
magnificent planetary system," said Dr. Carolyn Porco, leader of
the Cassini imaging science team at the Space Science Institute
in Boulder, Colo. "And I can say right now the views out the
window will be stunning."
Cassini was 69.4 million kilometers (43.2 million miles) from
Saturn when the images were taken. The smallest features visible
in the image are approximately 540 kilometers (336 miles) across.
Finer details in the rings and atmosphere than previously seen
are beginning to emerge and will grow in sharpness and clarity
over the coming months. The thickness of the middle B ring of
Saturn, and the comparative translucence of the outer A ring,
when seen against the planet, as well as subtle color differences
in the finely-banded Saturn atmosphere, are more apparent.
"I feel like a kid on a road trip at the beginning of our tour,"
said Dr. Dennis Matson, project scientist for the Cassini-Huygens
mission to Saturn and its largest moon Titan. "We've been driving
this car for nearly 3.5 billion kilometers (2.2 billion miles)
and it's time to get off and explore this ringed world and its many moons. I can hardly wait,
but in the meantime, these weekly color images offer a glimpse of
our final destination."
In the coming months, imaging highlights will include near daily,
multi-wavelength imaging of Saturn and its rings; imaging of
Titan beginning in April; Titan movie sequences starting in late
May, when the resolution exceeds that obtainable from Earth; and
a flyby of Saturn's distant moon, Phoebe, in June, at a
spacecraft altitude of 2,000 kilometers (1,243 miles).
Through Cassini, about 260 scientists from 17 countries hope to
gain a better understanding of Saturn, its famous rings, its
magnetosphere, Titan, and its other icy moons. "Cassini is
probably the most ambitious exploration mission ever launched and
is the fruit of an active international collaboration," said Dr.
Andre Brahic, imaging team member and professor at Université
Paris 7-Denis Diderot, France. "It should be the prelude of our
future, the exploration of our surroundings by humanity."
Cassini will begin a four-year prime mission in orbit around
Saturn when it arrives July 1. It will release its piggybacked
Huygens probe about six months later for descent through Titan's
thick atmosphere. The probe could impact in what may be a liquid
methane ocean.
JPL, a division of the California Institute of Technology in
Pasadena, manages the mission for NASA's Office of Space Science,
Washington. The Space Science Institute is a non-profit
organization of scientists and educators engaged in research in
astrophysics, planetary science, Earth sciences, and in
integrating research with education and public outreach. Cassini-
Huygens is a cooperative mission of NASA, the European Space
Agency and the Italian Space Agency.
