Cassini-Huygens spacecraft zooms away from Saturn, scientists are mystified by
some of the images Cassini has sent back from Titan's surface.
They had expected to see oceans or lakes reflecting
like mirrors from Titan's surface. Instead, Cassini sent back murky pictures
obscured by moon clouds, CRIENGLISH.com reported Tuesday.
The ship snapped pictures and took instrument
readings as it passed within 211,000 miles of Titan, about as close as Earth is
to its own moon.
However, scientists have found that a methane cloud
near Titan's south pole is made of unusually large particles, suggesting
something is brewing below.
And they were able to look for the first time at the
surface, using an infrared mapping spectrometer that cut through the haze, to

Titan is a focus of the $3.27 billion mission, which
will spend at least four years exploring Saturn's rings, moons, atmosphere and
