Titan, Saturn's largest moon and the
only moon in the solar system enshrouded in a thick atmosphere, has
fascinated observers since its discovery in 1655. We'll begin with the
discovery of Titan by Christiaan Huygens and quickly cover all the major
scientific discoveries about this intriguing moon right up to the
amazing results that are flowing back now from the Cassini-Huygens
Mission. The Cassini-Huygens Mission to Saturn, a joint NASA-ESA-ASI
mission, was launched in 1997 and reached Saturn in July of 2004. The
Huygens probe, released from the Cassini orbiter on Christmas day of
that same year, drifted down to the surface of Titan on January 14th of
2005, returning spectacular images and data to a world-wide audience.
The Cassini orbiter has gone on to complete almost 80 close flybys of
Titan and has revealed the surface, which is normally hidden by a thick
nitrogen-rich atmosphere filled with aerosols, to be a complex,
exciting, and remarkably earth-like place. There are miles and miles of
dunes, lakes of methane and ethane, and exotic features that might
possibly be ice volcanoes. The atmosphere itself is more dense than
Earth's and is a soup of complex hydrocarbons. Humanity has been
fascinated by the solar system's second largest moon for hundreds of
years; and we're sitting at a ring-side seat as Titan reveals its
mysteries to us.
