The Amazing Cassini orbiter has completed nearly one year
of its four-year orbital tour of Saturn ! All orbiter systems are performing normally.
All consumables usage is running per predict.
All instruments are performing well
Huygens atmospheric probe completed its entry and descent through
Titan's atmosphere and data return to Earth on January 14, 2005.
The probe's mission was remarkably successful, returning 2 hr 27 min of data during atmospheric descent, 1 hr 12 min of data from the Titan surface

Cassini has completed 10 of its planned 75 orbits of Saturn.
6 of 45 targeted Titan encounters (5 of which were closer than 2500km)
Cassini has found radio bursts associated with lightning. These bursts come in storms at a period thought to be the rotation period of the associated storms.These storms apparently come and go, much like storms on Earth.

Cassini has taken a total of 31,167 images so far, 21,874 being of Saturn and its rings,and 6522 visual and infrared mapping spectrometer cubes.
Cassini has traveled 63,000,000 miles that is the equivalent of 194,000 miles to the gallon(not bad eh)
Cassini has received 320,000 uplinks of commands

Cassini was very expensive (about the same price as Hubble plus a few Hubble Servicing missions), but it's worth it.
