Cassini/Huygens

The CASSINI mission is named after the french astronomer Giovanni Domenico Cassini (1625-1712) who discovered 4 moons of Saturn and the ring system in the 17th century. CASSINI is a joint effort of NASA, ESA and the Italian space agency ASI. It consists of an orbiting spacecraft (CASSINI ORBITER) and a probe (HUYGENS PROBE) which has been delivered to Saturn's moon Titan. The probe is named after the dutch physicist and astronomer Christiaan Huygens (1629-1695).

Cassini was successfully launched onboard a TITAN IV B rocket from Cape Canaveral on October 15, 1997, 08:43 UT. After a journey of seven years it finally reached Saturn in July, 2004 after gravity assists from Venus, Earth and Jupiter.

Since 2004 the spacecraft orbits around Saturn and has already extended the knowledge of Saturn's magnetosphere, the rings, the moons and the planet itself significantly.

Cassini is the second largest spacecraft after Galileo which was ever launched by NASA. More than half of the total mass is fuel to carry out maneuvers in interplanetary space and in Saturn's magnetosphere.

Titan

Titan is Saturn's largest moon and orbits the planet at a distance of about 20 Rs. Remarkable is the dense atmosphere that mostly consists of nitrogen (98 %). The Cassini spacecraft has performed more than 100 flybys and revealed some of the mysteries about this interesting moon. It's long known that Titan is the only moon in the solar system that has an atmosphere and scientists speculated about the possibility of liquids on the surface. The thick haze layers preclude the view in visible light.
