Only a few space probes have already visited the second largest planet in the solar system and its moons:
– Pioneer 11
– Voyager 1 & 2
– Cassini/Huygens
All of them have returned spectacular data and images back to earch. The current attempt with the NASA/ESA space probe Cassini/Huygens focusses on the moon Titan. The lander Huygens will descent through the thick athmosphere of Titan and send data back to the Orbiter Cassini to be relayed to earth. The orbiter will stay in orbit around Saturn for years to observe Saturn and its moons.
Current images from Cassini may be found on the CICLOPS website.
