Huygens (USA,ESA)	15-Oct-97	Titan-Centaur	5.634 kg	The Huygens Titan lander separated from Cassini on Dec 25, 2004. Huygens reached Titan's outer atmosphere after 20 days and a 4 million kilometre cruise. The probe started its descent through Titan's hazy cloud layers from an altitude of about 1270 km on 14 Jan 2005 at 09:06 UT. Touchdown on the Titanian surface was at 11:38 UT, at latitude 11 S longitude 192W. First successful attempt to land a probe on another world in the outer Solar System.
Cassini (USA,ESA)	15-Oct-97	Titan-Centaur	5.634 kg	On Dec 28, 2009 at 0017 UTC Cassini made flyby 123TI/T64 of Titan at a height of 955 km; on Jan 12, 2010 at 2310 UTC it made Titan flyby 124TI/T65 at a height of 1073 km. The Cassini probe made a 99 km flyby of Dione on Dec 12, 2011 followed by a 3586 km flyby of Titan on Dec 13.
