JUICE is headed toward Jupiter\u2019s icy moons, while Europa Clipper is zeroing in on one of Jupiter\u2019s moons, Europa, where there\u2019s already scientific evidence for the ingredients of life. But did you know we\u2019ve already landed on a moon of a gas giant? On January 14, 2005, ESA\u2019s Huygens spacecraft descended through the atmosphere of Saturn\u2019s moon Titan, to what astronomers thought might be a wet world, but in reality it looked a bit like \u2026 Mars?<\/p>\n<p>Huygens made the trip to Saturn aboard NASA\u2019s Cassini spacecraft. After Huygens patiently waited its turn aboard Cassini for seven years, Cassini released Huygens on its trip toward Titan on December 25, 2004. On January 14, Huygens entered the moon\u2019s atmosphere and took two hours to reach the surface. And on the surface it continued to record and send information for about 90 minutes.<\/p>\n<p>The 2025 EarthSky Lunar Calendar is now available! A unique and beautiful poster-sized calendar. Get yours today! <\/p>\n<h3>The descent and landing<\/h3>\n<p>Here\u2019s NASA\u2019s description of the event: <\/p>\n<blockquote>\n<p>Huygens entered Titan\u2019s atmosphere at 09:05:56 UTC on January 14, 2005, and within four minutes had deployed its 28-foot (8.5-meter) diameter main parachute.<\/p>\n<p>A minute later, Huygens began transmitting a wealth of information back to Cassini for more than two hours before impacting on the surface of Titan at 11:38:11 UTC at a velocity of 15 feet per second (4.54 meters per second). Landing coordinates were 192.32 degrees west longitude and 10.25 degrees south latitude, about 4 miles (7 kilometers) from its target point.<\/p>\n<p>A problem in the communications program limited the number of images that Huygens transmitted to Cassini, from about 700 to 376. Yet, to the excitement of planetary scientists back on Earth, it continued its transmissions for another three hours and 10 minutes. During this time it transmitted a view of its surroundings (224 images of the same view).<\/p>\n<p>Huygens appears to have landed on a surface resembling sand made of ice grains. Surface pictures showed a flat plain littered with pebbles as well as evidence of liquid acting on the terrain in the recent past. Subsequent data confirmed the existence of liquid hydrocarbon lakes in the polar regions of Titan.<\/p>\n<\/blockquote>\n<h3>Huygens images of Titan\u2019s surface<\/h3>\n<p>Check out these views from Huygens as the spacecraft descended through Titan\u2019s hazy atmosphere and then made out the varied terrain below.<\/p>\n<figure id=\"attachment_497565\" aria-describedby=\"caption-attachment-497565\" style=\"width: 505px\" class=\"wp-caption alignnone\"><figcaption id=\"caption-attachment-497565\" class=\"wp-caption-text\">Here are 6 fisheye views that Huygens captured on its descent through Titan\u2019s atmosphere and to the surface.

Europa Clipper will arrive at Europa in 2030 and JUICE will reach the Jovian moons in 2031. The Europa Clipper mission will only perform flybys of Europa, no landing. But, interestingly, both Europa Clipper and JUICE will end their missions by deliberately crashing into Ganymede. ESA said:<\/p>\n<blockquote>\n<p>\u2026 there is the possibility that \u2013 depending on the missions\u2019 end dates \u2013 one spacecraft might have the chance to observe the effects of the other\u2019s impact. <\/p>\n<\/blockquote>\n<p>Bottom line: On January 14, 2005, the Huygens spacecraft descended through the atmosphere of Saturn\u2019s moon Titan and landed on its surface.
