Its clarity is an excellent test of atmospheric steadiness and the telescope's optical quality. And never stop exploring your options. 8 Farther out in the solar system, scientists have long had their eyes set on exploring Uranus and Neptune. The Cassini–Huygens space-research mission , commonly called Cassini, involved a collaboration between NASA, the European Space Agency (ESA), and the Italian Space Agency (ASI) to send a space probe to study the planet Saturn and its system, including its rings and natural satellites. Dr. Alan Smale (Director), within the the region. The first map showing the global geology of Saturn's largest moon, Titan, has been completed and fully reveals a dynamic world of dunes, lakes, plains, craters and other terrains. Cassini expanded our understanding of the kinds of worlds where life might exist. First landing in the outer solar system. NASA's Cassini spacecraft has detected dust storms on Saturn's largest moon, making Titan the third Solar System body where such storms have been observed. Titan visible near 10:00 position, north up, mirror reverse image. ", "Stay close to subjects that fascinate you personally, but also ask why is the subject important. In Gian Domenico Cassini …who, among others, discovered the Cassini Division, the dark gap between the rings A and B of Saturn; he also discovered four of Saturn’s moons. Cassini-Huygens revealed Titan to be one of the most Earth-like worlds we’ve encountered and shed light on the history of our home planet. Lessons learned during Cassini's mission are being applied in planning NASA's Europa Clipper mission, planned for launch in the 2020s. mission, planned for launch in the 2020s. It is almost as wide as the planet Mercury. We estimate the ability of Saturn's satellites to open other gaps in the rings. The Cassini mission revealed a surprising feature emerging at Saturn's northern pole as it nears summertime: a warming, high-altitude vortex with a hexagonal shape, akin to the famous hexagon seen deeper down in Saturn's clouds. The following week was dedicated to PSG #75, the Cassini Project Science Group meeting at JPL. NASA Official: The plainest is the black Cassini Division between the A and B rings. 2003) Saturn is 8+ A.U. Cassini and the Division in Saturn's Ring. Cassini revealed in great detail the true wonders of Saturn, a giant world ruled by raging storms and delicate harmonies of gravity. Two important meetings of scientists took center stage for the Cassini team this month. The Cassini Division is a distance between two of Saturn’s rings, A and B. Math is the language of science. All will serve you well regardless of what you do. Research Center (HEASARC), Amanda Barnett Just hang on in there. Get the latest updates on NASA missions, watch NASA TV live, and learn about our quest to reveal the unknown and benefit all humankind. Lying between 1.95 and 2.02 Saturn radii and not devoid of particles, the Cassini division exhibits complicated variations in optical depth, with an average value of 0.1. The shadows of Saturn's three bright rings and Tethys are cast onto the cloud tops. : the dark region between the two brightest rings of Saturn A sequence of smoothly undulating brightness fluctuations is observed in the outer Cassini division within a band located between Cassini division120,000 and 121,900 km from the centre of Saturn. Former Director for Solar System Exploration. Cassini’s long mission enabled us to observe weather and seasonal changes on another planet. ", "Sometimes you have to tackle a problem from many different ways to understand it and you should never be afraid to ask for help. Saturn's ring system has gaps throughout it, though only a few of these gaps traveled since launch (7.9 billion kilometers). Scientists have developed a new prediction of the shape of the bubble surrounding our solar system. The length of a day on Saturn: 10 hours, 33 minutes and 38 seconds. Before the mission ended, Cassini’s was an already powerful influence on future exploration. Get lots of good chemistry, physics and math background in college. News, images and videos from the Cassini mission, which explored Saturn and its moons from 2004 to 2017. Very good views of the Cassini division, some cloud bands, and shading in north polar region. This site is maintained by the Planetary Science Communications team at, Cassini carried a passenger to the Saturn system, the European. 3 ", "There will be times when you don't think you are doing the right thing, but don't make any hasty decisions. NASA.gov brings you the latest images, videos and news from America's space agency. The StarChild site is a service of the "Be curious about everything -- take every opportunity that presents itself to learn new things. In 1675, Cassini discovered a narrow gap that splits Saturn's ring system into two parts, and the gap has since been known as the "Cassini Division." Whitlock "Science and math are fascinating and fundamental. Cassini was, in a sense, a time machine. Cassini carried a passenger to the Saturn system, the European Huygens probe—the first human-made object to land on a world in the distant outer solar system. ", "His spirit will continue to inspire us as we continue our quest to understand the Universe. Its clarity is an excellent test of atmospheric steadiness and the telescope's optical quality. Shadings within the rings are even easier to discern. The alphabetical designation of Saturn's rings is historically based on their order of discovery ; rings A and B are the bright rings separated by the Cassini division. StarChild Authors: The StarChild Team In order of increasing distance from Saturn, the seven main rings run D,C,B,A,F,G,E. Be persistent. Saturn’s nearby moon, Mimas. And so, to protect moons of Saturn that could have conditions suitable for life, Cassini was sent on a daring final mission that would seal its fate. Cassini scientists have found the ingredients for amino acids condensed onto ice grains emitted by Saturn's sixth-largest moon. The B-ring is the most opaque of Saturn's rings. I've been here ever since. (search for Cassini for all available data), Impact Craters Reveal Details of Titan's Dynamic Surface Weathering, Infrared Eyes on Enceladus: Hints of Fresh Ice in Northern Hemisphere, More about Richard "Rick" Grammier (1955 - 2011), Are Ocean Planets Common? Cassini revealed Saturn’s moons to be unique worlds with their own stories to tell. This is the “gap” you’ll see when you look at Saturn through a telescope, or images of Saturn taken through a telescope, but it’s no gap—there is ring material in there. Mimas orbits Saturn once every 22 hours, and would-be particles in the Cassini Division would orbit once every 11-12 hours, so that the ratio of the orbit periods is close to 2 to 1. After a series of nearly two dozen nail-biting dives between the planet and its icy rings, Cassini plunged into Saturn’s atmosphere on Sept. 15, 2017, returning science data to the very end. 4 these gaps is called the Cassini division, after its French discoverer Jean Most of my heroes have succeeded against the odds in some way. ", "Science and math are part natural gifts and part practice. Cassini was, in a sense, a time machine. The view through the much narrower Encke Division… A study using Cassini data reveals a warming, high-altitude, hexagonal vortex emerging at Saturn’s northern pole. Cassini represented a staggering achievement of human and technical complexity, finding innovative ways to use the spacecraft. StarChild Project Leader: Dr. Laura A.
