Turning a midsummer night's dream into reality, NASA's Cassini spacecraft began its new mission extension -- the Cassini Solstice Mission -- on Monday. The mission extension will take Cassini a few months past Saturn's northern summer solstice (or midsummer) through September 2017. It will enable scientists to study seasonal changes and other long-term weather changes on Saturn and its moons. Cassini had arrived just after Saturn's northern winter solstice in 2004, and the extension continues...

NASA's Cassini spacecraft has returned Saturnian moon images from its flyby late last week, revealing light and dark contrasts worthy of chiaroscuro painters like Caravaggio. The flyby on August 13 targeted the geyser moon Enceladus, but also brought Cassini close to two other moons--Tethys and Dione. The raw images include the best ones to date of Penelope crater on the icy moon Tethys . Penelope crater, which is 150 kilometers (90 miles) wide, is the second-largest crater on Tethys. Cassini...

NASA's Cassini spacecraft has successfully completed its flyby over the "tiger stripes" in the south polar region of Saturn's moon Enceladus and has sent back images of its passage. The spacecraft also targeted the moon Tethys. The tiger stripes are actually giant fissures that spew jets of water vapor and organic particles hundreds of kilometers, or miles, out into space. While the winter is darkening the moon's southern hemisphere, Cassini has its own version of "night vision goggles" --...

NASA's Cassini spacecraft started hunting for heat signatures at the "tiger stripes" in the dim south polar region of Saturn's moon Enceladus on Friday, Aug. 13. The closest approach will bring the spacecraft to within about 2,500 kilometers (1,600 miles) of the surface of Enceladus. The tiger stripes -- which are actually giant fissures that spew jets of water vapor and organic particles hundreds of kilometers, or miles, out into space - are hard to see in the visible-light spectrum because...

Space researchers illuminate "Ëœone of the most perplexing puzzles in planetary science' An international team of scientists led by Dr Jonathan Nichols of the University of Leicester has discovered that Saturn's aurora, an ethereal ultraviolet glow which illuminates Saturn's upper atmosphere near the poles, pulses roughly once per Saturnian day. The length of a Saturnian day has been under much discussion since it was discovered that the traditional "Ëœclock' used to...

Complex interactions between Saturn and its satellites have led scientists using NASA's Cassini spacecraft to a comprehensive model that could explain how oxygen may end up on the surface of Saturn's icy moon Titan. The presence of these oxygen atoms could potentially provide the basis for pre-biological chemistry. The interactions are captured in two papers, one led by John Cooper and another led by Edward Sittler, published in the journal Planetary and Space Science in late 2009. Cooper and...

NASA's Cassini spacecraft is on its way to a flyby of Saturn's largest moon, Titan, after capturing some stunning images of Enceladus. One view shows the hazy outline of Titan behind Saturn's rings, with the dark curve of Enceladus at the bottom. In other images, Enceladus put its craggy face forward, exhibiting some of the fractures and cratering that have made the Saturnian moon a favorite of both planetary scientists and outer-planet mission groupies. A view of Enceladus' terminator was...

About a month and a half after its last double flyby, NASA's Cassini spacecraft will be turning another double play this week, visiting the geyser moon Enceladus and the hazy moon Titan. The alignment of the moons means that Cassini can catch glimpses of these two contrasting worlds within less than 48 hours, with no maneuver in between. Cassini will make its closest approach to Enceladus late at night on May 17 Pacific time, which is in the early hours of May 18 UTC. The spacecraft will pass...

NASA's Cassini spacecraft successfully completed its 26-hour gravity observation at Saturn's moon Enceladus last week, sending back data scientists will use to understand the moon's interior composition and structure. The flyby took Cassini through the water-rich plume flaring out from Enceladus' south polar region, with a closest approach of about 100 kilometers (60 miles) occurring in the late afternoon of April 27, 2010, Pacific Time, or just after midnight April 28 UTC. A steady radio...

Jonathan Lunine's research involves spacecraft missions and the exploration of planets, moons and other celestial bodies in our solar system and beyond. Ever since he was 4 years old, Jonathan Lunine has had stars and planets on his mind. "I grew up in New York, close to the Hayden Planetarium. It was the time of the Apollo moon landings, and unmanned space exploration missions were getting under way," he said. "I wanted to be a part of that." On April 27, Lunine, a professor in the...

Saturn's moon Dione -- Dione is a moon of Saturn discovered by Giovanni Cassini in 1684. It is composed primarily of water ice, but as the densest of Saturn's moons (aside from Titan, whose density is increased by gravitational compression) it must have a considerable fraction of denser material like silicate rock in its interior. Though somewhat smaller, Dione is otherwise very similar to Rhea. They both have similar compositions, albedo features and varied terrain. Both have dissimilar...

Saturn's moon Enceladus -- Enceladus is a moon of Saturn discovered in 1789 by William Herschel. At least five different types of terrain have been identified on Enceladus. In addition to craters there are smooth plains and extensive linear cracks and ridges. At least some of the surface is relatively young, probably less than 100 million years. This means that Enceladus must have been active very recently with some sort of "water volcanism" or other process that renews the surface....

The Planet Saturn -- in astronomy, 6th planet from the sun. Astronomical and Physical Characteristics of Saturn Saturn's orbit lies between those of Jupiter and Uranus; its mean distance from the sun is c.886 million mi (1.43 billion km), almost twice that of Jupiter, and its period of revolution is about 291/2 years. Saturn appears in the sky as a yellow, starlike object of the first magnitude. When viewed through a telescope, it is seen as a golden sphere, crossed by a series of...
