From a distance, Saturn�s rings look like a sheer sheet, but peer up close and you can see that impression is a mistake.
Shadows from rubble believed to be two miles (3.2 kilometers) high are throwing shadows upon the planet�s
B ring in this image from the Cassini spacecraft.

The Cassini Spacecraft

Artist's impression of Cassini-Huygens The Cassini-Huygens spacecraft is one of the largest, heaviest and most complex interplanetary spacecraft ever built.
Of all interplanetary spacecraft, only the two Phobos spacecraft sent to Mars by the former Soviet Union were heavier.
Loaded with an array of powerful instruments and cameras, the spacecraft is capable of taking accurate measurements and detailed
images in a variety of atmospheric conditions and light spectra.

The Most Spectacular Photo (and GIF!) of Saturn Ever Taken !!

iPhone cameras are good � but they aren't as good as this.
NASA's Cassini spacecraft captured this view as it approached Saturn in early 2011.
The GIF is so beautiful that it's bubbled back up to the front page of Reddit today!

A Brighter Moon

Although Dione (near) and Enceladus (far) are composed of nearly the same materials,
Enceladus has a considerably higher reflectivity than Dione.

Saturn's Northern Polar Vortex

Polar Cyclones on Saturn Form From Smaller Storms

In a paper published in the journal Nature Geoscience (June 15th 2015), atmospheric scientists at MIT have proposed a mechanism
for Saturn’s polar cyclones.
Over time, small, short-lived thunderstorms across the planet are thought to build up angular momentum (or spin) within the atmosphere,
ultimately stirring up a long-lasting vortex at the poles.
Simulations carried out by Morgan O’Neill and colleagues at MIT’s Department of Earth, Atmospheric and Planetary Sciences (EAPS)
show that small isolated thunderstorms pull material in Saturn's atmosphere towards the poles, accumulating atmospheric energy which
then generates a much larger, long-lasting polar cyclone.
The research concludes that whether or not a polar cyclone forms depends on the total energy within a planet’s atmosphere,
and the average size of its thunderstorms, relative to the size of the planet. Larger thunderstorms are more likely to ultimately create the north polar cyclone that has been observed by NASA's Cassini spacecraft orbiting Saturn. Cassini Image Credit : NASA/JPL-Caltech/Space Science Institute.

Cassini's Last Phase: Mission to Saturn's rings

Image: Cassini crosses Saturn’s F ring once on each of its 20 Ring-Grazing Orbits, shown here in tan and lasting from late November 2016 to April 2017. Blue represents the extended solstice mission orbits, which precede the ring-grazing phase. Credit: JPL. That grazing will include two passes directly through a tenuous ring created by meteor strikes on the small moons Janus and Epimetheus. Each orbit will cross the ring plane just outside the F ring, considered to be the boundary of the main ring system, with Cassini actually moving through the outer edges of the F ring in April. Here the science should be particularly interesting — the 800-kilometer wide F ring is malleable, developing and dispersing filament-like structures, dark channels and streamers over short periods of time.

Image: Saturn’s rings were named alphabetically in the order they were discovered. The narrow F ring marks the outer boundary of the main ring system. Credit: NASA/JPL-Caltech/Space Science Institute. The distances involved in this phase of the mission are worth noting. The new orbits will take the craft within 90,000 kilometers of the planet’s cloud tops, but the Grand Finale phase, scheduled to begin next April, closes to within 1628 kilometers. This should be breathtaking, for the craft will move again and again through the gap between Saturn and the rings before making its final plunge into the atmosphere on September 15. Preparations for this final phase begin with a main engine burn on December 4. This is an engine that has served us well — this will be its 183rd burn — but the remainder of the mission will be handled with thrusters.

During it�s 2006 flyby of Titan, the Cassini Space Probe captured some of the most detailed images of Saturn�s largest moon.
Amongst them was one showing the lofty cloud formations over Titan�s north pole (shown above).
Interestingly enough, these cloud formations bear a strong resemblance to those that are seen in Earth�s own polar stratosphere.

TITAN: INFRARED Specular Spectacular!

This near-infrared, color mosaic from NASA's Cassini spacecraft shows the sun glinting off of Titan's north polar seas.
While Cassini has captured, separately, views of the polar seas (see PIA17470) and the sun glinting off of them (see PIA12481 and PIA18433)
in the past, this is the first time both have been seen together in the same view.

Image: NASA/JPL/University of Arizona/University of Idaho This composite infra red image of Saturn’s moon Titan was taken on 13 November by NASA’s Cassini probe.
The spacecraft’s visual and infrared mapping spectrometer (VIMS) instrument made these observations,
in which blue represents wavelengths centered at 1.3 microns, green represents 2.0 microns, and red represents 5.0 microns.
A view at visible wavelengths (centered around 0.5 microns) would show only Titan’s hazy atmosphere. The near-infrared wavelengths
in this image allow Cassini’s vision to penetrate the haze and reveal the moon’s surface.

TITAN: The Smog covered Moon

Titan is Saturn�s largest moon and is constantly surprising scientists as the Cassini
spacecraft probes under its thick atmosphere. Take its dunes, for example, which are huge and pointed the wrong way.
Why are they pointing opposite to the prevailing east-west winds? It happens during
two rare wind reversals during a single Saturn year (30 Earth years), investigators suggest.

Another group of researchers investigated the formation of Titan's dunes using data from the Cassini spacecraft.
Their work suggests that the dunes may have taken as long as 3,000 Saturn years to form (the equivalent of 90,000 Earth years).
According to a statement from Texas A&M, the formation of the dunes may be influenced by changes in Saturn's orbit.

Science Flooded Canyons Discovered on Saturn's Mysterious Moon Titan

NASA's Cassini spacecraft pinged the surface of Titan with microwaves, finding that some channels are deep, steep-sided canyons
filled with liquid hydrocarbons. One such feature is Vid Flumina, the branching network of narrow lines in the upper-left quadr NASA
just announced that it has discovered flooded canyons on Saturn's moon Titan, a world famous for vast seas and lakes as well as
torrential downpours of methane and other hydrocarbons. The findings, recently published in the journal Geophysical Research Letters,
suggest complex and diverse geologic activity on the distant moon similar to what we have on Earth, despite the substantial differences
between the two worlds.

Titan Touchdown

Published on Jan 11, 2017 On Jan. 14, 2005, ESA's Huygens probe made its descent to the surface of Saturn's hazy moon, Titan. Carried to Saturn by NASA's Cassini spacecraft, Huygens made the most distant landing ever on another world, and the only landing on a body in the outer solar system. This video uses actual images taken by the probe during its two-and-a-half hour fall under its parachutes. Huygens was a signature achievement of the international Cassini-Huygens mission, which will conclude on Sept. 15, 2017, when Cassini plunges into Saturn's atmosphere.

Titan's last Image From Cassini- Titan Farewell
See dramatic clouds streak across Saturn's moon Titan

See dramatic clouds streak across Saturn's moon Titan More The Cassinis spacecraft's farewell tour of Saturn may be focused on the strangely empty space between the planet and its rings, but it's still taking time to do some local sightseeing. Cassini snapped this image of Saturn's largest moon Titan on May 7 from a distance of 303,000 miles (488,000 kilometers) away. The bright streaks are methane clouds, while the darker splotches seen toward the top are the moon's fascinating hydrocarbon lakes. NASA released two versions of the image on Tuesday with different levels of enhancement. One makes the bands and seas really pop out, while the other offers a softer, more ethereal view of the same scene. The Cassini mission, which launched in 1997, is scheduled

Saxton (NRAO/AUI/NSF); NASA. An interesting thought, because the three signals Palmer and team found in millimeter wavelength spectra from ALMA observations in 2014 confirm what Cassini had already hinted at, which in turn reinforce laboratory simulations of Titan’s atmosphere. A surface rife with pools of hydrocarbons — and Titan is a place of methane rains, rivers and seas — could allow molecules of vinyl cyanide to link together, forming membranes that resemble the lipid-based cell membranes found on Earth. Titan’s complex organic molecules along with its nitrogen atmosphere and the presence of carbon-based molecules are provocative ingredients.

Dragonfly: A Proposal to Explore Titan, Saturn's Largest Moon, via Quadcopter

A team from the Johns Hopkins Applied Physics Laboratory in Laurel, Maryland is proposing an instrumented, radioisotope-powered dual-quadcopter to explore Titan, one of a number of "ocean worlds" in our solar system that hold the ingredients for life. Dragonfly, a New Frontiers-class mission concept APL is proposing to NASA, would explore Titan's surface. The moon is known to be covered with rich organic material, which is undergoing chemical processes that might be similar to those on early Earth, before life developed. APL's Peter Bedini, program manager for Dragonfly, details the proposal's engineering and science.

Saturn's Moon Mimas

A thin sliver of Mimas is illuminated, the long shadows showing off its many craters,
indicators of the moon's violent history. The most famous evidence of a collision on Mimas (246 miles, or 396 kilometers across)
is the crater Herschel that gives Mimas its Death Star-like appearance. See PIA12568 for more on Herschel.
This view looks toward the anti-Saturn hemisphere of Mimas. North on Mimas is up and rotated 40 degrees to the right.
The image was taken in visible light with the Cassini spacecraft narrow-angle camera on May 20, 2013.
The view was acquired at a distance of approximately 100,000 miles (200,000 kilometers) from Mimas and at a
Sun-Mimas-spacecraft, or phase, angle of 130 degrees. Image scale is 4,000 feet (1 kilometer) per pixel.

Could there be an ocean hidden somewhere in that Death Star-like picture? This is an image of Mimas, a moon of Saturn,
and just yesterday (Oct. 15) newly released data from the Cassini spacecraft suggests there are big liquid reservoirs underneath its surface.
�The amount of the to-and-fro motion indicates that Mimas� interior is not uniform. These wobbles can be produced
if the moon contains a weirdly shaped, rocky core or if a sub-surface ocean exists beneath its icy shell,� said Cornell University
in a press release. More flybys with the Cassini spacecraft will be required to learn more about what lies beneath.

Ever taken a balloon and rubbed it against your hair? That�s an example of electrostatic charging,
which you see as the balloon briefly attracts strands of hair against your head.
Turns out a similar process is taking place on Saturn�s moon Hyperion. More astounding,
it wasn�t until recently that scientists saw a curious effect on the Cassini spacecraft in 2005.

It’s chaos at Saturn’s moon Hyperion

Image: NASA/JPL-Caltech/Space Science Institute. The moon Hyperion tumbles as it orbits Saturn. Hyperion’s (270 kilometres or 168 miles across) spin axis has a chaotic orientation in time, meaning that it is essentially impossible to predict how the moon will be spinning in the future. So far, scientists only know of a few bodies with such chaotic spins. The image was taken in green light with the Cassini spacecraft narrow-angle camera on 22 August 2016.

Saturn's Moon Enceladus

Enceladus: Infographics


Artist's rendering of possible hydrothermal activity that may be taking place on and under the seafloor of Enceladus. Image Credit: NASA/JPL


Image: The graphic shows water from the ocean circulating through the seafloor, where it is heated and interacts chemically with the rock. This warm water, laden with minerals and dissolved gases (including hydrogen and possibly methane) then pours into the ocean creating chimney-like vents. The hydrogen measurements were made using Cassini’s Ion and Neutral Mass Spectrometer, or INMS, instrument, which sniffs gases to determine their composition. The finding is an independent line of evidence that hydrothermal activity is taking place in the Enceladus ocean. Previous results from Cassini’s Cosmic Dust Analyzer instrument, published in March 2015, suggested hot water is interacting with rock beneath the ocean; the new findings support that conclusion and indicate that the rock is reduced in its geochemistry. With the discovery of hydrogen gas, scientists can now conclude that there is a source of chemical free energy in Enceladus’ ocean. Credit: NASA/JPL-Caltech/Southwest Research Institute.

Ever since the Cassini space probe conducted its first flyby of Enceladus in 2005,
the strange Saturnian moon has provided us with a treasure trove of images and scientific wonders.
These include the jets of icy water vapor periodically bursting from its south pole, the possibility of an interior ocean �
which may even harbor life � and the strange green-blue stripes located around the south pole.

SCIENCE On a moon of Saturn, a boiling ocean?
Hot springs on Saturn's ice-encrusted moon Enceladus suggests that parts of
the ocean locked beneath the ice is at near-boiling temperatures.

Parcheta�s research recently attracted the attention of visitors to National Geographic�s website,
who voted her #2 in a list of �great explorers� on the Expedition Granted campaign.


Hot springs on Saturn's icy moon Enceladus suggest that the floor of the satellite's subsurface ocean
may be home to near-boiling temperatures, researchers say.
This finding is the first evidence of active hydrothermal vents beyond the oceans of Earth.
Moreover, conditions deep under the icy surface of Enceladus could be similar to those that gave rise
to the first life on Earth, the researchers reported in the new study.

NASA's Cassini spacecraft captured this view of Saturn's moon Enceladus that shows wrinkled plains
that are remarkably youthful in appearance, being generally free of large impact craters. When viewed with north pointing up, as in this image, the day-night boundary line (or terminator)
cuts diagonally across Enceladus, with Saturn approaching its northern summer solstice.
The lit portion on all of Saturn's large, icy moons, including Enceladus
(313 miles or 504 kilometers across) and Saturn itself, is now centered on their northern hemispheres.
This change of season, coupled with a new spacecraft trajectory, has progressively revealed new terrains
compared to when Cassini arrived in 2004 (see PIA06547), when the southern hemisphere was more illuminated.

If you hang out in Saturn�s intense magnetic environment for a while, it�s going to leave a mark.
That�s one conclusion from scientists who proudly released new maps yesterday (Dec. 9)
of the planet�s icy moons, showing dark blotches on the surfaces of Dione, Rhea, and Tethys.

A close look at Saturn's closest moons

Saturn's innermost moons: Pan, Daphnis, Atlas, Prometheus, Pandora, Epimetheus, Janus, and Mimas, to scale
The eight innermost moons of Saturn, in color images collected by Cassini between June 7, 2005, and July 5, 2010.
Pan and Daphnis (top left small moons) orbit within the Encke and Keeler gaps in the rings;
Atlas (below Pan and Daphnis) orbits at the outer edge of the main rings. To their right are Prometheus and Pandora;
Prometheus orbits just inside and Pandora just outside the F ring. Below them are Epimetheus (left) and Janus (right),
which trade positions every four years, averaging out to the same distance from Saturn. Mimas orbits considerably farther away,
but its gravitational effects influence the positions of gaps and waves within the rings.
At full resolution, the montage has a scale of 500 meters per pixel.

Janus Stands Alone

uch as its name implies, tiny Epimetheus (Greek for hindsight) was discovered in hindsight.
Astronomers originally thought that Janus and Epithemeus were the same object.
Only later did astronomers realize that there are in fact two bodies sharing the same orbit!
Janus (111 miles or 179 kilometers across) and Epimetheus (70 miles or 113 kilometers)
have the same average distance from Saturn, but they take turns being a little closer or a little farther from Saturn,
swapping positions approximately every 4 years. See PIA08348 for more.
This view looks toward the sunlit side of the rings from about 29 degrees above the ringplane.
The image was taken in visible light with the Cassini spacecraft narrow-angle camera on Jan. 1, 2015.
The view was acquired at a distance of approximately 1.8 million miles (2.9 million kilometers)
from Epimetheus and at a Sun-Epimetheus-spacecraft, or phase, angle of 89 degrees.
Image scale is 11 miles (17 kilometers) per pixel.

Saturn's Moon Tethys

Like most moons in the solar system, Tethys is covered by impact craters.
Some craters bear witness to incredibly violent events, such as the crater Odysseus
(seen here at the right of the image). The image was taken in visible light with the
Cassini spacecraft narrow-angle camera on April 11, 2015.

Saturn's Moon DIONE

This is a photo of Dione, one of Saturn's moons. Just like the planet's most stunning images,
this picture was also captured by NASA's and ESA's Cassini spacecraft, as it flew by on June 16, 2015.
The vessel, which has been orbiting Saturn for over a decade, took the pictures in visible light
using a narrow-angle camera at an altitude of 321 miles from the moon's pockmarked surface.
While that's pretty close, the closest flyby yet happened in 2011, when Cassini flew by Dione at an altitude of 62 miles.

The image above was taken from 48,000 miles away, with Saturn and its rings visible in the background
and Enceladus making a cameo on the upper right portion of the pic. Enceladus is another Saturnian moon,
which astronomers believe might have warm waters, chemicals and minerals that could foster life.
Cassini's slated to pass real close to it soon -- as close as 30 miles from its surface --
and will likely take images of the icy satellite, as well.

Chasms on Dione

While not bursting with activity like its system sister Enceladus, the surface of Dione is definitely not boring.
Some parts of the surface are covered by linear features, called chasmata, which provide dramatic contrast to the round impact
craters that typically cover moons. The bright network of fractures on Dione (698 miles or 1123 kilometers across) was seen originally at poor resolution in
Voyager images and was labeled as "wispy terrain." The nature of this terrain was unclear until Cassini showed that they weren't
surface deposits of frost, as some had suspected, but rather a pattern of bright icy cliffs among myriad fractures.
One possibility is that this stress pattern may be related to Dione's orbital evolution and the effect of tidal stresses over time. This view looks toward the trailing hemisphere of Dione. North on Dione is up. The image was taken in visible light with the
Cassini spacecraft narrow-angle camera on April 11, 2015. The view was acquired at a distance of approximately 68,000 miles (110,000 kilometers) from Dione.

Dione Dwarfing Rhea

Is Dione (698 miles or 1123 kilometers across) suddenly larger than Rhea (949 miles or 1527 kilometers across)? No, of course not. Cassini simply captured an image
when Dione was much closer to the camera, making the moon appear much bigger than her larger sister moon.
Besides their beauty, images like these can help Cassini's navigators determine exactly where the spacecraft
is and confirm that it's on course.
This view looks toward the trailing hemisphere of Dione. North on Dione is up. The image was taken in visible light with the Cassini
spacecraft narrow-angle camera on April 11, 2015.
The view was obtained at a distance of approximately 68,000 miles (110,000 kilometers) from Dione and at a Sun-Dione-spacecraft,
or phase, angle of 29 degrees. Image scale at Dione is 2,165 feet (660 meters) per pixel. Rhea was 300,000 miles (500,000 kilometers)
away at a phase (Sun-Rhea-spacecraft) angle of 30 degrees. The image scale at Rhea is 2 miles (3 kilometers) per pixel.

Electrical Circuit Between Saturn and Enceladus

This artist's concept shows a glowing patch of ultraviolet light near Saturn's north pole that occurs at the "footprint"
of the magnetic connection between Saturn and its moon Enceladus. The footprint and magnetic field lines are not visible to the naked eye,
but were detected by the ultraviolet imaging spectrograph and the fields and particles instruments on NASA's Cassini spacecraft.
The footprint, newly discovered by Cassini, marks the presence of an electrical circuit that connects Saturn with Enceladus and
accelerates electrons and ions along the magnetic field lines. In this image, the footprint is in the white box marked on Saturn,
with the magnetic field lines in white and purple.

Saturn's Moon IAPETUS

A 300 Year Old Mystery Solved: Why Saturn's Moon Iapetus Is Half-Light, Half-Dark

Image CREDIT: NASA / JPL-Caltech / Space Science Institute / Cassini. Cassini developed a THEORY about this moon, now known as Iapetus.
He contended that first off, Iapetus must be two-toned, with one side significantly
lighter and brighter than the other, darker side, and that secondly, it must be tidally locked to Saturn,
so that the same side always faces it. Put this together and the “leading edge” of Iapetus
would have to be significantly fainter and darker than the trailing edge. If, that is, Cassini was right.

Both Hemispheres of IAPETUS

Image CREDIT: NASA / JPL / Space Science Institute. Iapetus was very much two-toned, with one hemisphere a factor of ten-to-twenty
times more reflective than the other. The situation was even more severe than Cassini
himself had ever imagined, as the delineation between light-and-dark hemispheres doesn’t
perfectly coincide with Iapetus’ orbit.

What’s This Ridge on Iapetus?

Published on Jul 20, 2015 The strangest feature on Iapetus is the equatorial ridge. What could possibly create a feature like this?

Image CREDIT: English Wikipedia user The Singing Badger. Iapetus, you see, is the outermost large moon of Saturn, orbiting twice
as far out as any of Saturn’s other moons. What appears to be some type of
dark debris that collected on the leading side — an effect similar to “bugs on a windshield”
— would be an awfully bizarre explanation, since it’s well outside of the other major players in Saturn’s system,

This new view of Saturn’s moon Pan is the closest yet, snapped by Cassini from a distance of 15,268 miles (24,572 km) on March 7, 2017. Pan measures 22 miles wide by 14 miles across and displays a number of small craters along with parallel ridges and grooves. Its broad, thinner equatorial ridge displays fine, parallel striations. Credit: NASA/JPL/Space Science Institute

A side view of Pan better shows its thin and wavy ridge likely built up through the accumulation of particles grabbed from Saturn’s rings. The ridge is between 0.9 and 2.5 miles (1-4 km) thick. Credit: NASA/JPL/Space Science Institute

As Pan moves along the Encke Gap its gravity creates ripples in Saturn’s A-ring. Credit:NASA/JPL/Space Science Institute

Pan casts its shadow on Saturn’s A-ring from within the 200-mile-wide (325 km) Encke Gap, which is maintained by the presence of the moon. Pan shares the gap with several diffuse ringlets from which it may still be gathering additional material around its equatorial ridge. Credit: NASA/JPL/Space Science Institute

Pan and Altas (25×22 miles) orbit within Saturn’s ring plane and may both be fragments from a larger moon breakup that created Saturn’s rings. Both have swept up material from the rings to form equatorial ridges. Credit: NASA/JPL/Space Science Institute
