The rings of Saturn have puzzled astronomers since Galileo Galilei discovered them with his telescope in 1610.They’re incredibly thin. The main rings are generally only about 30 feet (10 meters) thick, though parts of the main and other rings can be several kilometers thick. The rings are made of dusty ice, in the form of boulder-sized and smaller chunks that gently collide with each other as they orbit around Saturn. Saturn’s gravitational field constantly disrupts these ice chunks, keeping them spread out and preventing them from combining to form a moon.(Video credit: NASA)

The Day the Earth Smiled

In this rare image taken on July 19, 2013, the wide-angle camera on NASA’s Cassini spacecraft has captured Saturn’s rings and our planet Earth and its moon in the same frame. It is only one footprint in a mosaic of 33 footprints covering the entire Saturn ring system (including Saturn itself).  At each footprint, images were taken in different spectral filters for a total of 323 images: some were taken for scientific purposes and some to produce a natural color mosaic.  This is the only wide-angle footprint that has the Earth-moon system in it.
The dark side of Saturn, its bright limb, the main rings, the F ring, and the G and E rings are clearly seen; the limb of Saturn and the F ring are overexposed. The “breaks” in the brightness of Saturn’s limb are due to the shadows of the rings on the globe of Saturn, preventing sunlight from shining through the atmosphere in those regions.  The E and G rings have been brightened for better visibility.
Earth, which is 898 million miles (1.44 billion kilometers) away in this image, appears as a blue dot at center right; the moon can be seen as a fainter protrusion off its right side. An arrow indicates their location in the annotated version. (The two are clearly seen as separate objects in the accompanying narrow angle frame: PIA14949.) The other bright dots nearby are stars.
This is only the third time ever that Earth has been imaged from the outer solar system. The acquisition of this image, along with the accompanying composite narrow- and wide-angle image of Earth and the moon and the full mosaic from which both are taken, marked the first time that inhabitants of Earth knew in advance that their planet was being imaged. That opportunity allowed people around the world to join together in social events to celebrate the occasion.

Looking in the mirror from 898,410,414 miles away…
NASA has just released a raw edition of Friday’s photo of Earth and the moon, as seen from the Cassini spacecraft currently orbiting Saturn.
From out there, we look like stars. 
Just a tip, NASA: We’re gonna have to give it a better name than “N00213959.jpg”. Maybe “Pale Blue Sparkle”?
(hi-res at NASA website, a more processed version is sure to come… stay tuned)

Something great, something big, something very special that’s never happened before is about to happen!

On July 19, 2013, NASA’s Cassini spacecraft will be turned to image Saturn and its entire ring system during a total eclipse of the sun, as it has done twice before during its previous 9 years in orbit. But this time will be very different. This time, the images to be collected will capture, in natural color, a glimpse of our own planet next to Saturn and its rings on a day that will be the first time Earthlings know in advance their picture will be taken from a billion miles away. A full end-to-end mosaic of images of the ring system will be acquired over 4 hours on July 19. The Earth will be captured in a series of images taken between 21:27 to 21:42 UTC on that day, or 14:27 and 14:42 Pacific Daylight Time.

It will be a day for people all over the globe to celebrate together the extraordinary achievements that have made such an interplanetary photo session possible. And it will be a day to celebrate life on the Pale Blue Dot. Read the press release via CICLOPS.ORG.

The graphics shown below illustrate the position of our planet relative to Saturn, and the portion of Earth that will be illuminated at the time its pictures are captured.

Carolyn Porco: This is Saturn | TED

Carolyn Porco: Could a Saturn moon harbor life? | TED

Planetary scientist Carolyn Porco studies and interprets the photos from the Cassini-Huygens mission, orbiting Saturn and its largest moon, Titan. She and a team of scientists from NASA and the European Space Agency have been analyzing the images that Cassini has been sending back since it left Earth in 1999. They’ve found many new rings and four new moons (so far). And they’ve produced breathtaking images and animations of the stormy face of Saturn, its busy rings, and its jumble of moons and moonlets.

Back in the mid-1980s, while still working on her doctorate, Porco was drafted onto a team at JPL that was crunching the mountains of data coming back from the Voyager fly-by of Saturn. Her work on the planet’s “ringlets,” and on a spoke pattern noticed in the rings, made an important connection between Saturn’s rings and its magnetic field — and cemented her connection with Saturn.

Her ongoing work at the Cassini Imaging Central Laboratory for Operations (CICLOPs) has two goals: to process and interpret the Cassini images for other scientists, and to make sure the images — in all their breathtaking poetry and mystery and sheer Save-Image-As-Desktop awesomeness — connect with the general public. She is an advocate for the exploration and understanding of planetary space, and her frequent talks (as well as her “Captain’s Log” memos on the CICLOPS website) speak to everyone, scientist and nonscientist alike.

Still Curious? Watch Carolyn again, this time, LEGO-fied! and watch a conversation with Carolyn, as she discusses the Saturn and Cassini Mission with astrophysicist and curator, Mike Shara of the American Museum of Natural History during the 217th American Astronomical Society meeting in Seattle, Washington

“Imagine the day when we might journey to the Saturnine system, and visit the Enceladus interplanetary geyser park, just because we can.”

I love this woman.

You guys like Saturn, right? Here’s a whole gallery of Saturn GIFs, from rings to moons, captured by the Cassini spacecraft. They’re part modern art and part science.

Next to the Voyager twins, I think Cassini might be the best satellite NASA ever launched. Certainly takes the best pictures. Tumblr’s own staceythinx  has an iPad app called Cassini HD that features even more photos, plus color, plus science.

From Cassini: A splendor seldom seen




December 20, 2012 — The spacecraft has delivered another glorious backlit view of Saturn and its rings.
NASA’s Cassini spacecraft, in orbit around Saturn for more than eight years, has delivered another glorious backlit view of the planet Saturn and its rings.On October 17, 2012, during its 174th orbit around the gas giant, Cassini was deliberately positioned within Saturn’s shadow, a perfect location from which to look in the direction of the Sun and take a backlit view of the rings and the dark side of the planet. Looking back toward the Sun is a geometry referred to by planetary scientists as “high solar phase” — near the center of the target’s shadow is the highest phase possible. This is a scientifically advantageous and coveted viewing position as it can reveal details about both the rings and atmosphere that cannot be seen in lower solar phase.The last time Cassini had such an unusual perspective on Saturn and its rings, at sufficient distance and with sufficient time to make a full system mosaic, occurred in September 2006 when it captured a mosaic, processed to look like natural color, entitled “In Saturn’s Shadow-The Pale Blue Dot.” In that mosaic, planet Earth put in a special appearance, making “In Saturn’s Shadow” one of the most popular Cassini images to date.The mosaic being released today by the mission and the imaging team does not contain Earth — along with the Sun, our planet is hidden behind Saturn. However, it was taken when Cassini was closer to Saturn and therefore shows more detail in the rings than the one taken in 2006.“Of all the many glorious images we have received from Saturn, none are more strikingly unusual than those taken from Saturn’s shadow,” said Carolyn Porco, Cassini’s imaging team lead based at the Space Science Institute in Boulder, Colorado. “They unveil a rare splendor seldom seen anywhere else in our solar system.”

Encountering Hyperion
This movie sequence provides the record of Cassini’s first close brush with Hyperion, Saturn’s chaotically tumbling moon. As the spacecraft whizzes past, Hyperion’s unusual shape is most apparent. The jagged outlines are indicators of large impacts chipping away at Hyperion’s shape as a sculptor does to marble.Hyperion’s unusual dimensions are 328 by 260 by 214 kilometers (204 by 162 by 132 miles).These Cassini images are the best views yet of one of the large, low density objects that orbit Saturn. Hyperion is close to the size limit where, like a child compacting a snowball, internal pressure due to the moon’s gravity will begin to crush weak materials like ice, closing pore spaces and eventually creating a more spherical shape.However, this moon has a very irregular shape and preliminary estimates of its density show that it is only about 60 percent as dense as solid water ice. This suggests that much of its interior (40 percent or more) must be empty space.The low density further suggests that Hyperion is mostly made of water ice, with a low rock and metal content. If the moon had significant higher density components, its implied porosity would be significantly higher than 50 percent. The dark material on the surface is therefore likely a minor component, possibly originating from impacts of dark material, as seen on Iapetus.Hyperion’s elliptical orbit and irregular shape influence its chaotic tumbling. Further, because it is in a resonance orbit with the giant moon Titan, impact debris ejected with sufficient energy does not come to rest again on Hyperion. Instead, debris is tugged gravitationally into Titan’s orbit, where it impacts the large smoggy moon.This series of 25 images was taken over a period of nearly two and a half days, between June 9 and June 11, 2005, as Cassini’s orbit took it close to Hyperion.

While selecting images to include in our Cassini HD app I came across some great gifs. Unfortunately, I couldn’t include them in the app, so I’ll be posting them here instead. 

Saturn’s moon Mimas will never not look exactly like the Death Star, especially when it’s moving.
