Pretty picture: Meet Tethys

As regular readers will know, I make a lot of montages and comparisons of different worlds in the solar system. One of the tricks I use to make these montages look better is to try to select views that have similar phase -- meaning that a similar amount of the globe is lit in each one. Being at similar phase (and oriented so that the Sun appears to be coming from the same direction for all the objects) ties them all together compositionally.

So. I'm working on a project that involves such a montage of outer planet moons, and I just couldn't find a view of one of them -- Tethys, one of Saturn's mid-sized icy moons, similar in size to Dione and also, by the way, Charon and Ceres -- at a phase that matched the others. When I'm looking for pretty color versions of Cassini images, I always check Gordan Ugarkovic's Flickr stream, but he didn't seem to have one there either. So I fired off an email, and within a day Gordan had dug into the Cassini archives and pulled out the data to produce the very lovely high-resolution view below. Click to enlarge!

Global view of Tethys from Cassini

Taken by Cassini on October 14, 2009.

The view is a mosaic of four color images. Data were captured by Cassini on October 14, 2009 through infrared, green, and ultraviolet filters. Gordan processed this "natural-ish" color version from this more extended palette. The large crater near the center of the disk is Penelope; to the west of Penelope there is a north-south line of the three craters Phemius, Polyphemus, and Ajax. Antinous is the large crater far to the south of these. That "T" of craters is one of the things I use to tell Tethys from Dione or Rhea. Another diagnostic Tethys feature, the S-curve of Ithaca Chasma, is on the back side of Tethys from this perspective.

Why wasn't a processed version of this view available before? Because it's a color mosaic. We usually make color photos from space image data by combining three or four images taken through different filters. (Three if it's a straight red, green, blue combo; four if such a combo is overlaid on a sharper, higher-resolution image, often taken through a clear filter, or made by a super-resolution combination of other images.) We make mosaics by puzzle-piecing two or more images together. This view is a 2x2 mosaic, so there were a total of four tiles covering Tethys, each of which consisted of three or four different color filter images. That's 12 or 16 individual files to download, calibrate, clean, and compose -- a lot of work!

There are a lot of these color mosaics lying around in the Cassini data archives, waiting for someone to take the time to assemble them into beautiful portraits of mini planets...

(Thanks, Gordan!)

Подпочвенный океан Старого обнаружился немножко в другом месте

Зонд "Кассини" обнаружил гигантский океан под поверхностью Титана

Зонд "Кассини" обнаружил на Титане, самом крупном спутнике Сатурна, гигантский океан, занимающий всю площадь планеты и расположенный на глубине 100 километров от поверхности небесного тела, говорится в статье, опубликованной в журнале Science.

Cassini Finds Likely Subsurface Ocean on Saturn Moon

PASADENA, Calif. -- Data from NASA's Cassini spacecraft have revealed Saturn's moon Titan likely harbors a layer of liquid water under its ice shell.

Researchers saw a large amount of squeezing and stretching as the moon orbited Saturn. They deduced that if Titan were composed entirely of stiff rock, the gravitational attraction of Saturn would cause bulges, or solid "tides," on the moon only 3 feet (1 meter) in height. Spacecraft data show Saturn creates solid tides approximately 30 feet (10 meters) in height, which suggests Titan is not made entirely of solid rocky material. The finding appears in today's edition of the journal Science.

"Cassini's detection of large tides on Titan leads to the almost inescapable conclusion that there is a hidden ocean at depth," said Luciano Iess, the paper's lead author and a Cassini team member at the Sapienza University of Rome, Italy. "The search for water is an important goal in solar system exploration, and now we've spotted another place where it is abundant."

Titan takes only 16 days to orbit Saturn, and scientists were able to study the moon's shape at different parts of its orbit. Because Titan is not spherical, but slightly elongated like a football, its long axis grew when it was closer to Saturn. Eight days later, when Titan was farther from Saturn, it became less elongated and more nearly round. Cassini measured the gravitational effect of that squeeze and pull.

Scientists were not sure Cassini would be able to detect the bulges caused by Saturn's pull on Titan. By studying six close flybys of Titan from Feb. 27, 2006, to Feb. 18, 2011, researchers were able to determine the moon's internal structure by measuring variations in the gravitational pull of Titan using data returned to NASA's Deep Space Network (DSN).

"We were making ultrasensitive measurements, and thankfully Cassini and the DSN were able to maintain a very stable link," said Sami Asmar, a Cassini team member at NASA's Jet Propulsion Laboratory in Pasadena, Calif. "The tides on Titan pulled up by Saturn aren't huge compared to the pull the biggest planet, Jupiter, has on some of its moons. But, short of being able to drill on Titan's surface, the gravity measurements provide the best data we have of Titan's internal structure."

An ocean layer does not have to be huge or deep to create these tides. A liquid layer between the external, deformable shell and a solid mantle would enable Titan to bulge and compress as it orbits Saturn. Because Titan's surface is mostly made of water ice, which is abundant in moons of the outer solar system, scientists infer Titan's ocean is likely mostly liquid water.

On Earth, tides result from the gravitational attraction of the moon and sun pulling on our surface oceans. In the open oceans, those can be as high as two feet (60 centimeters). While water is easier to move, the gravitational pulling by the sun and moon also causes Earth's crust to bulge in solid tides of about 20 inches (50 centimeters).

The presence of a subsurface layer of liquid water at Titan is not itself an indicator for life. Scientists think life is more likely to arise when liquid water is in contact with rock, and these measurements cannot tell whether the ocean bottom is made up of rock or ice. The results have a bigger implication for the mystery of methane replenishment on Titan.

"The presence of a liquid water layer in Titan is important because we want to understand how methane is stored in Titan's interior and how it may outgas to the surface," said Jonathan Lunine, a Cassini team member at Cornell University, Ithaca, N.Y. "This is important because everything that is unique about Titan derives from the presence of abundant methane, yet the methane in the atmosphere is unstable and will be destroyed on geologically short timescales."

A liquid water ocean, "salted" with ammonia, could produce buoyant ammonia-water liquids that bubble up through the crust and liberate methane from the ice. Such an ocean could serve also as a deep reservoir for storing methane.

НАСА публикует свежие фото Тефии

28 июня американский космический аппарат «Кассини» прошёл мимо Тефии — луны Сатурна диаметром 1 062 км, которая почти полностью состоит изо льда.

Тефия покрыта кратерами самых разных размеров, и крупнейший из них — Одиссей, который простирается в северном полушарии на 450 км, то есть охватывает почти две пятых поверхности спутника!



Это странно, ведь такой удар должен был разрушить Тефию, однако вот она на фотографиях «Кассини» — целёхонька. Возможно, дело в том, что в те времена, когда образовался Одиссей, Тефия была частично расплавленной, а потому смогла поглотить часть энергии воздействия. Остался только «шрам» — как вечное напоминание. Как видим, центральный пик кратера рухнул, оставив впадину: ещё один признак того, что спутник был не совсем твёрдым в момент столкновения.

Спутник обращается вокруг Сатурна на расстоянии 294 660 км. Из-за такой близости Тефия подвергается особенно сильному воздействию приливных сил, что, вероятно, заставило её остывать дольше более отдалённых лун. Поэтому на поверхности Тефии меньше кратеров, чем, скажем, на Рее или Дионе.

Всё, что вы здесь видите, — необработанные изображения, показывающие Тефию с расстояния 68 521 км.
