Decoding a Titan crater

Emily Martin • August 16, 2010

In response to Emily's entry about finally getting her hands on a subscription to the planetary science journal Icarus, I thought I would report on an article from the most recent issue: Geology of the Selk crater region on Titan from Cassini VIMS observations, by Jason Soderblom and 11 other scientists.

Weekend treats from Cassini: Enceladus plumes plus bonus Tethys and Dione

Emily Lakdawalla • August 14, 2010

Over the last couple of days Cassini flew past Enceladus, Tethys and Dione, so there are lots of treats to see on the raw images website! You should go check it out for yourself, but here are a couple of real favorites.

How to Recognize Titan from Quite a Long Way Away

Emily Lakdawalla • August 09, 2010

You know, I could fill this blog almost entirely with the amazing images that Gordan Ugarkovic locates, processes into prettiness, and uploads to his Flickr account.

Cassini catches four little moons in motion

Emily Lakdawalla • August 05, 2010

I've posted animations from Cassini before in which there are multiple moons moving around, but this is one of the coolest such sequences I've seen yet.

Goodies from the latest Cassini data release

Emily Lakdawalla • August 02, 2010

I've spent a pleasurable hour or so browsing over the latest release of images from Cassini to the Planetary Data System.

Watching the birth and death of moonlets in Saturn's F ring

Emily Lakdawalla • July 22, 2010

The Saturn system is always in motion, always changing. Saturn itself is a gas giant, with swirling storms, and like the other gas giants it has a host of moons flying around, perturbing each other's motions. And then there's the rings.

Cassini eyes Janus

Emily Lakdawalla • July 13, 2010

Four times a year, the Cassini mission releases three months' worth of data gathered from Saturn and its moons to NASA's Planetary Data System.

Sharpest-ever images of Daphnis

Emily Lakdawalla • July 06, 2010

As promised last week, Cassini has delivered its best photos yet of the tiny moon Daphnis, the ringmoon that is responsible for carving out the skinny Keeler gap at the outer edge of Saturn's A ring.

Titan's rivers are square

Emily Lakdawalla • June 11, 2010

There's a new "planetary gromorphology image of the month" posted at the International Association of Geomorphologists' Planetary Geomorphology Working Group page, and it's a cool post about the shapes of the river networks on Titan.

The most amazing image of Enceladus Cassini has captured yet

Emily Lakdawalla • May 19, 2010

Every time I think Cassini has captured the coolest image of Enceladus ever, it does better.

Pictures hitting Earth from Cassini's close Enceladus flyby today

Emily Lakdawalla • May 18, 2010

Cassini flew within 436 kilometers of Enceladus' surface today. Although it's Cassini's 11th targeted flyby of Enceladus, these close buzzes are never routine.

Dione and Telesto, close on camera but far apart in fact

Emily Lakdawalla • May 18, 2010

This image, released today by Cassini's imaging team, is pretty cool; it shows one of Saturn's larger moons together with one of its smaller ones. I probably noticed the nice photo of Dione when it appeared on the Cassini raw images page two months ago, but I know I didn't notice the little speck below and to the left of the bigger moon. That speck is a small moon, Telesto.

New maps of Enceladus and other moons

Emily Lakdawalla • May 13, 2010

Every time Cassini gets reasonably close to one of the moons of Saturn, whether the close approach is a targeted one or just an opportunistic encounter, its planners usually take advantage of the proximity to take a bunch of photos.

Radar glories in Titan rivers

Emily Lakdawalla • May 11, 2010

Wow, this is a cool paper. Here's the gist: the Cassini RADAR team has spotted some river channels on Titan that shine so brightly in radar images, there must be something special going on to explain that brightness.

New names for Rhea

Emily Lakdawalla • April 27, 2010

I learned today from Jason Perry that 42 new crater names have been approved by the International Astronomical Union for Rhea, the second largest of Saturn's moons.

Titan and Dione: The same, but different

Emily Lakdawalla • April 22, 2010

Here's a new lovely color composition of Titan and Dione captured by Cassini. This one was taken on April 20, 2010; a set of 15 raw images taken of the two moons just showed up on the Cassini raw images website.

Hey, I'm on APOD today!

Emily Lakdawalla • April 20, 2010

A big thanks to Bob Nemiroff, editor of NASA's Astronomy Picture of the Day website, for picking my composition of a set of Cassini photos of Dione and Titan for today's offering.

A calming Titan

Emily Lakdawalla • April 19, 2010

Usually I like Mondays, but today I'm feeling a bit overwhelmed. When I get overwhelmed, I look at pictures from Cassini.

Dione and Titan

Emily Lakdawalla • April 12, 2010

It's axiomatic that as soon as I post about pretty Cassini pictures, another set of pretty photos will appear on the raw images website.

A feast of pretty pictures from Cassini

Emily Lakdawalla • April 12, 2010

Cassini has it almost too easy. Point at anything in the Saturn system and you're guaranteed of a shot that looks, at least, pretty.
