Fly over Saturn's icy moons

Posted by Emily Lakdawalla on 2010/09/02 11:09 CDT

A couple of weeks ago Paul Schenk posted a few really cool videos to his personal blog. Paul's subspecialty is the topography of icy moons, and he's been doing a lot of work on the moons of Saturn lately.

Decoding a Titan crater

Posted by Emily Martin on 2010/08/16 01:42 CDT

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

Posted by Emily Lakdawalla on 2010/08/14 06:52 CDT

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.

Cassini catches four little moons in motion

Posted by Emily Lakdawalla on 2010/08/05 05:06 CDT

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.

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

Posted by Emily Lakdawalla on 2010/07/22 09:09 CDT

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.

Sharpest-ever images of Daphnis

Posted by Emily Lakdawalla on 2010/07/06 02:58 CDT

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

Posted by Emily Lakdawalla on 2010/06/11 01:07 CDT

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.

Pictures hitting Earth from Cassini's close Enceladus flyby today

Posted by Emily Lakdawalla on 2010/05/18 05:48 CDT

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

Posted by Emily Lakdawalla on 2010/05/18 12:28 CDT

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

Posted by Emily Lakdawalla on 2010/05/13 02:26 CDT

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

Posted by Emily Lakdawalla on 2010/05/11 04:53 CDT

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.
