Door 6 in the 2010 advent calendar

Emily Lakdawalla • December 06, 2010

Time to open the sixth door in the advent calendar. Where in the solar system are these snowy slopes?

Door 1 in the Planetary Society Blog 2010 advent calendar

Emily Lakdawalla • December 01, 2010

December really has arrived, and that means that the year is racing to a close. Continuing last year's tradition, I'm counting the days to the New Year with an advent calendar, where each "door" opens onto a global image of a different world in the solar system.

Pretty picture: Three moons of Saturn

Emily Lakdawalla • October 29, 2010

The Cassini Raw Images Website always offers rewards to the browser. This evening I found the raw images necessary to create this color composite, showing the hazy orange moon Titan, the mid-sized icy moon Dione, and the tiny rock Prometheus all at the same time.

An update to the Cassini Tour Page

Emily Lakdawalla • October 27, 2010

Where's the Cassini Saturn orbiter going to be in the next week -- or hundred weeks? It's all already planned out.

Pretty picture: Europa and Jupiter

Emily Lakdawalla • September 21, 2010

Photos like this always make me think about how unimportant size is in determining whether one of the worlds of the solar system is an exciting place.

Browse the Cassini RPWS data set

Emily Lakdawalla • September 13, 2010

Periodically, usually after I've posted some images pulled out of an image archive, a reader asks me: "What about all the non-image data? Are those public too?" The answer is yes.

Pretty picture: Crescent Dione

Emily Lakdawalla • September 10, 2010

I was busy with other projects today, so today's post just asks you to look at this gorgeous three-image mosaic of a crescent Dione, taken during Cassini's most recent flyby a week ago.

Fly over Saturn's icy moons

Emily Lakdawalla • September 02, 2010

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.

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.

Two moons making waves in the rings

Emily Lakdawalla • June 18, 2010

Just a pretty picture post, a dramatic Cassini shot on the outer edge of the A ring captured earlier this month.

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.

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.

A Martian Moment in Time, revisited

Emily Lakdawalla • May 12, 2010

A good start to my day today: The New York Times' Lens Blog featured the "Martian Moment in Time" photo that Opportunity took last week in a really nice writeup. I'm so grateful, and still a little surprised, that the folks on the Mars Exploration Rover mission took this idea and ran with it!
