Lots of great stuff in the latest Cassini data release

Emily Lakdawalla • April 13, 2011

I've got some lovely pictures from Saturn to show you! Every three months, the Cassini mission dumps gigabytes worth of precious Saturn data into the Planetary Data System, and the latest gift came on April 1. This particular pile of data, which was taken between April 1 and June 30, 2010, contains a lot of really terrific moon observations.

Emily Lakdawalla • April 07, 2011

Regular readers of this blog will find the content of today's 365 Days of Astronomy Podcast familiar, because it's an update on what the solar system exploration spacecraft are up to, based on my monthly "what's up" updates.

Mercury: a moon-scale body

Emily Lakdawalla • March 17, 2011

As I wait for the MESSENGER Mercury Orbit Insertion webcast to start, I thought I'd fiddle with some images to point out that Mercury is a bridge between the scales of planets and the scales of moons.

Emily Lakdawalla • March 11, 2011

This is both a Lunar and Planetary Science Conference (LPSC) update and a public service announcement. Ted Stryk has been working for years to locate the original Pioneer 10 and 11 image data from the Jupiter and Saturn encounters.

Bye bye, Kodachrome, but "Kodak moments" will live on in space

Emily Lakdawalla • December 31, 2010

This week is the end for Kodachrome film. It's a casualty of the digital revolution.

Time to open the twentieth door in the advent calendar. Where in the solar system is this diffuse blob and stripy sea?

365 Days of Astronomy Podcast: What's in a Science Meeting?

Emily Lakdawalla • November 17, 2010

Today the 365 Days of Astronomy podcast aired my contribution, What's in a Science Meeting?, about what scientists do at big meetings like the Division of Planetary Sciences.

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.

Voyager Mission Status Bulletins: Jupiter and Saturn

Emily Lakdawalla • September 24, 2010

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.

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.

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.

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.

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.
