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.

A trio of pretty Cassini pics

Emily Lakdawalla • March 19, 2010

It's been a little while since I posted any Cassini pictures just because they were pretty, so here's a few recent ones, produced by amateurs from the images available on the Cassini raw images website.

Titan: Callisto with weather

Emily Lakdawalla • March 16, 2010

It's the second time I've posted with this provocative title. This time, it's in response to a new paper published last week in Science.

Hooray! Cassini's tour has been extended for SEVEN MORE YEARS!

Emily Lakdawalla and John Spencer • February 03, 2010

NASA has just announced that once Cassini's Equinox Mission runs out in June of this year, they will extend it a further seven more years, long enough for the spacecraft to see Saturn through its solstice!!

Planetary Society Advent Calendar for December 26: Titan

Emily Lakdawalla • December 26, 2009

Titan is a weird alternate-universe Earth, surprisingly similar to our own planet in some ways, but not at all like our planet in others.

Cassini VIMS sees the long-awaited glint off a Titan lake

Emily Lakdawalla • December 17, 2009

The Cassini mission announced today the first observation of a specular reflection off of a lake on Titan. A specular reflection is a mirror-like flash, and you only get one when you have a mirror-like surface -- very, very smooth.

Fun Friday photo: Titan and Rhea

Emily Lakdawalla • October 30, 2009

Cassini recently captured a series of images documenting Rhea passing behind Titan.

What "phase angle" means

Emily Lakdawalla • October 27, 2009

As is probably obvious by now, I love playing with spacecraft image data. I am always looking for excuses to dive into space image archives to unearth images of stuff in space that haven't really been seen by very many people before.

Fun for Sunday: Titan and Tethys pas de deux

Emily Lakdawalla • October 18, 2009

Checking in on Cassini's raw images this weekend, there are several nice shots to play with, including the many frames from which I tossed together this cute animation.

Changes in Titan's southern lakes

Emily Lakdawalla • October 06, 2009

Today's science press release out of the Division of Planetary Sciences meeting concerns changes in lakes near Titan's south pole observed during Cassini's mission. In brief, repeat Cassini RADAR observations of the same spots during different Titan flybys turned up places where there appeared to be dark lakes in earlier images and dry lakes in later images.

Cassini RADAR continues to gaze at Titan

Jani Radebaugh • July 27, 2009

The Cassini spacecraft made its 59th flyby of Titan, Saturn's largest moon, on Friday, July 24, and in the last few hours we have received images from the RADAR instrument in SAR (Synthetic Aperture Radar) mode.

Designing the Cassini Tour

John Smith • June 07, 2009

Each Titan flyby is not a fork in the road, but rather a Los Angeles style cloverleaf in terms of the dizzying number of possible destinations. So how did our current and future plans for the path of the Cassini spacecraft come to be? That's the question Dave Seal put to me since that's my job -- I am a tour designer.

Canto II: Titan's Atmosphere and the Solar Cycle

David Seal • June 03, 2009

David Seal explains the complications for Cassini coming from Titan's atmosphere and Solar Cycle.

Connections

David Seal • June 02, 2009

David Seal muses on his time as the mission planner for Cassini, and the history behind its name, and astronomy in Rome.

DPS meeting: Sunday: Lakes on Titan

Emily Lakdawalla • October 15, 2008

This time around DPS features three separate oral sessions on Titan, indicating just how much attention that moon is getting from the scientific community right now. From the first session, on Titan's lower atmosphere, I'm just covering the two talks on Titan's lakes.

Proof for liquids on Titan

Emily Lakdawalla • July 30, 2008

A press release from the Cassini VIMS team today is titled "NASA Confirms Liquid Lake on Saturn Moon." This may be making some of you ask: but wait, haven't they already proven there's liquid lakes on Titan?
