Planetary Society Advent Calendar for December 26: Titan

Posted by Emily Lakdawalla on 2009/12/26 11:28 CST

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

Posted by Emily Lakdawalla on 2009/12/17 04:28 CST

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

Posted by Emily Lakdawalla on 2009/10/30 01:19 CDT

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

What "phase angle" means

Posted by Emily Lakdawalla on 2009/10/27 01:42 CDT

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

Posted by Emily Lakdawalla on 2009/10/18 05:08 CDT

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

Posted by Emily Lakdawalla on 2009/10/06 05:19 CDT

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

Posted by Jani Radebaugh on 2009/07/27 07:08 CDT

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

Posted by John Smith on 2009/06/07 12:01 CDT

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.

DPS meeting: Sunday: Lakes on Titan

Posted by Emily Lakdawalla on 2008/10/15 03:52 CDT

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

Posted by Emily Lakdawalla on 2008/07/30 07:02 CDT

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?

Saturn, Tethys, and Titan

Posted by Emily Lakdawalla on 2008/03/25 12:37 CDT

I thought that today's image release from the Cassini imaging team was exceptionally pretty.

LPSC: Thursday: Rovers, Titan, Mars, Venus Express, Neptune

Posted by Ted Stryk on 2008/03/14 03:49 CDT

I spent a large portion of the day at the Lunar and Planetary Institute's library and presented my own poster during the poster sessions, so my coverage of Thursday's sessions is limited.

Showing off Saturn's moons

Posted by Emily Lakdawalla on 2008/02/19 04:40 CST

There was a press release from the Cassini mission today about a pile of papers (14 of them!) being published in the journal Icarus about Saturn's icy moons. I haven't had time to read more than the overview article yet, but I wanted to come up with a graphic for an overview of Saturn's moons, and I couldn't resist delving into the massive database of Cassini images to produce something new

Titan's south pole looks pretty dry

Posted by Emily Lakdawalla on 2008/01/11 04:31 CST

One of the major results from the Cassini mission last year was the production of a mosaic of images from its RADAR instrument covering Titan's north pole. Titan's north pole has lakes upon lakes, some big, some small, but everywhere you look, there they are.

News flash: Lakes at Titan's south pole, too, on top of the land of lakes in the north

Posted by Emily Lakdawalla on 2007/10/11 12:32 CDT

Lakes have been spotted near the south pole of Titan before, in this image by the ISS team, which was considered compelling but not conclusive at the time.

Europlanet: RADAR views of Titanian Geology

Posted by Doug Ellison on 2007/08/24 05:38 CDT

"What plays in Potsdam stays in Potsdam" - that's how Ralph described a problem I mentioned over at UMSF where I explained I couldn't combine the audio of my talk with the MOV of the slides because you're not allowed to record presentations. It's "law of the stag" for conferences. So, in the spirit of the law, here's an overview of Ralph's excellent overview of Titanian geology as seen by various RADAR passes.

OPAG, Day 1: Hot-air ballooning on Titan

Posted by Emily Lakdawalla on 2006/05/06 10:46 CDT

The next presentation at OPAG was given by Ralph Lorenz and Tom Spilker on a Titan Montgolfiere Mission Study. What's a Montgolfiere, you ask?

Too much outer planets news for me to read (much less report on)

Posted by Emily Lakdawalla on 2006/05/04 08:51 CDT

Before I get to my notes from OPAG I want to minimally acknowledge today's news, which I'll have to get to in more detail later.
