Long before the Cassini-Hugygens spacecraft launched in 1997 to explore Saturn and Titan, The Planetary Society urged NASA to make the mission a reality.

Huygens may have landed on Titan over a decade ago, but a group of researchers from York University were able to make a new and unexpected discovery with this older dataset.

The landing of Huygens on Titan was a significant moment for planetary science and a great accomplishment for Europe. But the Huygens landing also stimulated the development of the international community of amateur image processors that does such great work with space images today. I was in the midst of it all at the European Space Operations Centre in Darmstadt.

Since Seth MacFarlane tweeted that this weekend's episode of Cosmos was going to include a segment on lakes on Titan, I thought I'd write a post explaining the basics of Titan lakes.

A lively discussion and debate between planetary polymaths Ralph Lorenz and Jeffrey Moore about Titan, hosted by the Denver Museum of Nature and Science, moderated by David Grinspoon.

It's a fact of life in science that not all of your hypotheses will turn out to be correct (or even verifiable at all). But there's a bias toward the publication of positive results -- the discovery of this, or the proof of that.

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.

Today, I'm kicking the week off with a look at the unusually intense confluence of far flung planetary exploration that's just around the corner, starting the middle of next year.

I am working my way steadily through the seven Huygens papers that were released by Nature magazine Wednesday on their

While I was at the Division of Planetary Sciences meeting in Cambridge in September I had a chance to chat with David Atkinson, who's a member of the Doppler Wind Experiment team on Huygens. They and the other instrument teams have been plugging away at analyzing their data.

I've just posted a very brief update on the upcoming Titan flyby, which will be the first to include RADAR imaging across the Huygens landing site.

In the midst of all this hoopla about Deep Impact, I haven't been able to give the proper attention to Cassini, which began its second year of operations at Saturn today.

Although the two spacecraft traveled a billion kilometers together to study Titan, Cassini and Huygens are two very different types of missions.

Scientists have released a new sound from Huygens, representing the radio signal that Cassini detected from the little probe as it descended to Titan's surface.

Earth's radio astronomers have saved the day for one of the Huygens instrument teams. Today, the Doppler Wind Experiment (DWE) team announced their first science results, despite losing nearly all of their expected data.

It's been close to a month since Huygens descended to the surface of Titan. Many visitors to this website have expressed impatience with the pace of the release of images from the Huygens cameras, a feeling that is no doubt shared by space enthusiasts around the world who are eager to see refined views of the alien surface of Titan.

On January 14, 2005, the eyes of the world were on the European Space Operations Centre in Darmstadt, Germany, where Huygens mission operators were anxiously awaiting news from Huygens. Would the little probe -- a mission built in seventeen countries, more than twenty years in the making -- be a success, or would it prove a repeat of the heartbreaking silence of Beagle 2?

Scientists from the Huygens Descent Imager Spectral Radiometer (DISR) team have released their first mosaic of images captured during Huygens' descent. The mosaic is composed of 30 images captured by the Medium Resolution Imager of Huygens' Descent Imager Spectral Radiometer while the probe was spinning and descending toward Titan.

In the 48 hours since Huygens' data first began streaming back to Earth, a few processed images of the channeled landscape and bouldery landing site have been released to the public. Now, the Descent Imager Spectral Radiometer team at the University of Arizona has put all of Huygens' images online for the public to view.
