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.

An update on the Huygens Doppler Wind Experiment

Posted by Emily Lakdawalla on 2005/11/08 03:28 CST

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.

A change of plans for Cassini: higher altitude for the "T7" Titan flyby

Posted by Emily Lakdawalla on 2005/07/15 01:00 CDT

The June 15 Cassini Project Update includes a note about a difficult decision -- they are raising the altitude of an upcoming Titan flyby, "T7," which is scheduled for September 7.

News: Dark Spot Near the South Pole: A Candidate Lake on Titan?

Posted by Emily Lakdawalla on 2005/06/28 11:00 CDT

The Cassini imaging team has released an image containing a feature unlike any other that they have seen on Titan. The very dark color, curvaceous outline, and sharp edge of the feature have led them to the conclusion that it could well be the long-theorized but never-before-seen body of liquid hydrocarbons on the surface of Titan.

New Mosaics of Huygens' Titan Images

Posted by Emily Lakdawalla on 2005/05/05 11:00 CDT

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

News: Radio Astronomers Rescue Science Results for Huygens' Doppler Wind Experiment

Posted by Emily Lakdawalla on 2005/02/09 10:00 CST

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.

3-D Views of Titan's Surface from Huygens

Posted by Emily Lakdawalla on 2005/02/08 10:00 CST

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.

They Were the First, and the Last, to Hear from Huygens

Posted by Emily Lakdawalla on 2005/02/07 10:00 CST

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?

Huygens' Descending View of Titan

Posted by Emily Lakdawalla on 2005/01/17 10:00 CST

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.

Raw Images from Huygens

Posted by Emily Lakdawalla on 2005/01/16 10:00 CST

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.

Huygens blog: "It's impossible to resist the speculation."

Posted by Emily Lakdawalla on 2005/01/15 07:31 CST

After a mere twelve hours of work, all six of the science teams on Huygens were able to report results this morning. You could easily tell the difference between the administrators and the scientists on this morning's press panel: the administrators looked bright, fresh, and well-rested, while the scientists looked decidedly weary.
