John Spencer: Cassini's proposed extended-extended mission tour

Posted by John Spencer on 2009/02/24 02:58 CST

It seems like no time since we selected Cassini's extended mission tour of the Saturn system, in early 2007. Now we're flying that tour, which extends Cassini's original four years in Saturn orbit for another 27 months, until September 2010. So now we're looking into the future- far into the future.

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?

One of my favorite amateur image magicians, Gordan Ugarkovic continues to play around with the amazing data recently released by the Cassini mission, covering the Iapetus encounter of last September. Here's a lovely mosaic he just put together of the Voyager Mountains.

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.

The Orbital Dance of Epimetheus and Janus

Posted by Emily Lakdawalla on 2006/02/07 11:00 CST

Saturn is surrounded by a crowded family of rings and moons, and two of those moons -- Epimetheus and Janus -- orbit Saturn so close together that it seems as though their different orbital speeds should make them crash into each other.

A way-cool Cassini picture: rings, Titan, Dione, Prometheus

Posted by Emily Lakdawalla on 2005/10/19 07:12 CDT

I just noticed this picture on the Cassini raw images website. I love these "many worlds" pictures.

A little more Hyperion

Posted by Emily Lakdawalla on 2005/08/18 08:35 CDT

Checking the Cassini raw images website, I found quite a few more images of Hyperion this morning. It looks like Cassini had a leisurely flyby of the little moon from roughly 700,000 kilometers' distance.

A couple cool raw Cassini pics -- and a break in the data

Posted by Emily Lakdawalla on 2005/07/19 04:56 CDT

I monitor the Cassini website to keep my eye out for cool pictures, and it's usually relatively easy to figure out what the spacecraft is looking at (rings, moon, Saturn, whatever). Sometimes, though, the images can be very confusing.
