An update on the Huygens Doppler Wind Experiment

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.

Dione encounter today

Cassini is already on its way in to a close, 500-kilometer encounter with Dione -- it's less than four hours away now, at 17:52 UTC.

Hyperion in color

Here is a gorgeous color mosaic of Hyperion assembled by amateur image processor Mattias Malmer from images from the recent flyby.

Amazing views of Hyperion

I've finally worked my way through all of the Hyperion images that were returned from the last flyby. It's a wonderful data set.

Some bad news for fans of Titan RADAR

According to Jason Perry, the much-anticipated Titan-7 RADAR imagery across Titan's southern hemisphere may have been lost due to an error on Cassini's solid state recorder. That will be very sad if it turns out to be true.

A little more Hyperion

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.

Cassini tour page revised

Cassini mission planner Dave Seal just gave me the latest reference trajectory for Cassini, so I've gone through and updated the flyby altitudes on the Cassini tour page.

Enceladus is alive!

It's official: Enceladus has joined the rarefied community of Solar System objects that have been caught in the act of making new geology.

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

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.
