We're at the Cape! More properly, we're at Cocoa Beach just down the coast, having flown in from Denver today.

I'm at home on a Sunday morning, five days before leaving for the Cape (assuming the current launch schedule, with the first launch opportunity on January 17th, continues to hold).

I've been sifting through the data I obtained last week on the lightcurve of binary Kuiper Belt object 1998 SM165 during my three nights on the Lowell Observatory 72

It's been a while since I posted some Cassini pictures here just because they were pretty.

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.

The images from Cassini's Dione encounter yesterday have started coming back, and there is a really cool set of 16 pictures of Dione and Rhea.

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.

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

Yesterday, this quarter's release of Cassini data showed up at the Planetary Data System (PDS). The PDS is the public repository for all of NASA's data.

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.

I got an email last night from Anne Verbiscer, whom I had contacted about rounding up some amateur astronomers to help the Cassini mission with some photometric observations of Hyperion.

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.
