What I see in the first high-res Dawn images of Vesta

Posted by Emily Lakdawalla on 2011/08/02 11:22 CDT

I had to wait until the kids were in bed and the husband fed last night before I finally had time to sit down and really look at the Dawn images of Vesta. And I still hardly knew where to begin. This brand new world is just so different than others I've seen.

Pretty movie: Everything in the Saturn system is in motion!

Posted by Emily Lakdawalla on 2011/07/26 06:28 CDT

A few weeks ago a producer for a public television space documentary asked me if I knew of any cool Cassini animations and my answer was, "Ooh, what a great excuse to have some fun digging around in the Cassini data archives." Here is the most fun animation I came up with in response to the request.

Cassini animations: Rhea and Dione and Titan

Posted by Emily Lakdawalla on 2011/06/28 04:12 CDT

I've been mucking about in the Cassini data archives (as I often do when procrastinating) and unearthed a neat, if short, mutual event sequence of two crescent moons passing by each other.

Amateur takes on the Dawn Vesta images

Posted by Emily Lakdawalla on 2011/06/24 10:12 CDT

I am pretty sure that the Dawn team put nearly every image they've taken of Vesta so far in the animation they released yesterday, which is awesome. It hasn't taken long for the amateur image processing community to pick that animation apart into its component frames and process the heck out of the individual images to produce some very fine looking images and animations.

Cassini finally catches Helene

Posted by Emily Lakdawalla on 2011/06/20 04:41 CDT

Cassini has finally achieved gorgeous global imaging of Helene with a spectacular flyby on Saturday, in which they got Helene to pose prettily for the camera from beginning to end of the encounter. And what a wacky, wacky world Cassini has revealed Helene to be!!

Nearly behind Saturn

Posted by Emily Lakdawalla on 2011/04/19 01:03 CDT

Some recent photos that Cassini took from a position nearly in Saturn's shadow caught my eye, and I made a quick color composite. What an amazing view this would be if you were riding on the spacecraft!

Lots of great stuff in the latest Cassini data release

Posted by Emily Lakdawalla on 2011/04/13 04:56 CDT

I've got some lovely pictures from Saturn to show you! Every three months, the Cassini mission dumps gigabytes worth of precious Saturn data into the Planetary Data System, and the latest gift came on April 1. This particular pile of data, which was taken between April 1 and June 30, 2010, contains a lot of really terrific moon observations.

Having some fun with Curiosity's pretty face (plus, a conversation about Curiosity with a 4-year-old)

Posted by Emily Lakdawalla on 2011/04/08 12:03 CDT

The photo I took of Curiosity's "face" and posted on Monday seems to have tickled a lot of people. I understand it's the subject of a "Photoshop this Mars rover" challenge at Fark, and a couple of the guys over at unmannedspaceflight.com have been having a field day with it.

Posted by Emily Lakdawalla on 2011/03/11 01:39 CST

This is both a Lunar and Planetary Science Conference (LPSC) update and a public service announcement. Ted Stryk has been working for years to locate the original Pioneer 10 and 11 image data from the Jupiter and Saturn encounters.

Pretty picture: Viking 1 across Mars

Posted by Emily Lakdawalla on 2011/03/09 10:10 CST

Image magician Daniel Macháček has been turning his energies to Viking Orbiter views of Mars lately, with some stunning results, like the one below. I'm not sure how he makes images that look so sharp and clean and with such rich color out of the Viking Orbiter data.

Pretty picture: Saturn storm

Posted by Emily Lakdawalla on 2011/03/08 10:46 CST

To relieve this week's text-heavy LPSC posts, here's a brief one on an incredible panorama across Saturn's northern storm, taken on February 26 by Cassini and assembled by unmannedspaceflight.com member "Astro0."

Some recent pictures of Saturn's northern storm

Posted by Emily Lakdawalla on 2011/02/07 04:35 CST

There is a huge storm that's spreading across so much of Saturn that it's been readily visible even from Earth-based telescopes. Over the past couple of days a couple of new images of Saturn have appeared that show just how enormous the storm is today.

Posted by Emily Lakdawalla on 2011/01/31 03:14 CST

Here's an image I've been meaning to post for months, a new mosaic from Voyager 1 by Ted Stryk of Io crossing Jupiter's terminator as it neared closest approach.

Uranus and Challenger

Posted by Emily Lakdawalla on 2011/01/28 09:21 CST

In the past week there have been 25th anniversaries of two events in 1986, one great, one terrible: the closest approach of Voyager 2 to Uranus on January 24, and the explosion of the space shuttle Challenger upon liftoff on January 28.

Butterfly crater on Mars

Posted by Emily Lakdawalla on 2011/01/27 05:32 CST

I've spent the day noodling around in the current issue of Icarus, following up some of the more interesting stories within its table of contents, and came across a picture of this very cool crater -- actually, set of craters -- on Mars.

Animation of Phobos rotating from recent Mars Express flyby images

Posted by Emily Lakdawalla on 2011/01/25 10:18 CST

Daniel Macháček has colorized some terrific images of Phobos and run them through some morphing software to make a seamless animation that appears to show Phobos rotating before you.

Two fine color Cassini animations: Prometheus rotating, Tethys and Dione dancing

Posted by Emily Lakdawalla on 2011/01/20 11:23 CST

Daniel Macháček has reached into the dark side of Prometheus and pulled out an incredible amount of detail where the potato-shaped moon is illuminated by Saturnshine. He produced an animation that morphs among the three sets of four-filter color images that Cassini snapped during the flyby.
