First-ever high-resolution Synthetic Aperture Radar image of Enceladus

Posted by Emily Lakdawalla on 2011/12/01 07:22 CST

On the November 6, 2011 flyby of Enceladus -- the third such flyby in just a few weeks -- the Cassini mission elected to take a SAR swath instead of using the optical instruments for once. So here it is: the first-ever SAR swath on Enceladus. In fact, the only other places we've ever done SAR imaging are Earth, the Moon, Venus, Iapetus, and Titan.

Pretty pictures: Dancing moons

Posted by Emily Lakdawalla on 2011/09/28 12:28 CDT

Since Cassini currently orbits Saturn within the plane of Saturn's rings, it has lots of chances to catch two or more moons in the same photo. One such "mutual event" happened on September 17, featuring four moons: Titan, Dione, Pan, and Pandora.

The Making of Martian Clouds in Motion: Part 1, working with Mars Express HRSC data

Posted by Emily Lakdawalla on 2011/08/22 08:39 CDT

Last Friday I posted an awesome video of Martian clouds in motion. This week I'll tell you how I made it. The how-to is split up into two parts. The first, today, is how to access Mars Express HRSC image data and process it into the individual animation frames, from which you can make an animated GIF.

Comet Garradd in 3D (sort of)

Posted by Emily Lakdawalla on 2011/08/12 12:52 CDT

Amateur astronomer Patrick Wiggins sent me this neat little animation of comet Garradd moving against background stars through an hour's worth of observing. I'm not any kind of astronomer but if I were I think I would get a kick out of looking at things that appear to move within one night of watching -- asteroids, comets, Jupiter's spots. I'm impatient that way.

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.
