Steins, a jewel in the asteroid belt

Emily Lakdawalla • June 13, 2012 • 1

A notice of some new names for features on asteroid 2867 Steins inspired me to dig up the data set from the September 5, 2008 Rosetta flyby and explore it to see what it contained.

Video: Saturn makes its own drama (with a little help)

Emily Lakdawalla • May 22, 2012 • 5

The apparently simple device of running Cassini images together like a flipbook makes for a dramatic movie, especially with the help of well-timed musical cues.

Methone, an egg in Saturn orbit?

Emily Lakdawalla • May 21, 2012 • 8

Cassini obtained its first high-resolution images of Methone on May 20, 2012. Methone is one of the smallest regular moons of Saturn, having a diameter of only about 3 kilometers. It was the first moon that Cassini discovered, very early in Cassini's mission at Saturn, in 2004.

A stunning view of Mars from Argyre to Thaumasia

Emily Lakdawalla • May 18, 2012

Image magician Daniel Machacek has done it again, producing a jaw-dropping view of Mars from Viking Orbiter 1, featuring a frosty Argyre basin and stretching across to a series of faults called Thaumasia Fossae.

In Honor of JUICE, a New View of Europa

Ted Stryk • May 07, 2012 • 2

To celebrate ESA's selection of the JUICE mission to Jupiter, Ted Stryk produced a new global view of Europa from Galileo data.

Pretty pictures from Cassini's recent Dione flyby

Emily Lakdawalla • May 04, 2012

Cassini performed its last of three close encounters with Enceladus for 2012 two days ago, and followed the flyby with some spectacular images of Dione.

3D view of an unnamed lunar crater

Grab your red-blue 3D glasses and dive in to this small but spectacular unnamed lunar crater as seen in a Lunar Reconnaissance Orbiter photo.

Ski Helene?

Emily Lakdawalla • April 20, 2012 • 2

I enthused about these Helene images the first time they came down from Cassini, and then forgot about them, and then was thrilled anew a couple of weeks ago when Daniel Macháček posted his version, processed from data published by the Cassini imaging team on April 1.

Pretty Pictures: Amazing Asteroid Lutetia

Emily Lakdawalla • April 10, 2012

A long-awaited data set is finally public (well, long-awaited by me, at least). The Rosetta team has now published their data from the July 10, 2010 flyby of asteroid (21) Lutetia. This data set is absolutely stunning, and my friends in the amateur image processing community wasted no time in creating art out of it.

Pretty picture: Janus and Saturn

Emily Lakdawalla • April 04, 2012

In the last few days as it's rounded periapsis in its current orbit of Saturn, Cassini has taken a lot of great photos of Saturn's moons. One series of photos was taken from pretty close to Janus, a moon about a third the diameter of Enceladus that orbits between the F and G rings. And among those, several were taken with the moon sitting in front of Saturn.
