Jani Radebaugh, Titan Explorer

Bill Dunford • July 23, 2013

Robotic space exploration is human exploration. Meet one of the people behind the machines.

Dunes on Tatooine

Ralph Lorenz • July 17, 2013

The fictional world Tatooine, scene of action in the Star Wars movies, is named after a town in Tunisia, where parts of the movies were filmed. The desert backdrops against which the movies were filmed are real terrestrial landscapes, which prove to be perhaps unexpectedly dynamic.

New names for Pluto's little moons Kerberos and Styx; and a new moon for Neptune

Emily Lakdawalla • July 15, 2013

Pluto's moons, formerly known as "P4" and "P5," are now named Kerberos and Styx; I thought I'd help place them into context with a little help from Cassini. Also, Neptune now has a 14th known moon.

Scale comparisons of the solar system's major moons

Emily Lakdawalla • July 10, 2013

A few presentation slides with pretty pictures, sized to scale, of the large moons of the solar system.

The Space Computer and the Beautiful Worlds

Bill Dunford • June 30, 2013

An "Up Goer 5" tribute to the Cassini mission.

Mimas and Pandora dance

Emily Lakdawalla • May 15, 2013

I've been out of town for a couple of days and am overwhelmed with work and an overflowing email box. So what do I do about that? I ignore what I'm supposed to be doing and play with Cassini raw image data, of course. Here is a "mutual event" of Mimas (the bigger moon) and Pandora (the outer shepherd of the F ring).

Doing a science on Titan

Sarah Hörst • May 15, 2013

A tale from the scientific trenches: laboratory work to simulate Titan's rich atmosphere.

Planetary Society Weekly Hangout: Reports from the Lunar and Planetary Science Conference

Emily Lakdawalla • March 28, 2013

On Thursday at noon PDT / 1900 UTC I'll report on some of my favorite findings from LPSC, and answer your questions about the latest planetary science.

LPSC 2013: License to Chill (or, the solar system's icy moons)

Emily Lakdawalla • March 27, 2013

Reports from the March 19 session at the Lunar and Planetary Science Conference covering eight icy moons in the outer solar system: Ganymede, Europa, Dione, Rhea, Mimas, Tethys, Enceladus, and Miranda.

Enceladus: A problem of contrast

Emily Lakdawalla • January 30, 2013

Time for my quarterly foray into the Cassini archival science data! The very first image I downloaded from the January 1, 2013 data release presented an interesting challenge to my image processing skill. I'll show you the pretty picture of Enceladus and then explain how I processed it.

Planetary Society Weekly Hangout, Thu Dec 20 1200PT/2000UT: Making Titan in the laboratory with Sarah Hörst

Emily Lakdawalla • December 19, 2012

Join us for our weekly Google+ Hangout Thursday at noon PT / 2000 UT. This week, I'm excited to have as a guest Sarah Hörst. Sarah is a postdoc at the University of Colorado whose current line of research involves experimental work on the complex atmospheric chemistry of Titan. She is also applying to be an astronaut!

Watching the slow shift of seasons on Titan

Emily Lakdawalla • November 06, 2012

A sharp-eyed amateur noticed two images of Titan taken 20 months apart from nearly exactly the same perspective, and they illustrate how the shifting of Saturn's seasons has brought change to Titan's atmosphere.

A huge color global view of Dione

Emily Lakdawalla • October 23, 2012

From the Cassini data archives comes a huge (5000 pixels square!) color image of Saturn's icy moon Dione, worth investigating from both near and far.

DPS 2012, Day 5: How to make asteroids crunchy on the outside and soft in the middle

Emily Lakdawalla • October 19, 2012

A summary of just one talk from the Division for Planetary Sciences meeting, by Lindy Elkins-Tanton, which provided a neat explanation for how asteroids can be melted and layered on the inside yet have a primitive-looking exterior.

DPS 2012, Tuesday: Titan's surface

Emily Lakdawalla • October 17, 2012

Tuesday morning at the Division of Planetary Sciences meeting featured talks on the surface composition and landforms on Titan, including lakes and "hot cross buns."

DPS 2012, Monday: Icy moons and a four-star exoplanet

Emily Lakdawalla • October 15, 2012

In the first full day of the annual meeting of the Division of Planetary Sciences of the American Astronomical Society, I listened to scientific sessions on icy worlds and on an exoplanet in a four-star system.

Happy Cassini PDS Release Day!

Emily Lakdawalla • October 08, 2012

It's a quarterly feast day for me: the day that the Cassini mission delivers three months' worth of data to NASA's Planetary Data System. Here's a few images processed from the October 1, 2012 data release.

Sturzstroms on Saturn's Moon Iapetus

Kelsi Singer • October 01, 2012

Long-runout landslides (sturzstroms) are found across the Solar System. They have been observed primarily on Earth and Mars, but also on Venus, and Jupiter’s moons Io and Callisto. I have just published a paper about sturzstroms on Iapetus.

A couple of gems from the archives

Emily Lakdawalla • September 10, 2012

We're still working on migrating content from the old to the new website. This week, that means I am looking, one by one, through some great amateur-processed space images.

Pretty picture: Meet Tethys

Emily Lakdawalla • June 20, 2012

Just a pretty global view of one of Saturn's flock of icy moons, newly processed from archival data by Gordan Ugarkovic.
