Pretty picture: newly processed high-res view of a fractured icy moon, Dione

Emily Lakdawalla • December 04, 2013

Here's a lovely new view of Dione, one of the lovely mid-sized icy moons of Saturn, assembled by Daniel Macháček.

Just what is going on in that magnificent Cassini image of Saturn?

Emily Lakdawalla • November 13, 2013

It took months of work (and no wonder) but the wait was worth it: here is Cassini's spectacular view of Saturn, captured on July 19, 2013, as Cassini passed through Saturn's shadow. If you're a little confused by the image, I'm here to help: I've posted a video explainer.

Will We Lose Cassini’s "New" Mission at Saturn to Budget Cuts?

Van Kane • November 12, 2013

NASA’s shrinking budgets for planetary exploration may force it to decide between continued funding for the Saturn Cassini mission and the continued funding for its Mars missions.

One for the history books: Stunning Saturn mosaic captured last week by Cassini

Emily Lakdawalla • October 16, 2013

I try to be measured in my praise for spacecraft images. Not every photo can be the greatest space image ever. But this enormous mosaic showing the flattened globe of Saturn floating within the complete disk of its rings must surely be counted among the great images of the Cassini mission.

America's Pastime: Planetary Science

Apologies to baseball fans and others for the theme of this week's Planetary Radio preview, which has star player Emily Lakdawalla on deck.

DPS 2013: Tidbits from Titan

Emily Lakdawalla • October 09, 2013

I attended a few talks at the Division for Planetary Sciences meeting today that concerned Titan's origin and interesting surface, and then one in the afternoon about the atmosphere.

Probing Titan's Atmosphere

Sarah Hörst • August 26, 2013

By now I hope that everyone has seen some of the spectacular images of the Saturn system (and especially Titan!) from the Cassini-Huygens mission. However, the measurements that often make my heart race are taken by instruments that reveal Titan in ways that our eyes cannot see.

Pretty picture: spectacular Saturn and Titan

Emily Lakdawalla • August 15, 2013

A lovely view of the ringed planet and its hazy moon seen from nearly behind them just a few days ago.

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

Pretty picture: Looking backward

Emily Lakdawalla • July 23, 2013

Here it is: the view from Saturn of our Earthly home, one and a half billion kilometers away. We see Earth and the Moon through a thin veil of faintly blue ice crystals, the outskirts of Saturn's E ring. Earth is just a bright dot -- a bit brighter than the other stars in the image, but no brighter than any planet (like Saturn!) in our own sky.

Return of the Pale Blue Dot

You can be part of a planetwide group photo as Cassini and MESSENGER turn their cameras Earthward on July 19.

The Shores of the Kraken Sea: Great Place Names in the Solar System

Bill Dunford • May 28, 2013

Nothing reflects the romance of deep space exploration more than the evocative names of places on the planets and moons.

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).

One of my favorite image processing tricks: colorizing images

Emily Lakdawalla • April 23, 2013

An easy image processing trick -- using lower-resolution color data to colorize a black-and-white photo -- is relied upon by many space missions to keep data volumes low. Here's how to do it.

In a New Light

Cassini's unique views of Jupiter and Saturn.

First Analysis: the NASA Planetary Science Budget for 2014

Van Kane • April 10, 2013

No mission to Europa, diminished funding for outer planets missions, a small bump to small spacecraft missions, and an increase for asteroid detection are part of the White House's proposal for NASA in 2014.
