Cassini catches four little moons in motion

Emily Lakdawalla • August 05, 2010

I've posted animations from Cassini before in which there are multiple moons moving around, but this is one of the coolest such sequences I've seen yet.

Goodies from the latest Cassini data release

Emily Lakdawalla • August 02, 2010

I've spent a pleasurable hour or so browsing over the latest release of images from Cassini to the Planetary Data System.

Watching the birth and death of moonlets in Saturn's F ring

Emily Lakdawalla • July 22, 2010

The Saturn system is always in motion, always changing. Saturn itself is a gas giant, with swirling storms, and like the other gas giants it has a host of moons flying around, perturbing each other's motions. And then there's the rings.

Cassini eyes Janus

Emily Lakdawalla • July 13, 2010

Four times a year, the Cassini mission releases three months' worth of data gathered from Saturn and its moons to NASA's Planetary Data System.

Sharpest-ever images of Daphnis

Emily Lakdawalla • July 06, 2010

As promised last week, Cassini has delivered its best photos yet of the tiny moon Daphnis, the ringmoon that is responsible for carving out the skinny Keeler gap at the outer edge of Saturn's A ring.

Two moons making waves in the rings

Emily Lakdawalla • June 18, 2010

Just a pretty picture post, a dramatic Cassini shot on the outer edge of the A ring captured earlier this month.

Dione and Telesto, close on camera but far apart in fact

Emily Lakdawalla • May 18, 2010

This image, released today by Cassini's imaging team, is pretty cool; it shows one of Saturn's larger moons together with one of its smaller ones. I probably noticed the nice photo of Dione when it appeared on the Cassini raw images page two months ago, but I know I didn't notice the little speck below and to the left of the bigger moon. That speck is a small moon, Telesto.

A feast of pretty pictures from Cassini

Emily Lakdawalla • April 12, 2010

Cassini has it almost too easy. Point at anything in the Saturn system and you're guaranteed of a shot that looks, at least, pretty.

A busy day for Cassini: Dione plus bonus Enceladus and Janus

Emily Lakdawalla • April 08, 2010

The Cassini Saturn orbiter just completed its second very close flyby of Saturn's mid-sized iceball moon Dione, and the images from that encounter have been streaming onto the Cassini raw images website this morning.

Pretty picture: Rhea, rings, and two little moons

Emily Lakdawalla • April 06, 2010

Here's a lovely picture whose components came down from Cassini a few days ago.

Helene has two faces

Emily Lakdawalla • March 11, 2010

Yes, it's yet another post on Helene! I keep on finding new stuff to post. This time it is a really cool montage assembled by Ian Regan.

Pointing at Helene

Emily Lakdawalla • March 10, 2010

I posted already some neat images from Cassini's flyby of Helene last week, and commented on how most of the images from that encounter missed Helene entirely or only caught the moon at one edge of the camera field of view. Here's an example of one of those images.

Cassini's Helene flyby

Emily Lakdawalla • March 05, 2010

I was much anticipating Cassini's encounter with Helene on Wednesday.

Calypso coolness

Emily Lakdawalla • February 14, 2010

Cassini got pretty close to Calypso yesterday, on the way in to Mimas. Calypso is one of the smaller moonlets of Saturn.

Cassini Aegaeon and Prometheus awesomeness

Emily Lakdawalla • January 28, 2010

There were many, many treats waiting on the Cassini raw images website this morning. Yesterday, Cassini traversed the G ring, taking photos all the way.

Highlights from the January 1, 2010 Cassini imaging data release

Emily Lakdawalla • January 13, 2010

The January 1, 2010 Cassini imaging data release includes everything acquired by Cassini from January 1 to March 30, 2009 in all its high-quality glory.

Planetary Society Advent Calendar for December 27: Prometheus (hot off the presses!)

Emily Lakdawalla • December 27, 2009

This one is fresh from the spacecraft! The data were captured yesterday, December 26, by Cassini during its best yet imaging encounter with the small ringmoon Prometheus, and showed up on the Cassini raw images website today.

Awesome Cassini mutual event movies

Emily Lakdawalla • December 23, 2009

I love posting animations of Cassini images that I compose from frames grabbed from the mission's raw images website, but they are shoddy compared to the versions that eventually come out from the mission's imaging team.

Awesome Mars Express view of Phobos and Deimos together

Emily Lakdawalla • December 11, 2009

My inbox was exploding this morning with messages about a tremendously cool animation released this morning by ESA's Mars Express team. It shows Phobos crossing Deimos, in what's known as a "mutual event."

Planetary Society Advent Calendar for December 9: Atlas

Emily Lakdawalla • December 09, 2009

Here's another weird-looking one, though it's less weird from this particular, polar point of view than it is when viewed from the side.
