Pretty picture: Three moons of Saturn

Posted by Emily Lakdawalla on 2010/10/29 12:08 CDT

The Cassini Raw Images Website always offers rewards to the browser. This evening I found the raw images necessary to create this color composite, showing the hazy orange moon Titan, the mid-sized icy moon Dione, and the tiny rock Prometheus all at the same time.

An update to the Cassini Tour Page

Posted by Emily Lakdawalla on 2010/10/27 11:24 CDT

Where's the Cassini Saturn orbiter going to be in the next week -- or hundred weeks? It's all already planned out.

DPS 2010: Pluto and Charon opposition surges, Nix and Hydra masses, Pluto and Eris compositions

Posted by Emily Lakdawalla on 2010/10/25 11:18 CDT

An awful lot of the talks in the Pluto session on Tuesday morning, October 5, at the Division of Planetary Sciences meeting spent more time focusing on how bad weather conditions were during the astronomers' attempts to view Pluto as it occulted background stars than they did on any measurements or science that came out from the data.

Voyager Mission Status Bulletins: Jupiter and Saturn

Posted by Emily Lakdawalla on 2010/09/24 01:27 CDT

Last week I posted a stack of Voyager Mission Status Bulletins, which were once the main resource for space enthusiasts to follow the dramatic events and photos of an in-flight space mission.

How to Recognize Titan from Quite a Long Way Away

Posted by Emily Lakdawalla on 2010/08/09 05:16 CDT

You know, I could fill this blog almost entirely with the amazing images that Gordan Ugarkovic locates, processes into prettiness, and uploads to his Flickr account.

Cassini catches four little moons in motion

Posted by Emily Lakdawalla on 2010/08/05 05:06 CDT

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.

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

Posted by Emily Lakdawalla on 2010/07/22 09:09 CDT

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.

Sharpest-ever images of Daphnis

Posted by Emily Lakdawalla on 2010/07/06 02:58 CDT

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.

A Martian Moment in Time, revisited

Posted by Emily Lakdawalla on 2010/05/12 02:30 CDT

A good start to my day today: The New York Times' Lens Blog featured the "Martian Moment in Time" photo that Opportunity took last week in a really nice writeup. I'm so grateful, and still a little surprised, that the folks on the Mars Exploration Rover mission took this idea and ran with it!

Designing the Cassini Tour

Posted by John Smith on 2009/06/07 12:01 CDT

Each Titan flyby is not a fork in the road, but rather a Los Angeles style cloverleaf in terms of the dizzying number of possible destinations. So how did our current and future plans for the path of the Cassini spacecraft come to be? That's the question Dave Seal put to me since that's my job -- I am a tour designer.

Canto III: Hints of Equinox

Posted by David Seal on 2009/06/04 06:31 CDT

Saturn is rapidly approaching equinox, where the Sun passes through the ring plane (south-to-north, i.e. the northern vernal equinox), and its ring system (i.e. its great now-gloomy poorly-lit circles of large blocks of water ice) is starting to show some really interesting behavior.

Saturn, Tethys, and Titan

Posted by Emily Lakdawalla on 2008/03/25 12:37 CDT

I thought that today's image release from the Cassini imaging team was exceptionally pretty.

A way-cool Cassini picture: rings, Titan, Dione, Prometheus

A couple cool raw Cassini pics -- and a break in the data

Posted by Emily Lakdawalla on 2005/07/19 04:56 CDT

I monitor the Cassini website to keep my eye out for cool pictures, and it's usually relatively easy to figure out what the spacecraft is looking at (rings, moon, Saturn, whatever). Sometimes, though, the images can be very confusing.

A couple of pics from Cassini at periapsis

Posted by Emily Lakdawalla on 2005/06/27 08:20 CDT

Cassini's been in orbit around Saturn for almost exactly a year now, and the mission seems pretty much to have dropped off of the public radar screen. But there's still three years to go on the primary mission, and lots left to do, and I for one am not at all bored.
