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 trio of pretty Cassini pics

Emily Lakdawalla • March 19, 2010

It's been a little while since I posted any Cassini pictures just because they were pretty, so here's a few recent ones, produced by amateurs from the images available on the Cassini raw images website.

Titan: Callisto with weather

Emily Lakdawalla • March 16, 2010 • 2

It's the second time I've posted with this provocative title. This time, it's in response to a new paper published last week in Science.

Hooray! Cassini's tour has been extended for SEVEN MORE YEARS!

Emily Lakdawalla and John Spencer • February 03, 2010

NASA has just announced that once Cassini's Equinox Mission runs out in June of this year, they will extend it a further seven more years, long enough for the spacecraft to see Saturn through its solstice!!

Planetary Society Advent Calendar for December 26: Titan

Emily Lakdawalla • December 26, 2009

Titan is a weird alternate-universe Earth, surprisingly similar to our own planet in some ways, but not at all like our planet in others.

Cassini VIMS sees the long-awaited glint off a Titan lake

Emily Lakdawalla • December 17, 2009

The Cassini mission announced today the first observation of a specular reflection off of a lake on Titan. A specular reflection is a mirror-like flash, and you only get one when you have a mirror-like surface -- very, very smooth.

Fun Friday photo: Titan and Rhea

Emily Lakdawalla • October 30, 2009

Cassini recently captured a series of images documenting Rhea passing behind Titan.

What "phase angle" means

Emily Lakdawalla • October 27, 2009

As is probably obvious by now, I love playing with spacecraft image data. I am always looking for excuses to dive into space image archives to unearth images of stuff in space that haven't really been seen by very many people before.

Fun for Sunday: Titan and Tethys pas de deux

Emily Lakdawalla • October 18, 2009

Checking in on Cassini's raw images this weekend, there are several nice shots to play with, including the many frames from which I tossed together this cute animation.

Changes in Titan's southern lakes

Emily Lakdawalla • October 06, 2009

Today's science press release out of the Division of Planetary Sciences meeting concerns changes in lakes near Titan's south pole observed during Cassini's mission. In brief, repeat Cassini RADAR observations of the same spots during different Titan flybys turned up places where there appeared to be dark lakes in earlier images and dry lakes in later images.
