Planetary Society Advent Calendar for December 25: Double planet

Emily Lakdawalla • December 24, 2009

To those of you who celebrate the holiday, merry Christmas! I hope Santa was good to you.

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."

Opportunity's poking at Marquette Island; Cassini's catching dancing moons

Emily Lakdawalla • November 18, 2009

Since tomorrow's class is going to be on playing with raw images from the rovers and Cassini, I've been playing with recent raw images from the rovers and Cassini! I just thought I'd share a couple of the fun items I've been working with.

Four moons and a ring

Emily Lakdawalla • November 10, 2009

Thanks to Mike Malaska for the tip on this one. The image is part of an animation that ends with Rhea transiting Saturn.

Another marvelous image from Cassini's Nov 2 Enceladus flyby

Emily Lakdawalla • November 03, 2009

This image goodie was produced from the raw images from Cassini's close encounter with Saturn's geyser moon Enceladus yesterday by Gordan Ugarkovic.

Fun Friday photo: Titan and Rhea

Emily Lakdawalla • October 30, 2009

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

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.

MESSENGER gets two planets for the price of one

Emily Lakdawalla • October 02, 2009

Here's a pretty shot of Mercury taken by MESSENGER on approach...but wait, what's that tiny little speck in the lower left corner of the photo?

Cassini RADAR continues to gaze at Titan

Jani Radebaugh • July 27, 2009

The Cassini spacecraft made its 59th flyby of Titan, Saturn's largest moon, on Friday, July 24, and in the last few hours we have received images from the RADAR instrument in SAR (Synthetic Aperture Radar) mode.

Canto III: Hints of Equinox

David Seal • June 04, 2009

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.

Farewell to Hubble, Obama Calls, Astronauts Testify to Congress as Shuttle is Set to Land

Fly me to the Moon...

Jim Bell • May 04, 2009

Jim Bell describes his proposal to join the Lunar Reconnaissance Orbiter Cameras science team.

Welcome to the Solar System, Makemake

Emily Lakdawalla • July 15, 2008

The trans-Neptunian object formerly known as 2005 FY9 now has a name: "Makemake."

Saturn, Tethys, and Titan

Emily Lakdawalla • March 25, 2008

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

New Horizons' raw images are now online

Emily Lakdawalla • January 23, 2007

I got an email from John Spencer this morning telling me that the mission had posted all of New Horizons' most recently acquired images on the mission website.

New Horizons is targeting Jupiter!

Emily Lakdawalla • January 10, 2007

New Horizons' Jupiter encounter is officially underway!

The Orbital Dance of Epimetheus and Janus

Emily Lakdawalla • February 07, 2006

Saturn is surrounded by a crowded family of rings and moons, and two of those moons -- Epimetheus and Janus -- orbit Saturn so close together that it seems as though their different orbital speeds should make them crash into each other.

Cassini, Day By Day

Emily Lakdawalla • January 02, 2006

I've just resurrected a feature on the site that has been lost since our redesign: the "Cassini, Day By Day" pages.

Pretty Cassini pictures from near the ring plane

Emily Lakdawalla • December 09, 2005

It's been a while since I posted some Cassini pictures here just because they were pretty.
