Enceladus: A problem of contrast

Emily Lakdawalla • January 30, 2013

Time for my quarterly foray into the Cassini archival science data! The very first image I downloaded from the January 1, 2013 data release presented an interesting challenge to my image processing skill. I'll show you the pretty picture of Enceladus and then explain how I processed it.

Weather Report: Mars

Bill Dunford • January 28, 2013

Voyager 1 revisited: Io and Europa transiting Jupiter

Björn Jónsson • January 22, 2013

What is the highest resolution global Jupiter mosaic that includes a satellite transit that can be assembled from Voyager images? Satellite transits are especially beautiful when the resolution is high enough for some details to be visible on the satellites so I decided to check this. And I was remarkably lucky.

More Chang'E 2 Toutatis flyby images

Emily Lakdawalla • January 20, 2013

Last week at a meeting of NASA's Small Bodies Assessment Group (SBAG), Han Li of the Chinese Academy of Sciences gave a lengthy presentation on Chang'E 2. Her presentation included a new sequence of photos from the December 13 Toutatis flyby.

My ever-popular asteroids-and-comets montage, now in color, with bonus Toutatis

Emily Lakdawalla • December 18, 2012

My collage of all the asteroids and comets visited by spacecraft is probably the single most popular image I have ever posted on this blog. I've now updated it to be in color and to include Toutatis.

Blast from the past: Mariner 4's images of Mars

While hunting for photos to use in a presentation, I came across a couple of different amateur takes on the Mariner 4 photo catalog.

Curiosity update, sol 117: Progress report from AGU

Emily Lakdawalla • December 05, 2012

Monday was the big Curiosity day at the fall meeting of the American Geophysical Union. A morning press briefing was followed by an afternoon science session. I traveled to San Francisco briefly just to attend those two events. Here's my notes on the first science reports from the mission.

Images from the long-awaited Dawn Vesta data set

Daniel Macháček • November 29, 2012

A few days ago, the Dawn mission finally published their archival data. During the year of delay I often looked with anticipation to the Planetary Data System to check whether or not images were there, and I am delighted that they are finally available. Was the wait worth it? Definitely!

That amazing image of Saturn's north pole just got better: now, it moves!

Emily Lakdawalla • November 28, 2012

Dawn Vesta Data is publicly available (for real this time!)

Emily Lakdawalla • November 16, 2012

After a false start earlier this year, the first chunk of Dawn Framing Camera data from Vesta has finally made it to the Planetary Data System. As a first step to understanding the data set, I've built some index pages to these cool images.

Pretty picture: Landsat view of southern Greenland

Björn Jónsson • November 13, 2012

This is a very large (19000 pixels square) mosaic of the fjords and glaciers of southern Greenland. I had been interested for a long time in experimenting with the processing of Earth satellite imagery just to get a comparison to the other planets.

Watching the slow shift of seasons on Titan

Emily Lakdawalla • November 06, 2012

A sharp-eyed amateur noticed two images of Titan taken 20 months apart from nearly exactly the same perspective, and they illustrate how the shifting of Saturn's seasons has brought change to Titan's atmosphere.

Getting up to speed with Curiosity as of sol 84, and two awesome mosaics

Emily Lakdawalla • October 31, 2012

Curiosity has already spent more than three weeks at Rocknest, working through the very slow process of commissioning the sample handling systems. While parked, she's taken a couple of amazing photo mosaics.

A huge color global view of Dione

Emily Lakdawalla • October 23, 2012

Astrophotos making the web - the good, the bad and the ugly ...
