The Planetary Society and Cosmoquest have teamed up to offer a short course in space image processing, and I'll be teaching! The course comprises four one-hour sessions from October 14 to 23.
One of my favorite image processing tricks: colorizing images
Posted by Emily Lakdawalla on 2013/04/23 02:11 CDT | 2 comments
An easy image processing trick -- using lower-resolution color data to colorize a black-and-white photo -- is relied upon by many space missions to keep data volumes low. Here's how to do it.

Виталий Егоров (Vitaliy Egorov) is a Russian space enthusiast who enlisted help of fellow enthusiasts to search for -- and maybe find -- the Russian Mars 3 hardware on the Martian surface. Here he explains how he did it.
Browse Curiosity's data in the Analyst's notebook
Posted by Emily Lakdawalla on 2013/03/05 01:29 CST
Last week the Curiosity mission made its first data delivery to the Planetary Data System. The bad news: none of the science camera image data is there yet. The good news: there are lots and lots of other goodies to explore.

Last week I trawled the archives to find all of Galileo's images of asteroid Ida; this week, I turned to Gaspra.
Browsing Landsat data is a lot easier than I thought it was
Posted by Emily Lakdawalla on 2013/02/08 05:05 CST | 2 comments
With the Landsat Data Continuity Mission scheduled to launch on Monday, there's been a lot of Tweeting about Landsat, and through one such Tweet I learned about a resource that I hadn't known existed before: the LandsatLook Viewer. This is a graphical interface to more than a decade worth of Landsat data, a tremendous resource for anyone interested in Earth's changing surface, natural or manmade.

Enceladus: A problem of contrast
Posted by Emily Lakdawalla on 2013/01/30 07:00 CST | 6 comments
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.

Images from the long-awaited Dawn Vesta data set
Posted by Daniel Macháček on 2012/11/29 11:55 CST | 4 comments
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!
Dawn Vesta Data is publicly available (for real this time!)
Posted by Emily Lakdawalla on 2012/11/16 07:08 CST | 2 comments
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
Posted by Björn Jónsson on 2012/11/13 05:24 CST
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

Posted by Emily Lakdawalla on 2012/10/03 07:15 CDT | 2 comments
Curiosity has been shooting photos of the Sun as Phobos and Deimos cross its face, and -- as far as I can tell -- captured sunspots as well.
