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.

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.
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.
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.
A Mars imaging scientist answers the question: who is the "photographer" behind images returned from Mars?
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!
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.

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.
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.
New ground-based images of Uranus show more finely detailed structure than any photos I have ever seen.
Space blogger Daniel Fischer writes about the problem of composited astrophotos being distributed through social media channels by people unaware that they are artworks, not documentary photographs.
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.

I noticed today that I hadn't seen any amateur-processed versions of Voyager's departing shots of Uranus, so I decided to give it a try.
