Doug Ellison shared this lovely panorama via Twitter over the weekend. It's from the Mars Exploration Rover Spirit, taken back in 2004. The drunken path in the foreground is a visual record of just how exciting it was for Spirit to have finally made it to the Columbia Hills, and to rocks that were not fragments of basalt.

Galileo got so many more images of Ida than I realized
Posted by Emily Lakdawalla on 2013/02/22 04:14 CST | 1 comments
While writing up the cruise-phase issues of the Galileo Messenger a couple of weeks ago, I came across a fuzzy montage of images of Ida that I had not seen before. So I decided to spend some time digging into the Planetary Data System to see if there were more images to be found. I found lots and lots pictures that I'd never seen before!

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.
