Dusty girl

Posted by Emily Lakdawalla on 2012/01/23 05:32 CST

Today Opportunity sent back to Earth the last few frames of the "deck pan" self-portrait she took during the waning days of 2011. Her solar panels are very dusty, which isn't helpful. It's near winter solstice in her southern location on Mars, so the angled Sun is not providing as much power as it would in a different season.

A Tale of Two Martians

Posted by Jim Bell on 2012/01/09 11:15 CST

It's the best of times for Mars exploration because we've got three orbiters and a rover studying the Red Planet. It's also the worst of times for my Russian, European, and Chinese colleagues who were part of the Phobos-Grunt mission.

The Making of Martian Clouds in Motion: Part 2, tweening the animation

Posted by Emily Lakdawalla on 2011/08/28 06:14 CDT

Two weeks ago I posted an awesome video of Martian clouds in motion. Last week I explained how I accessed the Mars Express images that comprise the animation. Today I'm going to explain how I turned the five-frame animation of Mars Express images into a smooth movie.

The Making of Martian Clouds in Motion: Part 1, working with Mars Express HRSC data

Posted by Emily Lakdawalla on 2011/08/22 08:39 CDT

Last Friday I posted an awesome video of Martian clouds in motion. This week I'll tell you how I made it. The how-to is split up into two parts. The first, today, is how to access Mars Express HRSC image data and process it into the individual animation frames, from which you can make an animated GIF.

Gale's not the only Martian crater with an "enigmatic mound"

Posted by Emily Lakdawalla on 2011/08/17 07:33 CDT

Much has been made of the "enigmatic mound" within Gale crater, which will be the target of the Curiosity Mars rover's investigations. The 5,000-meter-thick section rocks in Gale's central mound will be fascinating to study, but the fact that Gale has a central mound that's taller than its rim is not at all unusual on Mars.
