Book Review: The International Atlas of Mars Exploration, by Phil Stooke

Posted by Emily Lakdawalla on 2012/10/12 04:31 CDT | 3 comments

I've been waiting for the publication of this book for years. Phil Stooke's International Atlas of Mars Exploration, just published by Cambridge University Press, is an exhaustively awesome labor of love, chronicling the first five decades of Mars exploration in pictures, maps, and facts.

Notes from the Lunar and Planetary Science Conference: A little bit of Phobos and Deimos

Posted by Emily Lakdawalla on 2012/03/22 12:04 CDT | 3 comments

I just sat in the "small bodies" session at the Lunar and Planetary Science Conference, listening to three talks about Phobos. The first was by Abby Fraeman, who looked at data on Phobos and Deimos from the two imaging spectrometers in orbit at Mars. The next talk, by L. Chappaz, was motivated by Phobos-Grunt's mission. It asked: if you grabbed 200 grams of soil from the surface of Phobos, how much of that material would actually have originated on Mars? Then there was a particularly interesting talk that dealt with the question of how Phobos' grooves formed.

Has Mars Express MARSIS data proved that Mars once had a northern ocean?

Posted by Emily Lakdawalla on 2012/02/07 05:46 CST

There's been a bit of buzz on the Web this week regarding an ESA press release titled "ESA's Mars Express radar gives strong evidence for former Mars ocean." I don't ordinarily write about press-released science papers, but am making an exception for this one.

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.

Update: Phobos and Jupiter and its moons!

Posted by Emily Lakdawalla on 2011/06/20 03:53 CDT

Remember that neat picture and movie of Phobos passing by Jupiter that I posted last week? Several people asked me where Jupiter's moons were, and I just assumed that they weren't visible. I was wrong; Mars Express spotted Jupiter's moons along with the planet and Mars' moon!

Watching Phobos pass by Jupiter

Posted by Emily Lakdawalla on 2011/06/17 09:27 CDT

Here is a really cool view of Phobos in the foreground with gigantic (but very distant) Jupiter sitting in the background, a fortuitous alignment that the Mars Express High-Resolution Stereo Camera team took advantage of on June 1.

What's up in the solar system in April 2011

Posted by Emily Lakdawalla on 2011/03/31 03:59 CDT

April 2011 will see MESSENGER begin the science phase of its orbital mission at Mercury, and should, I think, also see the start of Dawn's approach observations of Vesta. At Mars, Opportunity is back on the road again, rolling inexorably toward Endeavour. At Saturn, Cassini will continue its focus on Saturn and Titan science.

What's up in the solar system in March 2011

Posted by Emily Lakdawalla on 2011/02/28 02:43 CST

I don't think there's any question what the big event of this month will be: MESSENGER is finally, finally entering orbit at Mercury on March 18 at 00:45 UTC (March 17 at 16:45 for me).

How Mars Express' orbit shifts with time

Posted by Emily Lakdawalla on 2011/01/04 11:02 CST

While I was writing yesterday's blog entry on Mars Express' Phobos flybys I realized that I didn't understand Mars Express' orbit very well. So I sent an inquiry to the Mars Express blog, which they answered in a blog entry today.
