I needed to track down the problem of the pixel shift which hit some images (now fixed!)

Does that mean I don't have to update the software to figure that out and correct it automatically?

Sure thing...sorry ugordan, that was my mistake...I'm the one who needed to correct it wink.gif There shouldn't be any more images with the pixel shift - although it'll take a while before we can update the archive with the new raws I'm afraid.

Hey, these things happen. I messed up a fair share of Cassini images myself with subtle bugs in my software wink.gif

Normally, I'd say don't bother as it would be faster to implement a software fix instead, but I'm a bit uneasy about the method I had in mind. I.e. if it could produce some other unwanted side-effects.

Yeah, I think it's best to do the whole archive systematically because it corrects a "wiggle" in the images that you can actually see stepping through old image sets that have the bug - the planet jumps sideways from one image to the next due to the pixel shift. On top of that I'd also like to get the whole library redone with the new processing methods, I'll work out an automated update method and then set it running on the archive. Thanks as always for the help though!

More limb shots with clouds in cross section!

http://webservices.esa.int/blog/resource/6/12034

EDIT: Tried a quickie technique of taking the one image (No. 7), flipping it, then subtracting it out to cancel the bright limb, then adding in slightly the original image. Clouds enhanced, but ignore all surface features, they are artifacts of the subtraction process.

Hi all!

Things have been a little quiet on VMC of late (but I see you were all enjoying our Phobos campaign not so long ago!) but we've been preparing something a little special and it's my pleasure to announce that it's now live on the VMC blog.

On Mars Express orbit 8194, 27th May 2010, we commanded the spacecraft to capture VMC images at the maximum rate for an entire 7 hour elliptical orbit of Mars Express. The images were captured at two exposure settings, alternating between brighter and darker, producing a total of 300 images at each exposure setting.

We've managed to upload all this and generate some rough movies from the sequence in time for the 7th anniversary of the Mars Express launch today. As always with VMC the full raw dataset has also been posted on the website so go ahead and download it! For those who don't know, the blog can be found here: http://webservices.esa.int/blog/blog/6.

At the top of the blog you can see one of our first videos of the sequence and then the two part post below ("New Images From 27 May 2010 Added") shows the full image sequence and gives you the link to download the raw data.

There are loads more details on the website so do take a look, but we've always been so impressed with the quality of the work by UMSF that we thought we would give you a special heads-up. Enjoy looking through the images and as always send us your interpretations of the data at the usual address (look at the "Help us with VMC" section of the VMC website for more details). Whether these are arty, technical, scientific or educational...still photo or video...send them over and we'll publish the best.

Above all enjoy this exciting new Mars Express observation!

That's great! And you even caught Phobos zipping by at the end. I tried clicking to enlarge a few of the later image thumbnails but that didn't work. (Maybe it's not supposed to?? - I don't really want to download all 40 Mb though.)

There's a superfluous quotation mark at the end of the thumbnail links, you can manually delete it until they fix it.

Fixed! Thanks for the quick catch on that one!

As you can imagine this is quite a lot larger (~10 times) than any other set we've posted to the blog before so it required a bit of manual wrangling with the posts to get it to all display wink.gif

My attempt at overdramatisation in putting the video on YouTube (not to worry, everyone got credited appropriately).
