ESA astronaut Frank De Winne - off topicYes, yes: it's a little off-topic for the VMC blog, but this is waaaay cool! ESA astronaut Frank De Winne has agreed to accept video questions posted as a response to his invitation in YouTube. And get this: he's agreed to post answers to selected questions from his training location in Moscow or from space - on board the ISS once he launches (now due for 27 May). Access the full YT video after the jump...

We now return to our regular Mars Webcam blogging. :-)

March 19, 2009 Cloud Detail (Personal Project for 100 Hours of Astronomy, April 2-5 IYA2009)
To make this image, several MEX-VMC images acquired on March 19, 2008 were used, specifically:
09-078_19.26.32_VMC_Img_No_2.png, 
09-078_19.27.25_VMC_Img_No_3.png, 
09-078_19.29.12_VMC_Img_No_5.png and  
09-078_19.30.05_VMC_Img_No_6.png. 
All the images were aligned and resized in Photoshop.  The two darkest images, No. 2 and No. 6 were averaged (No 2 at 50% opacity).  Contrast was adjusted to bring out cloud detail in the non-overexposed region.  Then image No. 3 was added to the stack, and a fuzzy layer mask added to image No. 3 that corresponded to the overexposed portion of image No. 3, yet would allow the grays of the No. 2/No. 6 combination image to show through.  Next, the brightest image No. 5 was added, with a fuzzy layer mask added that corresponded to the overexposed portion of image No. 5, yet would allow the grays of No. 3 (and also No. 2/No. 6 combination) image to show through.  This stack was contrast enhanced using curves and levels.  This image was then Gaussian blurred gently (0.4 pixel), then an Unsharp mask was applied.  Residual color information was removed using a Black & White adjustment layer.  A camera artifact near the crescent edge was removed using clone stamp and a Gaussian blur of a selected region.  Finally, a second contrast adjustment was performed using Curves and Levels.  With this technique, the full detail of the cloud patterns observed by the MEX-VMC camera can be revealed across the crescent Mars.

USAOur first public submission of the new VMC blog comes as part of the International Year of Astronomy project - 100 Hours of Astronomy. Mike Malaska of North Carolina, USA, decided to work on the latest batch of VMC images as part of his contribution to this project. Mike's work really brings out the detail of the cloud dynamics swirling above Mars in the latest photos - read on to see how he did it.
