Earth from 1 Million Miles Away - Photographic Breakdown

NASA recently released an image of the earth from 1 million miles away from the DSCOVR Satellite. It shows a seemingly perfect front lit image of the earth. Personally, I never light my subjects head on (I mean, there's gotta be the photographer's shadow in there somewhere) but to each their own (sarcasm).

The image is a stitch of 3x 4MP images. The 4MP images are actually a stacking of 3 separate RGB channel images (no Bayer Array).

If you look closely, you can actually spot a few scattered hot pixels and also what looks like maybe dirt on the sensor.

Anybody have any technical thoughts on the image? What kind of images would you take if you were in space? What would be your technical approach? Maybe take your own shot on color correcting this picture. I hope NASA is listening ;)

It's freaky. It doesn't even look real. Guess you had to be there.

I can't see any hot pixels on the uploaded image, but I think I can see my house..
 
Do you have a link to the original full size image? (Or is that it, 2048x2048?)

I'm guessing some of your pixels might be burned out after you'd flown a million miles, too. :)

The camera sensor is attached to a 30mm telescope and delivers a resolution of 2048x2048 pixels so that's it.
Hot pixels are very common in space images, have in mind, those cameras are not shielded from the solar wind like we are here on earth. And add to that the extreme temperatures they experience. Cameras in the ISS are thrown away after a few years because the amount of hot pixels just becomes too high.
Even on transoceanic flights cameras get hot pixels sometimes.
