LSD Helene

I initially read that as "Latin Square Design" -- clearly a bit too immersed in the world of stats smile.gif

Definitely a really cool pic -- I think back to the pictures from Pioneer and Voyager, which gave us only a hint of things to come.

OK, this is just fooling around, it doesn't mean anything, but an eyecatching view anyway. What would the great mountain ranges of Helene look like from a viewpoint on the opposite side of the valley?

Just for fun: Assuming a free-fall drop of 2 km and using Heleneís gravity figure below (1/5000th that of Earthís), ballpark figures for your skierís terminal velocity speed would be less than 10 km/h after a 20 minute run-out

A few will take this knowledge and use this power of a dream realized as a force for change, an impetus for further discovery to make less ancient dreams real.

Great work. And in way I'm even more impressed by the enhanced color composite than the movie since it can be extremely difficult to perfectly align the color channels for closeups of an irregular, small target like Helene.

It's never perfect for irregular bodies, but it can be done with ImageJ + UnwarpJ or via manual warping. I used both methods in this animation.
