No information just a sign up page and the same thing with launchrock.com. Not very helpful. anyone have any other info on this?

Here's the more information. http://news.ycombinator.com/item?id=3713941

I was thinking a desktop background version.

yea but saturn's rings are made of ice, moons and planets are made of rock just like asteroids not ice like comets.

Saturn's rings are made of the exact same stuff as its moons, because that's what they are. One or more of Saturn's moons broke up millions of years ago under gravitational/tidal forces, and over time the debree spread out into a ring.

And BTW, there are plenty of examples of moons made of ice, and at the temperatures of the outer solar system ice can be harder than rock (and BTW, Neptune and Uranus are called "ice giants"--care to guess why?).

what's the difference between rock and ice? is there a boundary where if the melting point is below a certain value then the substance is ice, and if it's above that value it's rock? it's not like rock can't melt in the right circumstances.

Ice is made of small molecules like water, methane or carbon dioxide.

is there a concrete cutoff or shades of grey?

I think what the GP is getting at is the chemical difference of ionic minerals (rock) vs amorphous collections of molecular compounds (i.e. water or methane ice). There is a categorical difference between the two chemically, although as an aside their properties in micro-gravity and the cold vacuum of the outer solar system are quite different from what you might have learned in your chemistry class.

hahahaha he means serious business.

That is awesome!!

HAHA. As corny as it is presented, it is very informative.
