Mass concentrations is an interesting hypothesis. Any way to test any of this? i had not thought of unequal mass distributions as a posible cause of the "flow lines" (but i had thought perhaps they might be fingerprints of the "person" who made this snow ball. rather big hands. anything match in the FBI database?) i do see the resemblance to hair growth.
if the flow lines are ice from Enceladus, what colected that ice into lines? the most likely force i can think of is gravety.

Hi NeKto
I have not been here for a while. That is true, perhaps the flow lines could also indicate mass concentrations within Helene.
I also understood that the flow lines could also be from ice swept up from the geysers on Enceladus. The Tethys tojan moons Telesto & Calypso are also largely covered in fine ice & Calypso too shows hints of flowlines. Would be interesting to get a close up of Polydeuces if possible too, the other Dione trojan moon, the one that trails Dione. Polydeuces is only about 3.5 KM wide at most, so Helene is very much larger.

Andrew, at first glance i thought the flow lines were all pointing to the low spots. not radiating out but flowing down. i find such fetures fascinating on non hydrodynamicly stable objects. they might tell us something about what happens as mass of non stable objects increases during acretion.
I agree with Andrew, what an unusual feature on Helene. Looks like something hit her recently.

Wow interesting views of Helene :) The curious flow like features seen from a far northern viewpoint are interesting, they appear to radiate from a point like hair growth from a crown on someones head!!!!
