Does anyone know, what happened to Dawn's FC raw data? Data release was scheduled for 1.3.2012 (more than one month ago) and PDS is still empty. Some problems with calibrations or something similar?

No, much more complicated. There is a disagreement over certain aspects of the documentation and PDS will not ingest the data until the situation is resolved.

I talked with several scientists at LPSC about this and while we won't see it at the PDS any time soon, they all told me I should go ahead and play with the data and encourage others to do the same. I have all the released FC data. When I can find time to work with it I'll make chunks of it available. But we're in the middle of a complete site overhaul just now and I don't have time to play

"When I can find time to work with it I'll make chunks of it available."
That would be nice! I have only few images from 11.8.2011. -------------------- |

According to http://pds-smallbodies.astro.umd.edu/data_...ase_sched.shtml, it seems that we still have to wait only few days (Finally !?)

May not be reliable. I don't think the underlying issue has been dealt with yet.

Water on Vesta, that's a surprise.

I don't find it surprising. There's water ice almost everywhere except on exposed planetary surfaces. Plenty on Mars, over a wide range of latitudes. The next large objects are the Jovian moons. Only one is non-icy: the rest are mainly ice.
I think all the big asteroids will have a lot of ice, though mostly sub-surface. Apart from ice incorporated when they formed they may also have ice originating from later comet impacts. Visible ice may indicate nothing more than recent exposure. |

still more papers on Dawn at Vesta in today's Nature (sorry, I don't know whether this is the good topic):
Distinctive space weathering on Vesta from regolith mixing processes Dark material on Vesta from the infall of carbonaceous volatile-rich material |

And now for something completely different - Dawn data in the PDS!
Few experiments from images FC21A0003204_11205081617F7K, FC21A0003199_11205081516F2K and FC21A0003205_11205081627F8K (all 24.7.2011) First image is with "normal" colors (I don't know how close is this to true colors, but its from filters closest to RGB standard). Second image is with saturated colors. All images are rotated 180° to the right, so Rheasilvia is on top.
