LAMO, aka Low Altitude Mapping Orbit Options

[dilo]

I think is time to start this new topic, now that Dawn is more than half-way in the transition from HAMO to LAMO (as showed in the plot below).

Three releases on the multimedia page that would seem to indicate there will be a release / NASA news item about long-lived ice on Vesta.

Ah, yes, this release:

Also, today's image:

Comparing Vesta's axial tilt of 27 to Ceres with 3, would Ceres be much more likely to retain ice at the poles. Could vapor sublimating from the equatorial regions on Ceres be deposited as layers of frost at the poles, perhaps forming ice caps, or is the surface gravity far too low for this to occur?
