Hi,
I’m regular follower of NH and I’m also interested in the 2nd leg of the mission, i.e the 2016+ KBOs encounters. Does anyone know when operations about this leg (starting with searching objects of interest with HST or some other earth-based means, I suppose) are expected to begin ? |

Light curves are useful for many things.
This is citation from abstract Rotation Periods of Irregular Satellites of Saturn, which describes observations of small irregular moons from Cassini. "Motivation is the determination of basic properties of these objects like rotation periods, polar axes orientations, object sizes and shapes, phase curves, colors, or the search for binaries." Another field of research is about asteroids and analyzing their light curves for determination of their physical properties. I saw comparison between two shape models of Lutetia. One was obtained by modeling from light curve and second from Rosetta OSIRIS camera. Both of them were almost identical (basic shape in low resolution). High phase observations are useful for Hapke modeling of surface properties as surface roughness etc. But I think that usefulness of this technique strongly depend on quality and quantity of images. -------------------- |

Motivation is the determination of basic
properties of these objects like rotation periods, polar axes orientations, object sizes and shapes, phase curves, colors, or the search for binaries reads like amazing blank verse. |
