They are saying Rosetta is now in a heliocentric orbit matching the comet's, on the sunward side, and will continue to move along at 100km distance without orbiting
the comet for some time yet. Being closer to the sun its orbital velocity is naturally somewhat greater, and it slowly gains ground moving ahead of the comet. Every 4 days or so they brake and fall back behind the comet, then catch up again, describing a triangular path which maintains the 100km distance. Looking forward to some new pictures... |

Is the rotation period known?
Or where can I find images with original timestamps? |

I was putting together a final approach animation - but there are a lot of unreleased NavCam images..
So I slowed down the final 5 frames of their animation to allow a better look http://i.imgur.com/LiPmKB1.gif EDIT: My 1 image per day approach version : http://i.imgur.com/VuYZN78.gif |

Possible landing sites marked as green spots on illumination model of shape model (Youtube)
There's a coordinate system and poles marked on that animation, too. -------------------- My website - My Patreon - @elakdawalla on Twitter - Please support unmannedspaceflight.com by donating here.

New OSIRIS stuff in a few hours, according to the PI.
A 2D map of C-G seems like a tough order; the projection math alone...  |

What a moment in history.
And big shout-out to Astro0 for the terrific Forum banner celebrating this event!
-------------------- A few will take this knowledge and use this power of a dream realized as a force for change, an impetus for further discovery to make less ancient dreams real.

Indeed There is an incredible amount variable terrain for such a small object. Could sublimation be the cause or is it something else?
