There are two very interesting papers on adaptive optics observations of Lutetia on arXiv today: Physical properties of ESA/NASA Rosetta target asteroid (21) Lutetia: Shape and flyby geometry ... From first article I made this rough animation of the rotating asteroid (time intervals aren't proportional): North is up/above image plane EDIT: I removed second frame in order to have more fluid/consistent rotation -------------------- I always think before posting! - Marco -

Well, since it is the Latin name for Paris, I would defer to our French members. I'm from Italy and I studied LAtin at school. I think "LOOT-eh-shee-ah" is wrong due to the "H" in "shee". I think the best aproximation in your proposals is "loo-TET'-see-ah ", as the second T must be read as a Z; I mean, "Lutetia" would be "Lutezia" in Italian. Unfortunately looks like you have no "Z" sound in English, so you need to "aproximate" it by "ts", just as you like when saying "grazie" (="thanks"). |

Both German and Italian use the letter Z to represent the "ts" sound. Strange that both languages' orthographic systems have this feature, since German and Italian are not that closely related within the Indoeuropean language family. Perhaps their time joined together under the Holy Roman Empire was one reason for this shared orthographic feature.

Rosetta Right on Target for Lutetia flyby
http://webservices.esa.int/blog/post/5/1223 QUOTE With the latest orbit determination and following the flight rules, there will be no manoeuvre [needed] at the TCM [trajectory correction manouevre] slot 40 hours before the flyby. Also, it is considered that there will be no need to use the manoeuvre slot at 12 hours before the flyby, unless a anything changes. Gentle reminder that it's in 3 more days... -------------------- -- Hungry4info (Sirius_Alpha)

Love this quote from the Planetary Society blog
QUOTE Mindful of media interest in the encounter -- but also of the World Cup schedule -- ESA plans to have the first black-and-white images prepared for public release around 21:05 or possibly later if the Third Place match runs into overtime.

The ESA operations center ESOC is in Darmstadt, Germany, and Germany is in that game against Uruguay. So I guess they want to avoid publishing that "spherical leather-like surface with hexagonally shaped canyons" as the surface of Lutetia.

any new image of the approaching?!?
which "on ground" resolution will the onboard camera be able to reach? |

They won't actually resolve Lutetia as an object with a shape until hours before closest approach, so while they could technically be posting more approach photos, they wouldn't really look any different from the ones already posted.

Looking forward to this flyby as it will add yet another asteroid to the list of objects visited by a spacecraft and studied up close. Will Rosetta be taking other measurements of Lutetia apart from images?

Enceladus75, the answer to your question was posted earlier today on Rosetta's excellent official blog.

Will Rosetta be taking other measurements of Lutetia apart from images? Yes, IR mapping spectroscopy, thermal mapping, UV coma searches, UV reflectance spectroscopy, magnetic field search, the list goes on... |
