Umm... how about Lucaria Tholus? OK, yeah. That's what I thought. But according to the planetary names folks, they are playing by the rules: Tholus, tholi (TH) - Small domical mountain or hill. Maybe they need a new feature name. What's Latin for "bump"?

Early on in the Vesta orbital phase, the Framing Camera operations team, far more concerned about correct orientation of the images and meaningful navigation than about scientific or toponymic soundness, concocted a series of informal names that mainly served the purpose of designating easily identifiable features. One of these nicknames was "The Snowman", which has now become part of the popular culture about Vesta. Another one was "Dark Volcano".
Cheers.

"tholus" on other bodies has typically been used to denote what appears to be a volcanic construct


True! But these names are supposed to be purely descriptive, not carrying any genetic implications. I agree the term is mainly used for smaller volcanic hills, but it doesn't have to be. Possible counter-example: Scandia Tholi, Mars, a rag-tag collection of hills that don't look like volcanic shields or cones to me.


Also - new names added on Tuesday:

Yes, and they have now released over 200 pictures of the day.

In LAMO, Dawn seems to be taking only nadir-pointing images. At least, those that were published are of this type, unless I missed something. Do they sometimes slew the spacecraft in order to take oblique images?

LAMO is all about the composition-mapping instrument, with imaging just riding along. They have to look down pretty much all the time, I think.

I can confirm Phil's comment. As Marc Rayman has mentioned several times on his blog, the Gamma Ray and Neutron Detector (GRaND) is the prime instrument in this phase. This instrument will provide the elemental composition of the surface (up to 1 meter depth) thanks to the nuclear emissions induced by the background cosmic radiation. The problem is that these emissions are very weak, and even with a detector as finely tuned as GRaND it requires an extremely large amount of integration time to get above the noise.
The off-nadir imaging, which is critical for the stereographic reconstruction of the surface, will continue in the second HAMO phase later this year.

A really nice "uber"-image release today, with lots of neat related image and caption releases:

A gorgeous shot of Aquilia: http://dawn.jpl.nasa.gov/multimedia/aquilia_area_color.asp

(obviously the result from a Pocket Tanks Chaos Grenade)

I suspect that the news conference is timed to coincide with DAWN results being printed in this week's upcoming issue of Science. I went to the lecture at Caltech last week and Carol Raymond mentioned the publication, and artfully dodged at least one question from the audience that apparently would have prematurely revealed something that will be included in the articles.

I have been collecting the "special issues" of Science on the planetary missions for the last 20 years. The articles are a bit of a tough read compared to something more mainstream like Scientific American, but it just makes me feel a bit closer to the real discovery process.

For anyone not aware of it, you can locate back issues at http://www.sciencemag.org/content/by/year.
And, after a lot of searching, you can find how to order issues at: http://www.sciencemag.org/site/help/readers/order.xhtml

For some reason I have had mixed sucess with the online forms, sometimes I get acess and can do it online, and sometimes end up with a hard copy PDF file instead. When that happens I just call the toll free number and do it the old fashion "talk to someone" way.
