Can't wait for the higher resolution pictures, and the landing...
Go, Rosetta, Go!!!!

Another landing coming up. I hope all the engineers have there DUCKS in a row, know how many feet are in a yard and Yards to the meter. For some reason I worry when different countries with different measurement systems get together to work on a project.

LORD POLONIUS: Yet here, Laertes! aboard, aboard, for shame!
- Hamlet, Prince of Denmark Act 1, Scene 3
- The wind sits in the shoulder of your sail,
And you are stay'd for. There; my blessing with thee!
And these few precepts in thy memory
See thou character. Give thy thoughts no tongue,
Nor any unproportioned thought his act.
Be thou familiar, but by no means vulgar.
Those friends thou hast, and their adoption tried,
Grapple them to thy soul with hoops of steel;
But do not dull thy palm with entertainment
Of each new-hatch'd, unfledged comrade. Beware
Of entrance to a quarrel, but being in,
Bear't that the opposed may beware of thee.
Give every man thy ear, but few thy voice;
Take each man's censure, but reserve thy judgment.
Costly thy habit as thy purse can buy,
But not express'd in fancy; rich, not gaudy;
For the apparel oft proclaims the man,
And they in France of the best rank and station
Are of a most select and generous chief in that.
Neither a borrower nor a lender be;
For loan oft loses both itself and friend,
And borrowing dulls the edge of husbandry.
This above all: to thine ownself be true,
And it must follow, as the night the day,
Thou canst not then be false to any man.
Just as zero is not equal to infinity, everything coming from nothing is illogical.

Through the "tidal forces" link I learnt a new word:- spaghettification. ![Razz :P](./images/smilies/icon_razz.gif)

Center of mass is in the neck, between larger body and smaller head: http://rosetta.jpl.nasa.gov/news/surfac ... %99s_comet
Overall density of the comet is reportedly between 0.1 and 0.5 g per cubic cm, depending on how calcs are done. See Wikipedia for one value, there are several others computed http://en.wikipedia.org/wiki/67P/Churyu ... erasimenko
That low a density doesn't leave much room for large rigid bodies, yet there they are. Perhaps the unusual shape has thrown off calculations?

Clearly - better pictures are on the way.
I'm sure more to follow.
