Re: Rosetta lands safely on comet
OK. So I'm late to the thread, but I must ask how they could possibly have landed a spacecraft on a comet, which is made up of ice and space dust? An asteroid I could understand. It is a solid substance; but a comet?
Could someone please educate me?

Might it be that the comet is shaped like a duck; and as far as I know, a duck is solid.BobH wrote:Could someone please educate me?

Re: Rosetta lands safely on comet
Judging by the pictures, the surface of the comet is rocky (although it's probably low-density rock).
Best wishes,

OK. You win. Stuck has convinced me that this is "no-argument week". (Let's see how long that lasts ...)Rudi wrote:I'd say that would be a grain of a grain of a grain of sand to hit a frozen avocado pip at a distance of 317.01 km
Of course, now I feel a faint blush to my cheeks on learning that
(a) it bounced
(b) the drills didn't "instanter" screw in to prevent it bouncing
(c) it is escaping the brutish heat of the sun by hiding under a cliff and hence
(d) for all I know it could be dead by the time I click Preview and then Submit.

Re: Rosetta lands safely on comet
The Philae lander has been turned off for the moment, since its batteries ran out. Perhaps it'll be revived when the comet is nearer the Sun - the solar cells may then be able to generate more energy.

That didn't take us very far, did it?
In Monty Python and The Holy Grail it was established as fact that a duck is made of wood.

I know its not the most amazing fact Chris, but if you've ever eaten duck, you will know that it needs to be chewed before you swallow.ChrisGreaves wrote:Well!Rudi wrote:... as far as I know, a duck is solid.

I've never eaten a swallow either, I guess you have to duck before eating one of those.Rudi wrote:...

I suspect you'd have to duck if someone swallowed a duck too quickly ...StuartR wrote:I've never eaten a swallow either, I guess you have to duck before eating one of those.

Geese? Swallowing a goose is more work than swallowing a duck...

Re: Rosetta lands safely on comet
Wow, that goose looks suspiciously similar to the shape of comet 67P/CG.
