just got connected to webcast after meeting - did I miss the landing or did it tank?
Confirmation of contact with the comet at 1609 GMT. Harpoon fired and retracted to haul lander to surface.

Star had yet to experience strippers who crash cars into houses...
1.) Were there any electrical discharges on final approach like last time?
2.) Any indication yet whether this one is an actual dirty snowball instead of basically an asteroid?
There are some interesting scientific paradigm questions being thrown around recently about how comets actually operate.
Very cool graphic of the trip to the comet.....

No data on Liv Tyler and animal crackers?
believe me.
if you landed on Liv Tyler the world has truly ended.

I'd accept that end.
What if mirth took the Low Countries and then Liv? Or Lvov?
I'd go for an anschluss with Liv.
I dont think his gf would like that very much.

If the Germans tried to invade again this time they would march into the Red Light District and never be seen again.
the rules there have had a drastic overhaul.
so Ive heard. ::)

a lot of other European nations had there contribution too, its amazing that it worked (more or less) nevertheless ;-)
its amazing! that's not X-Rebirth , Elite Dangerous or Kerbal ...we all witnessed the real deal 8)
race to an object that is 28 light minutes away, not just hit it, but gentle approaching it in a way to swing into an orbit where nucleus gravity let a 100kg object on Earth feels a gravity pull of just 1 Gramm... and then ballistic drop a
'bomb' probe on that irregular rubberduck shaped rotating object of 4x2x2 km with precision to place a hit into a 400m circle. 8)
unfortunately the lander is not anchored
well, it still feels a gravitational pull of 1gramm , so i think it will stay or gently retouch if it had re-bounced somehow
and was floating
analzing the last press infos that got public available between the lines, i guesstimate it landed in 'a powder snow'-like soft material and is partially submerged ...the harpoons either didn't got triggered (to smooth impact) or fired into powder
consider the whole commet has a density of 0.4 g/cm^3 ...and the landing spot was selected to be smooth surface as far as the pictures allowed an estimate.
yesterday eve the LOS between Rosseta and the lander was interuppted while Rosetta orbit takes it to the other side of the commet. we will have new data packages now while Rosseta has rizen above the lander side again
XKCD has a hilarious animated version of the live landing

That is great!
I especially liked that they thought to include whales in the whole thing.
^That made me think of the poor falling whale in Hitchhiker's Guide to the Universe.
My thought exactly. They included fish an dolphins, too. Sounds like someone knew what they were doing ;)

new images taken during the landers descent were recently released. Some taken from a distance of 9m!
fantastic news to hear that Philae recently woke up and phoned home. Sounds like there is hope the charge will continue to improve as the comet approaches the sun.

I'm thrilled it woke up. Much to learn there!
First being, is it really a dirty snowball? Or more of an asteroidish composition?

Dusty rock ball methinks.
Even a dusty rockball would change theories of how the tail is generated.
In a possibly trivial aside, I didn't notice any talk about eruptions creating a tail during the approach. (Though we've been through this already with the prior comet that we sent an impact probe to -- not a landing per se of course, but still an impact. Basically the comet was an asteroid in composition.)
Besides the ice dust, there is water and gases trapped in the rock IIRC. So when it heats up, the various frozen liquids expand and evaporate into gas, shooting out. That's where the tail comes from. But there's generally still a fair amount of rock & dust in many of them, from what I've read.
It's also one of the popular theories proclaiming the Tunguska event to be caused by a small comet. Air bursting over Siberia after it's icy gases were heated so quickly upon passing through the atmosphere that it exploded like a huge dry ice bomb in a plastic bottle. 8)
I've seen estimates of early comets, from shortly after the planets formed, containing something like ~10% water. So I get the impression that the gas and liquid stuff still don't make up the majority of many comets.. just notably higher than asteroids. I'm sure there's a fair bit of variance, especially between comets from the Kuiper Belt or the rarer slowbies from the Oort cloud.
