Congrats to ESA - a great job of space navigation over 10.5 years (!!) to catch up to this thing.

Comet 67P/Churyumov-Gerasimenko appears to be a composite object; two cometary bodoes that collided and fused. This should be fun.

Great, now I am imagining a control room filled with screaming scientists wearing Mickey Mouse hats!

Scientific Disneyland, Candyland, and Toys 'R' Us all rolled into one object.

 

Lovely!

Here's another size comparison: Comet 67P v Los Angeles

Looks like an earless dog looking upward and saying "Boo!".

 

...Whats that mental disease where you see patterns where none exist?

I know everyone is cheering about the Rosetta lander touching down, but they've delayed the next presser, the cold gas thruster failed and the harpoon system didn't fire. It may be in more trouble than they're admitting to.

If you rotate it counter-clockwise 90

That's unfortunate. Hopefully it's not a fatal failure.

 

Is anyone going to watch the Science Channel's Rosetta special that's on tonight at 9 PM EST? I'm looking forward to it, but I'm curious how up to date it's going to be.

Sounds like it bounced and they think it landed again. There was also a signal loss. ESA's updates leave a bit to be desired.

Multiple bounces....

Maybe they'll finally figure out the Sun is generating 'comets'. ;)

LATEST NEWS.

Philae bounced and actually landed twice, nearly bouncing back into space. The ice screws have also not activated and Philae has slipped down a slope but remained upright. Also concern that the solar arrays may not be generating sufficient power, and batteries have a 50 hour charge time without recharging.

Whilst the landing 'worked' it looks like that all is not going well right now.

There will be more news later when Rosetta re-establishes contact with Philae as the Rosetta spacecraft has set from Philae's position.

Philae Lander ?@Philae2014  32m

Hello! An update on life on #67P - Yesterday was exhausting! I actually performed 3 landings,15:33, 17:26 & 17:33 UTC. Stay tuned for more

 

Looks to me like they really need to try and fix that anchoring issue :P But so far it seems like Philae is still on the comit. More news at 13:00UTC today. (Little less that 3 hours from time of posting this!)

Well, compared to something else, *cough*, it actually got into space. 10 years ago or not..

Our Lander's asleep

With its batteries depleted and not enough sunlight available to recharge, Philae has fallen into 'idle mode' for a potentially long silence. In this mode, all instruments and most systems on board are shut down.

"Prior to falling silent, the lander was able to transmit all science data gathered during the First Science Sequence," says DLR's Stephan Ulamec, Lander Manager, who was in the Main Control Room at ESOC tonight.

"This machine performed magnificently under tough conditions, and we can be fully proud of the incredible scientific success Philae has delivered."

Contact was lost at 00:36 UTC / 01:36 CET, not long before the scheduled communication loss that would have happened anyway as Rosetta orbited below the horizon.

From now on, no contact would be possible unless sufficient sunlight falls on the solar panels to generate enough power to wake it up.

The possibility that this may happen was boosted this evening when mission controllers sent commands to rotate the lander's main body, to which the solar panels are fixed. This may have exposed more panel area to sunlight.

The next possible communication slot begins on 15 November at about 10:00 UTC / 11:00 CET. The orbiter will listen for a signal, and will continue doing so when its orbit enables communication visibility in the future.

The hugely successful Rosetta mission will continue, as the spacecraft tracks comet 67P/C-G on its journey to the Sun. Rosetta is the first spacecraft to rendezvous with and orbit a comet and has already returned incredible scientific data.

My mother in law, a rather strict Methodist minister, doesn't see any problem with that shirt at all, and all the people kicking off about it are idiots.  Like in that video above, the only thing she thinks inappropriate is wearing it at a press interview for such an important event, but the shirt itself? Just fine, if a little ugly.
