A bit more data has arrived after the connection reestablished. We'll soon see if it drilled comet or empty space I suspect.

Hows it going Philae?

Philae: Fine

Got any data for us?

Philae: I'm just full to the brim with data ...thanks

Great........ er how about beaming it up then?

Philae:......err how about I give it to you via a short USB cable?

Philae?

I'mma put my money on this one: If it finds amino acids, they will be both left and right-handed. If there's an imbalance, it will be very small (~1%).

There might be small precursors of DNA or RNA, as in the nucleobases (no sugars or phosphates attached).

That's about as far as I dare stick my neck out. When will it start giving back data?

I wonder, if there is amino acids , if they have taken Jesus Christ as their personal savior? :coffee:

There's some good news: Rumors are that Philae managed to conduct experiments and gather some chemical data on the composition of the comet before it went into hibernation mode. Analysis of the results are ongoing but there's "carbon-based organics"(is there another kind?) in it.

This is exciting! :whine:

I'd like to see something from an official source though.

and here's my (prose) poem:


Philae

Three hundred million miles from Earth you took a hop, skip and a jump. Which is to say it didn’t work as planned, but you made a valiant effort and did what had never been done. You landed on a comet, even if in the shade. You measured, sniffed and drilled to sample its very being and with your final breath before your batteries died you beamed the results of all you knew to those who were waiting at home.

Indeed; the image gave me the same sense of wonder as I could get (and sometimes still get) when I was a young amateur astronomer and sensed how enormous the universe is.

Looking for Cometary Organics

Before going into hibernation at 01:36 CET on 15 November 2014, the Philae lander was able to conduct some work using power supplied by its primary battery.

With its 10 instruments, the mini laboratory sniffed the atmosphere, drilled, hammered and studied Comet 67P/ Churyumov-Gerasimenko while over 500 million kilometres from Earth. After a triple landing, positioning it in a new, unplanned location, conditions were not optimal, but Philae was able to work for more than 60 hours and send the resulting data back to Earth. It was controlled and monitored from the German Aerospace Center (Deutsches Zentrum fuer Luft- und Raumfahrt; DLR) Lander Control Center (LCC). Now, the complicated data analysis begins.

...

"I'm very confident that Philae will resume contact with us and that we will be able to operate the instruments again," says DLR Lander Project Manager Stephan Ulamec. Once the rechargeable secondary battery has been warmed by sunlight again, Philae will restart and the DLR LCC team will take their places at the control consoles again. "At the first landing site, we would, of course, have had better solar illumination conditions," says Ulamec. "Now we are somewhat in shadow, we will need more time to charge." One advantage of the shadier landing site in a crater is that the Philae lander will not overheat as quickly as the comet approaches the Sun, but will benefit from the stronger sunlight. The team managed to rotate the lander during the night of 14/15 November 2014, so that the largest solar panel is now aligned towards the Sun.

Contact in the coming year

Stephan Ulamec believes it is probable that in the spring of 2015, the DLR LCC will once again communicate with Philae and receive data about how the lander is faring on Comet 67P/Churyumov-Gerasimenko. In the summer of 2015, it might be possible that temperatures on the comet will allow Philae's battery to be recharged. "The orbiter will continue with its overflights to receive any signals from the lander once Philae wakes up from hibernation."

Wakes from hibernation? What are the odds on that? I'll wager a shirt. :doh:

The chances are pretty good that it will pick up sufficient photons to recharge as it nears the sun.

Honestly now, because I likely don't know, but doesn't the entire surface ablate, which would include both Rosetta and the lander? What was the mission expectation on that?
The problem with fantasies is you can't really insist that everyone else believes in yours, the other problem with fantasies is that most believers of fantasies eventually get around to doing exactly that.

IIRC, the reason why the comet was intercepted that far out in the system was because of that very reason. The scientists are fully aware that as the comet nears the Sun, the lander and probe will be lost.
