Re "I had dinner tonight with a member of the Rosetta mission.":
Male or female? I hope you dressed appropriately - they are easily moved to
tears those scientists.
Scientists "easily moved to tears?" I think not. That's more the province of
those who have allowed their emotions to delude them into believing that the
world around them was designed rather than just evolved. :-)
The scientist is male, and quite smart BTW. The Rosetta mission only accounts
for about a quarter of his workload, the rest of his time being spent on
something potentially far more valuable. He's in charge of maintaining the
database tracking all asteroids, meteors, comets, etc. that could potentially
hit the Earth. The size of it gives new meaning to "Terra-bytes" of data. :-)

just sleeping, not dead. In Monty Python terms, it is not an ex-lander. It's
merely "pinin' for the fjords..." :-)

Yes, I agree. Quite an accomplishment. This was a shorter mission, but
extremely exacting. The Cassini mission to Saturn, another undertaking of
similar difficulty, took 30 years from conception to getting the spacecraft to
Saturn, and they also landed a package on Saturn's moon Titan, taking images on
the way down. Cassini has been orbiting Saturn for 10 years, so from drawing
board to today, the mission has taken 40 years out of some people's lives.
Think of it you are a 20-year engineer at the start of the mission, and now you
are 60!

Using that information it is possible to extrapolate a more visually appealing
version of the data that may look more like it actually would to the human
eyes. The movie below runs a speeded up version of the descent, approximately 2
minutes go by every second. The rocks on the ground at the end are made of
water ice. The temperature on Titan's surface is about -180 degrees C., so
rocks of ice are very hard.

Xeno,
The scientists are happy that they have accomplished a very intricate
technological feat by keeping the mission on course for 10 years and then
landing a probe on the comet itself.
It would been a great bonus if they could keep the lander alive for a few
months to make more scientific observations.

ESA scientists have stated that Philae may wake up again, when its batteries
are recharged by the sun, to do more work in the near future.

The Philae lander has detected organic molecules on the surface of its comet,

instrument designed to "sniff" the comet's thin atmosphere.OK - so organic
molecules aren't life as we know it, but they were found on a measly comet.
Pity we've lost the phone connection - just when the conversation was getting
interesting.
