I'm glad for the dust bite.. I'm sad that we don't know what flavor. ...it was exciting while it lasted

I understand that the batteries have got weak due to "bad parking".

Does anyone know how long the batteries can survive in a discharged state?

Will it "come back" to the solar system in that time scale, or are we talking about a really long time?

Landing on a sphere is easier than landing on a giant cashew. Given the circumstances, Philae did remarkably well. If not 100% successful, how about 80-90%?

An incredible feat of navigation. It provided more data then expected. A job well done.

congrats to the ESA .

Bruce Willis, Billy Bob Thornton and Ben Affleck showed NASA how to do this in 1998 on the Armageddon mission.

Armageddon? Yes, Armageddon outa here now!

Next time ESA sends something into space maybe they'll include ENOUGH quarters for it to "call home" for longer than just 90 days!

That is why it could not call home, they issued Euros and they don't work unless in EU zones and I don't believe space is a EU member.

This is the second 'death' of Philae. The first was when they tried to 'shift it's landing spot' and caused it to topple over into a shadowy crater. We thought it was gone for good and counted as good luck that we landed at all, and got some good data that might help future missions.

... Then, like the Monty Python sketch we heard a weak voice, "...I'm not dead yet." The comet had moved further in its orbit, and that crater was getting enough sun for what was left of the lander's solar panels to harvest. Now it has gone quiet again, due to lack of power. We mourn its passing, and celebrate it's life and the data it has provided.

... But someone should stay by the radio, in case Philae isn't done with the sketch. The 'Not Dead Yet' man had a few lined contesting his supposed demise. We should wait until we're certain we won't hear that faint cry of "...I feel happy! (cough)" before we call up Mr. Cleese for the Dead Parrot Lander sketch.

I checked on the Comet and it looks like we might "see" Philae again:-

......is a comet, originally from the Kuiper belt, with a current orbital period of 6.45 years, a rotation period of approximately 12.4 hours and a maximum velocity of 135,000 km/h (38 km/s; 84,000 mph). Churyumov-Gerasimenko is approximately 4.3 by 4.1 km (2.7 by 2.5 mi) at its longest and widest dimensions. It was first observed on photographic plates in 1969 by Soviet astronomers Klim Ivanovych Churyumov and Svetlana Ivanovna Gerasimenko, after whom it is named. It came to perihelion (closest approach to the Sun) on 13 August 2015.
