DLR says that Philae get at least 3 hours of sunlight per comet day instead of 1.3 expected. This is nearly 50% of the possible max instead of 20%, right? Not bad at all on this regard.

this morning the CNES director Mr Le Gall reported on France 2 that Philae is fully awake and that a second contact was established, lasting several tens of minutes. It's not clear exactly what the duration of the second contact was - BBC reports that QUOTE The Philae probe made three short contacts of about 10 seconds each at roughly 2130 GMT on Sunday... "We had another contact on Sunday night," explained Paolo Ferri, the head of operations at Esa's mission control in Darmstadt Germany. "...Saturday’s was only 85 seconds; these were 10 seconds in duration spread over several minutes."

But, SD2 wasn't able to sample the surface the first time, correct? IIRC, because of Philae's orientation, it couldn't reach the surface. Is there reason to hope for a different outcome now?
(That said, I'm very pleased to hear Philae's back in action, and hoping for some more images at the very least.) |

I am particularly looking forward to the CONSERT data...

Fredk, you are right - the weight of twitter-evidence today points at seconds, rather than minutes, of connect time. Perhaps he meant the time of the total comm session incl. listening in when he mentioned "minutes".
Anyway, I posted a comment to the Philae awake blog post from ESA, respectfully asking for a daily status update. Even "no news today" would be most welcome to contain my excitement and interest for a next 24 hrs! |

This is a good update, in German, sorry. http://www.dw.de/rosetta-muss-ihre-antenne...hten/a-18518860 |

http://isee3.p3s.nl/philae/ has started displaying new data. So far, it looks like it's just the Rosetta systems (ESS, MSS) with actual data. Looks like real Philae data. According to the ESA Rosetta glossary ESS refers to the Electrical Support System of the lander. It's temperature value was updated 16.06.2015 07:37:30 and shows an increase to 21.43 °C. -------------------- |

From the Rosetta lander user manual:
QUOTE The Electrical Support System (ESS) is part of the overall Lander system, but not mounted within the Lander itself. It is integrated on the ROSETTA Orbiter and provides all interfaces required between the Orbiter and Lander units. QUOTE the Lander Mechanical Support System (MSS)... is also physically installed on the Orbiter

The webmaster at http://isee3.p3s.nl/philae/ confirms that these are old data. Notice the other readings, which relate to pre-delivery status. S/he says: "....I've been meaning to update....."

I would expect science from the surface as early as next week when Rosetta will reach the right "orbit". -------------------- |
