I (am) was on-site at ESA's European Space Operations Center (ESOC) in Darmstadt for the Philae landing on comet 67P/Churyumov-Gerasimenko
This blog-post will be live updated as the events unfold.
Be sure to hit refresh upon a new visit!I will also be tweeting through @Marco_Langbroek)
15:10 Brief recap of the Google+ briefing of this afternoon: Matt Taylor apologizes for #shirtgate. Contacts Rosetta-Philae are very stable. 80% of the most important science data from the first science sequence are now in. Rosetta has not imaged Philae on the surface yet, but there are still images in the pipeline and the search continues. Holger Sierks suggests that in fact, they should have caught the lander just before touchdown at 500 meter above the surface, and during the first bounce in the images from the first two hours after touchdown, which have not been downloaded yet. These images should give the direction of the rebounce.
Lomatsch told that Philae has not moved at all since finally settling. Philae is in a difficult position however, surrounded by walls, limiting sunlight reaching the solar panels.From what she said, I get the impression that hopes for a lander revival once 67P/ is closer to the sun, should not be too high.
During the Q&A Ulamec indicated that it is unlikely that cometary jets will blow the lander from the surface as activity increases, as it has a too high density.
The DS2 drill is already extended 25 cm below base plate, but as there is a (scheduled) loss of contact right now, it is unsure whether it can/has reached the surface yet. New (and perhaps last) contact with Philae near 22 CET this evening. A command to go into low power mode did however not reach Philae, so it is going to get really close wether the next contact will be successful.
11 Nov - The go/no go decision of this evening has given a 'go' as verdict. Early tomorrow morning there will be a second, and last, go/no go moment.
