QUOTE (elakdawalla @ Nov 14 2014, 04:26 PM)  Well spotted. I didn't notice that. now I wonder if bright spot is Philae and dark spot its shadow. if you draw a straight line thru those two points, where does it cross the blue diamond? |

SIGNAL IS BACK telemetry & science data are flowing from the surface !

You shouldn't assume that a ballistic trajectory would be seen as a straight groundtrack as seen from Rosetta's vantage point.

QUOTE (polaris @ Nov 15 2014, 12:37 AM) Science from an alien world: COSAC instrument data now flowing from Philae. That's really good news! So there is still battery power, and we've a chance to see compositional data. |

Rotation command sent gear up -- this pass is 3-4 hours of com time...last best chance for continued life...
now all we have to do is wait... |

So are they actually attempting to dislodge it from the side of the cliff? In other words "push" it out farther "away" from the cliff into a flat area? or are they just rotating the main body on the legs?

From ESA operations:
Lander now performing 'lift & turn' of the main body on the landing gear - will last about 10 mins. telecomm link is good ESA OPS |

35 degree rotation achieved... no idea on power state yet - someone said better is good - but no idea for how much longer - have to hope one of the bigger panels is now oriented...

Emily's tweets are gripping news. I haven't been this much on edge since watching Europa Report (another Last Comm Chance type story!). Visit https://twitter.com/elakdawalla -- the updates will appear without refreshing the page.
