Less than 200 million km to go. New Horizons is now 199944087 kilometers away from Pluto. http://www.yaohua2000.org/cgi-bin/New%20Horizons.pl |

They could try a hop first, the person who designed the landing gear says it can make the lander hop, if they have power of course. Also it could flip it onto it's back too...... |

Looks to me the main jet is made up of about 14 jets all combining together, awesome. |

... "A straight shot with abrupt braking at Mars takes about six months whereas a trip relying on ballistic capture would take an additional several months" are at odds with one another..." I think they are not considering the insertion burn as part of the cruise. Also of course you have several extra months of cruise time which has to be "manned" back on Earth, which also costs money. Also a longer cruise time could mean more time for a failure to occur. |

...with apparently only two legs in contact with the ground/cliff surface. The SESAME team poster presentation said all three feet were touching the surface, with one leg likely touching the side of the rock or rock face they are leaning against. All 3 sensors recorded MUPUS trying to hammer it's self into the ground, and to do that they have to be touching the ground. |

If I remember correctly such a maneuver was also done with the legs? I am pretty sure the leg raising was not attempted as they decided to use the power needed for that to do science and they did not know fully at the time what the lander orientation was. The body was rotated. |

Quick summary of the French news conference is that Philae has enough power now to keep himself alive, one leg is likely firmly anchored, and the cliff shadow could actually help him operate longer up to and maybe including closest approach to the Sun. |

Yet these aeolian deposits would have to build up the peak of Mt. Sharp while not filling in the moat. Maybe your radial winds would do it. ... were they necessarily a product of standing or running water? There are well known ways of determining if rocks were laid down in running or standing water, the cross bedding. Don't winds curve upwards when entering a depression or crater, becoming weaker at the center, leaving a mound ? |

Do we know if out gassing can cause alterations of the spin axis and rate of spin as the comet approaches perihelion? Possibly : "Evidence is found that the rotation rate of 67P has significantly changed near the time of its 2009 perihelion passage, probably due to sublimation-induced torque." https://hal.archives-ouvertes.fr/hal-01065970 |

This sounds promising : "...As the lander appears to be currently shielded by walls, the local temperature may be lower than it would have been at the chosen landing site. So if Philae wakes up, it might remain operative much longer than expected, possibly until perihelion, which is extremely exciting." http://blogs.esa.int/rosetta/2014/11/19/di...rill-the-comet/ |

Has the surface temperature of a comet been measured as it nears the Sun ?, similar to 67P's orbit ? |

ADMIN EDIT: Unnecessary quoting removed. Please be mindful of rule 3.5 The main Solar Panel lady said it takes 5 or 6 hours to warm the battery up to 0C, so right now the battery won't even be close to being warm enough to be charged up. The hope is as the comet gets closer to the Sun the amount of warming the battery needs will be less. The main reason the lander would have failed would be over heating as the comet gets closer to the Sun, but as we know it's in a shady spot. |

Oh darn it takes 5 or 6 hours of sunlight just to warm the battery up to 0C, so there is pretty much zero chance of any battery power for even transmissions. Until of course the comet heats up. |
