The good news is that the Philae lander is awake for a few hours each day and is talkative. The bad news is that it is hard for the Rosetta orbiter to link with it.
The first contact with Philae since its seven month hibernation ended was on June 13. Confirmed contacts were made on June 14, 19, 20, 21, 23 and 24 but all have been too short to allow transfer of the data the lander has stored. There are two large blocks of data in storage, and each will take about 20 minutes to upload to Rosetta. The June 24 link did last 20 minutes, but was so intermittent that only 80 packets were received.
The dilemma is that Rosetta needs to be closer to the comet to communicate with Philae. But the comet, nearing perihelion (the closest it comes to the sun) is warming up and creating its coma of dust. In April, the dust confused Rosetta's navigational system, which needs to pick out bright stars but could not distinguish them from dust grains, and Rosetta went into safe mode, which shut down science operations. So the orbiter was moved away from the comet to protect it from the dust. But now that is making it hard to talk to the lander.
Moving Rosetta closer to the comet would improve communication with the lander, but would put Rosetta -- and hence the entire mission -- in jeopardy. When the lander was deployed, Rosetta was in a trajectory that flew between comet latitudes +15º and +25º. Rosetta's trajectory has been shifted to carry it over lower latitudes (-8º), which improved the signal, and is now gradually being moved northwards again, to find the optimum latitude for communication.
The ultimate hope, of course, is not only to retrieve the two blocks of data the lander has stored, but also to be able to carry out more lander operations, including sampling the comet's surface with the drill and analyzing it chemically. Comets are expected to be rich in complex organic compounds, and astrobiologists are eager to know exactly what is there. E.g., are there amino acids? If there are, are they racemic mixtures or is one enantiomer more abundant than the other?
