Placed on the comet, Philae will study the structure

During this part of the mission, the spacecraft will be fully dedicated to the lander and put in the best possible configuration for the help.

Note that initially, the module will run on non-rechargeable battery. It is very difficult to "determine its life, it can work up to five days after it started". Will be taken over by the solar panels that recharge a battery low power. This will allow the lander run long, with one instrument at a time. From that moment, Rosetta is no longer in support of Philae. He will be working around its own objectives and communicate with the probe, during phases of sight between the two devices. Essentially, it will download data to relay to Earth.

Placed on the comet, Philae will study the structure

Of the 13 scientific instruments on board include a drill provided by the Italians. It can dig up to 250 mm below the surface of the comet and will charge two successive samples sent to three instruments. This will make it possible to analyze and highlight all the molecules that escape from the comet. These are rapidly photodissociated by the rays UV of the sun, we do not see, from Earth, the molecules daughter. Philae will also he (finally) to see the nature of the parent molecules. Another eagerly awaited and interesting development: the question of the origin of water on Earth .
