Lander manager says Philae is doing well but battery life is low

The European Space Agency’s Rosetta mission will end Sept. 30 with a dicey descent to the core of comet 67P/Churyumov-Gerasimenko, a risky, but potentially rewarding finale punctuated by commands to automatically safe the probe’s rocket thrusters and turn off its radio transmitter.

Rosetta flight director Andrea Accomazzo says the Philae lander is ready for a daring descent and touchdown Wednesday on comet 67P/Churyumov-Gerasimenko. The European craft is making the world’s first attempt to land on a comet.

Just before settling to a soft crash landing Friday, the European Space Agency’s Rosetta spacecraft captured close-range images of comet 67P/Churyumov-Gerasimenko, peering into a stadium-sized pit and recording a final dataset to keep scientists busy long after the mission’s end.
