The world will be holding its collective breath as this washing machine sized
lander attempts to do what has never been done before – safely land on a comet.
If successful, and this landing is by no means assured of success due to the
hazardous conditions that will be encountered, Philae will conduct at least
several days of science observations. The lander will photograph, sample and dig
into the surface of the comet to analyze pristine cometary material.
The world should know if the landing was successful at 11:02 a.m. EDT as that is
when the touchdown signal will be received at Earth. That will be seven hours
after detaching from the Rosetta orbiter.
