The first remarkable satellite to have landed on a comet has been successfully sending pictures to the ESA control room but its recent movement has caused serious concerns to the controllers.
Philae was separated from its orbit Rosetta on Wednesday making it the first ever spacecraft to land on a comet. Since then it has been receiving a sufficient amount of sunlight to keep its batteries charged, however a recent change in its movement has resulted in a blockage of sunlight.
Mission controllers are deciding on whether to poke the satellite so as to move it to a sunnier place. Moving has its own repercussions. However it is likely that if Philae remains at its present spot, it may not work after Saturday.
