Time is running out for the comet lander Philae, which has been in hibernation since July 9 last year.<br />For scientists, every moment without contact with the sleeping space probe means coming closer to losing it completely.<br />This is why the European Space Agency (ESA) is doing all its best to wake up the long-silent comet lander.<br />European scientists will transmit a signal into space on Sunday, Jan. 10, to try to nudge Philae back to life and hopefully restore contact.<br />ESA and DLR experts said there are several possibilities as to what Philae's condition on the comet is.<br />Philae may just be too dusty to power on, so the DLR team plans to take advantage of Philae's momentum wheel called "flywheel" and command it to spin.<br />The flywheel is a device that stabilized the comet lander's descent to comet 67P/Churyumov-Gerasimenko.
