On September 5, the Rosetta spacecraft detected its lost lander Philae, wedged in a dark corner of comet 67P-Churyumov-Gerasimenko, according to European Space Agency reports. Since then, Rosetta, apart from itself observing the comet, has made several excursions to try and see if Philae would wake up and become operable. The International Rosetta Mission was approved in November 1993, and it took nearly a decade for the launch (in March, 2004). On reaching the comet, Rosetta planted Philae on it for close observation. Now, as calculated on September 2, Rosetta is 676,344,049 kilometres from the earth and moving further every minute, accompanying its comet.
