The Rosetta was launched by the European Space Agency on March 2, 2004. Philey was the lander in it.
Rosetta’s target is “67P / Churyumov – Gerasimenko”, a comet located 405 million kilometers from Earth. 67P / Churyumov – Gerasimenko, located in the Kuiper Belt, is a comet about 4 km in diameter.
Between 1978 and 2005, there were 20 comet landing missions in various countries. Of those, 5 missions were a complete failure. Of the remaining 15 missions, the Rosetta mission landed in a lander comet.
Launched on 2 March 2004, the Rosetta spacecraft launched the lander 67P Comet on August 6, 2014, after a 10 – year journey.
Phile Lander’s mission was to explore for 5 months. But Filey was unable to land accurately at the pre-determined landing spot. The problem was the lack of gravity. Eventually it landed in a place where there was not enough sunlight. So Filey’s solar panel stopped working. Filey’s mission, which was planned for 5 months, was reduced to 60 hours. But in those 60 hours, Filey was able to gather as much information as possible and send it to Rosetta.
