On November 12, a spacecraft named Philae made a landing on the comet 67P/Churyumov-Gerasimenko. This made Philae the first spacecraft to ever land on a comet. Philae is the European Space Agency’s robot lander and it traveled with its mothership Rosetta for 10 years before reaching the comet in August this year. Rosetta and Philae orbited the comet and figured out a good landing spot on it before Philae made the trip down to the comet’s surface. Philae is going to be studying the composition of the comet. Both Rosetta and Philae are unmanned. Scientist believe comets contain materials left over from when our sun and its planets initially formed. They are like time capsules that might tell us more about the origins of Earth as well. A comet is a large ball of frozen gases, rock, and dust that orbits our sun. Here is a video about Philae’s landing.
