The Philae Lander is a robotic spacecraft that was part of the European Space Agency's Rosetta mission. Launched in 2004, it successfully landed on the comet 67P/Churyumov-Gerasimenko in November 2014. Philae's primary goal was to study the comet's surface and gather data about its composition. After landing, Philae conducted various scientific experiments, including analyzing the comet's organic molecules. However, it experienced a bumpy landing and ended up in a shadowed area, limiting its solar power. Despite these challenges, Philae transmitted valuable information back to Earth before its batteries ran out in 2015.
