Philae (/ˈfli/[3] or /ˈfl/)[4] is a robotic European Space Agency launder that accompanied the Rosetta spacecraft[5] till its designatit laundin on Comet 67P/Churyumov–Gerasimenko (67P), mair nor ten years efter departin Yird.[6][7][8] On 12 November 2014, the launder achieved the first-ever controlled touchdoun on a comet nucleus.[9][10] Its instruments obtained the first images frae a comet's surface an are expectit tae mak the first in situ analysis tae determine its composeetion.[11] Philae is tracked an operatit frae the European Space Operations Centre (ESOC) at Darmstadt, Germany.[12]
