<prompt> Fingqa isihloko: Umkhumbi-mkhathi we-Philae olahlekile owawela phezu kwenkanyezi enomsila eqhele ngamakhilomitha ayizigidi ezingu-284 ukusuka eMhlabeni ungase uvuke namuhla. Ososayensi e-European Space Agency baye baqala kabusha imizamo yokulalela isignali evela esikhaleni sokufika esishayekile ku-comet 67pChuryumov-Gerasimenko. Balahlekelwe ukuxhumana nesiphuphutheki esikhulu njengomshini wokuwasha ngo-November wonyaka odlule ngemva kokuba siqhume izikhathi eziningana ngaphambi kokuba siwele emgodini ngaphansi kwewa. Njengoba yayingenakho ukukhanya kwelanga eyayikudinga ukuze inikeze amandla ucwaningo lwayo, amabhethri omshini wokwehla aphela ngemva kwamahora angaba ngu-60 kuphela isendaweni. Ososayensi be-ESA bavuselele imizamo yabo yokuxhumana ne-Philae lander ku-Comet 67p, ekhonjiswe emfanekisweni ongenhla. Nokho, njengoba le nkanyezi enomsila isondele kakhulu elangeni ohambweni lwayo oludlula ohlelweni lwelanga, abacwaningi banethemba lokuthi i - Philae izothola ukukhanya okwanele ukuze ivuseleleke. Umkhumbi-mkhathi i-Rosetta, owawuthwele i-Philae, wathunyelwa emkhathini ngo-2004, esebenzisa amandla adonsela phansi oMhlaba noMars ukuze ufinyelele ku-comet 67P. Lalijaha i-comet 67PChuryumovGerasimenko emkhathini iminyaka engaphezu kweyishumi, futhi langena emzileni ngo-Agasti 2014. Ngemuva kohambo lwamamayela ayizigidi eziyizinkulungwane ezine 6.5 billion km, uphenyo lwabe selukhulula ngempumelelo i-Philae lander ekubambeni kwayo ukuyohlala ku-comet ngoNovemba 12, 2014, luhamba nge-1 imitha 40 amayintshi ngomzuzwana uma kuqhathaniswa ne-comet. Kodwa lapho iqala ukuxhumana nenkabazwe yehluleka ukudubula ama-harpoon ayengayigcina inamathele kuyi-comet. Lokhu kwabangela ukuba liphakame ngamamayela angu - 0,62 1 km ngaphezu kwenkanyezi enomsila ngaphambi kokuba liphinde liwele phezu kwalo. Yabe isibuyela emuva, kodwa yabe isishaya phansi kakhulu. Ososayensi muva nje baye bathi amanzi akulesi siqhumane ayehlukile kulawo asemhlabeni - okusikisela ukuthi amanzi asemhlabeni wethu avela kuyi - asteroid, hhayi esiqhumane. I - European Space Agency manje isiyivule iyunithi yezokuxhumana emkhunjini wesikhala i - Rosetta ozungeza i - comet. UStephen Ulamec, imenenja yephrojekthi ye-lander e-German Aerospace Centre DLR, wathi: Njengamanje i-Philae ithola cishe amandla elanga aphindwe kabili...  <response>: I-European Space Agency isiqalile ukuzama ukuxhumana nesithwebuli esilahlekile. I - Philae ibilokhu ingekho kusukela ngo - November lapho ifika ku - Comet 67p. Ososayensi bakholelwa ukuthi i-lander yagxumela emseleni emthunzini wegquma. Kodwa bathi kungenzeka ukuthi seyiphapheme kakade kodwa ingakakwazi ukuthumela imiyalezo. Umkhumbi-mkhathi udinga amandla angu-19 W kusuka kumapaneli awo elanga ukuze uxhumane. Njengoba i-comet isondela elangeni isitshalo sokwehla singathola ukukhanya kwelanga okwengeziwe. Ososayensi bathumele imiyalo kuPhilae ukuze iqale ukuzifudumeza. Bazozama ukuxhumana ne-lander ngeRosetta ezinsukwini ezingu-8 ezizayo.
