<prompt> Fingqa isihloko: Umkhumbi-mkhathi iRosetta ka-Esa ulungiselela ukudlula okunobuhlakani phakathi kwama-geyser e-comet 67PChuryumov-Gerasimenko. Ososayensi banethemba lokuthola ukwaziswa okwengeziwe mayelana nengaphakathi lezinkanyezi ezinomsila kusukela kumajethi. Futhi njengoba le nkomishi iba nomdlandla ngokwengeziwe njengoba isondela elangeni, lezi zinyanga ezimbalwa ezizayo zinikeza ithuba elihle kunawo wonke okwamanje lokuyifunda - kodwa akuyona into engenangozi. I - ESA ilungiselela ukuthumela indiza yayo yezindiza i - Rosetta endaweni engamakhilomitha angu - 9 ukusuka ku - 67P. Lo mshini uzothunywa ukuba ufunde amajethi avela ebusweni bayo okuboniswe esithombeni. Lokhu kungembula ukuthi ingaphakathi le - comet lakhiwe ngani. Futhi njengoba i-comet iba nomsebenzi owengeziwe, i-Philae engaphezulu ingavuka. I-comet iya ngokuya ithakazelisa kakhulu, kusho usosayensi wephrojekthi ye-Rosetta yakwa-Esa uDkt Matt Taylor kuThe Times. Amakhulu amakhilogremu ngomzuzwana wezinto ezibonakalayo ayaphonseka kuwo. Sifuna ukudlula ngesinye salezi zindawo ezisebenzayo. 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 67P Churyumov-Gerasimenko 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-3.3ft imitha elilodwa 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. I-Philae yakwazi ukufeza amaphesenti angaphezu kuka-90 emigomo yayo ngaphambi kokuba iphele amandla. Phakathi naleso sikhathi, iRosetta iyaqhubeka izungeza futhi ifunda le nkomishi. Ngokwemininingwane eqoqwe yilezi zivivinyo ezimbili, u - Esa wathi amanzi akulesi siqhumane ayehlukile kwawasemhlabeni - okusikisela ukuthi amanzi asemhlabeni wethu avela kuyi - asteroid, hhayi esiqhumane. Umshini wokuhlola uyo...  <response>: I - ESA izothumela indiza yayo yezindiza i - Rosetta endaweni engamakhilomitha angu - 9 ukusuka ku - 67P. Umthwalo womsebenzi wale probe kuzoba ukutadisha amajethi avela ebusweni bayo. Lokhu kungembula ukuthi ingaphakathi le-comet lakhiwe ngani. Futhi njengoba i-comet iba nomsebenzi owengeziwe, i-Philae engaphezulu ingavuka.
