La I-Arhente YaseYurophu Yendawo (ESA) iphumelele into engaqhelekanga: ukuphucula kakhulu ukubalwa kwe-orbit ye-interstellar comet 3I/ATLAS Enkosi kumbono "wangaphandle" ovela kwi-Mars orbit. I-orbiter I-ExoMars Trace Gas Orbiter (TGO) yongeze imbono yesibini kuleyo yeendawo zokujonga eMhlabeni, ivumela umkhondo wayo ukuba uhlengahlengiswe ngokuchanekileyo ngakumbi.
Ngokutsho kwamaqela e-arhente, isisombululo esitsha se-orbital sinciphisa ukungaqiniseki ngento ethile ishumiOlu lungiso luza ngexesha elifanelekileyo: i-comet ihamba ngeSolar System ngesantya esiphezulu kwaye, nangona aluyongozi, ikhutshwe nge I-ephemeris Uphando oluchanekileyo luququzelela zombini isayensi kunye novavanyo ukhuselo lweplanethi.
Umbono omtsha ovela kuMars uphucula ukubala
Kuze kube ngoSeptemba, isikhundla se 3I/ATLAS Inokuqinisekiswa kuphela ngeeteleskopu ezisekelwe emhlabeni. Phakathi kwe Ngo-Oktobha 1 kunye ne-7I-TGO itshintshe umdlalo: yabona i-comet evela umjikelo weMartian, kanye njengoko idlule ngokusondeleyo kwiplanethi ebomvu, kunye nendlela encinci yokujikeleza Iikhilomitha ezingama-30 ezigidi Nge-3 ka-Okthobha.
Ngaloo geometry, i-ESA yakwazi ukudibanisa imilinganiselo "evela ekhaya" (Earth) kunye ne-angle eyongezelelweyo evela kuMars kwaye yenza Unxantathu Inamandla kakhulu. Isiphumo esithe ngqo yaba kukutsiba okucacileyo kumgangatho we [engacacanga], isitshixo senkqubo. imigqaliselo elandelayo kwaye baqonde ngcono iintshukumo zondwendwe oluvulelekileyo.
Iqela ligxininisa ukuba umphumo ugqithise ulindelo: ukuphuculwa okuthobekileyo kwakulindelwe, kodwa ukuncitshiswa kwempazamo kuzuze uphuculo olubonakalayo. x10Ekubeni i-comet ihamba ngesantya ngokomyalelo we amakhulu amawaka eekhilomitha/hIkhilomitha nganye efunyenwe ngokuchaneka ibala ukuya kumlinganiselo we-coma, imisila kunye nomsebenzi emva kweperihelion.
Ukusuka kwi-CaSSIS ukuya kwi-ephemeris: le yindlela eyacocwa ngayo i-orbit
Isixhobo ICASSISIdizayinelwe ukwenza imephu yomhlaba weMartian ngesisombululo esiphezulu, yayisetyenziswe ngendlela engaqhelekanga: yayibhekiselwe esibhakabhakeni ukuze ibambe. 3I/ATLAS ngokuchasene nemvelaphi eneenkwenkwezi. Olo buchule lwalufuna ukuqwalaselwa ngenyameko indawo ngqo ye-orbiter, ejikeleza ngokukhawuleza ijikeleze i-Mars, into edla ngokungafunekiyo kuqwalaselo olusuka kwizibonelelo ezisisigxina eMhlabeni.
Ubunzima bezobugcisa bebufanelekile. Imilinganiselo yesiphumo yayichanekile ngokwaneleyo ukuba i Iziko lePlanethi encinci (MPC) —uvimba wezizwe ngezizwe we<em>astrometry ye<em>comet nee<em>asteroids — yamkelwa okokuqala imigqaliselo esemthethweni evela enqanaweni kumjikelezo ojikeleze enye iplanethi. Asiyombali nje yenzululwazi; ikwavula ucango kwiiprothokholi zokusebenza ezinokuphindwa kunye nezinye izinto ezinqabileyo.
Ukudibanisa idatha ye-CaSSIS neenkcukacha ezivela kumaziko ophononongo asekelwe emhlabeni kufuneka amaqela alungelelanisiweyo i-flight dynamicsIzixhobo kunye nohlalutyo lwenzululwazi. Lo msebenzi odibeneyo wenze ukuba kube lula ukulinganisa i-trajectory ye-comet kunye "nengxolo" encinci kwaye unikeze i-ephemerides ethembekileyo kuluntu lokujonga.
Uvavanyo oluluncedo lokukhusela iplanethi
Kulo mongo, i-ESA ibonisa ukuba ukudibanisa amaqonga eeplanethi Ukusebenzisa iiteleskopu ezisekelwe emhlabeni kunokwenza umahluko omkhulu. Ukuba kukhe kufuneke, ukuseta okufanayo kunokuvumela ukunyanzeliswa kwe-orbit ekhawulezayo nangaphambili, ukuphucula imida yesilumkiso kwangethuba kwiimeko ezahlukeneyo. ukhuselo lweplanethi.
Yintoni elandelayo: JUICE, NeoMIR, kunye neComet Interceptor
Emva kokudlula kwi-perihelion ekupheleni kuka-Okthobha, i-comet yabonwa yi-European probe IJUZI ngoNovemba, ngexesha lomsebenzi ophezulu. Idatha yenzululwazi kulindeleke ukuba ifumaneke ukusuka kwangoko ngo-2026, eya kubonelela ngomxholo womzimba kwi-trajectory esele ilungisiwe.
Ukujonga phambili kancinci, iYurophu ilungiselela amandla athile: NeoMIR Iya kubeka iliso "indawo eyimfama" eyenza ukukhanya kwelanga kubonwe emhlabeni, kunye I-Comet Interceptor Yenzelwe ukuthintela i-comet efundwe kancinci-kunye nokwenzeka ukuba inokuba nayo phakathi kweenkwenkweziZombini ezi mishini zomeleza indlela yaseYurophu apho isayensi kunye nokulungela kusebenza kunye.
Ngawo wonke lo msebenzi, i-ESA ibonise ukuba jonga ukusuka kuMars Ayisiyonto nje yobugcisa, kodwa sisixhobo esisebenzayo: indlela esebenzayo yokukhomba i-orbit ye-comet yangaphandle kunye nokuvavanya, kubomi bokwenyani, ukuba i-interplanetary sky-monitoring network kufuneka isebenze njani.
