Isu tinoziva kuti Saturn ine masatellite akawanda. Yekutanga uye iyo huru inozivikanwa nezita rekuti Titan. Iyo satellite yakanyatso dzidza ine maitiro akasiyana kubva kune mamwe ese emwedzi weSaturn. Zvimwe chetezvo zvinoitika nemamwe masatellite emamwe mapuraneti. Izvi zvakasiyana nezvimwe zvakaita kuti masayendisiti ade kuziva.
Naizvozvo, isu tichakumikidza chinyorwa ichi kuti tikuudze nezve hunhu hweTitan, kuwanikwa kwayo, mhepo uye zvimwe zvakawanda.
Mhando huru
Titan ndiyo yechipiri yakakura setiraiti mune solar system, mushure meGanymede, inotenderera Jupiter. Uyezve, Titan ndiyo yega satellite mune yedu solar system ine dense mhepo.. Mhepo iyi inoumbwa zvakanyanya nenitrogen, asi ine methane nemamwe magasi. Nekuda kwekuumbwa uku, nzvimbo yeTitan yakafukidzwa nemadziva nemakungwa emvura methane uye ethane, kwete mvura yemvura sePasi.
Musetiraiti iyi tinowanawo makomo, madunduru ejecha nenzizi, kunyangwe panzvimbo pemvura, nzizi idzi dzakaumbwa nezvinwiwa zvehydrocarbon. Uyezve, Nzvimbo yeTitan inogara ichichinja nekuda kwekuita kwe geological uye kukanganisa kwemhepo.
Chimwe chinhu chinonakidza cheTitan ndechekuti ine methane kutenderera kwakafanana nekutenderera kwemvura paNyika. PaNyika, mvura inoputika kubva mumakungwa, yoita makore, yobva yanaya semvura pamusoro. Pane iyi setiraiti, methane inobuda mumadziva nemakungwa, youmba makore, yobva yanaya semvura pamusoro.
Masayendisiti anotenda kuti Titan inogona kuve nekugona kutsigira hupenyu, kunyangwe zvisiri sezvatinoziva paPasi nekuda kwemamiriro akanyanya ezvakatipoteredza. Iyo NASA Cassini-Huygens mission yakadzidza Titan kweanopfuura makore gumi uye yakawana ruzivo rwakawanda nezve satellite iyi.
Titan kuwanikwa
Mugore ra1655 muongorori wenyeredzi wechiDutch Christiaan Huygens, achishandisa teresikopu yake, akawana chinhu chinotenderera Saturn. Pakutanga, akanga asina chokwadi kuti chaiva chii, asi mushure mekucherechedza kakawanda akagumisa kuti yaiva satellite. Huygens akatumidza setiraiti "Titan" mushure mehofori kubva mungano yechiGiriki aive mwanakomana waGaea naUranus. Muchokwadi, Huygens akawanawo mamwe matatu masatellite eSaturn, asi Titan yaive yakakura uye inonakidza.
Mumakore akatevera, kucherechedzwa kwakawanda kwesetiraiti kwakaitwa, asi nekuda kwekusakwana kweteresikopu yenguva iyoyo, hapana ruzivo rwakawanda rwaigona kuwanikwa. Yakanga isiri kusvika pakuuya kwezera remuchadenga, muma1970, apo NASA yakatumira mission yeVoyager 1 kuti iongorore hurongwa hweSaturn.
Basa reVoyager 1 rakapa mifananidzo yekutanga yemhando yepamusoro yeTitan, ichibvumira masayendisiti kuti adzidze mamiriro esatellite uye pamusoro pezvakadzama. Asi yaive mishoni yeCassini-Huygens, yakatangwa muna 1997 uye kusvika kuSaturn muna 2004, iyo yakatipa maonero akazara eTitan.
Iyo Huygens probe yakamhara pamusoro peTitan pamusoro pe2005 uye ndicho chaiva chitundumuseremusere chekutanga kumhara pasetiraiti kunze kweMwedzi. Basa reCassini-Huygens rakapa hupfumi hwe data uye rakashandura kunzwisisa kwedu kweTitan. Kutenda kune tekinoroji, zvave zvichibvira kudzidza zvakawanda nezvechinhu chakawanikwa makore anopfuura 300 apfuura.
Titan mamiriro
Zvakakosha kutaura kuti mhepo yeTitan yakaoma zvikuru kupfuura yePasi. Kutaura zvazviri, ine mhepo yemuchadenga iri pamusoro inodarika zvakapetwa kaviri pane yePasi. Zvakare, kusiyana nePasi, mhepo yeTitan inogadzirwa zvakanyanya nenitrogen, ne98,4% yehuwandu hwayo.
Chinoita kuti mhepo yesatellite iyi iwedzere kunakidza ndechekuti inewo methane, ethane nemamwe magasi, zvichiita kuti ive yakasiyana musolar system yese. Pamusoro pazvo, kuvapo kwemagasi aya kwakakonzera kuumbwa kwemhute mumhepo yeTitan, ndosaka zvichinetsa kuona nzvimbo yayo nemateresikopu.
Nekuda kwekuvapo kwemethane, kune mamiriro ekunze akafanana neaya ari paNyika. Ndiko kuti, kune kufefeterwa kwemethane kubva kumadziva epamusoro nemakungwa, kuumbwa kwemakore, kunaya kwemvura, uye kuiswa kwepamusoro. Muchokwadi, nzizi nemadziva anowanikwa pamusoro peTitan anofungidzirwa kuve akagadzirwa nemvura methane.
Masayendisiti akaonawo kuchinja kwemwaka mumhepo yeTitan, sekuumbwa kwemakore echando pamatanda munguva yechando uye kuoneka kwemadutu mumhepo munguva yezhizha.
Misiyano neplanet Earth
Chokutanga pane zvose, zvinofanira kutaurwa kuti Titan is satellite, nepo Earth ipuraneti. Izvi zvinoreva kuti Titan haina mhepo inokodzera hupenyu sezvatinoiziva. Zvakare, nekuti Titan inotonhora zvakanyanya kupfuura Earth, pamusoro payo pakafukidzwa nemethane uye ethane ice panzvimbo pemvura.
Mumwe musiyano mukuru ndewekuti satellite haina magineti zvinoreva kuti haina kudzivirirwa kubva kune chaji particles dzinobva kuZuva.Izvi zvinoita kuti mwaranzi wepaTitan ukwire zvakanyanya kudarika wePasi. Zvakare, simba rinokwevera zvinhu pasi rakadzikira zvakanyanya pane rePasi. Dai taiva paTitan, taigona kusvetuka zvakanyanya kupfuura pasi redu.
Chekupedzisira, mumwe musiyano mukuru ndewekuti tembiricha iri pasatellite inotonhora zvakanyanya pane yePasi. Avhareji tembiricha pamusoro pamusoro satellite anenge -180 madhigirii celsius, nepo avhareji tembiricha pamusoro pePasi penyika ari kumativi 15 madhigirii. Izvi zvinoreva kuti chero hupenyu hwaigona kuvepo paTitan hwaizofanira kujairana nemamiriro akanyanya kunyanyisa kupfuura epaPasi.
Ndinovimba kuti neruzivo urwu unogona kudzidza zvakawanda nezve Titan satellite uye maitiro ayo.
