Mars adakhalako kale, ndiye chinachitika ndi chiyani?

Kodi moyo unayamba pa Mars kenako nkupita ku Earth kuti ufalikire? Zaka zingapo zapitazo, chiphunzitso chotsutsana kwanthawi yayitali chotchedwa "panspermia" chidakhala ndi moyo watsopano, popeza asayansi awiri mosiyana adati dziko lapansi loyambirira lilibe mankhwala ofunikira pakupanga moyo, pomwe koyambirira kwa Mars kuyenera kuti anali nawo. Chifukwa chake, chowonadi ndichani kumbuyo kwa moyo waku Mars?

Pambuyo pophunzira Mars kwazaka zambiri, asayansi amavomereza kuti pali kuthekera kuti asteroid kapena comet zimasintha zomwe Red Planet idachita. Poyerekeza ndi Dziko Lapansi, Mars ili ndi ma crater ambiri, zomwe sizosadabwitsa chifukwa malo a Mars pamalo athu ozungulira dzuwa, pafupi ndi lamba wa asteroid.

Zotsatira zake, Mars akupitilizabe kupondereza ma asteroid, ndipo mosiyana ndi Dziko Lapansi, Mars ilibe mwezi wokulirapo kuti uteteze ma asteroid omwe akubwera.

Tikayang'ana m'mbuyo kupyola nthawi, tikudziwa kuti miyala yayikulu yamlengalenga idakhudza Dziko Lapansi m'mbuyomu, ndipo zina mwazimenezo mwina zidasintha mbiri ya dziko lathuli.

Ma cenotes ambiri (sinkholes) omwe amakhala mozungulira chigwa cha crater akuwonetsa chimbudzi cham'mbuyomu chazovuta zomwe zidakhudzidwa. © Chithunzi Pazithunzi: Wikimedia Commons

Chigwa cha Chicxulub, chomwe chili pachilumba cha Yucatan ku Mexico (onani chithunzi pamwambapa), ndi chimodzi mwazitsanzo zabwino kwambiri zomwe timazidziwa, ndipo akatswiri ena amakhulupirira kuti ndicho chomwe chimayambitsa kutayika kwa dinosaur.

Kodi ndizotheka kuti zoterezi zitha kuchitika ku Mars ngati zoterezi zichitike Padziko Lapansi? Ku Mars, tidapeza chiphalaphala chosangalatsa m'dera la Lyot chomwe chili pafupifupi ma kilomita 125 m'mimba mwake.

Lyot ndi mphonje yayikulu kwambiri m'chigawo cha Vastitas Borealis ku Mars, yomwe ili pamtunda wa 50.8 ° kumpoto ndi 330.7 ° kumadzulo chakumadzulo mkati mwa Ismenius Lacus quadrangle. Ndiwotalika makilomita 236. Dzinali limatanthauza Bernard Lyot, katswiri wazakuthambo waku France (1897-1952). © Chithunzi Pazithunzi: Wikimedia Commons

Kukula kwa phirili kumakhudza momwe nyanjayi inaliri yamphamvu kwambiri, ndipo chikhoza kukhala chimodzi mwa zifukwa zazikulu zomwe Mars tsopano ali "chipululu."

Mphamvu ya comet ikadatha kuwononga dongosolo la mapulaneti a Mars. Zikanakhala zoopsa mwamphamvu pakusintha kwanyengo padziko lonse lapansi. Kodi ndizotheka kuti Mars anali ndi moyo kalekale asanawononge mpweya wake?

Ngakhale zitukuko zomwe kale zinkatcha Mars "kwawo" tsopano zatha. Ngati ndi choncho, a Martians adapita kuti? Kodi adatha kukhala amoyo? Kodi adatha kuthawa tsoka lisanafike? Kodi Mars yolumikizidwa ndi Dziko Lapansi mwanjira iliyonse? Awa ndi ochepa chabe mwa mafunso ambiri omwe amafunikira kuyankhidwa.

Viking I ndinafika ku cholinga chake, Mars, pa Julayi 20, 1976, titayenda kwa miyezi khumi kuchokera ku Earth. Zithunzi zomwe Viking I adabwerera ku Earth zinali zodabwitsa, ndipo zina mwa izo zidawulula kuti Mars sanali osiyana ndi Dziko Lapansi.

Madera ena ku Mars, monga Death Valley, ndi ofanana ndi malo Padziko Lapansi. Pambuyo poyesa mayeso osiyanasiyana pofunafuna moyo pa Mars, nkhani ya Viking I imakhala yosangalatsa kwambiri. Viking ndinabwezera zotsatira zotsutsana.

Dr. Gil Levin adapanga mayeso a Viking, omwe anali mayeso "osavuta". Iye anafotokoza kuti tizilombo ting'onoting'ono, monga inu ndi ine ndi zina zonse, timapuma kenako timatulutsa mpweya woipa.

NASA idatolera pang'ono dothi la Martian ndikuyiyika mkati mwa chidebe chaching'ono, chomwe chidawunikidwa sabata limodzi ngati zisonyezo za "thovu" mkati mwa chubu, kenako china chake chosayembekezeka chidachitika patatha masiku asanu ndi awiri.

Malinga ndi miyezo ya NASA, kuyesa kwa moyo pa Mars kunali koyenera chifukwa "thovu" lidawoneka mkati mwa chidebe cha Viking I. Mayeso ena okhala ndi njira zosiyanasiyana adabweranso alibe, pomwe mayeso amodzi adabweranso ali ndi moyo.

NASA idasankha kukhala osamala pankhaniyi, nati, "Palibe umboni wotsimikizira kuti ku Mars kuli moyo." Malinga ndi asayansi ena, Mars kale anali ndi mlengalenga wofanana ndi Dziko Lapansi, koma adafafanizidwa zaka 65 miliyoni zapitazo.

Kuphatikiza pa chiphunzitsochi, m'mbuyomu anthu akhala akuganiza kuti chitukuko chomwe kale chimakhala ku Mars chikhoza kuthawira ku Earth kufunafuna malo abwino. Ndiye, kodi tsopano tili oyenerera kukhala "Martians" omwe takhala tikufuna?

Asayansi ena akuti apeza umboni wamphamvu wazithunzithunzi za Mars zomwe zatha, ndikuti atha kukhala kuti apeza chizindikiro cha nyukiliya mumlengalenga cha Martian chomwe chikufanana ndi dziko lapansi pambuyo poyesedwa kwa nyukiliya.

Malinga ndi asayansi, umboni wa Xenon-129 ukhoza kupezeka kwambiri ku Mars, ndipo njira yokhayo yodziwika yomwe imapangitsa Xenon-129 kuphulika kwa nyukiliya. Kodi ichi ndi chitsanzo china chofananira cha Mars ndi Dziko Lapansi? Kapena kodi zikutsimikizira kuti Mars kale anali malo osiyana kwambiri?
