Kusetshenziswa imininingwane eqoqwe yi-NASA Insight SpaceCraft, iqembu lamazwe omhlaba labaphenyi babale usayizi we-Mars Kernel. Imiphumela yomsebenzi yindaba yengxoxo yengqungquthela ye-52nd Lunar nePlanethi, okubanjelwe kulo nyaka ngemodi eku-inthanethi.
Ngokuhambisana namamodeli wesimanje, isakhiwo sangaphakathi sama-MARS simelelwa amagxolo, i-mantle kanye nomnyombo. Ubukhulu obuphakathi kwamagxolo bungaba ngamakhilomitha angama-50 (esiphezulu - kuze kufike ku-125 km). Kuthatha u-4.4% womhlaba wonke.
I-mantle iqukethe izingxenye ezingenhla, eziphakathi nendawo ezingezansi. Uma kuqhathaniswa nomhlaba, kubonakaliswa yibanga elincane lokucindezela ngenxa yokudonsela phansi okunamandla kangaka. Amaminerali nezilimo, ngokwesibonelo, amabhomu, ama-olivine nama-pyroxes, ahlukaniswe e-mantle.
Ngokusho kososayensi, i-kernel iphelele noma ngokwengxenye esimweni esiwuketshezi. Kukhona ekwakhiweni kwalo ikakhulukazi kwensimbi ngokuhlanganiswa kwesibabule, i-nickel ne-hydrogen. Phambilini, kungenzeka ukukala usayizi we-nuclei yezwe kuphela kanye nenyanga. Kulokhu, abacwaningi basebenzise idatha yokuzamazama komhlaba.
Umnyombo wendlela ukulandelela ukuzamazama komhlaba. Ngosizo lwezinzwa ezikhethekile, imisindo evela ngesikhathi sama-jolts angaphansi komhlaba nama-oscillation aqoqwa. Ukukala usayizi we-mars kernel ngendlela efanayo, i-NASA yethule i-innight mission emuva ngo-2018. Umsebenzi wayo ophambili kwakuwukulethwa ebusweni beplanethi ebomvu yohlelo lokutshala olune-seismometer ebhodini.
Izinhloso zesayensi ezibonakalayo emkhakheni wokuvela kwezwe le-Mars:
- Ukukalwa kosayizi, ukwakheka, isimo se-aggregate kernel;
- Ukuchazwa kwesakhiwo, ubukhulu, ukwakheka kwamagxolo kanye ne-mantle;
- Ukulinganiswa kokushisa kwezingqimba zangaphakathi zeplanethi.
Idivaysi ifike kude kude ne-equator yeplanethi. Kuleli phuzu kuqhubeke, kwaqala ukubonwa "kwabezimabula". Kusukela ngo-2018, izinzwa ziqophe cishe ama-500 soles futhi zibhalise inani elihambisanayo ledatha yokuzamazama komhlaba. Uma uqhathanisa nokuzamazama komhlaba kwe-oscillation yobuso beMars, ezimweni eziningi buthaka.
Futhi phakathi kwawo kukhona amajackethi acishe abe ngu-50 ane-magnitude 2-4 (iRichter Scale inikezela ngezinkomba kusuka ku-1 kuye ku-9.5). Lezi zinkwane zaphenduka ziqine ngokwanele ukuze zisetshenziselwe ukukala izici zangaphakathi zeplanethi. Phambilini, sibonga ngokunembile kwimininingwane yokuqonda, ososayensi basungule ukujula okulinganiselwayo nobukhulu bezendlalelo zamagxolo ama-MARS.
Izinzwa ze-seismographic zibamba izinkomba eziningi, ngesisekelo sabo ochwepheshe abangabasi usayizi wezingxenye zangaphakathi zesakhiwo somzimba weplanethi. Isibonelo, balungisa, kukuphi ukujula, amaza avela ngenxa yokuzamazama komhlaba kuqala futhi aphela. Le yindlela yokubalwa yenziwa ngayo, eyayidingeka endimeni yegagasi ngokusebenzisa esinye isifunda seplanethi.
Okulandelayo, ukusungulwa kwezendlalelo kuyasungulwa futhi, ekugcineni, ukujula kwemingcele phakathi komgogodla kanye nengubo ezingxenyeni ezahlukene zeplanethi kunqunywe. Yonke le mininingwane yasivumela ukubala ukuthi i-radius ye-nucleus ingaphakathi kwe-1810-1860 km - cishe isigamu sobukhulu bomgogodla womhlaba.
Imiphumela yocwaningo yayilindelekile ososayensi, ngoba phambilini bekukholelwa ukuthi inkulu kakhulu. Futhi ubuningi bengxenye ephakathi yeplanethi cishe bungama-6700 kg / m3. I-Set radius inika isizathu sokukholelwa ukuthi i-kernel ingamaphaphu amaningi kunalokho obekulindelwe.
