The ikuku nke Mars: ihe-omimi nke anọ planet

Mars, nke anọ planet si Sun anya, dịwo anya a isiokwu nke uche nke ụwa sayensị. Nke a planet dị yiri nnọọ Earth na otu, a obere ma na-egbu egbu isịneke - na Martian ikuku bụ ihe na-erughị otu pasent nke ụwa ikuku. The gaseous envelopu nke mbara ala ọ bụla bụ a ikpebi ihe n'ịkpụzi ọdịdị ya na n'elu ọnọdụ. Ọ maara na ihe niile siri ike ụwa anyanwụ usoro guzobere dị na otu ọnọdụ na mpaghara 240 Mill. Kilomita n'ebe anyanwụ. Ọ bụrụ na ọnọdụ nke guzobe nke Earth na Mars ahụ yiri, mgbe ahụ, ihe mere ugbu a ndị a mbara ala dị nnọọ iche?

The dum ebe nha - Mars kpụrụ si otu ihe dị ka Earth nwere mgbe mmiri mmiri na-ekpo ọkụ dara isi, nakwa dị ka ụwa anyị. Gosiri - ọtụtụ nwuchapu agbọpụta ọkụ na elu nke Mars. Ma "red planet" dị nnọọ obere karịa Earth. Ya mere, na ya dajụrụ ngwa ngwa. Mgbe mmiri mmiri isi kpamkpam mma na obi tara mmiri, dechara usoro nke convection, na ya okụrede, na magnetik ọta nke mbara ala - na magnetosphere. Adịru planet ekpe inyeaka megide ebibi ike nke anyanwụ, na Mars ikuku a fọrọ nke nta kpamkpam fụọ site anyanwụ ifufe (ibu redioaktivu iyi nke ionized ahụ). "Red Planet" aghọwo a na-adịghị ndụ desert mwute ...

Ugbu a ikuku na Mars bụ a mkpa shei nke a atara gas na-adịghị ike inogide na penetration nke na-egbu egbu anyanwụ radieshon, nke na-agbakwa elu nke ụwa. Mars thermal ntụrụndụ site ọtụtụ iwu nke ịdị ukwuu nta karịa nke, n'ihi na ihe atụ, Venus, onye ikuku bụ ọtụtụ denser. Mars ikuku na-enwe a oke ala thermal ike site ọzọ akpọ kwa ụbọchị nkezi ifufe ọsọ egosi.

Mejupụtara Mars ikuku ji a nnọọ elu ọdịnaya nke carbon dioxide (95%). Ọzọkwa, ikuku nwere nitrogen (banyere 2,7%), argon (banyere 1.6%) na a obere ego nke oxygen (ọ dịghị ihe karịrị 0,13%). Ikuku mgbali nke Mars bụ 160 ugboro elu karịa elu nke ụwa. N'adịghị ka ndị n'ụwa, ndị gas envelopu ebe a nwere a akpọ agbanwe agbanwe agwa n'ihi na eziokwu na polar okpu nke mbara ala, nwere nnukwu ego nke carbon dioxide, na gbazee freezes maka otu afọ okirikiri.

Dị ka data nwetara site na a nnyocha ugboelu «Mars Express», Mars ikuku nwere ụfọdụ ukwu nke methane. The peculiarity nke gas bụ ya ngwa ngwa nkịtị. Nke a pụtara na ebe ndị dị n'ụwa kwesịrị ịbụ isi iyi nke methane replenishment. Nhọrọ nwere ike ịbụ nanị abụọ ebe a - ma ọ bụ geologic ọrụ, metụtara nke a na-ahụghị, ma ọ bụ ọrụ nke microorganisms, nke bụ ike iji agbanwe nghọta anyị nke ọnụnọ nke-eri ego nke ndụ na mbara igwe.

E ji mara mmetụta Mars ikuku bụ ájá oké ifufe, nke nwere ike iwe ọnwa. Nke a ikuku uko cover planet mejupụtara tumadi nke carbon dioxide na obere inclusions nke oxygen na mmiri vepo. Nke a bụ n'ihi na-egbu oge mmetụta nke nnọọ ala ndọda nke Mars, ikwe ka ọbụna ibu-rarefied ikuku weliri n'elu ma jide ruo ogologo oge, ọtụtụ ijeri tọn ájá.
