Ogaaday in Xiisaha rover caalamka cas

Sahminta faraare ayaa hadda si taxadar leh isagoo. The wax-u Red Planet - ugu heli karo waxbarasho. Si ka duwan Venus, Mars waxay leedahay cimilo friendlier iyo deegaanka. Waxa uu cilmi baaris iyadoo la kaashanayo Xiisaha rover - taasi waa isku daygii saddexaad Americans daaha ka qarsoon oo meeraha afraad.

Mars rover Xiisaha - rover waxaa loogu talagalay in xarun cilmi-bannaan oo American ah NASA. Waxa uu adag yahay a joofane. rover waa ay awoodaan in ay u safraan masaafo dheer, qalabaysan a "gacanta" ee doorashada ee dhulka ama walxaha kale ee falanqaynta leh. Waxa kale oo uu leeyahay unit laser for falanqaynta spectrographic oo ka mid ah dhagaxa weyn Red Planet ah.

In Arsenal ee rover uu leeyahay toban qaybood cilmi falanqayn kiimikada kala duwan. Its miisaanka waa 900 kg, oo dhererkeedu wuxuu -. 3 m Rover awood u xawaare ilaa 12.5 km / h. Si kastaba ha ahaatee, waayo, farsamadaan si loo cabbiro xawaaraha la taaban karo ee sentimitir per labaad halka Xiisaha rover uu leeyahay xawaare sare ee 3.5 cm / s. Mid kasta oo ka mid ah lixdii giraangiraha ay ku qalabeysan ay engine. isteerinka Independent qalabaysan ma aha oo kaliya drive hor-wheel ah, laakiin labada dib, kaas oo u ogolaanaya rover si fudud u gudbaan expanses Martian. Farqiga ugu muhiimsan ee u dhexeeya rover-ka lagu daydo hore, sida Mars Rover "Ruuxa" iyo walaalkiis mataanaha, "Opportunity" - in korontada ah. Haddii Rovers ka hor "quudin" by tamarta cadceedda, Xiisaha rover leeyahay il nuclear tamarta oo u oggolaan doonaa in isaga si ay u qabtaan hawlo muddo hal sano ah Martian.

Intii uu talada hayey, rover ayaa qaatay wax badan oo cilmi-baaris. natiijooyinka ay muujiyaan in ee la soo dhaafay ka fog Mars ahaa ku haboon nolosha. In ciidda iyo dhagaxyada meerayaasha ayaa laga helay walxaha sida baaruud, oxygen, nitrogen iyo xubno kale oo lagama maarmaan u ah nolosha.

rover cajiib sameeyaa cilmi baaris ay weheliyaan sariirta webiga qadiimiga suurto gal, ama waxaa la xilliyo gaar qabanaysa gudubno. Its farqiga ugu weyn ee meelaha kale, in aanay ahayn ku xiran lagu qayilo kadis ah, iyo waxa aan ahaa mid aad u cusbada. Taasi waa, in meesha this lahaa oo dhan shuruudaha lagama maarmaanka u ah ah ee noolaha ugu fudud in ku siin karaan horumarinta nolosha caalamka. In tijaabada la soo xulay in ka badan 20% waxay ka kooban tahay dhoobo, waxay muujinaysaa in ay jirto is dhexgalka oo biyo ah iyo dhagaxyada. Sidoo kale ciidda of sulphate calcium, taasoo muujinaysa in ay dhexdhexaadnimada.

rover waxa ay ogaatay in kiimikada ah qayb ahaan uun oxidized. On Earth, waxa ay keentay lahaa in si weynna u kobcay bakteeriyada. Xaqiiqada ah in meesha bartay maahin meelaha oxidized noqday kuwa loo yaqaan kadib marka ay bilaabaan dusha rover qodista ee. meelaha ciidda halkan, si ka duwan inta kale ee dunida, lahaa galyadeena cirro, ma cas.

Ujeedada ugu weyn ee rover - Mount Sharp ee ag tuuli maayo dhexe ee bohol Gale, laakiin waddada si ay u bilaabaan ka dib markii baadhitaan dhamaystiran of Yellowknife Bay, halkaas oo rover Xiisaha ay u qabtaan cilmi-baarista la joogo, ka dib markii dhamaystirka taas oo ilaa dhinaca reer bohol ku dhaqaaqi doono.

rover gacanta ka Earth. Waa arrin aad u adag, hal qalad keeni kartaa in burburinta rover, ama xaqiiqda ah in uu kaliya ku xayiran on bacaad ah, sida ay horreeyay "Ruuxa".
