Thawj cov duab ntawm Mars .. fascinate NASA cov kws tshawb fawb

sai li sai tau thaum nws kov lub npoo ntawm Mars hnub Thursday dhau los, Perseverance spacecraft, uas hnyav 1050 kg, thiab raug nqi ob billion thiab 700 lab daus las, kis thawj daim duab ntawm ib cheeb tsam ntawm Jesero crater, qhov chaw nws tsaws mus kawm nws geological. Qhov xwm txheej, thiab tshawb nrhiav 687 hnub rau ib qho kab ntawm lub neej uas tshwm sim hauv nws ib puag ncig yav dhau los ntawm lub ntiaj teb, Vim Jezero yog 3 billion thiab 500 lab xyoo dhau los, zoo li lub pas dej nrog txoj kab uas hla 49 km, nplua nuj nyob hauv dej. ntws mus rau hauv nws los ntawm ob txoj kev uas tshwm sim hauv cov duab thaum lawv delt los ntawm tus dej uas tau faib ua ob ceg.

Tom qab ntawd, lub dav hlau txuas ntxiv mus thaij duab ntawm thaj chaw ib puag ncig thiab xa mus rau NASA pab pawg tswj hwm hauv av, uas yog cov duab luam tawm los ntawm Al-Arabiya.net nrog kev piav qhia ntawm lub vev xaib ntawm US chaw haujlwm chaw haujlwm nws tus kheej. Raws li qhov zoo siab ntawm lawv, lawv tau tshaj tawm hauv qab no, thiab tau khaws los ntawm NASA kev sojntsuam hu ua Mars Reconnaissance Orbiter, uas tau nyob ib puag ncig Mars txij li xyoo 2006. Lub dav hlau tau tshwm sim hauv nws tom qab nws nkag mus rau hauv nws lub dav hlau thiab lub parachute txo nws txoj haujlwm. ceev mus rau nws qhov chaw ua ntej npaj tsaws, thiab ib lub radar nruab rau hauv nws coj nws mus rau nws.

Qhov thib ob yog qhov zoo siab, uas lub tsheb zoo li tau tsaws rau saum npoo ntawm lub ntiaj teb, tom qab nws tau sib cais los ntawm qhov lawv hu ua "cov ntaub thaiv npog", uas yog tsim los tiv thaiv nws los ntawm cov cua kub kub los ntawm kev sib txhuam nrog cov Lub ntiaj teb lub dav hlau thaum nws nkag mus rau hauv nws, ces lub parachute nrog ib txoj kab uas hla ntawm 21 meters tau saib xyuas ntawm nws, thiab thaum nws mus txog 31-square-meter lub voj voog ntawm lub crater, npaj ua ntej rau nws tsaws, nws sib cais los ntawm nws thiab xa. nws dhau mus rau lwm qhov chaw tsaws.

Lwm qhov kev tsaws yog lub "celestial platform" paub ua lus Askiv li lub skycrane.Qhov kev ceev ntawm qhovntsej thiaj tsis mob rov qab los, uas lub tsheb nqis los dai nrog cov hlua tshwj xeeb thiab cov xov hlau, raws li "Al Arabiya.net" nyeem nyob rau ntawm NASA lub vev xaib uas cov duab tau raug coj los ntawm lub koob yees duab tau teeb tsa hauv "celestinal platform." Nws kis mus rau lub dav hlau thaum nws nyob ntawm Martian dermis, thiab tig mus, cov khoom siv tes ua xa mus rau lub ntiaj teb, tom qab ntawd "platform. ” cais tawm ntawm nws mus tsoo rau lwm qhov chaw.

Raws li daim duab peb, Kuv khaws nws Lub koob yees duab hauv lub tsheb rau ib qho ntawm 6 lub log, uas yuav pib lub lim tiam tom ntej mus taug kev los ntawm qhov kev cia siab crater, thaum daim duab thib plaub yog daim duab los ntawm "NASA" hais txog kev siv tshuab navigation tshiab ntsig txog thaj av "kom tsis txhob muaj kev phom sij thiab pom. Qhov chaw nyab xeeb rau tsaws hauv Jezero crater ntawm Mars, "raws li cov duab piav qhia, cov ntawv tshaj tawm Nrog rau daim duab hauv qab no, thaj chaw xiav muaj kev nyab xeeb nyob rau hauv lub qhov tsua rau kev tsaws, thiab thaj chaw liab tsis siv tau, vim tias lawv rugged thiab pos. pits thiab pob zeb uas yuav cuam tshuam nrog Perseverance txoj kev taug kev ntawm Mars, uas nws tau mus txog tom qab taug kev 471 lab kilometers hauv kev taug kev uas siv 203 hnub, ntawm qhov ceev ntawm 96.000 kilometers ib teev.

Qhov loj tshaj plaws mus ntsib Mars yuav qhia ntau yam txog Red Planet

Cov engineers dazzled los ntawm NASA cov duab

Hauv daim duab duab, peb pom tias thaj chaw tsaws yog xim ntsuab, raws li qhov txawv ntawm tsab ntawv ceeb toom los ntawm "Jet Propulsion Laboratory" soj ntsuam qhov sophisticated thiab complex tshaj plaws ntawm Mars missions uas NASA tau ua kom deb li deb, muab hais tias Perseverance yog nruab. nrog lub tshuab cocktail txhim kho nrog kev txawj ntse uas tsis muaj hmoo rau lwm lub dav hlau.

Cov kws tshawb fawb thiab cov kws tshaj lij ntawm "NASA" tau ntxim nyiam los ntawm cov duab, txawm tias lawv tsawg, thiab ib tus ntawm lawv yog Steve Collins, tus kws tshaj lij tswj hwm ntawm "Birth Propulsion Laboratory" hauv California, tau hais nag hmo, tias nws "tso siab rau hauv ib qho daze thiab xav tsis thoob," ntxiv tias Asmeskas chaw haujlwm chaw haujlwm "tau txais qee yam zoo heev." Tiag tiag," nws hais.
