Nasin helikopter Ingenuity <\/figcaption><\/figure>\n

Helikopter, ki tehta pribli\u017eno 1,8 kilograma, se je od roverja lo\u010dil preteklo soboto. Po prvi uspe\u0161no prestani no\u010di na povr\u0161ju Marsa je Nasa sporo\u010dila, da je “to velik mejnik” za malo plovilo. To je namre\u010d pokazalo, da ima helikopter ustrezno izolacijo, ustrezne grelce in dovolj energije v svoji bateriji, da lahko pre\u017eivi mrzlo no\u010d. Na Marsu namre\u010d lahko temperatura pade tudi do minus 90 stopinj Celzija.<\/p>\n

Zra\u010dna plovila so hitrej\u0161a kot roverji<\/h2>\n

V naslednjih dneh so preizku\u0161ali propelerje in motorje, rover pa je naredil tudi selfie skupaj s helikopterjem.<\/p>\n

Ingenuity oziroma Iznajdljivost bo prvi\u010d poskusil vzleteti \u0161ele zve\u010der. Bo sicer prvo zra\u010dno plovilo, ki bo sku\u0161alo opraviti nadzorovan motorni polet na drugem planetu.<\/p>\n

Polet bo velik izziv tudi zato, ker je gostota Marsove atmosfere enaka odstotku gostote Zemljine atmosfere. Mu bo pa pomagala te\u017enost, ki je na Marsu enaka tretjini te\u017enosti na Zemlji.<\/p>\n

Predvidoma se bo helikopter v treh sekundah dvignil na tri metre, kjer bo ostal pribli\u017eno 30 sekund, nato pa se bo vrnil nazaj na povr\u0161je rde\u010dega planeta. Med poletom bo Ingenuity, ki nima znanstvenih instrumentov, fotografiral v visoki lo\u010dljivosti. V prihodnjih 30 dneh bo predvidoma opravil \u0161e ve\u010d poletov.<\/p>\n

Helikopter je Naso stal 85 milijonov ameri\u0161kih dolarjev (71,5 milijona evrov). Namenjen je predvsem preizkusu koncepta, ki bi lahko mo\u010dno spremenil raziskovanje vesolja. Zra\u010dna plovila bi lahko v prihodnje raziskovala precej hitreje kot roverji, pri \u010demer bi la\u017eje raziskovala tudi bolj neravne terene.<\/p>\n

Poskus poleta sovpada s 60. obletnico, odkar je ruski kozmonavt Jurij Gagarin kot prvi \u010dlovek poletel v vesolje, in 40. obletnico od prve izstrelitve raketoplana Columbia. Na helikopterju je tudi ko\u0161\u010dek blaga s krila letala bratov Wright, ki sta leta 1903 opravila prvi motorni let na Zemlji.<\/p>\n

Nasa je rover Perseverance oziroma Vztrajnost izstrelila julija lani z izstreli\u0161\u010da v Cape Canaveralu, na Marsu pa je pristalo sredi februarja. Pribli\u017eno 1040 kilogramov te\u017eko vozilo i\u0161\u010de morebitne znake \u017eivljenja na rde\u010dem planetu ter prou\u010duje njegovo atmosfero in geologijo.<\/p>\n","protected":false},"excerpt":{"rendered":"
