Panguva yekutaura kureba kwakaita alpha centaur kubva panyika Tinofanira kufunga kuti kana tichitaura maererano nemakiromita, tinofanira kuita masvomhu zvakanaka kwazvo, sezvo gore rakareruka richiita 9.461.000.000.000 km, towanza ne4,36 zvinopa huwandu hwe41.249.960.000.000. take.
Alpha Centaur iri kure sei kubva kuPasi?
Tisati tataura kuti Alpha Centauri ari kure sei kubva kuPasi, zvakakosha kuratidza kuti chikamu ichi chemuchadenga chinopfuura katatu nyeredzi system o mapoka enyeredzi, iyo maererano nezvidzidzo zvakasiyana-siyana ndiyo iri padyo nesolar system yedu sezvo iri 4.22 light years away. Munhevedzano iyi yepfungwa, boka iri renyeredzi rinoumbwawo nemamwe maarufa maviri, ndiko kuti, Alpha Centauri A uye B, ari kure nemakiromita 4,36 echiedza. Kuti uwane rumwe ruzivo, unogona kubvunza nezve distance to Alpha Centauri kana the nyeredzi dzenyeredzi.
Rwendo rwekuenda kuAlpha Centauri
Isu tatoziva kuti pane nyeredzi imwe chete munyeredzi iri padyo neZuva Uye, tichifunga kuti Alpha Centauri iri fomula yakaumbwa nenyeredzi nhatu Zvingangodaro kuti kune akawanda akawanda. Sezvo takanzwa nhau yokuwanikwa kwacho, vakawanda vave vachinetseka kuti zvaizotora nguva yakareba sei kuti tiende kuAlpha Centauri kuti tizvionere pachedu nyika itsva. Kuda kuziva uku kunogona kuenderana ne mapoka enyeredzi uye kukosha kwawo mukufamba.
Maonero enyanzvi aAlpha Centauri Bb
Ndechipi chinhambwe chiri alpha centaur kubva pasi uye icho chinozove icho chiri pedyo nesolar system Zvinogona kutaurwa kuti zvinotora makore makumi maviri kana makumi matatu. Nguva refu, hongu, asi isingasviki paavhareji yehupenyu hwemunhu chero upi zvake. Kufamba muchadenga kwakaoma zvechokwadi, chiitiko chakakodzera mhando dzakasimukira zvechokwadi. Nekudaro, ngationgororei sarudzo dzinobatsira zvakadzikama, senge mukana wekuongorora nyeredzi dzinozivikanwa kana kuti zvinorevei kureba pakati peAlpha Centauri nemamwe masisitimu.
Mamiriro enzvimbo
Chinhu chakanyanya vertiginous chemunhu chatakadzinga kunze kwe Solar system IVoyager 1. Iyi probe inoremekedzeka iri kufamba kubva kuZuva nekumhanya kwe17,4 km/s, kana makiromita angangoita 540 miriyoni pagore. Asi Alpha Centauri ari 4,37 light-years away - kana 272 matenga ekudenga - chimiro chinoderedzwa kusvika 000 chiedza-makore munyaya yediki Proxima Centauri. Pakumhanya uku, Voyager 4,24 ingave makore 1 76000 kumashure mukusvika Alpha Centauri, achifungidzira kuti yaifamba ichienda kwairi. Hazvina maturo kutaura, Voyager haisi chikepe cheastral chakanyatsokodzera kuti uone chinhambwe pakati penyeredzi.
Netekinoroji inoshandisika ingave mukana wekutumira chitundumuseremusere kubva muSolar System kupenya zvakapetwa kashanu kusvika kagumi pane Voyager 1. Serious yakafumurwa ya NASA kugadzirisa 'interstellar' probes inokwanisa kushanda Oort Cloud kana heliopause, anoyambira kubudirira rwendo rwemakiromita mamiriyoni 150 mumakore gumi nemashanu kana makumi matatu. Zvakanaka, zvinoratidzika kuti tiri kubudirira, kusvikira taona kuti chinhambwe ichi hachisviki 000% yegore rakajeka. Isu tinotevera zvakafanana nekutangwa.
Kuti tisvike kuAlpha Centauri mukati menguva inoshiviririka, kumhanya kwatinofanira kuwana kunofanira kunge kuri zviuru gumi zvemakiromita pasekondi. Tichimhanya kudaro taizosvika makore 130, izvo zvinogona kufungidzira kugumbuka kana zvimwe tichifunga nezvetsika ine vakawanda vedu yokufa tisati tasvitsa makore zana. Kana tikafamba pa100 km/s, nguva yekubhururuka inoiswa pasi pemakore makumi mashanu.
Hafu yezana haina kuipa kune rwendo nzvimbo, saka uku kunofanira kunge kuri kumhanya kwatinofanira kufunga nezvako kana tawana, zvinonetsa kana tikasimudzira Voyager 1 kubhobhowa kuri pasi pe18 km/s.
Zviripachena kuti isu hatina imwe sarudzo kunze kwekushandisa propulsion masisitimu kunze kweaya akajairwa, saka isu zviri nani tikanganwe nezve yainzi kemikari kutanga inoshandiswa neakajairwa projectiles. Nokuti? Zvakanaka, kana tichida kuwana 1% yekumhanya kwechiedza (3000 km / s) tichishandisa maroketi emakemikari akajairwa, tingada 1026 kg yezvinhu zvinopfuta pakg yega yega yehuremu hwechikepe. Kureva kuti ngarava iyoyo yaizoguma yave neka100 kuwanda kwePasi.
Mune imwe kurongeka kwemazano, kana tichida kuenda kuAlpha Centauri muzana rino ramakore tinofanira kuita yananiso. Semuenzaniso, siya kunze kwezvikepe zvinotyairwa. Machina probes achave akadzika zvakanyanya uye akaomarara. Panguva imwecheteyo, tinogona kufungidzira mishoni inongogumira pakupfuura alpha centaur pasina kuomerwa kutenderedza uye kupinda muorbit pedyo neimwe yenyeredzi mbiri dzekutanga, izvo zvingafungidzira kushandiswa kwesimba kwakanyanyisa.
Inopisa nyukireya uye ionic kutanga
Iyo yemagetsi thrust - ionic kana plasma - parizvino inoshandiswa mune akati wandei spacecraft uye inokwanisa kuwana chaiyo propulsion yemasekonzi akati wandei. Atomic thermal launch inotevera zvishoma kumashure. Aya madhiraivha masisitimu haana kushata zvachose kukwira achitenderera Solar system, asi zvaizotitorera makore anenge 40.000 XNUMX kuti tisvike Alpha Centauri.
ngarava dzezuva
Pano tinotanga kufamba munzvimbo inoyevedza. Sairi yezuva mukutaura kwendege dzekudenga. Mupfungwa iyi, izvi hazvisi kenduru iri nyore photonics kufanana neJapan Ikaros. Chirevanguva chekuti 'solar' chine chikonzero. Chikepe chezuva chakavakirwa pakuparadzirwa kunotyisa nekumiririrwa kwemaparachute ayo, senge chikepe chephotonic, angashandisa kumanikidza kwechiedza chezuva - uye kwete iyo yemhepo yezuva sezvo dzimwe nguva ichinyungudutswa zvisizvo- kukurumidza kuenda muchadenga kuenda nekukurumidza. kubva kuSolar System. Asi kuti ushandise iyi sisitimu zvinodikanwa kuwedzera chikepe chiri padyo cheZuva.
Nekune rimwe divi, tichifunga kuti mumakumi emakore ari kuuya isu tinokwanisa kugadzira zvikepe zvakareruka zvakakura zvinokwanisa kumira kupfuura 60 g yekukasira uye zviuru zvemadhigirii Celsius, chikepe chezuva chinogona kufamba kusvika. alpha centaur mumakore chiuru kana zviuru zviviri. Zvichiri kuitika zvakawanda, asi iyi system inogona kubatanidzwa nemamwe kuderedza nguva yekubhururuka.
Kuvhurwa kwenyukireya kuburikidza nenhevedzano yemapulses
Accredited chirongwa cheOrion Kubva ku60s, iyi system inoita seyapenga, asi chokwadi ndechekuti akasanganiswa seti ehunyanzvi akatoedzwa. Chikepe chenyukireya chiri kutenderera chinoputika zvinhu zveatomu chinhambwe kubva pamotokari. Vehement wave yakanyoroveswa nendiro chaiyo ine spirals, iyo inoendesa chikamu chesimba kuchikepe nenzira yekuti inomhanyisa zvishoma nezvishoma. Orion yaive mota yaivimbisa kufamba uchitenderedza Solar System, asi parwendo rwemuchadenga system iyi haina kunyengera.
Mukurongeka kwemazano uku, basa riri kuitwa rakakosha chaizvo nekuti nenzira iyi pane kutaurirana kukuru nezvingave. chinhambwe chiri pakati pealpha centauri nepasi redu.
Chekupedzisira, zvakakosha kuziva kuti ndechipi chinhambwe ichi alpha centaur kubva panyika chatinofanira kufunga pamusoro pemakore echiedza sezvataurwa pamusoro apa, mukuwedzera kune chokwadi chekuti kune makirasi akasiyana ezviyero zvingave nenguva yakareba kusvika. seti yedu nyeredzi padhuze, kunyatsojeka, anenge makore 150 kusvika Alpha Centauri. Hazvina kushata kune ngarava inosiyanisa, asi inoita kunge isiri iyo yakanyanya kufanira basa rinoratidza uye rine musoro rekutenda otomatiki kune avo vari kufa (kwete kutaura chaiko) kuziva zvishamiso zviri padyo nesolar system yedu uye naizvozvo, zvenyika yedu.
