Alpha Centaur iri kure sei kubva kuPasi?
Tisati tataura kuti iyi alpha centaur iri kure sei kubva pasi, zvakakosha kuziva kuti chikamu ichi che cosmos 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, iyi seti yenyeredzi inoumbwa nemamwe maalphas maviri, ndiko kuti, alpha centauri A uye B, ayo ari kure ne4,36 light years.
Rwendo rwekuenda kuAlpha Centauri
Isu tinotoziva kuti mune inokwana nyeredzi imwe mukati Alpha Centauri, Nyeredzi iri padyo neZuva. Uye, tichifunga kuti Alpha Centauri chaizvoizvo iri formula yakaumbwa nenyeredzi nhatu sezvingabvira kune akawanda akawanda. Sezvo takaona nhau yokuwanwa, vakawanda vakashamisika kuti zvaizotora nguva yakareba sei kuti tiende kuAlpha Centauri kuti tizvionere timene nyika itsva.
Maonero enyanzvi aAlpha Centauri Bb
Ndechipi chinhambwe chiri alpha centaur kubva pasi uye icho chinozove icho chiri pedyo nesolar system zvinogona kunzi zvinotora makore makumi maviri kana makumi matatu. Nguva refu, hongu, asi pasi peavhareji yehupenyu hwemunhu chero upi zvake. Kufamba muchadenga kwakaoma zvechokwadi, chiitiko chayo chega mumhando dzakasimukira zvechokwadi. Zvisinei, ngationgororei sarudzo dzinobatsira zvakadzikama.
Mamiriro enzvimbo
Chinhu chakanyanya vertiginous chemunhu chatakadzinga kunze kwe Solar system iVoyager 1. Iyi probe inoremekedzeka iri kufamba kubva kuZuva ichimhanya 17,4 km/s, kana makiromita angangoita 540 miriyoni pagore. Asi Alpha Centauri ari 4,37 light-years kure-kana 272 matenga ematenga, digit inobereka 000 light-years muchiitiko cheProxima Centauri musikana. Pakumhanya uku, Voyager 4,24 ingave makore 1 76000 kumashure mukusvika Alpha Centauri, achifungidzira kuti yakafamba ichienda kwairi. Hazvina maturo kutaura, Voyager haisi nyeredzi yakanyatsokodzera.
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 muripo kunze kwekushandisa akasiyana masisitimu ekufungidzira pane akajairwa, saka isu taizokanganwa zvirinani nezve yainzi kemikari kutanga inoshandiswa neakajairwa projectiles. Sei? Zvakanaka, sezvo kana tichida kuwana 1% yekumhanya kwechiedza (3000 km / s) tichishandisa maroketi emakemikari akabvumirana, tinoda 1026 kg yekupisa kwekg yega yehuremu hwechikepe. Nemamwe mashoko, 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.
