Pfupisa nyaya yacho:  NASA yakasarudza makambani akasiyana-siyana kuti ashande pamapurojekiti okuumba unyanzvi hwokugadzira zvinhu zvomuchadenga hwemberi, kubatanidza nzira dzokukurumidza dzokufambisa. Mamwe mapurojekiti anoshanda anosanganisira kuvandudzwa kwenzvimbo dzokugara dzevanhu, uye masatellite maduku okuongorora nzvimbo huru. Uye imwe yemakambani ari mu12 Anotevera Michina Yomuchadenga Yokubatana Nokuongorora (NextStep) inoti ine injini inogona kuendesa vanhu kuMars mumazuva 39 chete. Dzorera pasi kuti uone vhidhiyo. NASA yakasarudza makambani akasiyana-siyana kuti ashande pamapurojekiti okugadzira unyanzvi hwokugadzira nzvimbo hwakapfuurira mberi, kubatanidza nzira inokurumidza yokukurudzira inozivikanwa seVasimr (inoratidzwa), iyo sezviri pachena yaigona kusvika kuMars munhau yamavhiki, kwete mwedzi. Injini yeVasimr - iyo inoshandisa plasma sechinhu chinotyaira - iri kugadzirwa nekambani yeAd Astra Rocket muTexas. Injini yavo yakakurumbira makore mashomanene apfuura apo kwakaziviswa kuti yaigona kuderedza zvikuru nguva yokufamba kuenda kuMars kubva pamwedzi kusvika kumavhiki - kunyange zvazvo ingada simba renyukireya. Uye pashure pokuedzwa kwakabudirira kwomuenzaniso womuenzaniso muna 2013, kunoratidzika kuti NASA zvino iri kuurangarira nokuda kwokushandiswa parwendo rwomunguva yemberi rwokuMars. Vasimr ishoko rinopfupikisa rokuti Variable Specific Impulse Magnetoplasma Rocket, rinoshanda neplasma, gasi rine simba remagetsi rinogona kupiswa kusvika patembiricha dzakakwirira nemasaisai eredhiyo uye rinogona kudzorwa uye kutungamirirwa neminda yemagineti yakasimba. Munda wemagineti unodzivirirawo zvivako zviri pedyo nokudaro tembiricha dzokupedza utsi dzinogona kuwanwa dzinopfuura zvikuru nzvimbo inonyunguduka yezvinhu. Mukushanda kwamaroketi, tembiricha yegasi rinobuda mumotokari inenge yakakwirira zvikuru, kumhanya kwayo kunenge kwakakwirira zvikuru uye kushanda zvakanaka kwepeturu kunenge kwakakwirira zvikuru. Roketi dzeplasma dzinobudisa gasi rinokurumidza kupfuura rinowanika nemamwe makemikari, saka dzinopedza mafuta mashoma chaizvo. "Tiri kufara zvikuru nechiziviso ichi uye tinodada kubatana neNASA mumatanho ekupedzisira ekugadzirwa kwetekinoroji", akadaro Dr Franklin Chang Diaz, sachigaro weAd Astra uye CEO, muchitaurwa. <unk>Tinotarisira kubatana kunobudirira zvikuru sezvatinofambisira mberi pamwe chete...
Kambani muTexas yakakumbirwa kukudziridza injini yayo inoshandura zvinhu. Injini yeVasimr yeAd Astra sezviri pachena yaigona kusvika kuMars mumazuva 39. Icho chimwe chezvirongwa 12 zvemichina yemhando yepamusoro zvichapiwa mari neNASA. Zvimwe zvinosanganisira marudzi matsva enzvimbo dzokugara uye masatellite maduku ari munzvimbo dziri kure dzenyika.
