Flight International ya ba da rahoton cewa binciken farko na ESA ya nuna ƙasa da kwatankwacin hayakin CO2 na fasinja a cikin jirgin sama kamar yadda za a samar da shi ta hanyar wucewa ta cikin jigilar mutane. ESA bai riga ya shirya sakin cikakkun bayanai ba, duk da haka, yana shirin yin bincike dalla-dalla.
"Ba na son sakin alkalummanmu kafin mu yi cikakken bayani," in ji Geraldine Naja-Corbin na ESA a yayin taron tattaunawar a makon da ya gabata.
Wani ɓangare na jirgin da ke cikin jirgi zai ƙunshi yanayin ballistic a waje da sararin samaniya, tare da kumbon jirgin da ke tafiya cikin sauri kuma yana fuskantar ƙasa da ƙasa - kusan ƙarancin mahimmanci - matakan ja.

Wancan ya ce, don samun saurin gudu da hawa saman yanayi a farkon wuri roket jirgin yawon shakatawa dole ne ya kashe makamashi mai yawa. Lokaci na ballistic na ayyukan da aka tsara a halin yanzu kamar su Virgin Galactic zai iya zama takaitacce, shima - amma fa waɗannan ba tafiye tafiye bane wuri, don haka kwatankwacin kwatankwacin CO2 kwatankwacin mil fasinja ba zai yiwu ba. (Jirgin sama na Virgin Galactic zai tashi daga nan kuma ya dawo ya sauka a wuri ɗaya, filin jirgin saman New Mexico.)
Bayan haka, idan mutum yana so ya zama mai karba, zai iya lura cewa don hawa sararin samaniya na musamman yawo abokin ciniki na yau da kullun zai yi doguwar tafiya ta hanyar jirgin sama na yau da kullun zuwa da kuma daga wurin ƙaddamarwa, kuma wataƙila kafin a fara horo.
