Ntchito ya masiku 39 kupita ku Mars

Ulendo wopita ku Mars poyambirira ukanatenga pafupifupi masiku 300. Tsopano ndi luso latsopano la roketi za plasma, zitenga nthawi yocheperapo kasanu ndi kamodzi. Ndiko kulondola: masiku 39 okha kupita ku Mars.

Izi zimatheka ndi Variable Specific Impulse Magnetoplasma Rocket (VASIMR), njira yopita patsogolo yoyendetsa mlengalenga yomwe imagwiritsa ntchito mpweya wa argon ndi mafunde a wailesi monga kuwala - mphamvu yowonjezereka yomwe imapezeka mumlengalenga.

Ntchitoyi, motsogozedwa ndi Frank Chang-Díaz, yemwe kale anali wamlengalenga wa NASA yemwe wakhala akuyenda maulendo asanu ndi awiri ndipo adathera maola oposa 1 600 mumlengalenga, akupangidwa ndi Ad Astra Rocket Co. Ad Astra Rocket Co. mu ntchitoyi mpaka pano, koma Chang-Díaz akuti zidzatenga $ 30 miliyoni kuti roketi ikonzekere kupita.

Mayi Chang-Díaz ananena kuti: “Maroketi amtunduwu amakhala okwera kwambiri moti nthawi zonse amathamanga kwambiri. "M'mawu ena, zili ngati kuponda gasi osasiya."

Dzuwa, mphezi ndi ma TV a plasma ndizinthu zonse zomwe zili ndi plasma, imodzi mwazinthu zofunika kwambiri za VASIMR. Pali vuto limodzi lalikulu pakugwiritsa ntchito plasma, komabe: kumatentha kwambiri. M'malo mwake, imatha kupitilira madigiri 1 miliyoni. Pofuna kuthana ndi kutentha kumeneku, madzi a m'magazi amawongoleredwa motsatira njira ya maginito yomwe pamapeto pake amaitulutsa mu rocket, kuti ikhale yozizira mokwanira kuti igwire ntchito.

Roketi yatsopano ya plasma imapangitsa kuti ulendo wopita ku Mars ukhale mwachangu kasanu ndi kamodzi

Chang-Díaz anati: “Roketi ikatentha kwambiri, ndiye kuti roketiyo imakhala yabwino kwambiri. Vuto ndiloti simungakhale ndi zinthu zakuthupi pafupi ndi madzi a m'magazi otenthawa. Mwamwayi, titha kukhala ndi plasma yokhala ndi maginito. ”

Roketi ya plasma imabweretsa zambiri kuposa kuthekera kofika ku Mars mwachangu. Ndiwopanda mafuta kwambiri poyerekeza ndi rocket ya mankhwala ndipo m'malo mowotcha mafuta ambiri panthawi imodzi, rocket ya plasma imagwiritsa ntchito mafuta pang'ono omwe amathamangitsidwa pamtunda wautali kwa nthawi yaitali. Kuphatikiza apo, roketi ya plasma imatha kuyeretsa mlengalenga womwe ukuzungulira Dziko Lapansi, kukonza ma satellite, kukonza malo opangira mlengalenga, kuyambitsa zida kupita kunja kwa solar system mwachangu kuposa miyala yamankhwala ndikupotoza ma asteroid opita kudziko lapansi. .

Ma roketi a mankhwala amadziwika kuti amayenda pa liwiro la 40 000 mailosi pa ola, koma Chang-Díaz akuti roketi yatsopanoyi idzaphwanya mailosi 120 000 pa ola.

Monga matekinoloje atsopano ambiri, pali omwe amatsutsa lingaliro ili, kuphatikizapo Robert Zubrin, mtsogoleri wa Mars Society. M'nkhani yotchedwa "The VASIMR Hoax," Zubrin adalemba kuti "palibe chifukwa chilichonse chokhulupilira kuthekera kwa mphamvu yamphamvu ya Chang Diaz."

Zubrin akuti zida ndi ukadaulo wofunikira kuti amalize VASMIR zonse zilibe komanso sizigwira ntchito.

"Palibe magetsi oyendetsa magetsi-ngakhale otsika VASIMR kapena opikisana nawo apamwamba a ion-drive-angathe kukwaniritsa mofulumira kupita ku Mars," akulemba Zubrin. "Chiyerekezo champhamvu champhamvu chamagetsi aliwonse (ngakhale opanda malipiro) ndichotsika kwambiri."
