<prompt> Pfupisa nyaya yacho: Nepo nyika yakakamukana pamusoro pokuti chipfeko ichocho ndechebhuruu nechitema here, kana kuti chena nendarama, NASA yave ichibatanidzwa mukukakavadzana kwayowo kworuvara. Nguva ino gakava racho rinobatanidza Mars inonzi pasi dzvuku iyo vanodzidzisa rangano vanodavira kuti iri chaizvoizvo yakasvibira uye yakasvibira. Vanopokana kuti sangano romuchadenga rakashandura ruvara rwemifananidzo yakabva kuMars kuti iratidzike yakatsvuka, orenji uye yepinki, mune izvo vanotaura kuva kuedza kufukidza upenyu papasi. Dzorera pasi kuti uone vhidhiyo. Gakava iri rave riripo kubvira muna 1970 apo Viking 1 yeNASA yakava chombo chokutanga chakasvika papuraneti tsvuku. Mifananidzo yaro yokutanga yakaratidza zvaiita sedenga rebhuruu kurudyi, asi chaizvoizvo NASA inoti pasi rine denga dzvukuorenji. Kuruboshwe pane mufananidzo wakagadziriswa wezvinotendwa neNASA kuti Mars yakaita sei. Denga repasi rine ruvara rwebhuruu nemhaka yechiitiko chinozivikanwa sekupararira kwaRayleigh, umo zvikamu zvechiedza chebhuruu zvinoparadzirwa mumhepo yakapoteredza pasi. PaMars, zvinopesana zvinoitika. Guruva riri mumhepo rinoparadzira zvikamu zvitsvuku zvechiedza, rinoita kuti denga riite seritsvuku. NASA inotaura kuti denga rakaratidzika kuva rebhuruu nemhaka yokuti mifananidzo yakacheneswa yeViking yakanga ichiri kufanira kuenzaniswa nechiyero chakarurama chemavara. Kurukurirano yacho yave ichitsviriridza chibviro cha 1970 apo Viking 1 yekumhara yeNASA yakava ngarava yokutanga yokudenga kusvika papuraneti tsvuku, mukuwirirana nomushumo waAlan Boyle muNBC News. Mifananidzo yaro yokutanga yakaratidza zvairatidzika kuva denga rebhuruu, rakafanana nerinoonwa paPasi, kuchisimudzira tariro yokuti kungava noupenyu paMars. Mumwe mutezo wechikwata cheViking Carl Sagan akazivisa pamusangano wenhau nokukurumidza pashure pacho kuti: Pasinei zvapo nepfungwa iri mumifananidzo iyi, denga harisi rebhuruu...Denga chaizvoizvo rine ruvara rweruvara rweruvara rweruvara rwer Denga repasi rine ruvara rwebhuruu nemhaka yechiitiko chinozivikanwa sekupararira kwaRayleigh, umo zvikamu zvechiedza chebhuruu zvinoparadzirwa mumhepo yakapoteredza pasi. PaMars, zvinopesana zvinoitika. Guruva riri mumhepo rinoparadzira zvikamu zvitsvuku zvechiedza, rinoita kuti dengawo riite seritsvuku. NASA inotaura kuti denga rakaoneka riri rebhuruu mumifananidzo yokutanga yeMars...  <response>: Muna 1976 Viking 1 yeNASA yakadzorera mufananidzo weMars nedenga rebhuruu. NASA yakataura kuti mufananidzo wacho wakanga uchiri kufanira kuyerwa nechiyero chemavara chakakodzera. Vamwe vanodzidzisa nezvokurangana vakabvunza nzira dzokuyera dzeNASA. NASA inobvuma kuti haisi sayenzi chaiyo uye inowanzoshandisa shanduro dzakasiyana.
