<prompt> Fingqa isihloko: Nakuba izwe lihlukene phakathi ngokuthi lokho kugqoka kungokuluhlaza okwesibhakabhaka nokumnyama, noma okumhlophe nokegolide, i - NASA iye yahileleka engxabanweni yayo yombala. Kulokhu impikiswano ihilela iMars okuthiwa iplanethi ebomvu abakholelwa emibonweni yenzondo abakholelwa ukuthi empeleni iluhlaza okwesibhakabhaka futhi iluhlaza. Bathi i-ejensi yezinkanyezi iye yashintsha umbala wezithombe ezivela eMars ukuze zibonakale zibomvu, ziphuzi futhi zipinki, kulokho abathi kuwumzamo wokufihla ukuphila emhlabeni. Skrolela phansi ukuze ubone ividiyo. Le mpikiswano ibilokhu iqhubeka kusukela ngawo-1970 lapho isikebhe i-Viking 1 ye-NASA yaba yisona sikebhe sasemkhathini sokuqala ukufika eplanethini ebomvu. Izithombe zayo zokuqala zembula lokho okwakubonakala sengathi isibhakabhaka esiluhlaza kwesokudla, kodwa empeleni i-NASA ithi iplanethi inesibhakabhaka esibomvuesithambile. Ngakwesobunxele kunesithombe esicutshungulwayo sokuthi iNASA ikholelwa ukuthi iMars ibukeka kanjani. Isibhakabhaka eMhlabeni siluhlaza okwesibhakabhaka ngenxa yesenzakalo esaziwa ngokuthi ukusakazeka kukaRayleigh, lapho izinhlayiya zokukhanya okuluhlaza okwesibhakabhaka zisakazwa khona umkhathi. KuyiMars, kwenzeka okuphambene. Uthuli olusemkhathini luhlakaza izinhlayiya ezibomvu zokukhanya, okwenza isibhakabhaka sibonakale sibomvu. I-NASA ithi isibhakabhaka sasibonakala siluhlaza ngoba izithombe ze-Viking ezazigcotshwe kwakusadingeka ukuba zilinganiswe ngokulinganisela okuhle kwemibala. Le mpikiswano ibilokhu iqhubeka kusukela ngawo-1970 lapho i-Viking 1 ye-NASA iba umkhumbi-mkhathi wokuqala ukufika eplanethini ebomvu, ngokombiko ka-Alan Boyle kuyi-NBC News. Izithombe zayo zokuqala zembula lokho okwakubonakala kuyisibhakabhaka esiluhlaza, esifana naleso esibonwa eMhlabeni, okuvusa amathemba okuthi kungase kube nokuphila eMars. Ilungu leqembu le-Viking uCarl Sagan wamemezela engqungqutheleni yabezindaba ngokushesha ngemva kwalokho: Naphezu kokubonakala kwalezi zithombe, isibhakabhaka asisiwona oluhlaza okwesibhakabhaka... Empeleni isibhakabhaka sipinki. Isibhakabhaka eMhlabeni siluhlaza okwesibhakabhaka ngenxa yesenzakalo esaziwa ngokuthi ukusakazeka kukaRayleigh, lapho izinhlayiya zokukhanya okuluhlaza okwesibhakabhaka zisakazwa khona umkhathi. KuyiMars, kwenzeka okuphambene. Uthuli olusemkhathini luhlakaza izinhlayiya ezibomvu zokukhanya, lwenza isibhakabhaka sibonakale sibomvu. I-NASA ithi isibhakabhaka sasibukeka siluhlaza ezithombeni zokuqala zaseMars...  <response>: Ngo-1976 i-Viking 1 ye-NASA yathumela isithombe se-Mars nesibhakabhaka esiluhlaza okwesibhakabhaka. AbakwaNASA bathi isithombe besisazohlolwa ukuze sibe nombala ofanele. Ezinye izazi zezinkolelo-mbono zokwakha uzungu ziye zazingabaza izindlela zokulinganisa ze - NASA. I - NASA iyavuma ukuthi akuyona isayensi eqondile futhi ngokuvamile isebenzisa izinhlobo ezihlukene.
