Idatha ebonelelwe ngaphezulu kweminyaka elishumi ziisathelayithi ezimbini zokubeka iliso eMhlabeni ezisungulwe yi NASA iqinisekisa into esele siyazi ixesha elithile. Imvula yehlile kwi Amazon, ebangela ukulahleka kwezityalo. Ukugcina kancinci nekhabhoni, ihlathi lemvula laseAmazon linegalelo kushushu lwehlabathi, ekufanele ukuba liqhubeke ukunciphisa imvula kwingingqi.
Ukoyiswa kwe space Ngamanye amaxesha kuboniswa njengokukhangela okungenamsebenzi, ukutya oovimba abakhulu bezoqoqosho. Ayikho enye into ebubuxoki, okokuqala kuba ikhubazekile ibalulekile uphuhliso ubuchwepheshe, Kwaye nangenxa yokuba ivumele ukusekwa kwenethiwekhi ye othungelwano ibaluleke kakhulu kwilali yehlabathi. Okokugqibela, iisathelayithi ezijikelezayo ukubeka esweni impilo ye Umhlaba Benze ukuba kube nakho ukuqikelela izoyikiso zoluntu.
Abaphandi basebenzise idatha eqokelelwe ziisathelayithi ezimbini, iTerra kunye neAqua. Terra (I-EOS AM-1) ikhutshwe yi NASA kumjikelezo ohambelana nelanga ngoDisemba 18, 1999 kwaye waqala ukuthatha imilinganiselo ngoFebruwari 24, 2000. The Aqua (EOS / PM-1), enye isathelayithi ye-NASA yophando lwenzululwazi, ibise-orbit ukusukela ngo-2002. Injongo yayo ijolise ikakhulu kufundo lomjikelo wamanzi, oko kukuthi imvula nenkqubo yomphunga. Esinye sezihloko ezifundwe kusetyenziswa zombini izixhobo bubudlelwane phakathi kotshintsho kwimvula kwi IAmazon kumgangatho wayo.
