<prompt> Fingqa isihloko: Ukunyakaza okuhlaba umxhwele kwamasathelayithi ahlukahlukene azungeza iplanethi yethu kuye kwavezwa kuyi - video ehlaba umxhwele ye - NASA. Idalwe yi-Goddard Space Flight Centre yenhlangano eseMaryland, ibonisa yonke imikhumbi yabo yokubuka umhlaba nezindlela abahamba ngazo bezungeza umhlaba. Nakuba i - ISS ihamba ngokuphambene, okungenani kule video, abanye abanjenge - Landsat bayabonakala behamba besuka esigxotsheni beya esigxotsheni. Skrolela phansi ukuze ubone ividiyo. Ososayensi be-NASA eMaryland, eU.S. baye bakha ukubonwa kwesathelayithi okuboniswe lapha. Ibonisa inqwaba yezinkanyezi ezihlola umhlaba ezizungeza iplanethi yethu. Zihlanganisa iLandsat 7 no-8, ingxenye yochungechunge lwezinhlelo ze - NASA esezinesikhathi eside zisebenza. Futhi i - ISS ingabonakala futhi ihamba ngokuphambene nomhlaba. Le-animation ibonisa kuphela ama-satellite e-NASA abheka umhlaba, hhayi amanye aqhutshwa ezinye izinhlangano zesikhala noma izinhlangano ezizimele. La masathelayithi alinganisa imvula, imisebe yelanga, amafu, ukuphakama kolwandle, usawoti olwandle nezinye izici zemvelo yomhlaba. Zihlangene, zinikeza isithombe somhlaba njengohlelo, kusho iNASA. Isithombe sibonisa usuku lwangoFebhuwari 16, 2015 kusuka ngo-00:00 GMT kuya ku-12:00 GMT. Nakuba lezi zinkanyezi zingase zibonakale zisondelene kakhulu, isikhala esisemkhathini womhlaba sikhulu kakhulu, futhi mancane amathuba okuba zishayisane. Eqinisweni, zonke zibekwe emizileni ethile ngaphakathi kwamabhande azo okuzungeza okuqinisekisa ukuthi mancane amathuba okuba zishayisane nesinye isathelayithi. Nokho, akwenzeki ngaso sonke isikhathi njengokuhleliwe. Ngo-2009, isathelayithi yase-United States i-Iridium nesathelayithi yaseRussia eyayingasasebenzi i-Cosmos zashayisana, zakha amakhulu ezinsalela ezintsha emzileni. Kodwa ukunemba kwamasathelayithi anamuhla kubonakala kangcono ngequartet yamasathelayithi aziwa ngokuthi i - A-train - i - Aqua, i - Aura, i - CloudSat neCalypso - alandelana eduze emizileni yawo. Lezi ezimbili eziseduze kakhulu, i-Cloudsat neCalypso, zihlukaniswe amasekhondi angu-12.5 kuphela, kodwa lokhu kulingana namabanga angamakhilomitha angu-93. Lezi zinkanyezi ezine zisebenza ndawonye ukuze zinikeze ukubonwa okungcono kakhulu koMhlaba. Isebenza njengesathelayithi eyodwa enezinsiza eziyi-15 ezisebhodini, Ernie...  <response>: Ososayensi beNASA eMaryland, eU.S. baye bakha ukubonwa kwesathelayithi. Kubonisa inqwaba yezinkanyezi ezibuka umhlaba ezizungeza iplanethi yethu njengamanje. Zihilela iLandsat 7 no - 8, ingxenye yochungechunge lwezinhlelo ze - NASA esezinesikhathi eside zisebenza. Futhi i - ISS ingabonakala futhi ihamba ngokuphambene nomhlaba. Ama-satellite amaningi okubuka umhlaba azungeza i-pole to pole ukuze abone iplanethi yonke.
