Lapho nje sihlala kwi-maelstrom lapho kubonakala sengathi wonke umuntu uqala ukukhathazeka ngezindlela abaxhumana ngazo nabanye, eshiya ngemuva izingqikithi eziphindaphindayo zokuthi enye indlela iphephe kunenye yini noma ngabe ezinye izinto ziyasihlola oHulumeni, namuhla Ngifuna siqhubekele phambili kancane, okusho ukuthi, zama ukuqonda ukuthi umuntu angaxhumana kanjani nophenyo oludlula namuhla emkhawulweni wendawo yonke eyaziwayo. Namuhla sizobona ukuthi i-ESA ixhumana kanjani namaphenyo ayo.
Kuleli qophelo, ake ucabange ukuthi unesibopho sezokuxhumana futhi udinga ukuxhumana nawo wonke ama-probe azohamba ngokushesha noma kamuva emkhathini futhi, vele, awukwazi ukukhokhela ukunethezeka kokulahlekelwa amaphakheji njengokungathi ukuxhumana nge-audiovisual kwelashwa. Into yokuqala okufanele uyenze, ucabanga ngaphezu kwakho konke ngokujikeleza komhlaba, ngukuthi faka ama-antenna emhlabeni wonke, esimweni esinjalo ihlukaniswe ngama-120º komunye nomunye. Ngale ndlela sithola, ngokwesibonelo, izakhiwo ze-ESA eCebreros (Spain), Malargüe (Argentina) naseNueva Norcia (Australia). Isibonelo esisodwa ebesingaba naso, yiqiniso, kulabo abafakwe yi-NASA abaseGoldstone (e-United States), eCanberra (e-Asutralia) naseRobledo de Chavela (eSpain).
Ububanzi obuhlukile kuya ngokuthi iphenyo likude kangakanani
Ngaphambi kokuqhubeka ngithanda ukucacisa iphuzu elibucayi kule ndaba, impela uma usubonile izithombe kwesinye isikhungo se-ESA eSpain uzobe uqaphela ukuthi kunezimpondo eziningana, lokhu kunencazelo elula kakhulu esebenza ukuchaza okuthile izici zalokhu kufakwa okufanayo futhi ukuthi kuya ngobubanzi bayo isetshenziselwa ukuqapha nokuxhumana ngamaseli ahamba esikhaleni esijulile, imvamisa anokunye Amamitha angu-35 ububanzi futhi kuneziteshi ezintathu kuphela zokuqapha emhlabeni, esisodwa esishiwo esigabeni esandulele yi-ESA ne-NASA, kanti ezinye, zinobubanzi be Amamitha angu-15, basebenzela ukuthunyelwa kwamaphenyi aseduze kakhulu neziphuphutheki. Njengemininingwane, akutshele ukuthi, isibonelo, i-ESA inezinye iziteshi eziyisithupha ezinikezelwe ukuqapha ama-probes aseduze.
Lapho sesinazo zonke izimpondo ezidingekayo ezifakwe ezindaweni ezinamasu emhlabeni jikelele, sekuyisikhathi sokwakha umthetho olandelwayo wokuxhuma nama-probes okuthi, ezimweni ezinhle kakhulu, ngaphezu kwamakhilomitha ayizigidi ezimbili ukusuka emhlabeni. Ngalokhu sidinga izakhiwo zamaselula ezinamandla okujikisa kunoma iyiphi indlela enesisindo esingaphezu kwamathani angama-620 ngomthamo owanele wokudlulisa amasiginali omsakazo afinyelela ku-20kW wamandla.
Ngokuphathelene nokwamukelwa, amasiginali avela kuma-probe noma ama-satellite, lapho efinyelela ku-antenna, akhonjiswa endaweni enkulu yokuqoqa futhi ayakhuliswa ukuze kamuva athunyelwe ochungechungeni lwezibuko zensimbi ezihlukanisayo ukuhlukanisa amasiginali. amasiginali omsakazo anamaza ama-2 no-40 GHz. Lapho izimpawu sezitholakele, zithunyelwa esikhungweni esiseDarmstadt (eJalimane) lapho i-telemetry ihlukaniswe khona nedatha yesayensi futhi, uma isiphethwe, ibuyiselwa ku-ESA.
Ngokwesitatimende somqondisi wesiteshi saseCebreros, ULionel hernandez:
Sinohlelo oluhlelwe kakhulu. Siyazi ukuthi manje sesiqedile ngeRosetta, mhlawumbe, nokuthi emahoreni amabili sizobe sesithuthela eMars Express. Konke lokhu kuzenzakalelayo ngokuphelele, asisebenzi lapha. Ithimba lisebenza kuphela esigabeni esibucayi semishini. Uma kungenjalo, konke kulawulwa ukude kusuka eJalimane. Konke kuzenzekelayo, i-antenna ihlelwe ngendlela yokuthi, ngaleso sikhathi, ikhombe iMars Express bese iyilandela amahora amahlanu.
Kancane kancane, wonke lawa mabhande wokuhambisa ayabuyekezwa ukuze, ngokuya ngomsebenzi, futhi ikakhulukazi unyaka wawo wokwethulwa, isivinini siphezulu kakhulu ngenxa yalokhu esinakho, isibonelo, IMars Express ama-retransmissions awo alandwa ngejubane le- Ama-228 Kbits / s ngenkathi isibonakude isikhala Euclid, uma seyethuliwe, ukuhanjiswa kulindeleke ukuthi kube seduze kwe- I-74 Mbit / s.
