\nRacheta lansatoare, care a avut 22 de etaje, a decolat de pe rampa de lansare la ora local\u0103 10.50, \u00een cea de-a treia misiune efectuat\u0103 \u00een mai pu\u0163in de dou\u0103 luni de SpaceX, o companie spa\u0163ial\u0103 privat\u0103, cu sediul \u00een California.<\/p>\n
\n\u00cen etajul plasat \u00een v\u00e2rful rachetei s-au aflat doi sateli\u0163i construi\u0163i de Boeing \u015fi de\u0163inu\u0163i de companiile Eutelsat Communications, care are sediul la Paris, \u015fi ABS, care are sediul \u00een Bermuda \u015fi este de\u0163inut\u0103 de grupul de investi\u0163ii european Permira.<\/p>\n
\nEutelsat Communications \u015fi ABS au \u00eemp\u0103r\u0163it costurile de fabrica\u0163ie \u015fi de lansare pentru cei doi sateli\u0163i.<\/p>\n
\nSateli\u0163ii lansa\u0163i duminic\u0103 sunt \u00eenzestra\u0163i cu motoare u\u015foare, integral electrice, spre deosebire de conven\u0163ionalele sisteme de propulsie folosite anterior, bazate pe reac\u0163ii chimice, folosite pentru plasarea \u015fi men\u0163inerea lor pe orbit\u0103.<\/p>\n
\nAcest detaliu a permis lansarea celor doi sateli\u0163i la bordul unei rachete purt\u0103toare Falcon 9, care are o dimensiune medie.<\/p>\n
\n“Valoarea propulsiei electrice const\u0103 \u00een faptul c\u0103 aceasta permite operarea unor sateli\u0163i care au nevoie de mult mai pu\u0163in combustibil dec\u00e2t sateli\u0163ii cu propulsie chimic\u0103. Astfel, po\u0163i s\u0103 ai sateli\u0163i mult mai u\u015fori \u015fi, \u00een teorie, costul lans\u0103rii este mult redus”, a precizat Michel de Rosen, directorul executiv de la Eutelsat Communications.<\/p>\n
\nCompania SpaceX, de\u0163inut\u0103 \u015fi operat\u0103 de antreprenorul miliardar Elon Musk, a reu\u015fit s\u0103 transforme principiul reducerii costurilor \u00eentr-o realitate \u015fi s\u0103 sparg\u0103 monopolul de\u0163inut de compania european\u0103 Arianespace pe pia\u0163a lans\u0103rilor de sateli\u0163i de dimensiuni mici.<\/p>\n
\nPotrivit site-ului companiei SpaceX, lansarea rachetelor din gama Falcon 9 cost\u0103 61 de milioane de dolari.<\/p>\n
\nDezavantajul propulsiei electrice const\u0103 \u00een faptul c\u0103 sateli\u0163ii vor avea nevoie de c\u00e2teva luni, \u00een loc de c\u00e2teva s\u0103pt\u0103m\u00e2ni, pentru a ajunge pe orbitele lor opera\u0163ionale, la circa 35.800 de kilometri deasupra Terrei.<\/p>\n
\nSatelitul operat de Eutelsat va deveni parte a unei re\u0163ele alc\u0103tuite din 35 de sateli\u0163i, care ofer\u0103 servicii de comunica\u0163ii \u00een domenii precum telefonia mobil\u0103, internet \u015fi transmisiuni video. Noul satelit va extinde aria de acoperire a companiei Eutelsat \u015fi asupra celor dou\u0103 Americi.<\/p>\n
\nABS, care opereaz\u0103 \u00een prezent \u015fase sateli\u0163i, \u00ee\u015fi va pozi\u0163iona noul satelit pentru a asigura servicii de telecomunica\u0163ii \u00een Europa, Africa \u015fi Orientul Mijlociu.<\/p>\n
\nCele dou\u0103 companii au \u00eencheiat deja un parteneriat pentru a lansa \u00eempreun\u0103 o alt\u0103 pereche de sateli\u0163i, tot cu o rachet\u0103 Falcon 9, \u00een a doua jum\u0103tate a acestui an.<\/p>\n
\nCompania SpaceX opereaz\u0103 de asemenea misiuni de tip cargo la bordul Sta\u0163iei Spa\u0163iale Interna\u0163ionale (ISS) pentru NASA \u015fi lucreaz\u0103 \u00een prezent la dezvoltarea unui vehicul spa\u0163ial care va fi capabil s\u0103 transporte \u015fi astronau\u0163i la bordul avanpostului orbital.<\/p>\n","protected":false},"excerpt":{"rendered":"
