Oamenii de \u0219tiin\u021b\u0103 de la NASA avertizeaz\u0103 c\u0103 explozia num\u0103rului de sateli\u021bi planifica\u021bi pentru lansare ar putea contamina aproape toate imaginile viitoare captate de telescoapele spa\u021biale, pun\u00e2nd \u00een pericol decenii de cercetare astronomic\u0103, scrie ScienceAlert<\/a>.<\/p>\n

Un studiu publicat \u00een revista Nature avertizeaz\u0103 c\u0103 lumina reflectat\u0103 de sateli\u021bii afla\u021bi pe orbit\u0103 risc\u0103 s\u0103 compromit\u0103 observa\u021biile telescoapelor care exploreaz\u0103 Universul \u00eendep\u0103rtat.<\/p>\n

Riscuri noi pentru telescoapele spa\u021biale<\/h2>\n

Num\u0103rul sateli\u021bilor afla\u021bi pe orbita joas\u0103 a P\u0103m\u00e2ntului a crescut de la aproximativ 2.000 la 15.000 din 2019, impulsionat \u00een mare parte de mega-constela\u021bii precum re\u021beaua Starlink a lui Elon Musk<\/a><\/span>.<\/p>\n

Potrivit studiului, dosarele depuse deja la autorit\u0103\u021bile interna\u021bionale indic\u0103 faptul c\u0103 p\u00e2n\u0103 la sf\u00e2r\u0219itul anilor 2030, aproximativ 560.000 de sateli\u021bi ar putea orbita P\u0103m\u00e2ntul, un scenariu pe care cercet\u0103torii NASA \u00eel descriu drept \u201eo amenin\u021bare foarte grav\u0103\u201d pentru imagistica \u0219tiin\u021bific\u0103.<\/p>\n

Simul\u0103rile indic\u0103 un impact major asupra telescoapelor spa\u021biale<\/h2>\n

Cercet\u0103torii au simulat impactul acestei viitoare popula\u021bii de sateli\u021bi asupra a patru telescoape spa\u021biale importante.<\/p>\n

Lumina reflectat\u0103 ar putea contamina 96% dintre imaginile realizate de misiunea SPHEREx a NASA, viitorul telescop ARRAKIHS al ESA \u0219i telescopul Xuntian pe care China inten\u021bioneaz\u0103 s\u0103 \u00eel lanseze.<\/p>\n

Chiar \u0219i Telescopul Spa\u021bial Hubble, cu c\u00e2mpul s\u0103u vizual mai \u00eengust, ar putea avea o treime din imagini afectate de urme luminoase ce seam\u0103n\u0103 cu asteroizi sau alte obiecte cosmice.<\/p>\n

Competi\u021bia \u00een domeniu amplific\u0103 problema<\/h2>\n

Studiul avertizeaz\u0103 c\u0103 sateli\u021bii de dimensiuni din ce \u00een ce mai mari, unii dep\u0103\u0219ind 100 de metri p\u0103tra\u021bi, sunt acum la fel de str\u0103lucitori ca cele mai luminoase stele de pe cer.<\/p>\n

Cererea tot mai mare de date pentru inteligen\u021ba artificial\u0103<\/a><\/span> \u0219i competi\u021bia dintre re\u021belele de internet prin satelit ar putea duce la modele viitoare de p\u00e2n\u0103 la 3.000 de metri p\u0103tra\u021bi, suficient de str\u0103lucitoare \u00eenc\u00e2t s\u0103 par\u0103 \u201ec\u00e2t o planet\u0103\u201d.<\/p>\n

Cercet\u0103torii afirm\u0103 c\u0103 furnizarea datelor precise despre pozi\u021bia \u0219i orientarea sateli\u021bilor ar putea ajuta astronomii, \u00eens\u0103 reducerea num\u0103rului de lans\u0103ri r\u0103m\u00e2ne solu\u021bia cea mai eficient\u0103.<\/p>\n","protected":false},"excerpt":{"rendered":"
