Space Weather <\/a>a zatia\u013e ide o teoretick\u00fd koncept podporen\u00fd po\u010d\u00edta\u010dov\u00fdmi simul\u00e1ciami.<\/p>\n\u0160es\u0165 dru\u017e\u00edc by vytvorilo ak\u00fdsi \u201eairbag\u201c<\/p>\n
V\u00fdskumn\u00edci navrhuj\u00fa vysla\u0165 pribli\u017ene 36-tis\u00edc kilometrov nad Zem \u0161es\u0165 ve\u013ek\u00fdch dru\u017e\u00edc, pribli\u017ene ve\u013ekosti autobusu.<\/p>\n
Ak by sa k na\u0161ej plan\u00e9te bl\u00ed\u017eila siln\u00e1 slne\u010dn\u00e1 b\u00farka, satelity by vypustili sod\u00edk, b\u00e1rium, v\u00e1pnik a \u010fal\u0161ie plyny. Tie by vytvorili plazmov\u00fa vrstvu na okraji magnetosf\u00e9ry, ktor\u00e1 by \u010das\u0165 nabit\u00fdch \u010dast\u00edc odklonila alebo oslabila.<\/p>\n
Spoluautor \u0161t\u00fadie Daniel Welling prirovnal cel\u00fd syst\u00e9m k \u201eairbagu v magnetosf\u00e9re\u201c, ktor\u00fd by chr\u00e1nil Zem pred najhor\u0161\u00edmi d\u00f4sledkami slne\u010dn\u00fdch b\u00farok.<\/p>\n
Simul\u00e1cie dopadli prekvapivo dobre<\/p>\n
Vedci si koncept otestovali na po\u010d\u00edta\u010dov\u00fdch modeloch, ktor\u00e9 simulovali siln\u00fa geomagnetick\u00fa b\u00farku z m\u00e1ja 2024. T\u00e1 sp\u00f4sobila najv\u00fdraznej\u0161ie poruchy sp\u00f4soben\u00e9 slne\u010dnou aktivitou za viac ne\u017e dve desa\u0165ro\u010dia.<\/p>\n
Pod\u013ea v\u00fdsledkov by syst\u00e9m StormWall dok\u00e1zal zn\u00ed\u017ei\u0165 intenzitu geomagnetickej b\u00farky a\u017e o 84 percent.<\/p>\n
\u201eKe\u010f na tento probl\u00e9m pou\u017eijete naozaj seri\u00f3znu fyziku, zist\u00edte, \u017ee to funguje,\u201c povedal hlavn\u00fd autor \u0161t\u00fadie Brian Walsh.<\/p>\n
Superb\u00farka by mohla sp\u00f4sobi\u0165 bili\u00f3nov\u00e9 \u0161kody<\/p>\n
Slne\u010dn\u00e9 erupcie pravidelne vyvrhuj\u00fa do vesm\u00edru obrovsk\u00e9 oblaky nabit\u00fdch \u010dast\u00edc, zn\u00e1me ako koron\u00e1lne v\u00fdrony hmoty. V\u00e4\u010d\u0161ina z nich sp\u00f4sob\u00ed len pol\u00e1rnu \u017eiaru alebo kr\u00e1tkodob\u00e9 v\u00fdpadky r\u00e1diovej komunik\u00e1cie.<\/p>\n
Pribli\u017ene raz za sto rokov v\u0161ak m\u00f4\u017ee nasta\u0165 mimoriadne siln\u00e1 udalos\u0165, ktor\u00e1 by mohla po\u0161kodi\u0165 satelity, vyradi\u0165 elektrick\u00e9 siete \u010di naru\u0161i\u0165 internetov\u00fa komunik\u00e1ciu na rozsiahlych \u00fazemiach.<\/p>\n
Vedci odhaduj\u00fa, \u017ee \u0161kody pri takejto superb\u00farke by mohli dosiahnu\u0165 a\u017e 3,4 bili\u00f3na dol\u00e1rov.<\/p>\n
Zatia\u013e ide len o v\u00edziu<\/p>\n
Autori \u0161t\u00fadie prizn\u00e1vaj\u00fa, \u017ee realiz\u00e1cia projektu by bola mimoriadne n\u00e1kladn\u00e1. Satelity patriace do syst\u00e9mu StormWall by patrili medzi najv\u00e4\u010d\u0161ie, ak\u00e9 \u013eudstvo doteraz vypustilo do vesm\u00edru, pri\u010dom po ka\u017edom pou\u017eit\u00ed by ich bolo potrebn\u00e9 nahradi\u0165 nov\u00fdmi.<\/p>\n
Napriek tomu s\u00fa presved\u010den\u00ed, \u017ee invest\u00edcia by sa mohla vyplati\u0165.<\/p>\n
\u201e\u013dudia si v\u017edy mysleli, \u017ee vesm\u00edr je pr\u00edli\u0161 ve\u013ek\u00fd a my m\u00f4\u017eeme iba prij\u00edma\u0165 to, \u010do n\u00e1m Slnko priprav\u00ed. Zistili sme v\u0161ak, \u017ee situ\u00e1ciu vieme ovplyvni\u0165,\u201c povedal Walsh.<\/p>\n
Aj \u0161\u00e9f heliophysics v NASA David Sibeck pova\u017euje my\u0161lienku za zauj\u00edmav\u00fa. \u201eAk by som vedel, \u017ee sa bl\u00ed\u017ei storo\u010dn\u00e1 slne\u010dn\u00e1 superb\u00farka, ktor\u00e1 vyrad\u00ed elektrick\u00e9 siete, ur\u010dite by som tak\u00fdto syst\u00e9m chcel ma\u0165,\u201c uviedol.<\/p>\n","protected":false},"excerpt":{"rendered":"NEW YORK – Siln\u00e9 slne\u010dn\u00e9 b\u00farky m\u00f4\u017eu vyradi\u0165 satelity aj elektrick\u00e9 siete.
