Vesm\u00edrna sonda BepiColombo, ktor\u00e1 od roku 2018 putuje k\u00a0Merk\u00faru, sa dnes pribl\u00ed\u017eila k Venu\u0161i na vzdialenos\u0165 10 720 kilometrov. V\u010faka vedcom zo Slovenskej akad\u00e9mie vied bude mo\u017en\u00e9 tento bl\u00edzky prelet vyu\u017ei\u0165 na sk\u00famanie vlastnost\u00ed i\u00f3nov v jej hornej atmosf\u00e9re.<\/b><\/p>\n
Eur\u00f3psko-japonsk\u00e1 vesm\u00edrna sonda BepiColombo, ktor\u00e1 v roku 2025 dosiahne orbitu Merk\u00fara, transportuje viacero vedeck\u00fdch zariaden\u00ed. Tie bud\u00fa po\u010das najbli\u017e\u0161\u00edch \u0161tyroch dn\u00ed aktivovan\u00e9. Medzi nimi je aj i\u00f3nov\u00fd hmotnostn\u00fd spektrometer SERENA\/PICAM (Planetary Ion CAMera), ku kon\u0161trukcii ktor\u00e9ho prispeli aj vedci z \u00dastavu experiment\u00e1lnej fyziky SAV v\u00a0Ko\u0161iciach a\u00a0bratislavskej technologickej firmy Q-Products.<\/p>\n
\u201e\u00dalohou pr\u00edstroja PICAM je registrova\u0165 distrib\u00faciu i\u00f3nov, \u010di\u017ee ich chemick\u00e9 zlo\u017eenie, energiu a\u00a0smer, z\u00a0ktor\u00e9ho prilietaj\u00fa. Na rozdiel od na\u0161ej Zeme, ktor\u00fa pred slne\u010dn\u00fdm vetrom chr\u00e1ni jej magnetick\u00e9 pole, Venu\u0161a vlastn\u00e9 magnetick\u00e9 pole nem\u00e1. Jej magnetosf\u00e9ra je iba indukovan\u00e1 magnetick\u00fdm po\u013eom Slnka a\u00a0jej horn\u00e1 atmosf\u00e9ra v\u00fdznamne reaguje s\u00a0nabit\u00fdmi \u010dasticami slne\u010dn\u00e9ho vetra. Prelet sondy t\u00fdmto zlo\u017eit\u00fdm fyzik\u00e1lnym prostred\u00edm ur\u010dite prinesie mno\u017estvo cenn\u00fdch poznatkov o\u00a0tejto na\u0161ej susednej plan\u00e9te,\u201c<\/i>\u00a0uviedol J\u00e1n Bal\u00e1\u017e z\u00a0\u00daEF SAV,\u00a0 ktor\u00fd sa na kon\u0161trukcii sondy priamo podie\u013eal.<\/p>\n
