Nas segodnyashnei illyustracii izobrazhen
sputnik NASA NanoParus-D — pervyi v mire
apparat na solnechnom paruse, letayushii na nizkoi okolozemnoi orbite. Etot ochen' tonkii parus ploshad'yu 10 kvadratnyh metrov
byl nakonec razvernut 20 yanvarya.
Kosmicheskoe puteshestvie pod parusami vsegda schitalos' chem-to iz
oblasti nauchnoi fantastiki. Odnako eta ideya
byla predlozhena eshe 400 let nazad astronomom Iogannom Keplerom. On nablyudal, kak kometnye
hvosty razduvayutsya solnechnym vetrom.
Sovremennye kosmicheskie apparaty na solnechnyh parusah, takie kak
NanoParus-D ili yaponskii mezhplanetnyi apparat IKAROS,
polagayutsya na nebol'shoe, no postoyannoe davlenie solnechnogo sveta
i ispol'zuyut ego kak tyaglovuyu silu.
NanoParus-D inogda mozhno budet legko uvidet' s Zemli nevooruzhennym glazom: vrashayas' vokrug planety, on budet periodicheski
otbrasyvat' na nee solnechnyi zaichik.
Nablyudateli uzhe gotovyatsya vstupit' v bor'bu po s'emkam sputnika NanoParus-D.
Fotografii s Zemli pomogut NASA nablyudat' za sputnikom do teh por, poka on ne voidet v atmosferu v aprele ili mae.
