Poyasnenie: Pochti 400 let nazad astronom Iogann Kepler, nablyudaya komety, ponyal, chto ih hvosty otklonyayutsya pod deistviem solnechnogo sveta. On predpolozhil, chto mozhno sozdat' kosmicheskie korabli, kotorye budut peredvigat'sya v prostranstve pod parusami. Solnechnyi svet deistvitel'no okazyvaet davlenie na hvosty komet, v nastoyashee vremya eto yavlyaetsya priznannym faktom. Poetomu bol'shoi otrazhatel'nyi parus vpolne mozhet stat' dvizhushei siloi kosmicheskogo korablya. Na illyustracii vy vidite model' parusa, razrabotannogo NASA dlya mezhzvezdnogo zonda. Zond predpolagaetsya privodit' v dvizhenie pod deistviem solnechnogo sveta, kotoryi budet otrazhat'sya ot sverhtonkogo parusa. Hrupkii solnechnyi parus, razmerom v polkilometra, predpolagaetsya razvernut' v kosmose. Postoyannoe davlenie solnechnogo sveta budet vse vremya uskoryat' korabl', kotoryi smozhet razognat'sya do skorosti, v pyat' raz prevyshayushei skorost' obychnoi rakety. I eto - bez vsyakih zatrat topliva. Esli zapustit' v kosmos takoi zond v 2010 godu, on smozhet v 2018 godu dognat' Voyadzher-1, preodolev za 8 let rasstoyanie, kotoroe Voyadzher smozhet proiti tol'ko za 41 god. V nastoyashee vremya Voyadzher-1 yavlyaetsya samym udalennym ot Zemli kosmicheskim korablem, zapushennym v mezhzvezdnoe prostranstvo.
