Poyasnenie: Pochti 400 let nazad astronom Iogann Kepler nablyudal hvosty komet, voznikayushie ot vozdeistviya solnechnogo vetra, i predpolozhil chto korabli mogut plavat' v kosmose, ispol'zuya parusa sootvetstvuyushei formy. Seichas izvestno, chto solnechnyi svet deistvitel'no sozdaet silu, kotoraya otklonyaet hvosty komet, i bol'shoi otrazhayushii svet parus mozhno primenit' dlya privedeniya kosmicheskogo korablya v dvizhenie. Privedennaya vyshe illyustraciya pokazyvaet odnu iz idei, razrabatyvaemyh NASA: sozdanie mezhzvezdnogo zonda, privodimogo v dvizhenie solnechnym svetom, otrazhennym ot sverhtonkogo parusa. Imeyushii v shirinu pochti polkilometra, hrupkii solnechnyi parus mozhet byt' raskryt v kosmose. Postoyannoe davlenie solnechnogo sveta uskorit apparat do skorosti, v pyat' raz prevoshodyashei vozmozhnuyu dlya obychnyh raket - i bez rashoda topliva! Esli zapustit' takoi zond v 2010 g., to uzhe v 2018 g. on obgonit Voyadzher 1, samyi dalekii iz kosmicheskih appartov, otpravivshihsya v mezhzvezdnoe prostranstvo, proletev za 8 let rasstoyanie, na kotoroe Voyadzheru ponadobilsya 41 god.
