Poyasnenie: Na maksimal'noi moshnosti noveishii ionnyi dvigatel', ustanovlennyi na kosmicheskom apparate "Dip Speis-1", obespechivaet tyagu okolo 1/50 doli funta (primerno 8 gramm). Na Zemle etoi sily kak raz hvatilo by, chtoby uderzhat' na vesu gazetu. Odnako pitaemye ot solnechnyh batarei ionnye reaktivnye dvigatel'nye ustanovki mogut rabotat' nepreryvno. Dlya zadach dlitel'nyh kosmicheskih poletov oni, v konechnom schete, podhodyat luchshe, chem moshnye, no rabotayushie lish' korotkoe vremya i menee effektivnyh himicheskie raketnye dvigateli. Na snimke "Dip Speis-1" zapechatlen v sborochnom pomeshenii, slozhennaya panel' solnechnoi batarei pokoitsya na kruglom module ionnogo dvigatelya. Kosmicheskii apparat, osnashennyi eksperimental'nym programmnym obespecheniem dlya avtonomnoi raboty, uzhe uspeshno prodemonstriroval novuyu dvigatel'nuyu tehnologiyu, kogda v iyule 1999 goda sblizilsya s asteroidom 9969 Brail'. Poznee, v noyabre togo zhe goda, apparat edva ne byl poteryan iz-za otkaza shirokougol'noi navigacionnoi kamery. No inzhenery smogli pereprogrammirovat' navigacionnuyu sistemu tak, chtoby ona ispol'zovala druguyu bortovuyu kameru, i 28 iyunya 2000 ionnyi dvigatel' vnov' byl vklyuchen. Teper' priklyucheniya "Dip Speis-1" prodolzhayutsya. Vnov' orientiruyas' po zvezdam, on segodnya sblizhaetsya s periodicheskoi kometoi Borelli.
