Poyasnenie: Vopros: Chto iz sdelannogo lyud'mi nahoditsya na rasstoyanii 7,3 milliarda mil' (11,7 milliarda kilometrov)? Otvet: Stanciya "Pioner-10". V 1997 godu otmechalos' dvadcat' pyat' let s momenta ee zapuska. Nahodyas' ot Zemli na rasstoyanii 11 svetovyh chasov "Pioner-10" teper' vdvoe dal'she ot Solnca, chem Pluton, i so skorost'yu 45 tysyach kilometrov v chas (12,5 km/s) prodolzhaet udalyaetsya v mezhzvezdnoe prostranstvo. Chest' byt' pervym chelovecheskim ob'ektom, pokinuvshim predely orbit izvestnyh planet Solnechnoi sistemy — eto tol'ko odin iz punktov v dlinnom spiske dostizhenii etogo komicheskogo poslannika. V chastnosti, eto byl pervyi kosmicheskii apparat, peresekshii poyas asteroidov i issledovavshii vneshnie oblasti Solnechnoi sistemy, pervyi apparat, sblizivshiisya s Yupiterom i pervyi, ispol'zovavshii tyagotenie planety, dlya izmeneniya svoei traektorii i dostizheniya skorosti pokidaniya Solnechnoi sistemy. Missiya "Pionera-10" priblizhaetsya k koncu. Issleduya seichas otdalennye oblasti geliosfery, on skoro ischerpaet zapasy elektroenergii, neobhodimye dlya pitaniya nauchnyh priborov. No i posle etogo kosmicheskii apparat, massoi 570 funtov (230 kilogrammov) prodolzhit dvizhenie i cherez 30 tysyach let proidet primerno v 3 svetovyh godah ot zvezdy Ross 248 — slabogo krasnogo karlika v sozvezdii Telca, nahodyashegosya ot nas na rasstoyanii chut' bol'she 10 svetovyh let. (Primechanie: v 1998 godu "Voyadzher-1", zapushennyi pyat'yu godami pozzhe "Pionera-10", no dvigayushiisya bystree, stal naibolee otdalennym chelovecheskim kosmicheskim apparatom).
