Спутник ФКИ. ROSAT. [Редактировать]

ROSAT – германская космическая рентгеновская обсерватория. Названа в честь Вильгельма Рентгена. Запуск состоялся 1 июня 1990 при помощи ракеты Дельта-2 с мыса Канаверал. Масса спутника составляет примерно 2.4 тонны. Обсерватория работала до 12 февраля 1999 Изначально аппарат был рассчитан на 18 месяцев работы, однако инженеры нашли способ бороться со "старением" инструментов, и в итоге ROSAT был отключен лишь в феврале 1999 года и дальнейший его полет был неуправляемым.

12011-10-23. Спутник окончил свое существование.
23 октября спутник вошел в плотные слои атмосферы. Зона падения спутника по данным ЦУП ЦНИИмаш приведена на рис 5.1. С учетом того, что внешние поверхности телескопа защищены от перегрева и воздействия жесткой солнечной радиации, при вхождении в плотные слои атмосферы большая его часть не сгорит. Ожидается, что поверхности достигнут 30 обломков массой 1,6 тонны.Тэги: ROSAT
