12016-12-21. Airbus изготовила модуль полезной нагрузки.
Серия космических аппаратов MetOp это орбитальная группировка метео-спутников, которая работает на полярной орбите высотой около 800 км. Первый из аппаратов (MetOp-A) данной серии был запущен 19 октября 2006 года, а второй (MetOp-B) 17 сентября 2012 года. Оба аппарата работают в штатном режиме. Вместе с тем, в соответствии с планом пусков, компания Airbus сегодня обнародовала данные о том, что она произвела 2.1 тонный модуль полезной нагрузки третьего космического данной серии (запуск КА должен состояться в 2018 году). В ближайшее время (шесть месяцев) модуль и установленная на него полезная нагрузка должны будут пройти этапы тестирования и отработки в ЕКА. Со стороны производителя в данной операции будут участвовать около 30 человек. После этого, модуль отправится на интеграцию с сервисным модулем аппарата. Тэги: METOP-CAirbus Group
