Спутник ДЗЗ. ADM-Aeolus. [Редактировать]

ADM-Aeolus создается для изучения атмосферы Земли. Для достижения данной цели аппарат будет измерять атмосферу, что позволит ученым строить сложные модели. Аппарат будет функционировать на низкой ССО. Ветер будет измеряться в направлении 90 градусов от траектории движения аппарата при прохождении через затемненные участки Земли.

12015-05-22. Превышение сроков создания и цены на работу по созданию 2-ух аппаратов ЕКА привело к изменению процедуры работы.
Массовое отставание в сроках создания и превышения в цене на создание двух космических аппаратов, оснащенных лидарами, привело ЕКА к необходимости изменения контракта. Данные изменения учитывают проблемы в создании приборов и сроки запуска космических аппаратов. Кроме этого, агентство сказало что утвердит окончательную стоимость работ только после поставки полезной нагрузки. Также в Европейское агентство решило пересчитать уровень зрелости используемых в аппарате технологий с целью определения проблемных мест в процессе разработки.
В рамках прежних контрактов:
1. Цена ADM-Aeolus установлена была в 2003 году в размере 330 млн. долл., новая цена составляет 450 млн. евро. Срок запуска составлял 2007 год, новая дата 2017 год.
2. Цена EarthCare установлена была в 2008 году в размере 263 млн. евро. Срок запуска составлял 2013 год, новая дата 2018 год.Тэги: Европейское космическое агентствоADM-AeolusEarthCARE
22016-09-09. ЕКА выбрала ракету Вега для запуска спутника в 2017 году.
Arianespace подписала контракт с Европейским космическим агентством на запуск космического аппарата ADM-Aeolus. ADM-Aeolus должен будет предоставить возможность глобального наблюдения за ветрами в атмосфере Земли. Масса аппарата составит около 1300-1400 кг и он будет запущен на солнечно-синхронную орбиту высотой 320 км. На космическом аппарате будет установлено три модуля которые позволят получать 3-Д профиль атмосферы (будет измеряться как аэрозоли, так и водяной пар и направление ветра).Тэги: ArianespaceВегаADM-AeolusЕвропейское космическое агентство
32017-01-23. Компания Airbus объявила о завершении работ над космическим аппаратом Aeolus.
Компания Airbus объявила об окончании работ на КА AEOLUS и о готовности к проведению этапа окончательного тестирования в Тулузе. Космический аппарат в итоге будет весить около 1700 кг и на нем будет установлен лазерный LIDAR (диаметр телескопа 1.5 метра), который будет использовать эффект Доплера для определения скорости и направления ветра.Тэги: ADM-AeolusAirbus Group
