Техника. STEREO A. [Редактировать]

STEREO (Solar TErrestrial RElations Observatory) — миссия НАСА по изучению солнечной активности. Два одинаковых космических аппарата были запущены 26 октября 2006 года на орбиты близкие к орбите движения Земли вокруг Солнца. В ходе проекта один из них постепенно отстает от Земли (Behind), а другой, наоборот, обгоняет её (Ahead). Это дает возможность одновременно наблюдать Солнце из двух разных точек, то есть использовать стереоскопический эффект, позволяющий получать трёхмерные изображения структур и явлений на Солнце. Одной из целей проекта является изучение корональных выбросов массы, и стереоскопический эффект позволяет определить положение источника выброса на Солнце и траекторию его движения, которые невозможно определить по одиночному наблюдению с помощью коронографа у Земли, как, например, в проекте SOHO. Такие наблюдения помимо того, что дают новые данные при изучении солнечной активности, способны существенно повысить точность прогнозов эффектов космической погоды и, в частности, геомагнитной активности.

12016-08-23. Агентству удалось восстановить связь с аппаратом.
Космическое агентство США объявило о том, что оно сумело впервые за два года установить связь с космическим аппаратом STEREO-B. При этом, устойчивая связь со спутником продолжалась несколько часов. По результатам работы инженеры агентства понизили напряжение энергосистемы аппарата, чтобы сэкономить электроэнергию.
Последний раз до этого с аппаратом удалось установить радиосвязь в 2014 году, а после этого, согласно сообщению агентства на нем отказала система ориентации.
Вторая обсерватория (STEREO A) работает штатно. Наличие двух аппаратов должно было позволить НАСА получать трехмерные изображения Солнца. Потере связи с аппаратом предшествовал тест системы управления. По замыслу создателей спутника он должен был осуществлять перезагрузку в случае если в течении 72 часов с ним не устанавливается связь с Земли.Тэги: STEREO BКосмическое агентство СШАSTEREO A
