Спутник ФКИ. LISA pathfinder. [Редактировать]

LISA Pathfinder это демострационная миссия которая проводится ЕКА (ранее в миссии участвовало также НАСА). В рамках данного проекта космическое агентство планирует проверить существование гравитационных волн. 

С целью решения этой задачи планируется вывести на орбиту три аппарата которые образуют на орбите треугольник с длинной стороны 5 млн. км. Данная конфигурация орбитальной группировки позволит путем лазерного измерения расстояния между аппаратами оценивать искажение пространства которые эти волны могут вызывать. Также на аппарате будут проводиться измерения расстояния до золотых брусков которые расположенны внутри аппарата. Т.е. фактически своему устройству каждый из аппаратов LISA Pathfinder представляет полноценную "треть" LISA, которая связывается не с двумя частями лазерного "треугольника" на расстоянии в 5 миллионов километров, а фактически сама с собой, в результате чего лучи лазера будут проходить всего 38 сантиметров.

Первоначально запуск планировался на 2008 год, но был перенесен на 2015.

12016-03-03. NASA заключила контракт с Busek.
Космическое агентство США выбрала двигательную установку компании Busek для установки на свои CubeSat. Размер контракта на поставку BET-100 составил 1.6 млн. долл. (с возможностью увеличения размера до 2.3 млн. долл.).
Двигательные установки компании Busek относятся к классу микродвигательных установок, которые, тем не менее, позволяют достичь достаточно высокого уровня маневренности космических аппаратов. При этом, ранее компания уже поставляла свои электроспреевые установки для европейского космического аппарата LISA Pathfinder. Тэги: Космическое агентство СШАLISA pathfinder
22016-03-08. Airbus Defence and Space передала управление аппаратом LISA Pathfinder Европейскому космическому агентству.
Космический аппарат LISA Pathfinder успешно прошел этап орбитального тестирования и был передан на управление Европейскому космическому агентству (ЕКА). В настоящее время космический аппарат находится в точке Лагранжа L1(1,5 млн. км. от Земли) и успешно использует свои ускорители для обеспечения условий проведения эксперимента по поиску гравитационных волн.
В рамках проекта английское подразделение Airbus Defence and Space являлось головным разработчиком аппарата и двигательных установок, а немецкое подразделение отвечало за полезную нагрузку.Тэги: LISA pathfinderAirbus GroupЕвропейское космическое агентство
32016-06-07. ЕКА обнародовало данные о ходе работ с Lisa Pathfnder.
Европейские Ученые высказали полную удовлетворенность запущенным технологическим демонстратором Lisa Pathfinder и отметили, что если все пойдет и дальше успешно, то до 2034 году они бы хотели иметь на орбите полномасштабную версию обсерватории гравитационных волн. В Европейском космическом агентстве по этому поводу отметили, что они полностью согласны с учеными и действительно выбрали этот проект в качестве одного из приоритетов. Вместе с тем, агентство также отметило что в текущих условиях реализация подобного проекта может столкнуться с беспрецендентными сложностями в части необходимости достижения стабильности всех трех аппаратов на орбите, что может быть недостижимо ранее 2029 года. При этом, только на предварительное решение данного вопроса у агентства должно будет уйти около 3-4 лет, а сама разработка системы должна будет занять около 10-лет. Текущий же демонстратор хотя и стоил около 503 млн. долл., тем не менее имеет срок жизни около шести месяцев, из которых первые три уйдут на проверку пригодности выбранных технологических решений к решению задачи поиска гравитационных волн. А кроме того, при помощи одного аппарата найти гравитационные волны может оказаться затруднительно поскольку он имеет весьма малые габариты. Относительно возможной международной кооперации по данному проекту, то ЕКА в первую очередь рассчитывает на помощь НАСА.Тэги: LISA pathfinderЕвропейское космическое агентство
