Спутник ФКИ. LADEE. [Редактировать]

LADEE это автоматическая миссия отправленная НАСА на Лунную орбиту для сбора информации о Лунной атмосфере и условиях на поверхности.

Аппарат конструктивно состоит из:

  • спутниковая платформа;
  • модуль дооснащения; 
  • модуль полезной нагрузки PLM. 

Отличительной особенностью конструкции является модульная схема компоновки. Аппарат, по сути, представляет собой несколько дисков, нанизанных на общий стержень. В основе конструкции лежит общая шина, по которой происходит распределение электроэнергии, там же находится общий канал обмена данными; каждый диск может нести те приборы и устройства, которые нужны для решения конкретной задачи. Такие сборные зонды могут стать намного дешевле, поскольку заказчик будет каждый раз собирать их из стандартных блоков, а не разрабатывать аппарат для конкретной задачи с нуля. 

Основные научные приборы аппарата: 

  • масс-спектрометр нейтральных частиц NMS (Neutral Mass Spectrometer) массой 11,3 кг и габаритами 43х25х37 см. Основное предназначение спектрометра NMS заключается в его использовании для исследования на предмет наличия благородных газов в атмосфере Луны, которые могли бы свидетельствовать о физических процессах, происходящих на Луне, и осуществить измерение уже ионизированных образцов;
  • датчик пыли LDEX (Lunar Dust Experiment), который даст возможность выявлять частицы до 1 мк в диаметре. Масса датчика – 3,5 кг, габариты – 15х15х20 см;
  • UVS спектрометр, работающий в УФ/видимой области спектра. В состав UVS спектрометра входят два телескопа и спектрометр. Один из телескопов – Limb Telescope (для наблюдений лимба небесного тела) – будет использован в целях изучения лимба Луны при прохождении линии терминатора или в полдень по местному времени. Второй телескоп – SOV (Solar Occultation Viewer) – будет направлен к Солнцу для поиска изменений в потоке солнечного излучения, вызванных частицами космической пыли во время прохождения света через лунную атмосферу. Спектрометр предназначен для работы в ближней ИК, видимой, а также средней УФ-областях спектра (в диапазоне волн между 0,23 и 0,81 мк). Спектроскопические данные позволят ученым исследовать состав лунной атмосферы и наблюдаемых частиц космической пыли. Ожидается, что с помощью прибора можно будет выявить ионизированные молекулы воды в атмосфере Луны;
  • LLCD (Lunar Laser Communications Demonstration) для осуществления эксперимента по увеличению скорости передачи данных с аппарата на Землю.

12013-10-24. Инженеры NASA сообщили об успешно проведенном эксперименте по созданию лазерной линии связи между Землей и космическим аппаратом LADEE. В ходе этого опыта были достигнуты рекордные показатели: передача данных на Землю осуществлялась со скоростью до 622 мегабит в секунду.Тэги: LADEE
22014-02-04. НАСА продлило работу зонда LADEE на лунной орбите на 28 дней, это позволит снизить орбиту зонда до нескольких километров над лунной поверхностью и собрать еще больше научных данных. "Запуск аппарата и выход на орбиту с использованием двигателей на борту LADEE были исключительно точны, поэтому у него осталось значительное количество топлива, что позволяет провести дополнительные исследования. Продление работы намного увеличит количество научных данных, которые даст этот проект", — пояснил менеджер проекта Butler Hine.Тэги: LADEE
