Спутник ФКИ. Double Star 2. [Редактировать]

Аппарат изготовлен государственной компанией Aerospace Dongfanghong Satellite Ltd. Имеет форму цилиндра диаметром 2.1 м и высотой 1.4 м, а вместе с антеннами и штангами научной аппаратуры аппарат достигает 4 м в высоту и 8.3 м в поперечном направлении.

Научные задачи аппарата:

  • исследование магнитного пересоединения на магнитопаузе и в магнитном хвосте магнитосферы;
  • достижение понимания и проведение поиска места «спускового механизма» магнитосферных бурь и суббурь;
  • изучение физических процессов в магнитосфере, таких как ускорение частиц, диффузия, инжекция и выброс вверх ионов из ионосферы во время магнитных бурь;
  • изучение временных вариаций в системе токов, текущих вдоль силовых линиймагнитного поля Земли и взаимосвязи между токами хвоста магнитосферы и токами в зонеполярных сияний на уровне ионосферы.

Состав бортового оборудования:

  • NUADU (Neutral Atom Detection Unit) - блок для исследования энергетически нейтральных атомов, образованных в результате столкновения энергетических ионов с холодными нейтральными атомами.
  • FGM (FluxGate Magnetometer) - шлюзовой магнитометр, смонтированный на штанге длиной 3,5 м.
  • PEACE (Plasma Electron And Current Experiment) – прибор предназначен для определения концентраций электронов с низкими и сред-ними энергетическими уровнями путем замера числа столкновений электронов на каждом энергетическом уровне и в любом направлении.
  • LEAD (Low Energy Ion Detector) – детектор предназначен для изучения ионов с низким энергетическим уровнем. LFEW (Low Frequency Electromagnetic Wave Detector) – детектор низкочастотных электромагнитных волн.
  • HEED (High Energy Electron Detector) – детектор обнаружения высокоэнергетических электро-нов.
  • HEPT (High Energy Proton Detector) – детектор обнаружения высокоэнергетических протонов.
  • HID (Heavy Ion Detector)- детектор регистрации ионов
