Спутник ФКИ. Munin. [Редактировать]

Космически аппарат фундаментальных космических исследований разработанный в период с 1996 до 2000 гг. сотрудниками Шведского института космической физики и студентами университетов Умеа и Лулеа. Аппарат предназначен для изучения полярных сияний и «космической погоды» над Северным и Южным полушариями.  Система стабилизации аппарата основана на магнетометрах.

Основным научным прибором аппарата является комбинированный электронный и ионный спектрометр MEDUSA (Miniaturized Electrostatic Dual‑tophat Spherical Analyzer). Прибор был изготовлен  в Юго‑Западном исследовательском институте (США).  Прибор измеряет распределение электронов и ионов с энергиями до 17 кэВ на единицу заряда с временным разрешением 0.25 сек для электронов и 0.5 сек для ионов.

Дополнительной полезной нагрузкой аппарата выступает детектор ионов и нейтральных атомов DINA (Detector of Ions and Neutral Atoms).Данный твердотельный сенсор был разработан Институтом космической физики и регистрирует ионы с энергиями 20–1200 кэВ с помощью двух взаимно перпендикулярных детекторов.

Также на аппарате установлена ПЗС камера которая должна снимать северные сияния.
