Спутник технологический. Sloshsat. [Редактировать]

Технологический космический аппарат разработанный Нидерландами.
Главные цели полета SloshSat:

  • получение данных для проверки существующих аналитических и цифровых моделей динамики жидкости в невесомости;
  • создание и испытание на орбите дешевой платформы для микроспутников, отвечающих требованиям безопасности для запуска с борта американских шаттлов. Полученные данные предполагалось использовать в целях: моделирования капиллярных эффектов в невесомости, уточнения существующих программ для расчета динамики жидкости (CFD), дальнейшего развития моделей, которые могут применяться в алгоритмах управления КА, сбора информации для проектирования систем управления жидкостью в невесомости.
