Спутник технологический. SOMP. [Редактировать]

SOMP (Students' Oxygen Measurement Project — Студенческий проект по измерению концентрации кислорода) — малый спутник форм-фактора CubeSat 1U, созданный студентами Дрезденского технического университета при поддержке Германского центра авиации и космонавтики.
Космический аппарат имеет две научные цели:

  • измерение концентрации атомарного кислорода в верхних слоях атмосферы с использованием электролитического датчика кислорода «FIPEX» (Flux/Phi Probe Experiment);
  • испытание гибких тонкопленочных солнечных элементов (TFSC — Thin Film Solar Cells).
