Title : Challenge to the Space: IMOFF (Ionosphere/Magnetosphere Observation with Formation Flying) Mission
 

Abstract :

The ionospheric and magnetospheric disturbances caused by energy deposition from the solar wind appear in a variety of scale sizes. For example, it is known that charged particle precipitation has a scale size of several tens of km while auroral brightening appears over a wide longitudinal scale on the aurora oval and its effect to the ionosphere is a global scale phenomenon. For the study of ionospheric and magnetospheric storms with complex structures, multi-point observations have been demanded in the space physics community. For this purpose, KASI (Korea Astronomy and Space Science Institute) has a plan to launch a new mission that consists of one small satellite (mother sat) of 100 kg and four nanosats (daughter sats) of 3 kg. These four nanosats will be deployed on orbit and separated from the mother sat slowly and reach 100 km distance after 1 year. The mother sat has optical instruments and a new particle detector package covering wide energy range while the daughter sats have simple particle detectors and magnetometers. With this mission, we can study multi-scale structures of the ionosphere and magnetosphere in a low earth orbit. This mission will be developed by a domestic and international collaboration.
