WASEDA-SAT3 Mission movie

Extend and unfold the drag chute

Deployment of membrane by shape memory alloy After launching and effusing, we extend the membrane to use shape memory alloy. Shape of membrane is hexagon and it is folded with spiral folding

Let down the altitude of orbit by using drag chute

Evaluate deorbit system of deployment system We evaluate the system of deorbit by friction between air and deployment membrane. We prospect that increasing air friction by increacing surface area by membrane. This system protects that this satellite becomes space debris.
