The observation was performed as one of the summer activities of the 56th Japanese Antarctic Research Expedition (JARE-56, the leader: Professor Yoshifumi Nogi, NIPR).
Phoenix-S1, after launch from an observation site called "S17" on Antarctic continent ice sheet, climbed up being suspended under a rubber balloon while aerosol number density observation and sampling are performed.
After the natural burst of the balloon at an altitude of 23 km, the UAV descended by a parachute, then started gliding back to the surface autonomously by separating the parachute and retrieved at S17 successfully.
The maximum observation altitude this time is unprecedentedly high as the observation altitude using UAVs and even manned aircraft. This method is quite effective to retrieve observation apparatuses and aerosol samples from upper atmosphere easily at low cost.
