RERA: Rubber balloon experiment for reentry capsule with thin-type aeroshell
We have conducted a free-flight atmospheric reentry capsule experiment using a rubber balloon, established a high-frequency demonstration platform for the experiment, and proposed a method to combine parameter and empirical research, which are inherently contradictory in nature.

On July 1, 2022, the first RERA-1 was released from the Taiki Aerospace Research Field, and at an altitude of 25 km, the capsule was separated and took a free flight. Coordinates, attitude, and image data were acquired as expected during flight.

Preparations are underway for another release in FY2023.
