The orbital velocity in the atmospheric entry in the deep space sample return reaches 15 km/s, which results in extremely severe aerodynamic heating to the sample return capsule (SRC). To reduce the severe heating environment by efficient aero-deceleration at high altitudes, a new concept of SRC with a lightweight and large-area aeroshell is proposed. The SRC is needed to be aerodynamically stable at all speeds because it is expected to be operated without a parachute in the atmospheric entry. To evaluate dynamic stability in attitude for capsule with thin aeroshell, the Rubber balloon Experiment for Reentry capsule with thin Aeroshell (RERA) was conducted on July 1st, 2022. The capsule with a mass of 1.56 kg and a diameter of 0.8 m was dropped from the balloon at an altitude of 25 km, and then, started the free flight. In operation, data measured by onboard sensors and photographs by a camera were successfully transmitted to the ground station. The capsule was in low oscillation in attitude without a vertical rotation. The flow field around the capsule during the operation was 0.15 in Mach number in maximum and an order of magnitude 10(exp 5) in Reynolds number. This indicated that the present experiment reproduced a flow field around the actual deep space SRC at low speed. Although the moment of inertia of the capsule for the present experiment was different from the actual SRC, it was suggested that the capsule was dynamically stable in the low-speed region.","subitem_description_type":"Other"}]},"item_3_description_18":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"形態:
