MABE-2 (Mars Airplane Balloon Experiment Two)

MABE-2 is the acronym of Mars Airplane Balloon Experiment Two a development and research effort to study the aerodynamic design of a future plane aimed to fly in the martian atmosphere. The project is led by Japan Aerospace Exploration Agency (JAXA) with collaboration of scientists and technicians of Tohoku University, Kyushu University, Kanazawa Institute of Technology, Tokyo University, Tokyo Metropolitan University, Kanagawa University, Nihon University, Xenocross Aerospace Systems and Kanazawa University

To simulate a flight in the very thin atmosphere of the red planet, the test model is lifted to 36 km by a stratospheric balloon and released from that altitude. Thus, the model is able to acquire aerodynamic data during the gliding descent. This data will serve to improve the model and to incorporate the analysis results into future Mars probe airplane designs.

Balloon launched on: 7/26/2023 at 3:53 jst
Launch site: Multipurpose Aviation Research Field, Taiki-Cho, Hokkaido, Japan  
Balloon launched by: Institute of Space and Astronautical Science (ISAS) / Japan Aerospace Exploration Agency (JAXA)
Balloon manufacturer/size/composition: Zero Pressure Balloon model B100 100.000 m3
Flight identification number: B23-05
End of flight (L for landing time, W for last contact, otherwise termination time): 7/26/2023 at 7:14 jst
Balloon flight duration (F: time at float only, otherwise total flight time in d:days / h:hours or m:minutes - ): 2 h
Landing site: In the Pacific Ocean 40 km E of Taiki, Japan

The balloon was launched from the Taiki Aerospace Research Field at 3:53 Japan Standard Time (JST) on July 26, 2023. The balloon ascended at a speed of about 240 meters per second to reach 36 km of altitude 2 hours and 33 minutes after launched, while flying above the Pacific Ocean about 40 km east of the Taiki base. After that, at 6:28 JST, a radio-command was transmitted and the flight test aircraft was ejected from the gondola. The balloon and control equipment section were separated by radio command seven minutes later, slowly descending to the sea about 40 km east of the Taiki base to be recovered by ship about 7:14 JST.
