3 CubeSats will be deployed from “Kibo” Japanese Experiment Module on Friday, October 10th, 2025.

Experiment at Kibo

On October 10, 2025, the following 3 CubeSats will be deployed from the Japanese Experiment Module (JEM) “Kibo”:

YOTSUBA-KULOVER^*
e-kagaku-1^*
BOTAN^*

* In May 2018, as a new step to enhance the commercial utilization of Kibo, JAXA selected Space BD Inc. and Mitsui Bussan Aerospace Co., Ltd. as the J-SSOD service provider.
Selection of Service Provider for Small Satellite Deployment from Kibo

The deployment event for those satellites by J-SSOD#33 will be broadcast via YouTube JAXA Channel.

October 10, 2025 (Friday)
* The date and time of the deployment are subject to change due to the ISS schedule modification.
* The exact streaming time and URL will be announced once confirmed.

【Satellite】	YOTSUBA-KULOVER [Size: 2U]
【Organizations】	Kyushu Institute of Technology
【Service Provider】	Space BD Inc.
【Mission】	Observation of geomagnetic micro-variations to estimate the three-dimensional current systems and their structures during geomagnetic storms and auroral substorms. Imaging of auroras using compact cameras, with analysis of temporal variations in brightness and morphological structures. Investigation of the correspondence between magnetospheric currents and auroral emissions through comparative analysis of magnetic field data and auroral imagery. Research and development of a low-magnetic deployable mechanism aimed at suppressing magnetic interference for high-precision satellite-based magnetic field observations.
