6 CubeSats to be deployed from the “Kibo” Japanese Experiment Module on Tuesday, February 3, 2026

Experiment at Kibo

The following 6 CubeSats will be deployed from the “Kibo” Japanese Experiment Module as J-SSOD#35.

Gxiba-1^*1
CoRAL^*3
KNACKSAT-2^*2
HMU-SAT2(Teruteru)^*3
UiTMSAT-2^*2
LEOPARD^*3

*1 Deployed under the framework of the JAXA/UNOOSA collaboration "KiboCUBE" program.
*2 Deployed under the framework of the J-CUBE program, in which a CubeSat deployment opportunity is established through an agreement between JAXA and the University Space Engineering Consortium (UNISEC).
*3 Deployed under the J-SSOD service provider. 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 J-SSOD service provider:.
Selection of Service Provider for Small Satellite Deployment from Kibo

The deployment event for these satellites will be broadcast via YouTube JAXA Channel.

February 3, 2026 (Tuesday)
* The date and time of the deployment are subject to change due to the ISS schedule modification.

【Satellite】	Gxiba-1 [Size: 1U]
【Organizations】	Universidad Popular Autónoma del Estado de Puebla (UPAEP)
【Program】	KiboCUBE
【Mission】	To take pictures of Mexican active volcanoes from space, primarily Popocatépetl, a volcano located near Mexico City and Puebla. This satellite is a proof of concept to send a CubeSat constellation in the future to vectorize the ashes erupted by the volcanoes. Data from space will be downloaded by the Iridium Constellation and the UHF amateur band.
