Tokyo—Space BD, a leading Japanese space startup, announces the deployment of the CubeSat OPTIMAL-1 into space from the Japanese experimental module Kibo on the International Space Station (ISS) at 6 pm (JST) on Friday, January 6, 2023. Space BD provided all support for the deployment of the OPTIMAL-1, which was developed by ArkEdge Space Inc., Pale Blue Inc., Seiren Co., Ltd., the University of Fukui, the School of Engineering at the University of Tokyo, and Mitsubishi Electric Corporation.

OPTIMAL-1 was carried to the ISS on November 27, 2022 from the Kennedy Space Center in Florida aboard the SpaceX Crew Dragon resupply ship as part of NASA's 26th Commercial Resupply Service mission (CRS-26).
The deployment on January 6 was prepared by astronaut Koichi Wakata, who is currently aboard the ISS. OPTIMAL-1 has already successfully communicated with ground stations, and various demonstrations are planned for the future, including a nano-propulsion system, communication device, and on-orbit advanced information processing technology. “I was honored to work together with the satellite developers on this project” Tetsuro Mizuno, Senior Engineer at Space BD says, “to carry a satellite equipped with a propulsion system from the manned ISS has a more stringent NASA review process to ensure the safety of the astronauts. We came together to overcome each of the difficulties we faced to arrive at this successful deployment.”


■About OPTIMAL-1

OPTIMAL-1 is a multi-mission satellite that will improve and demonstrate further enhancements to the 3U general-purpose bus capabilities that ArkEdge Space demonstrated in orbit in 2018, as well as its main mission of technical demonstrations of (1) a nano water propulsion system, (2) edge computing, (3) a nano-hyperspectral camera, and (4) Store and Forward LoRa Low Power Communications, etc.
Future contribution is expected for forest management, agriculture, disaster prevention, logistics, and communications, etc. around the world.
