Selection of payload items


Tokyo—Space BD, a leading Japanese space startup, would like to announce the third round of the Space Delivery Project “RETURN to EARTH,” a space use project. Payload items from research centers, educational institutions, and private sector companies located in Japan and abroad have been decided on, and these items are planned to be launched to the International Space Station (ISS) on the SpaceX Falcon 9 rocket in early November 2023. In addition to items for research & development use as well as promotional use that were among the payload items in the first and second rounds, in this third round there are new food and D&I promotion projects. The winning idea from a business contest is also planned to be launched into outer space. The payload items in this third round are planned to be loaded into the Exposed Facility platform device on the ISS and spend approx. 6 months exposed to space, after which they will be returned to Earth in summer 2024 on a resupply mission and returned to their origin around autumn 2024.


Upcoming schedule 

10th November 2023                                    Loaded on to SpaceX Falcon 9 rocket & launched

November 2023 – Around summer 2024             Payload items exposed to space for approx. 6 months on the ISS Exposed Facility platform, and then returned to Earth on a resupply mission

Space BD is calling any customer who is interested in research & development, company branding, or marketing activities that make use of space. If you are interested please contact us at



 Space Delivery Project “RETURN to EARTH”

This project makes use of the small simple exposure experiment device (ExBAS*) installed in the medium exposure experiment adapter (i-SEEP) of the ISS Kibo. Space BD called for participation among a wide range of organizations and is providing a variety of support, including payload item selection, launch, and the return to Earth.

*About ExBAS

As a user of i-SEEP, Space BD has jointly developed ExBAS in collaboration with JAXA since 2020. The use of ExBAS enables Space BD to provide future services for exposure of materials, etc. to space. In addition to the conventional uses of space for research purposes, Space BD hopes to broaden the horizons for the use of space by encouraging a wider range of more general use.





Comment from Hoshiko Nakata, Business Development / Engineer, Space BD

I was so excited to hear the news that the payload items in this third round of the Space Delivery Project “RETURN to EARTH” are ready for launch. We have expanded the use of space with the payload items in this third round beyond what was achieved in the first and second rounds. This achievement was made possible with the great creativity and effort of the teams at JAXA and NASA, as well as from our collaboration partner companies. Thank you all very much. We have a variety of plans underway for once the payload items are back on Earth to deliver new possibilities for the use of space to all of you, and we hope you will keep an eye out for more news on these initiatives.


Space Delivery Project “RETURN to EARTH” Third Round Participating Companies and Organizations

Oita Prefecture

“Space Letterpress Printing Project” (Toshihiro Katayama, Takeshi Kimoto, Yuji Tokuda, Mayuki Nishijima)


~The Future of Space and Earth~

Comment from Takeshi Kimoto, Member of the Space Letterpress Printing Project

This project began with the Oita Prefecture “Space Business Talent Training Seminar,” and now the project is sending a piece of letterpress printing, one of the three great inventions of the world, into space.   The relationship of space and Earth was carved as a symbol into this item, with the keyword “harmonious cycle.” After the return to Earth the project intends to create a work of art using this piece of printing and make our shared vision a reality.

Aluminum plate printed with the Kyushu Institute of Technology logo and the wishes of the students

Comment from Minoru Iwata, Associate Professor, Department of Space Systems Engineering, School of Engineering, Kyushu Institute of Technology

I would like to express our gratitude for everyone’s support and cooperation that enabled us to have this opportunity. The Iwata Laboratory (Extreme Environment Materials Laboratory) is conducting research activities to energize the space industry through research, development, and demonstrations focusing on the environmental degradation of materials used in space. In my view, many people still do not know that materials degrade in the harsh environment of space. I hope that seeing the plate returned from space will make the students of the Kyushu Institute of Technology and other people in the community feel more of an affinity to space development, and that they will become interested in space development and material degradation in the space environment. We will continue to push forward in our research activities so that we can keep on developing initiatives to energize the space industry through the development and demonstration of new technologies.
