Tokyo—Space BD, a leading Japanese space startup, announces the return to Earth of the payload items exposed to space in the Space Delivery Project “RETURN to EARTH.” Through this project payload items were launched to the International Space Station (ISS) in February 2022, exposed to space for 9 months, and have now been returned to Earth.

The payload items, after being launched into space, were affixed to the ISS exposed facility, where they were exposed to cosmic and ultraviolet rays while flying at approx. 7.9 km per second (approx. 28,000 km per hour), 400 km above ground. This is one orbit of the Earth in approx. 90 minutes, or approx. 16 orbits per day. This is the first return of payload items for this first round of the project, and the items showed significant changes in color.

On March 27, 2023, a ceremony celebrating the return of the payload items was held at the Tsukuba Space Center of the Japan Aerospace Exploration Agency (JAXA), with some of the project participating companies in attendance.



In the first round of the project, research materials, photographs, and illustrations, among other items, were gathered from research institutes, educational institutions, and private companies in Japan and internationally, and transported into space. In addition to academic use of space to date, this project contributed to creating use cases of a diverse array of potential uses of space, including for marketing, branding, and education.
The payload items now returned to Earth are expected to be used for a variety of purposes going forward according to the goals of the customers, including for research & development, education, and PR.



■Comment from Masataka Sato, Business Development, Space BD Inc.

This project, first begun in 2021, has now had all milestones completed, and I am thrilled that the payload items are now ready to be safely returned to our customers.
Among the participating and partner companies in this first round were those who had prior experience participating in space-related projects, and those for whom this was the first such project. In my view, the strength of this project is the ease of access to a space experience. Going forward we hope to have even more people experience the use of space through this project, and contribute to new business development and existing business growth.
