    Experiment Description

    Research Overview

    • Japan Aerospace Exploration Agency Education Payload Observation 4 (JAXA EPO 4) includes artistic experiments and cultural activities. JAXA implements these activities to enlighten the general public about microgravity utilization and human space flight. JAXA understands that International Space Station (ISS), Japanese Experiment Module (JEM), Kibo, is useful for scientists and engineers as well as writers, poets, teachers, artists, etc.

    • The JAXA EPO 4 demonstrations are downlinked, edited, and used to support cultural resources for the general public.


    The objective of Japan Aerospace Exploration Agency Education Payload Observation 4 (JAXA EPO 4) investigation uses materials in the microgravity environment of the ISS/JEM to create multimedia products and artistic works that inspire the general public. The products will be exhibited at the museums. Each ISS Expedition involves different on-orbit activities and themes. The JAXA EPO4 activities are as follows:

    • Dewey’s Forest shows how gravity controls the laws of nature and influences our ways of thinking. The project is a catalyst to rediscover our relationship with plants on the ground and the age old history of our gardens. (Increment 19/20, 21/22)

    Space Applications

    JAXA EPO 4 introduces the next generation of explorers to the environment of space.

    Earth Applications

    Research performed in Kibo onboard the ISS will contribute to developing a global citizenry, expanding the future of mankind through space exploration.

    Operational Requirements

    JAXA EPO4 does not require power, telemetry, or specialized hardware. However, each demonstration requires a few hours from crewmembers, who will operate the video/camera equipment and perform demonstrations.

    Operational Protocols

    After setting up the activity, at least one crewmember will perform the activity while another films it. Each activity will have its own props (e.g., water, clay). The activity is then dismantled and some are returned to stowage and others are discarded. After the video/imagery is returned to Earth, they will be used to create artistic products for distribution to the general public.
