Experiment/Payload Overview

Brief Summary

Space Environment Data Acquisition Equipment - Attached Payload (SEDA-AP) will measure the space environment (neutrons, plasma, heavy ions, high-energy light particles, atomic oxygen, and cosmic dust) in ISS orbit and environmental effects on materials and electronic devices to investigate the interaction with and from the space environment at the Japanese Experimental Module-Exposed Facility (JEM-EF). At the same time, it is also expected to conduct on-orbit verification of APBUS (Attached Payload BUS) technology, which furnishes necessary functions when mounted on the JEM EF.

    Previous ISS Missions

    The first flight demonstration of a part of neutron monitor was carried out on board STS-89 in 1998, and next, re-flight was done as a part of the HRF(Human Research Facility ) project on board ISS in March, 2001 and the measurement continues by November 2001 .

    Experiment/Payload Description

    Research Summary

    • SEDA-AP will measure space environment data at the Exposed Facility of Japanese Experimental Module ?Kibo? on the International Space Station (ISS).


    • SEDA-AP is composed of common bus equipments that supports launch, RMS handling, power/communication interface with JEM-EF, an extendible mast that extends the neutron monitor sensor into space (1m), and equipments that measure space environment data.


    • SEDA-AP has seven measurement units as follows,(1) Neutron Monitor (NM),(2) Heavy Ion Telescope (HIT),(3) Plasma Monitor (PLAM),(4) Standard Dose Monitor (SDOM),(5) Atomic Oxygen monitor (AOM),(6) Electronic Device Evaluation Equipment (EDEE),(7) Micro-Particles Capture (MPAC) and Space Environment Exposure Device (SEED).
