Abstract

AbstractThe Space Environment Data Acquisition equipment (SEDA), which was mounted on the Exposed Facility (EF) of the Japanese Experiment Module (JEM, also known as “Kibo”) on the International Space Station (ISS), was developed to measure the space environment along the orbit of the ISS. This payload module, called the SEDA‐Attached Payload (AP), began to measure the space environment in August 2009. This paper reports the mission objectives, instrumentation, and current status of the SEDA‐AP. © 2012 Wiley Periodicals, Inc.

Summary

INTRODUCTION

To support future space activities, it is very important to acquire space environmental data related to the space radiation degradation of space parts and materials and spacecraft anomalies. On several satellites of the Japan Aerospace Exploration Agency (JAXA) put into obit after the Engineering Test Satellite-V (ETS-V), Technical Data Acquisition Equipment (TEDA) and Space Environment Data Acquisition Equipment (SED) have been installed to obtain the space environment data These data have been used to develop various kinds of space environment models for satellite design, to investigate space radiation degradation of space parts and materials, and to examine satellite anomalies caused by the space environment. The Space Data Acquisition Equipment is attached to the Exposed Facility of the Japanese Experimental Module (JEM-EF) on the International Space Station (ISS). This is called the SEDA-AP because it is expected to conduct in-orbit verification of APBUS (Attached Payload Bus) technology, which furnishes necessary functions when mounted on the KIBO exposed facility.
