Introduction

 Space systems such as satellites, interplanetary probes or space stations, must endure the extremely harsh space environment made of space plasma, hyper-velocity particles, radiation, ultraviolet rays, atomic oxygen, vacuum, thermal cycles and so on.
 When a component breaks down, it is usually impossible to repair. Therefore, we are often required to test spacecraft thoroughly. Making a equipment that works in the harsh space environment is an essential technology needed to explore the last frontier, space.

 In December 2004, Kyushu Institute of Technology established La SEINE (Laboratory of Spacecraft Environment Interaction Engineering).
 At the center, we carry out research and development of space environment technology that is necessary to achieve next-generation space utilization such as small satellites, high-speed broadband communication, high-precision positioning, remote sensing, material creation, sight-seeing, exploration, and energy generation.
 LaSEINE's mission is to serve humanity by contributing to development of space activity.



 Brief overview of the center
   La SEINE focuses on the following six main research area at present.
  1. Charging and arcing experiments
  2. Development of numerical analysis software on the charging phenomena (MUSCAT, MUltility Spacecraft Charging Analysis Tool)
  3. Hypervelocity impact experiments
  4. Surface degradation experiment of spacecraft materials
  5. Basic study on surface charging, arcing, hypervelocity impact and explosion, and research and development to fundamentally understand and mitigate each respective effect
  6. Nanosatellite testing
 Members of LaSEINE are as follows.

In addition to the five areas of A~E mentioned above, we carry out student education through the following basic research and promote joint research with domestic as well as foreign research institutions. The final goal is to provide excellent talents to the area of spacecraft environment interaction engineering by becoming a global Center of Excellence in the field,
  1. Development of mission instruments for small satellites for on-orbit demonstration of new space technology
  2. Basic research on Space Solar Power System
  3. Development of 400V photovoltaic power generation in space
  4. Analysis of on-orbit measurement data of space plasma environment
  5. Development of an orbital debris removal method
  6. Development of space environment test systems optimized for small satellites
  7. Basic research on fragments generated by hyper-velocity impact
  8. Measurement and basic research of phase shift induced by hyper-velocity impact
