Predicting space weather and getting an accurate assessment of the impact on ground and space infrastructure and our lives

Learn more about space weather!

Space weather is a phenomenon in the space environment that fluctuates in response to solar activity. Large explosions on the surface of the sun can cause large-scale space environmental disturbances around the Earth, affecting society and life. For example, there is concern that an increase in high-energy particles, large disturbances in the ionosphere, and the generation of geomagnetically induced currents could affect air traffic control, satellites, communications, and power grids.

More accurate space weather forecasts

Research in the field of heliospheric system science (Field of solar science, solar earth and planetary system science) based on comprehensive observations of the heliosphere by the Heliospheric Science Center, including the Solar Observation Satellite 'Hinode', the Geospace Exploration Satellite ‘Arase', the Mercury Exploration Satellite 'Mio', and the High Sensitivity Solar Ultraviolet Spectroscopic Observation Satellite ‘SOLAR-C', which will be responsible for heliospheric system science in the 2020s, and disclosure of higher-order data processes and data will contribute to the improvement of the understanding of space weather phenomena, the elucidation of the fluctuation mechanism of the space environment, and the improvement of the accuracy of space weather forecasts. Improving space weather forecasts is necessary to reduce the impact on ground and space infrastructure, and it will lead to a sustainable society by realizing stable use of space.

• 
  By improving the understanding of space weather phenomena through observations by satellites and probes related to space weather, ground observations, numerical simulations, etc., we will contribute to the construction of resilient infrastructure through the improvement of accuracy of space weather forecasts.
• 
  By providing basic information on space weather phenomena through comprehensive observations and numerical simulations of the heliosphere, we will contribute to the realization of inclusive, safe, resilient and sustainable urban and human settlements.
• 
  By deepening our understanding of the global environmental impact of space environmental change, we will contribute to the prompt understanding of climate change that affects the entire planet and the formulation of measures to mitigate its impact.
