 Information
Announcement on a partial termination the service for the Satellite Environment Information Service (SEES) (update:09/Oct./2018)
 We would like to extend our deep appreciation for a long patronage for SEES.
 Unfortunately, we regret to inform you that we will be terminate the support service for Sky View, World Map View since last January 2019 with Oracle's Java applet support termination.
 Thank you for using it for a long time.
 With the end of the service, we apologize for your great inconvenience.

 About SEES
SEES (Space Environment & Effects System) is the database system for provide data and model concerned with space environments - High Energy Particles, Galactic Cosmic Rays, Atomic Oxygen, Plasma, magnetic field, etc - and effects from space environments - Single Event Upset, Degradation of Solar Cell, Differential potential, Total Dose, Degradation of Thermal Control Material, etc .

In designing spacecraft, we should reflect the results from many space activities. The results - not only we had but also we are going to have - are space environments data - Space Radiation, etc - and Degradation, Anomaly data of parts and materials. (Degradation, Anomaly are caused from being in space environments.) In the recognition of the importance of gathering these data, JAXA has mounted measuring instruments onboard each spacecraft since ETS-V was mounted.
