Dosimetry measurement of heavy particle beam in a space shuttle and investigation of its effect on living organisms (Radiation): What is the space weather forecast?
In the 21st century, it is expected that manned space activity and space utilization will make further progress. However, space is a harsh environment: almost a vacuum bathed with radiation and penetrated by streams of energetic particles. These particles and interplanetary disturbances are hazardous to space equipment, astronauts, etc. This is why the Communications Research Laboratory decided to start the Space Weather Forecast Program of Japan. This program is realized by the accumulation of knowledge on basic physical processes governing the space environment, and is expected to play a significant role in the protection of human health in space and reliable operation of space equipment. In this investigation, the space weather information/warning system was tentatively operated, and the space environment (solar and geomagnetic activities) during the shuttle flight has been being analyzed. The exchange of RRMD (Real time Radiation Monitoring Device) data and the space weather information were performed by the computer network and the facsimile every few days, and was useful for the ground operation of the radiation observation. The radiation data is now being analyzed and tentative results show stationary particle penetration around the South Atlantic Anomaly.
