Space weather has become very important since we were more<br /><br />
dependent on the artificial satellites. <br /><br />
Plasma, which is filled in the outer space of Earth, determines the space weather.<br /><br />
In this talk, I will present how plasma reacts with the magnetic field of the Earth<br /><br />
and what impact plasma causes to the satellites and how it is important to<br /><br />
study the space weather for the development of the space.<br /><br />
