Are our artificial satellites vulnerable to solar winds?

If you think of the sun as a giant globule of boiling water, the solar wind is like the wisps of steam that float away from the surface. The sun isn't made of water but is instead a sea of atoms so hot that the electrons on the outside and the protons and neutrons at the nuclei are separated from each other. read more

Normal solar winds do not make much problems.But when Sun have powerful, activities like coronal mass ejection huge amount of high energy particles go out in all directions.If earth is in its path, they will create problems for satellites and communication equipment.High magnetic field, high induced voltage all are problems.Some time satellites switch of all communications during such storms from Sun.. read more

First, the atmospheric drag effect is substantial for low earth orbit satellites, but the moon is about 1000 times further than LEO, and the relative effect of atmospheric drag is less for larger objects, so for the moon this is completely negligible. Similarly, solar wind affects large objects less than small ones. read more

The important thing is that artificial satellites have a function that often requires the satellite to be in a specific orbit. Keeping it in that orbit requires correction. Many artificial satellites, once they fail, run out of fuel, or are no longer useful, have the stationkeeping stopped. read more
