Effects of space weather, from ESA.


The science of space weather is concerned with understanding the causes and effects of varying conditions in mainly the Earth’s magnetosphere and atmosphere that are mostly driven by the Sun.

The solar wind is a supersonic flow of an extremely fast and tenuous plasma that is expelled by the Sun at all times, and interacts with other solar system objects such as planets, comets and asteroids. It carries a magnetic field that is shaped like a spiral due to the rotation of the Sun.

Normally, the slow solar wind, which nevertheless impacts Earth with 400 kilometres per second, flows relatively quiet around the Earth’s magnetic field. However, during time intervals of strong southward magnetic fields and higher solar wind speeds, which are caused by solar storms, also known as coronal mass ejections, and fast solar wind streams, energy is transferred into the magnetosphere and the magnetic field of the Earth is temporarily disturbed. This results in a so-called geomagnetic storm.

The prediction of the solar wind impacting the Earth's magnetic field is a major unsolved problem in space science. For example, an accurate solar wind forecast would tell us where and when the aurora lights up the sky, or whether power grids are at risks of failure, besides numerous other impacts on space and ground based technological infrastructure.


This figure shows a roundup of current solar wind and space weather spacecraft missions, as well as future concepts.
