Space Weather

11 August 2018

Space weather is the term used to describe interactions of the solar wind with the Earth's magnetosphere. Nothing to do with climate. At … NASA have launched twin satellites to study the Van Allen belts – and the way the solar wind is deflected by earth's magnetosphere. Later, the programme will be expanded to cover all the effects – it is hoped. Meanwhile, the Japanese already have a satellite, launched in 2016, exploring the Van Allen belts. The satellite is equipped with multiple sensors in order to monitor what they call the Plasma Wave Experiment (peering at the electric fields and plasma waves in the inner magnetosphere). Data from the sensors has recently been published in 'Earth, Planets and Space' journal.
