Cluster spacecraft detects elusive space wind
The European Geosciences Union said:
“After long scrutiny of the data, there it was, a slow but steady wind, releasing about 1 kg of plasma every second into the outer magnetosphere: this corresponds to almost 90 tonnes every day. It was definitely one of the nicest surprises I’ve ever had!” said Dandouras of the Research Institute in Astrophysics and Planetology in Toulouse, France.
The plasmasphere is a region filled with charged particles that takes up the inner part of the Earth’s magnetosphere, which is dominated by the planet’s magnetic field.
