Johns Hopkins Uni puts up a big STEREO

STEREO is a pair of sun-watching satellites, which will do serious exploration of CMEs (Coronal Mass Ejections) which cause the majority of magnetic field disturbances bouncing from Earth, and also most space “weather”.

It’s good to see some basic, relatively-close-to-home space research being done, especially of our explosive inner neighbour. I’m guessing that if Earth sees problems from space, old Sol is going to be heavily involved — so the more we know about it, the better we’ll be able to react (if at all) if/when it happens.
