    NASA's Magnetospheric Multiscale Mission was launched on Mar 13. The mission consists of four identical spacecraft, each with a mass of 1000 kg plus 400 kg of propellant. The spacecraft will fly in a tetrahedral formation some tens of kilometres apart to disentangle spatial and temporal fluctuations in the magnetospheric particle and field environment. They will deploy wire booms with a span of 112 metres to measure electric fields. Additional Details: here....
