NASA spacecraft Juno (see www.jpl.nova.gov/news July 12th ... is being assembled in Denver - and a unique protective shield is being added around its electronics. The magnetic field of Jupiter, and an intense barrage of cosmic radiation, is extremely powerful, and this is thought to have something to do with its faster speed of rotation. The field is shaped like a huge American doughnut surrounding the equatorial zone and as it is planned that Juno will orbit Jupiter for 15 months minimum a titanium box to protect its electronic brain is necessary - in effect, a brain box. In addition, as the radiation belt around the equator is what is thought to be the big problem NASA plans for Juno to orbit over the Poles (which should be interesting). See also www.asa.gov/juno
