Christened "Maxwell', after James Clerk Maxwell (1831-1879) who unified the physical laws of electricity and magnetism with equations known as 'Maxwell's Equations'. the new EMC chamber that has recently come on stream at ESTEC is the perfect facility for testing the electrical and magnetic characteristics of Europe's largest and most advanced spacecraft payloads. The chamber's spacious internal dimensions of 14.5 metres x 10.7 metres x 11 metres mean that it can handle the largest satellites compatible with Arione-5 single-passenger launches.
