MARSIS main antenna during Mars Express payload tests. One of the two main radar booms is shown here, a 20-metre long hollow cylinder, of 2.5 centimetres diameter, folded up in a box like a concertina (accordion). When the box is opened, the elastic energy of the compressed glass-fibre booms will let them unfold like a jack-in-the-box.
