Zusammenfassung:	A deployable mast structure 100 comprising a body 101 configured to adopt a tubular shape when the mast structure is in a deployed configuration and a plurality of openings 102 formed in a wall of the body so as to define a plurality of integral tape-spring hinges 103 in the wall of the body. The plurality of openings being configured so as to permit the body to collapse along its longitudinal axis into a stowed configuration when the tape-spring hinges are buckled and configured to exert a force which urges the structure towards the deployed position. The structure may further comprise a plurality of reinforcing members, each configured to reinforce a section of the wall in which no tape-spring hinges are formed. Also claimed is a deployable antenna assembly, a deployable telescope assembly, a separation mechanism, a system comprising the deployable mast structure, and a method of fabricating the deployable mast structure.
