Today, R&D continues in many missions on various concepts for deployable structures in space. One unique concept was tested on the SFU. It is a coil-extension mast that uses no hinges to support scientific instruments and/or deployable structures such as the flexible 2-dimensional deployable structure solar array (2-D array). The highly rigid, jointed mast used in the 2-D array was modified for HALCA’s deployable antennas. Research is also carried out on smart and adaptive structures and inflatable structures for future space systems, thus creating many pioneer structures.
