XEUS Mirror Sectors on ISS

Robotic in-orbit assembly and/or maintenance of space structures is an enabling technology for large space structures that, due to their substantial mass or dimensions, cannot be assembled on ground and hence be transported into space with conventional space vehicles The objectives of the Robotic Assembly of Large Space Structure (RALSS) ESA-Study, conducted by Alenia Spazio, as Prime Contractor, with SENER and Tecnospazio as Sub-contractors, are related to this important technology or topic development, starting with some detailed analysis of the first important example of this type of activity, that is the on-going International Space Station (ISS) in-orbit build-up or assembly.
