MDA to provide critical component for the Japanese Experimental Module on the International Space Station

Richmond, BC - MacDonald, Dettwiler and Associates Ltd. ("MDA" or the "Company") (TSX: MDA), a global communications and information company, today announced that it has signed a contract with the Japan Aerospace Exploration Agency (JAXA). MDA will provide additional grapple fixtures, which provide a critical interface between the JEM Robotic Manipulator System (JEMRMS) and mission support equipment of the Japanese Experiment Module (JEM). JEM is a human-rated space facility designed and developed for conducting scientific research activities on the International Space Station (ISS), and uses the JEMRMS to support its experiments and maintenance tasks.

The grapple fixtures are specially adapted to work with the JEMRMS and some of the payloads it handles, both mechanically and electrically. With Japan’s commitment to extend its participation in the ISS program until 2024, these new grapple fixtures will support further JEM operations such as JAXA’s innovative Small Satellite Orbital Deployer for launching cubesats from the ISS.
