MacDonald, Dettwiler and Associates Ltd. (TSX: MDA), a provider of essential information solutions, announced today that NASA has increased the value of its Canadarm (“Shuttle Remote Manipulator System”) contract with MDA by approximately $28 million (CAD). This is a general contract for work on Canadarm and each work element has to be separately authorized.

Currently the envisioned work scope, which represents nearly half the contract increase, includes a third inspection boom for vital on-orbit inspections on the Space Shuttle as well as on-going product improvements and operations support.

Solutions developed by MDA have supported manned spaceflight for over 25 years and are transitioning to solutions for future exploration and servicing missions, as well as applications in hostile environments here on Earth.

The Canadian Commercial Corporation (CCC) is acting as the contracting agency between MDA and NASA and has executed the contract.
