MDA's Robotics Play a Crucial Role in Final Hubble Servicing Mission



    BRAMPTON, ON, May 11 /CNW/ - MacDonald, Dettwiler and Associates Ltd.
(TSX: MDA), a provider of essential information solutions, announced that when
the space shuttle Atlantis lifts off from Kennedy Space Center this afternoon,
robotic technology development by MDA (TSX:MDA) will play a central role in
the safety and success of this final and historic servicing mission to the
Hubble Space Telescope.
    The mission builds on nearly three decades of MDA's orbital flight
servicing heritage in support of NASA's and the Canadian Space Agency's human
spaceflight and space exploration endeavours.
    Over the 11-day mission, MDA's robotics will be used extensively to
extend Hubble's life and scientific discoveries into the next decade and
ensure the safety of Atlantis' crew.
    With safety paramount to the success of the mission, the first task for
MDA's Canadarm and Inspection boom will be to perform a detailed inspection of
the orbiter's thermal protection system and crew cabin to ensure no damage
occurred during launch.
    Following the inspection, Atlantis will rendezvous within 35 feet of the
telescope and Canadarm will reach out, grapple telescope and berth it in the
shuttle's cargo bay.
    With the aid of Canadarm, a series of five spacewalks will be performed
to upgrade and expand the capabilities of the orbiting observatory. When the
servicing tasks are complete, Canadarm will be used to unberth the telescope
sending Hubble off to explore the universe.
    At the conclusion of the mission, a final robotic task will be conducted
to inspect the orbiters thermal protection system, including its wing leading
edge panels, nose cap and underside tiles. In the unlikely event of damage
from debris at launch or space debris that would compromise the safe return of
Atlantis and its crew, the Space Shuttle Endeavour is poised for launch with
MDA's robotic systems onboard to assist in the rescue.
    This mission underscores the continuing needs for human and robotic
collaboration for space science and exploration.
