MSCI Wins Contract to Provide Reaction Wheels to NASA's LADEE Program

    MISSISSAUGA, Ontario, May 21 /CNW/ -- Microsat Systems Canada Inc.
(MSCI), formerly the Space Division of Dynacon Inc., announced today that the
company has won a contract with the NASA Ames Research Center to provide
engineering model Reaction Wheels for the Lunar Atmosphere and Dust
Environment Explorer (LADEE) mission.

    The main objective of NASA's Lunar Atmosphere and Dust Environment
Explorer (LADEE) mission will be to orbit the Moon and characterize the
atmosphere and lunar dust environment.

    LADEE implements an early priority of the National Research Council's
report, The Scientific Context for the Exploration of the Moon (NRC, 2007),
namely to "determine the global density, composition, and time variability of
the fragile lunar atmosphere before it is perturbed by further human

    LADEE will have a mass about 130 kg and will be launched together with
the JPL-led GRAIL mission on a Delta-II launch vehicle, scheduled for 2011.

    In addition to the scientific objectives, the mission will be testing a
new spacecraft architecture called the 'Modular Common Bus' -- which is being
developed by NASA as a flexible, low cost, rapid turnaround spacecraft for
both orbiting and landing on the Moon and other deep space targets.  It is
hoped that such a capability will enable the Agency to perform future
scientific missions at a reduced cost.

    LADEE is currently in the study phase and the MSCI Reaction Wheels will
be used in the ACDS hardware-in-the-loop simulator.  The MSCI Reaction Wheels
will function as full flight models in the simulator.

    "We are thrilled to be participating in this program," says David R.
Cooper, Chief Executive Officer, MSCI, "and look forward to continuing our
relationship with NASA which started 7 years ago with the ChipSat program."
