  5. Demeter debuts science mission

    Publishing date:

    September 24, 2004

    Launched on 29 June, the Demeter microsatellite (Detection of Electro Magnetic Emissions Transmitted from Earthquake Regions) is now on orbit and operational. But before embarking on its mission to study electromagnetic disturbances in the ionosphere associated with earthquakes and tremors, the satellite first had to undergo in-orbit checkout. Throughout the summer, the project team and scientists minded the first newborn in the Myriade series to monitor its flight performance.
