Canadian Space Agency

And the countdown begins...

SCISAT-1, the first new Canadian scientific satellite since 1971, is scheduled for launch by the National Aeronautics and Space Administration (NASA) from Vandenberg Air Force Base, California in mid-year 2003.

SCISAT-1 will help a team of Canadian and international scientists improve their understanding of the depletion of the ozone layer, with a special emphasis on the changes occurring over Canada and in the Arctic.

The scientific goal of the SCISAT-1/ACE (Atmospheric Chemistry Experiment) mission is to measure and understand the chemical processes that control the distribution of ozone in the Earth's atmosphere, particularly at high latitudes. The measurements obtained will be combined with data gathered by ground-based, balloon-based and other space-based projects in order to obtain the best possible information to predict future trends relating to the ozone layer and its depletion. The data, recorded as SCISAT-1 orbits the Earth, will provide Canadian and international scientists with improved measurements relating to global ozone processes and help policy makers assess existing environmental policy and develop protective measures for improving the health of our atmosphere. The ACE mission is designed to last at least two years.

Two Lesson Plan Portfolios have been designed by the YES I Can! Science team to facilitate teaching science concepts related to this important mission.
