KENNEDY SPACE CENTER, FLA. - At Vandenberg Air Force Base, Calif., the Pegasus launch vehicle is moved into its hangar. The Pegasus will carry the SciSat-1 spacecraft in a 400-mile-high polar orbit to investigate processes that control the distribution of ozone in the upper atmosphere. The scientific mission of SciSat-1 is to measure and understand the chemical processes that control the distribution of ozone in the Earth’s atmosphere, particularly at high altitudes. The data from the satellite will provide Canadian and international scientists with improved measurements relating to global ozone processes and help policymakers assess existing environmental policy and develop protective measures for improving the health of our atmosphere, preventing further ozone depletion. The mission is designed to last two years.
