The Canadian Space Agency has launched a brand new satellite to help scientists study ozone depletion in the atmosphere, marking the first launch of a small Canadian-built satellite in three decades, officials said. During its mission, the C$60 million ($43 million) satellite will gather data to evaluate the impact of climate changes and of chlorofluorocarbons (CFCs) on the ozone layer, which protects the Earth from the Sun's ultraviolet rays. Magellan Aerospace Corp., the prime contractor for the mission, said the small SCISAT satellite was successfully launched into orbit by NASA
