Canadian space environment program and international living with a star

Canada has a vibrant and balanced research program in the space environment discipline. Two major thrusts are manifested in the current program direction, the integration of ground instruments for the remote-sensing of the magnetosphere-ionosphere system (geospace monitoring), and the development and flight of a small satellite for the study of particle acceleration and radio tomography in the auroral ionosphere (enhanced polar outflow probe). A general description of the mission science objectives is given. These and other potential Canadian contributions are discussed in the context of international living with a star.
