ESA BR-345 Solar Orbiter: Facing the Sun

Solar Orbiter is a mission dedicated to solar and heliospheric physics. It will address big questions in Solar System science to help us understand how the Sun creates and controls the heliosphere, the giant bubble of plasma that surrounds the whole Solar System and influences Earth and the other planets within it. The spacecraft will provide close-up, high-latitude observations of the Sun to gain new information about the solar wind, the heliospheric magnetic field, solar energetic particles, transient interplanetary disturbances and the Sun's magnetic field.
