AB: Due to the effects of solar rotation, solar observations from vantage points well out of the ecliptic plane will enable measurement of the magnetic fields and convective flows in the polar regions of the Sun that are crucial to understanding the solar magnetic dynamo. These same vantage points are also near optimal for measurement of the solar atmosphere at the poles, and allow a panoramic view of the solar corona, coronal mass ejections and the inner heliosphere. In this poster, we present results from the Vision Mission Study of a Solar Polar Imager (SPI) mission. The SPI mission uses solar sail propulsion to place a sun pointed spacecraft in a 0.5 AU circular orbit around the Sun with an inclination of 75 degrees. Details of the scientific objectives, instrument suite, observations and mission design are presented.
