Splitting of the Sun's global oscillation frequencies by large-scale ows can be used to investigate how rotation varies with radius and latitude within the solar interior. The nearly uninterrupted observations by GONG yield oscillation power spectra with high duty cycle and signal-to-noise ratio. Frequency split-tings derived from GONG...
The POLAR Investigation of the Sun (POLARIS) mission uses a combination of a gravity assist and solar sail propulsion to place a spacecraft ina 0.48 AU circular orbit around the Sun with an inclination of 75◦ with respect to solar equator. This challenging orbit is made possible by the challenging development of solar sail propulsion. This...
