SOLAR-B is the third-generation solar physics satellite of JAXA a successor to the greatly successful SOLAR-A. The satellite was launched in 2006 on a mission of elucidating the wonders and mechanism of solar activities in the corona zone by means of a high-powered reflecting telescope of 50cm diameter.
The mission of SOLAR-B is the elucidation of such issues as: the composition of the outer surface of the sun (corona and chromosphere); the magnetic microstructure of the surface of the sun's photosphere, and dynamics and coupling with the sun's corona; and elementary processes of magnetic reconnection. In order to accomplish this mission, SOLAR-B is a solar-orbit observation platform consisting of three observation systems: a visible light/magnetic field telescope, an X-ray telescope, and an extreme ultra violet (EUV) spectrum imaging system. The satellite is equipped for high-resolution, comprehensive observation of magnetism, temperature, and plasma flow in the range of the 6,000 oC surface of the photosphere, to the several tens of thousands of degrees of the corona.
