Will work from Earth orbit, as opposed to the Sun-grazing paths of US and EU solar probes

The 888kg satellite is equipped with a Full-disk MagnetoGraph , Lyman-alpha Solar Telescope and Hard X-ray Imager . The FMG measures the vector magnetic field, the LST measures the light near the corona emitted from the Sun's full disk in the ultraviolet and visible light wavelengths – known as the Lyman-alpha bandwidth – and the HXI detects high-energy radiation during solar flares.

Work on the $140 million mission began in 2012. China has hustled to get the observatory into position before 2025, the expected peak of activity in the current 11-year solar cycle. China's first solar observatory joins NASA's Parker Solar Probe and the European Space Agency's Solar Orbiter already in orbit.how solar switchbacks – the phenomena that cause the Sun's magnetic field to flip – are formed.the Sun. Its mission goals are to trace the flow of energy that heats the corona and accelerates solar wind, learn about magnetic fields and determine what gets energetic particles moving.

Both Parker and the ESA's effort will get a lot closer to Sol than Kuafu-1. Parker will pass within just seven million kilometers of Sol and Europe's craft will close to within 30 million klicks . It may seem a bit excessive to have to go into space to study the Sun – it is, after all, right there. You can see it with the naked eye . Studying the star from a distance – particularly from Earth – yields limited results because the atmosphere absorbs and dampens solar emissions. Getting outside the atmosphere is like taking the blinders off and seeing the Sun in a whole new light. ®
