& ldquo; Xihe & rdquo; successful launch: the Chinese satellite to detect the sun in the sky

     At 18:51 on October 14, China in the Taiyuan Satellite Launch Center using the Long March II D carrier rocket, successfully launched the first solar detection science and technology test satellite & ldquo; Xixihe & rdquo;. The star will realize the international first solar H & alpha; band spectral imaging space exploration, fill the gaps of high quality observation data in the solar eruption source area, improve China's research capacity in the field of solar physics, China's space science exploration and the development of satellite technology is of great significance.

     This is of great significance to China's satellite business: First, the realization of China's solar exploration zero breakthrough, marking China's formal entry into the era of & ldquo; sun & rdquo; Second, in-orbit testing of ultra-high-pointing accuracy, ultra-high stability of the new satellite platform technology, to promote China's high-precision satellite platform technology, revolutionary, leaps and bounds in development; Third, to open up the country's solar exploration of international cooperation and exchange of new situations Thirdly, it is to open up a new situation of international cooperation and exchange in China's solar exploration, which will significantly improve China's international status in the field of solar physics research; fourthly, it is to stimulate the enthusiasm of exploring space science and cultivate innovative high-end talents.

 “Xixihe” satellite in orbit during operation, will observe the solar flare and coronal mass ejection of the photosphere and chromosphere performance, explore the source region of the solar eruption of the dynamic properties and trigger mechanism, while detecting the formation of the solar dark bar and evolution process of the chromosphere performance, revealing its intrinsic connection with the solar eruption, but also to obtain the full-sun surface H & alpha; band Doppler velocity distribution, research Solar lower atmosphere dynamics process, to solve the & ldquo; solar eruption from the inside and the surface of the whole process of energy transfer physical model & rdquo; and other scientific issues to provide important support.

     China's first solar exploration science and technology test satellite named & ldquo; Hsihe & rdquo;. Xixi and for the Chinese ancient myth of the goddess of the sun and the development of the goddess of the calendar, and the image of the mother of the sun for people to recognize. Zhao Jian said, the name takes the meaning of & ldquo; follow xi and harness the celestial horse, the ambition of the stars in the sky & rdquo;, symbolizing the origin and expansion of China's exploration of the sun.
