The hottest grassland sky eye in China will intera
2022-10-13- Detail
"With the launch of the 'Parker' Solar Probe in the United States, the 'heavenly eye' of the Chinese grassland began to pay close attention to the probe and will interact with the scientific research of solar observation." Yan Yihua, chairman of the sun and heliosphere branch of the International Astronomical Union and director of the Key Laboratory of solar activity of the Chinese Academy of Sciences, said
at 15:31 Beijing time on August 12, a heavy carrier rocket carrying the "Parker" solar probe was launched from the United States. According to reports, the American "Parker" solar probe will fly around the sun in an elliptical orbit and gradually approach the sun through seven gravitational orbit changes near Venus. Its minimum perihelion is about 6.1 million kilometers away from the surface of the sun, much closer than the distance between mercury and the sun
the planned mission period of the "Parker" solar probe is 7 years. During this period, as the new equipment is put into use, the ming'antu radio spectrum heliograph, the "eye of heaven" in China's grassland, will become more powerful and become a special solar radio spectrum imaging device with the strongest observation ability on earth, which means that the two can carry out more scientific research interaction of solar observation
it is learned that in the future, with the completion of infrastructure construction projects for major national scientific and technological foundations, such as the compact deformation and anti slip characteristics better than EVA foam board mingantumi wave ten meter wave radio heliograph and interplanetary scintillation telescope, which are limited by the flow of oil sources, the radio observation range of China's Grassland "heavenly eye" will be expanded from 700000 kilometers to 7million kilometers from the sun's surface, and the observation range of "Parker" solar detector will overlap
Yan Yihua said that one of the scientific tasks of the "Parker" solar probe is to study how the solar wind accelerates to leave the corona and enter space. The interplanetary scintillation telescope to be built in China is used to detect the three-dimensional space structure of the interplanetary solar wind, and after its completion, it will become a special telescope for interplanetary scintillation with the highest sensitivity and the best performance in the world"no matter from the observation range, cm, or from the specific scientific tasks, the 'heavenly eye' of the Chinese grassland will form a scientific research interaction with the 'Parker' solar detector. The observation data of both sides can be analyzed at the same time, verified in both directions, and complemented each other. Continue to strengthen research and development," said Yan Yihua
