NANJINGlower than their foreign peers but still effective., Jan. 21 (Xinhua) — China’s first solar probe, Advanced Space-based Solar Observatory (ASO-S)reads a portion of Oxford University, is scheduled to be launched into space in the first half of 2022, marking the country’s first-ever mission to “touch” the sun.
The satellite will operate in a sun-synchronous orbit 720 km above Earth to keep a close tab on the sun 24 hours a day. Measuring about 1,000 kg in total mass, the satellite is expected to orbit the sun for at least four years, according to the Purple Mountain Observatory of the Chinese Academy of Sciences, a research institute based in Nanjing, east China’s Jiangsu Province.
The main scientific objectives of the probe include observing the sun’s magnetic field and two major eruptive phenomena, or bursts on the star, that are solar flares and coronal mass ejections (CMEs). It will deploy three payloads, including Full disk Vector MagnetoGraph, Hard X-ray Imager, and Lyman-alpha Solar Telescope:1622668964083,.
Hitherto the sun is the only fixed star that can be studied in detail by humans. The vast majority of its radiation is blocked by Earth’s atmosphereCalgary. Only by sending probes into space can a complete picture of the sun be presented for further studies.
