According to the website of the National Astronomical Observatory of the Chinese Academy of Sciences on September 14, recently, the 46.5nm extreme ultraviolet solar imager ( SUTRI ) carried on the Space New Technology Experiment Satellite (SATech-01) of the Chinese Academy of Sciences was successfully started up. Obtained the first dynamic imaging observations of the solar transition region (the layer between the solar chromosphere and the corona) and captured some recent activities on the sun. This is the first time that my country has carried out the detection of the solar transition zone. At present, the payload is functioning normally, and on-orbit testing and calibration are being carried out as planned.
At 12:12 on July 27, 2022, the Lijian-1 carrier rocket (ZK-1A) aboard SATech-01 successfully made its first flight at my country's Jiuquan Satellite Launch Center and was launched to near 500 kilometers sun-synchronous orbit.
According to the Science and Technology Daily, after a month of on-orbit testing, the innovative X-series launch satellite SATech-01, developed by the Institute of Microsatellite Innovation of the Chinese Academy of Sciences, is working normally, and several scientific payloads on board have been tested as planned, and the first batch of scientific results.
The Ne VII 46.5 nm line selected by SUTRI is formed in a region of about 500,000 degrees in the Sun's atmosphere (located in the high transition region), a key region connecting the lower atmosphere and the corona, and was poorly understood in the past. SUTRI is the world's first 46.5 nm solar imager based on the multi-film narrow-band filter technology. This observation is also a follow-up to the seamless spectrometer on the US Skylab (Skylab) in 1973. defects like aliasing), the first complete image of the sun was captured at 46.5nm in nearly half a century.
The National Astronomical Observatory of the Chinese Academy of Sciences stated that this successful carrying test has laid a solid foundation for the solar extreme ultraviolet spectral detection, stellar extreme ultraviolet photometry, and spectral detection that the project team is promoting, and strengthened technical reserves for China's future deep space solar exploration. It also provides important support for the construction of the Key Laboratory of Solar Activity and Space Weather in terms of space weather source monitoring and space weather forecasting based on autonomous data.
