India’s first Solar research mission will be launched by ISRO in 2023 and it is dubbed Aditya-L1.
After several years of development, the Indian Space Research Organization (ISRO) is expected to launch Aditya-L1 this year. This will be India’s first space mission to study the Sun. The rocket will be carried by the Polar Satellite Launch Vehicle (PSLV). The Aditya-L1 instruments are programmed to observe the solar atmosphere, especially the chromosphere and corona. The Aditya L1 payload is expected to provide important information for understanding issues such as coronal heating, coronal mass ejection (CME), solar pre-flash, and flare activities. generate solar energy. The Aditya-L1 mission will also help reveal the dynamics of space weather, the propagation of solar particles, etc.
ISRO confirmed that “the spacecraft will be placed in a halo orbit around the Lagrange point 1 (L1) of the Solar-Earth system, approximately 1.5 million km from Earth. The earth. “Putting a satellite in a halo orbit around L1 will be a great advantage for scientists to have a continuous view of the Earth. Sun without any eclipse. This will allow real-time observations of solar activities and their effects on solar energy spatial weather. The spacecraft carries a total of seven payloads to observe solar activity.
Load of Aditya-L1
- VELC (visible emission line)
- SUIT (solar ultraviolet imaging telescope)
- SoLEXS (solar low-energy X-ray spectrometer)
- HEL1OS (high-energy L1 orbital X-ray spectrometer)
- ASPEX (Aditya Solar Wind Particle Experiment)
- PAPA (Plasma analysis package for Aditya)
- Advanced high resolution three-axis digital magnetometer.
Launching Aditya-L1
The Aditya-L1 mission will be launched in June or July of this year, ISRO president S. Somanath said during the handover ceremony of the Visible Line Emission Coronagraph (VELC) payload on January 26. VELC is the payload. The largest is carried on the Aditya -L1. However, ISRO has yet to announce the final date of the Aditya-L1 launch.
Objective of the quest Aditya-L1
Its main objectives are to study the upper atmosphere of the Sun, which is the chromosphere and corona, as well as its heating, the physics of partially ionized plasma, the initiation of of coronal mass eruption, coronal flare physics and its heating mechanism. In addition, it will help examine the development, dynamics and origins of CME and other factors for space weather.
