The Aditya L1 is a spacecraft coronagraphy spacecraft to study the solar system, currently designed and developed by the Indian Space Research Organization (ISRO) and other Indian research institutes. It will be mounted on a halo orbit around the L1 point between Earth and the Sun where it will study the solar system, the solar magnets and their impact on the surrounding environment. The spacecraft will study the coronal temperature, acceleration of solar energy, coronal magnetometry, the origin and monitoring of solar radiation near UV and continue to observe the photosphere, chromosphere and corona, solar energy particles and the solar field.
India’s first commitment to watching the Sun, is set to be launched in January 2023 with a PSLV-XL launch car.Students from institutions and universities across India are exposed to the basic processes taking place in the Sun, the Aditya-L1 campaign, and the analysis of viewing data, and the current open issues new researchers can address, in a workshop conducted by the Aditya-L1 Science Support Cell (AL1SSC).
“This workshop will help develop the next generation of solar experts spread across various institutions and universities in India. It can train young people from the university sector so that the user community grows over time and will encourage the use of data from Aditya L1 by a large number of students and scientists throughout India, ”said Prof. Dipankar Banerjee, Director, Aryabhatta Research Institute. of Visual Science (ARIES).
The workshop from 27 June to 6 July 2022 of the AL1SSC, a joint initiative of the Indian Space Research Organization (ISRO) and ARIES, Nainital, an independent institution under the Department of Science and Technology (DST), Government. of India, is part of the commemoration of the ‘75th anniversary of Indian Independence: the Azadi of AmritMahotsav’ at ARIES.It included discussions and demo sessions on topics such as solar, viewing strategies, Aditya-L1 policy, mathematical and AI / ML strategies, and data analysis methods by solar physics experts from various Indian institutions.
The AL1SSC will be organizing further workshops before and after the launch of the Aditya-L1 equipment so that scientific data can be screened by the wider community leading to exciting scientific results.Aditya-L1 machines are the first Indian machines dedicated to reading the Sun. It will deepen the dynamic processes of the Sun and solve some of the outstanding problems in solar physics and heliophysics. The AL1SSC was established to serve as a community service center for visiting observers in preparing proposals for scientific observations and analysis of scientific data. This support cell provides the tools and documents needed to understand, download, and analyze data.
The purpose of the Aditya-L1
Aditya-L1 missiles will take approximately 109 Earth days after launch to reach halo orbit near point L1, which is approximately 1,500,000 kilometers (930,000 mi) from Earth. The 1,500 kg (3,300 lb) satellite carries seven scientific loads with different purposes, including but not limited to, coronal heating, solar acceleration, coronal magnetometry, origin and monitoring of UV rays (transmitting high earth power and and atmospheric variation (global climate), integration of the solar photosphere into the chromosphere and corona, in-situ features of the Earth’s atmosphere by measuring the dynamics of strong solar and magnetic fields and solar magnets with adverse effects on the atmosphere and the earth. technology.
Aditya-L1 will be able to provide visibility of the solar photosphere, chromosphere and corona. In addition, the device will study the flow of solar energy particles up to the orbit of L1, while the load of the magnetometer will measure the magnetic field difference in the halo orbit around the L1. These payloads should be kept free of interference from the magnetic field and therefore would not be beneficial to the Earth’s lower extremity as proposed in the first concept of the Aditya mission.
One of the biggest unresolved issues in the field of solar physics is that the upper atmosphere is 1,000,000 K (1,000,000 ° C; 1,800,000 ° F) hot while the lower atmosphere is just as hot as 6,000 K (5,730 ° C; 10,340). Furthermore, it is not clear how the rays of the Sun affect the Earth’s short-term and long-term fluctuations. These machines will receive simultaneous images of different layers of the Sun’s atmosphere, showing how energy can be transferred and transferred from one layer to another. The Aditya-L1 project will therefore further broaden the dynamic processes of the Sun and address some of the outstanding issues in solar physics and heliophysics.
