Aditya-L1 Solar Mission:
The Indian Space Research Organisation (ISRO) will launch the Aditya-L1 solar mission on September 2, 2023.
- The spacecraft will be launched from the Sriharikota spaceport on the PSLV rocket.
- Aditya-L1 aims to study the Sun from a halo orbit around the Lagrangian point 1 (L1) of the Sun-Earth systems, about 5 million km away from Earth.
- Mission Objective is to study the Sun, its upper atmospheric dynamics (chromosphere and corona), and understand the physics of the solar corona and its heating mechanism for the five-year time period.
- Launch Vehicle : Polar Satellite Launch Vehicle (PSLV)
- Purpose of Studying the Sun To gain a deeper understanding of the Sun’s radiation, heat, flow of particles, and magnetic fields; provide clues about the high temperature of the solar corona; understand space weather dynamics; and offer early warnings for solar events.
- Importance of L1 Point provides an unobstructed view of the Sun, even during phenomena like an eclipse; allows payloads to directly observe the Sun; makes the mission fuel-efficient.
- Benefits of Studying the Sun from Space Provides more detailed information due to the absence of Earth’s atmosphere; helps understand solar phenomena; enables monitoring of solar events and their potential impacts on Earth.
