ISRO’s Aditya-L1 to Reach Its Destined Solar Orbit Today

New Delhi: India’s first space-based solar observatory, the Aditya-L1 satellite will reach its scheduled orbit on Saturday, where it will be active for the next five years.

According to ISRO Aditya-L1 will reach its destination orbit on January 6 at 4 pm after its 126-day journey that began on September 2, 2023. It has travelled around 3.7 million kilometres to reach its destination, the Lagrangian Point-1.

The 1,475-kilogram Aditya-L1 satellite will conduct scientific experiments to better understand the star of our solar system. The major scientific objectives of Aditya-L1 mission are to:

*Study solar upper atmospheric (chromosphere and corona) dynamics

*Study chromospheric and coronal heating, the physics of the partially ionized plasma, the initiation of the coronal mass ejections, and flares

*Observe the in-situ particle and plasma environment, providing data for the study of particle dynamics from the Sun

*Study the physics of solar corona and its heating mechanism

Diagnostics of the coronal and coronal loops plasma: Temperature, velocity and density

*Development, dynamics and origin of CME (Coronal Mass Ejections)

*Identify the sequence of processes that occur at multiple layers (chromosphere, base and extended corona) which eventually leads to solar eruptive events

*Magnetic field topology and magnetic field measurements in the solar corona

*The origin, composition and dynamics of solar wind, the drivers for space weather
