ADITYA-L1

INDIAN SOLAR MISSION

                       To study the Sun from a substantial distance of 1.5 million km, Aditya-L1 is the first space based observatory class Indian solar mission. Aditya-L1 is a coronagraphy spacecraft to study the solar atmosphere.

 

                        The principal scientist of the Aditya-L1 mission is Dr.Sankarasubramanian K. It is developed by the Indian Space Research Organisation(ISRO) and other Indian research institutes to study of the Sun. It weighs 1,472 kg. The cost of Aditya-L1 is 386 crore.

The science objectives of Aditya-L1:

• Study of Solar upper atmospheric (chromosphere & corona) dynamics.
• Providing data for the study of particle dynamics from the Sun, observing the in-situ particle & plasma environment.
• Physics of solar corona & its heating mechanism.
• Magnetic field & magnetic field topology measurements in the solar corona.
• Diagnostics of the coronal & coronal loops plasma: Temperature, velocity & density.
• Study of chromospheric & coronal heating, physics of the partially ionized plasma, initiation of the coronal mass ejections & flares.
• Development, dynamics & origin of CMEs.
