Key Points

The Indian Space Research Organisation (ISRO) on Saturday successfully performed the final manoeuvre to inject Aditya-L1 spacecraft -- the first space-based Indian observatory to study the Sun -- into its final destination orbit, nearly 1.5 million kilometres from the Earth...

Under the visionary leadership of PM @narendramodi,yet another success story scripted by Team #ISRO. #AdityaL1 reaches its final orbit to discover the mysteries of Sun-Earth connection," said Jitendra Singh, MoS Science and Technology...

"Using the special vantage point L1, four payloads directly view the Sun and the remaining three payloads carry out in-situ studies of particles and fields at the Lagrange point L1, thus providing important scientific studies of the propagatory effect of solar dynamics in the interplanetary medium," according to the space agency...

The suits of Aditya L1 payloads are expected to provide the "most crucial information" to understand the problem of coronal heating, coronal mass ejection, pre-flare and flare activities and their characteristics, dynamics of space weather, and propagation of particles and fields, officials said...

Study of the Solar upper atmospheric (chromosphere and corona) dynamics.Study of chromospheric and coronal heating, physics of the partially ionized plasma, 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.Physics of the solar corona and its heating mechanism.Diagnostics of the coronal and coronal loops plasma: Temperature, velocity and density.Development, dynamics and origin of coronal mass ejections (CMEs).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.Drivers for space weather (origin, composition and dynamics of solar wind)..
