Aditya-L1, India’s first space-based observatory to study the Sun, aims to study the Sun’s upper atmospheric dynamics, coronal heating, and more.
Aditya-L1, the first space-based Indian observatory to study the Sun, is scheduled to launch on September 2, 2023, at 11:50 Hrs. IST from Sriharikota.
Citizens are invited to witness the launch from the Launch View Gallery at Satish Dhawan Space Centre, Sriharikota.
The preparations for the launch are progressing and the Launch Rehearsal - Vehicle Internal Checks are completed.
Aditya L1 shall be the first space-based Indian mission to study the Sun and will be placed in a halo orbit around the Lagrange point 1 (L1) of the Sun-Earth system.
A satellite placed in the halo orbit around the L1 point has the major advantage of continuously viewing the Sun without any occultation/eclipses.
The spacecraft carries 7 payloads to observe the photosphere, chromosphere and the outermost layers of the Sun using electromagnetic and particle and magnetic field detectors.
The major objectives of this mission include studying Solar upper atmospheric dynamics, chromospheric and coronal heating, initiation of coronal mass ejections, and flares.
4 payloads directly view the Sun and three payloads carry out in-situ studies of particles and fields at the Lagrange point L1.
The suits of Aditya L1 payloads are expected to provide crucial information to understand coronal heating, coronal mass ejection, pre-flare and flare activities.
