The first space-based Indian observatory to study the Sun, Aditya-L1, is preparing for launch in September 2023.
- The satellite was developed at the U R Rao Satellite Centre in Bengaluru.
- Aditya-L1 has arrived at Sriharikota, Andhra Pradesh, where the launch will take place.
- The spacecraft is intended to be placed in a halo orbit around the Lagrange point L1 of the Sun-Earth system, situated approximately 1.5 million kilometers away from Earth.
- The halo orbit offers the advantage of continuous observation of the Sun without being obstructed by eclipses.
- This positioning will enable enhanced monitoring of solar activities and their impact on space weather in real-time.
- The satellite will carry seven payloads designed to observe the Sun’s photosphere, chromosphere, and outermost corona layers.
- The observation will be conducted using electromagnetic and particle field detectors.
- Four of the payloads will have direct views of the Sun, while the remaining three will conduct in-situ studies of particles and fields in the surrounding area.
- These studies will provide valuable scientific insights into the propagatory effects of solar dynamics in the interplanetary medium.
