Indian Space Research Organisation’s (ISRO) Chief S Somanath announced that Aditya-L1 mission, the first space-based Indian observatory to study the Sun will be likely launched by the first week of September. This announcement comes hours after ISRO’s third lunar mission Chandrayaan-3 made a successful landing on the lunar surface.
ISRO will launch the PSLV-C57 for the Aditya L1 mission on September 2. This is the first space-based Indian observatory to study the Sun from ISRO, which will be scheduled for launch on September 2, 2023, at 11:50 IST from Satish Dhawan Space Center in Sriharikota.
Aditya L1 will be ISRO’s 2 space-based astronomy mission after AstroSat, which was launched in 2015. Aditya 1 was renamed as Aditya-L1. The Aditya 1 was meant to observe only the solar corona.
AstroSat, was launched in September, 2015, by PSLV-C30 from Sriharikota (Andhra Pradesh). It is the first dedicated Indian astronomy mission aimed at studying celestial sources in X-ray, optical and UV spectral bands simultaneously.
Aditya L1 would be the first space-based Indian mission to study the Sun. The spacecraft shall be placed in a halo orbit around the Lagrange point 1 (L1) of the Sun-Earth system, which is about 1.5 million km from the Earth. A satellite placed in the halo orbit around the L1 point has the major advantage of continuously viewing the Sun without any occultation/eclipses. This will provide a greater advantage of observing the solar activities and its effect on space weather in real time. Earlier, on July 14, ISRO, taking to Twitter informed that Aditya-L1, the first space-based Indian observatory to study the Sun was getting ready for the launch.
