The Indian Space Research Organization (ISRO) is targeting several space missions this year. First, we will soon experience the historic Mission Chandrayaan-3 landed on August 23, 2023, ISRO is also planning to launch a spacecraft that will study the Sun, its environment, solar flares, and solar storms. Will study Coronal Mass Ejection, and many more. With a big plan ahead this year, we’re excited to see what new studies and discoveries will reveal about our Sun and Moon. Know in detail about the Surya Mission.
About Aditya L1 mission
Aditya L1 mission will be India’s first solar mission that will study the Sun for nearly 5 years. The ISRO PSLV rocket spacecraft is set to take flight from Sathish Dhawan Space Centre SHAR (SDSC SHAR), Sriharikota on 2 September 2023.
According to an ISRO report, the spacecraft will have seven scientific payloads to study the sun from different angles. The spacecraft will be placed in low Earth orbit (LEO) in the Lagrange point L1 of the Earth-Sun system. The position is perfect for scientists to study the Sun without any blockage from the region.
The mission will get insight into the Sun’s photosphere, chromosphere, and the outermost layer. Throughout the mission, it aims to study the solar atmosphere, solar wind, coronal heating, coronal mass ejections (CMEs), solar flares, and more.
