After the huge success of the Chandryaan-3, India’s historical mission to the moon, ISRO has announced its space mission to the Sun. On September 2 at 11:50 am the Indian Space Research Organisation (ISRO) is all set to launch its first space-based solar mission Aditya L1 from Andhra Pradesh’s Sriharikota spaceport. While speaking to the media on Friday, ISRO Chairman, S Somnath stated, “We are just getting ready for the launch. The rocket and satellite are ready, we have completed the rehearsal for the launch. Tomorrow we have to start the countdown for the launch, the day after tomorrow.”

After the statement from the ISRO chief,  ISRO tweeted specifying the mission, “The 23-hour 40-minute countdown leading to the launch at 11:50 Hrs. IST on September 2, 2023, has commended today at 12:10 Hrs.”

A satellite positioned in the halo trajectory around the L1 point has the edge of constantly viewing the Sun without any occultation/eclipses.

Major Objectives of Aditya-L1 

• The major science objectives of Aditya-L1’s mission will be 
  • The study of solar upper atmospheric (chromosphere and corona) dynamics
  • Chromospheric and coronal heating
  • Physics of the partially ionized plasma
  • Initiation of the coronal mass ejections
  • Flares
• The Mission will also observe the in-situ particle and plasma environment providing data for the study of particle dynamics from the Sun. 
• The mission will also help in understanding the physics of solar nimbus and its heating mechanism. 
• Studying the diagnostics of the coronal and coronal loops plasma: Temperature, velocity, and density. 
• Development, dynamics, and origin of CMEs. 
• Identifying the sequence of processes that occur at multiple layers (chromosphere, base, and extended corona) which eventually lead to solar eruptive events will also be a major purpose of the mission.
• Magnetic field topology and magnetic field sizes in the solar corona. Factors affecting space weather (source, components, and dynamics of solar wind).

All this will give a greater advantage in monitoring solar actions and their impact on space temperature in real-time. The suits of Aditya L1 loads are anticipated to deliver the most important information to comprehend the issue of coronal heating, coronal mass ejection, pre-flare, and flare activities and their properties, dynamics of space weather, propagation of particles and fields, etc. 

On August 23, India became the first nation to safely land a spacecraft in the moon’s south pole area. The mission is proceeding, with ISRO stating its rover had verified the presence of sulfur, iron, oxygen, and other elements on the moon.
