Launching of ISRO's Aditya L1 today at 11:50 AM: will go to the Lagrange point, 1.5 million km from Earth, from there will study the Sun
After the successful landing of Chandrayaan-3, the Indian Space Research Organization (ISRO) is preparing to study the Sun. For this, Aditya L1 spacecraft will be launched from Satish Dhawan Space Center in Sriharikota through PSLV-C57 rocket today at 11.50 am.
Aditya L1 will be the first Indian mission to study the Sun. This spacecraft will reach Lagrange Point-1 (L1) 4 months after launch. There is no effect of eclipse on this point, due to which the Sun can be easily studied from here. The estimated cost of this mission is Rs 378 crore.
What is Lagrange Point-1 (L1)?
Lagrange points are named after Italian-French mathematician Joseph-Louis Lagrange. It is colloquially known as L1. There are five such points between the Earth and the Sun, where the gravitational force of the Sun and the Earth balances out and becomes a centrifugal force.
In such a situation, if any object is kept at this place then it easily remains stable between the two and less energy is also required. The first Lagrange point is at a distance of 1.5 million kilometers between the Earth and the Sun.
Eclipse neutralized at L1 point, hence sending here
Aditya spacecraft will be placed in a halo orbit between the Sun and the Earth. ISRO says that a satellite placed in a halo orbit around the L1 point can see the Sun continuously without any eclipse. With this, real-time solar activities and space weather can also be monitored.
Aditya L1's 7 payloads will understand the Sun
Aditya spacecraft will understand the storms arising on the Sun by staying at L1 i.e. Lagrangian point of Sun-Earth. It will test the orbit around the Lagrangian point, photosphere, chromosphere and the outermost layer of the corona through 7 payloads from different web bands.
Aditya L1's seven payloads will provide information to understand coronal heating, coronal mass ejection, characteristics of pre-flare and flare activities, movement of particles and space weather. Aditya L-1 will study the solar corona and its heating mechanism.

7 payloads will go with Aditya L1
The seven payloads that will be sent with the Aditya L1 mission are Visible Emission Line Coronagraph (VELC), Solar Ultra-Violet Imaging Telescope (SUIT), Aditya Solar Wind Particle Experiment (ASPEX), Plasma Analyzer Package for Aditya (PAPA). , Solar Low Energy X-ray Spectrometer (SoLEXS), High Energy L1 Orbiting X-ray Spectrometer (HEL1OS) and Magnetometer payload.
The Visible Emission Line Coronagraph (VELC) payload will study the dynamics of the solar corona and coronal mass ejections.
The Solar Ultra-Violet Imaging Telescope (SUIT) payload will image the solar photosphere and chromosphere at near ultraviolet wavelengths and study changes in solar irradiance (light energy coming from the Sun to Earth).
The Aditya Solar Wind Particle Experiment (ASPEX) and Plasma Analyst Package for Aditya (PAPA) payloads will study the solar wind (solar storm that arises around the Sun) and energetic particles. This payload will also study the energy distribution of these particles.
The Solar Low Energy X-ray Spectrometer (SoLEXS) and the High Energy L1 Orbiting
The magnetometer payload will study the interplanetary magnetic field at the L1 point.
Aditya L1 made in India only
According to an ISRO official, Aditya L1 is a completely indigenous effort to be made with the participation of the country's institutions. The Indian Institute of Astrophysics (IIA) Visible Emission Line Coronagraph in Bangalore created its payloads. While the Inter-University Center for Astronomy and Astrophysics Pune has developed the Solar Ultraviolet Imager payload for the mission.
Why is the study of the Sun necessary?
The Sun is the center of the solar system in which our Earth exists. All the eight planets revolve around the Sun. There is life on earth because of the Sun. Energy flows continuously from the Sun. We call them charged particles. By studying the Sun, it can be understood how changes in the Sun can affect space and life on Earth.
