After the successful soft landing of Chandrayaan-3, ISRO is now set to launch country’s maiden solar mission Aditya-L1. Aditya-L1 spacecraft is designed for providing remote observations of the solar corona and in situ observations of the solar wind at L1 (Sun-Earth Lagrangian point), which is about 1.5 million kilometres from the earth.
It is India’s first solar space observatory and will be launched by the PSLV-C57. It will carry seven different payloads to have a detailed study of the sun, four of which will observe the light from the sun and the other three will measure in-situ parameters of the plasma and magnetic fields.
Aditya-L1 mission launch date and time
The solar mission is scheduled for lift-off on September 2 at 11:50 am from the Sriharikota spaceport. On August 30, ISRO said that its Aditya-L1 mission, designed to study the Sun, has completed launch rehearsals and internal checks.
Where to watch ISRO’s Aditya-L1 mission LIVE
The live telecast can be watched on the Doordarshan channel or ISRO’s YouTube channel. ISRO on 1 September has also shared the link of the live telecast of the Aditya-L1 Mission. The launch of Aditya L1 is timed at 11:50 am (IST) tomorrow.
The countdown for the launch of India’s maiden solar mission, Aditya L1, has commenced, The Indian Space Research Organisation said on Friday.
The spacecraft would be launched by PSLV-C57 rocket. The Aditya-L1 mission aims at studying the Sun from an orbit around the L1. It will carry seven payloads to observe the photosphere, chromosphere and the outermost layers of the Sun, the corona, in different wavebands.
Aditya-L1 is a fully indigenous effort with the participation of national institutions. It can provide observations on the corona, and on the solar Chromosphere using the UV payload and on the flares using the X-ray payloads. The particle detectors and the magnetometer payload can provide information on charged particles and the magnetic field reaching the halo orbit around L1.
When the country’s maiden solar mission, Aditya L1 onboard the reliable PSLV lifts off from Sriharikota on Saturday for its 125-day voyage towards the Sun, the liquid propulsion systems developed by a key ISRO arm here will play a crucial role in propelling it.

The Sun emits radiation/light in nearly all wavelengths along with various energetic particles and magnetic field. The atmosphere of the Earth as well as its magnetic field acts as a protective shield and blocks a number of harmful wavelength radiations including particles and fields. As various radiations don’t reach the surface of the Earth, the instruments from the Earth will not be able to detect such radiation and solar studies based on these radiations could not be carried out. However, such studies can be carried out by making observations from outside the Earth atmosphere i.e., from space. Similarly, to understand how the solar wind particles and magnetic field from the Sun travel through the interplanetary space, measurements are to be performed from a point which is far away from the influence of the Earth’s magnetic field.
Sun is the nearest star and the largest object in the solar system. It is a hot glowing ball of hydrogen and helium gases.
Age of Sun: The estimated age of sun is about 4.5 billion years.
Distance between Earth and Sun: The distance to the Sun from the earth is about 150 million kilometres, and is the source of energy for the solar system. Without the solar energy the life on earth, cannot exist. The gravity of the sun holds all the objects of the solar system together.
Sun’s parts: At the central region of the sun, known as ‘core’, the temperature can reach as high as 15 million degree Celsius. At this temperature, a process called nuclear fusion takes place in the core which powers the sun. The visible surface of the sun known as photosphere is relatively cool and has temperature of about 5,500 degrees Celsius
