After the successful Chandrayaan-3 lunar mission, ISRO is now gearing up for the launch of a solar mission in a week's time, likely on September 2, to study the Sun.
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, reported PTI.
It will be the first dedicated Indian space mission for observations of the Sun to be launched by the Bengaluru-headquartered space agency, it said.
The Aditya-L1 mission, aimed at studying the Sun from an orbit around the L1, would carry seven payloads to observe the photosphere, chromosphere and the outermost layers of the Sun, the corona, in different wavebands, the report said.

Aditya-L1 is a fully indigenous effort with the participation of national institutions, an ISRO official said, the report said.
The Bengaluru-based Indian Institute of Astrophysics (IIA) is the lead institute for the development of Visible Emission Line Coronagraph payload. While Inter-University Centre for Astronomy and Astrophysics, Pune, has developed the Solar Ultraviolet Imager payload for the mission, it said.
Aditya-L1 can provide observations on the corona, and on the solar Chromosphere using the UV payload and on the flares using the X-ray payloads, it mentioned.
The particle detectors and the magnetometer payload can provide information on charged particles and the magnetic field reaching the halo orbit around L1, it stated.

The satellite, realised at U R Rao Satellite Centre, arrived at the ISRO's spaceport of Sriharikota in Andhra Pradesh, two weeks ago, it said.
"Most likely the launch will take place on September 2 ", an ISRO official said, as per the report.
The spacecraft is planned to be placed in a halo orbit around the L1 of the Sun-Earth system.
A satellite placed in the halo orbit around the L1 point has the major advantage of continuously viewing the Sun without any occultation/eclipses, ISRO noted.
"This will provide a greater advantage of observing the solar activities and its effect on space weather in real time," it said.
Using the special vantage point L1, four payloads directly view the Sun and the remaining three payloads carry out in-situ studies of particles and fields at the L1, thus providing important scientific studies of the propagatory effect of solar dynamics in the interplanetary medium.
"The suits of Aditya L1 payloads are expected to provide most crucial informations to understand the problem of coronal heating, coronal mass ejection, pre-flare and flare activities and their characteristics, dynamics of space weather, propagation of particle and fields etc", ISRO said.
