Aditya-L1, first space-based Indian observatory to study the Sun, is ready for launch! 

The Indian Space Research Organisation (ISRO) made an announcement on X, formerly known as twitter, that the Aditya L-1 satellite has arrived in Sriharikota for integration into its launch vehicle. This would be India's first satellite along the Sun-Earth system.

 Aditya L-1 satellite will be placed in the first Lagranian point of the Sun-Earth system. This vantage offers the scope for a prolonged observation of the sun. Aditya L-1 satellite consists of a Visible Line Emission Coronagraph (VLEC). This has been designed by the Indian Institute of Aerophysics. This took more than 15 years to construct. The VLEC is a solar coronagraph. The objective is to get an image of the solar corona from a distance of slightly more than twice the radius of the sun. The images would have a high resolution and apart from that multiple images can be obtained in a single second. Apart from imaging the VLEC can also perform other functions such as spectroscopy and polarimetry. Apart from the VLEC, the satellite would consist of 6 other instruments. The objective of the mission is multifold. The object of study would include solar emissions, solar winds, coronal mass ejections. 

France, Britain and the United States of America have already established their presence in the first Lagranian point. This was through a joint collaboration between the National Aeronautics and Space Administration (NASA) and the European Space Agency (ESA) . The Matra- Marconi Space built the Solar and Heliospheric Observatory (SOHO) through this collaboration.
