ISRO to get Aditya L-1 payload on Republic Day


On Republic Day, the Indian Space Research Organization (ISRO) will receive a sizable payload that is a component of India’s first solar mission. At a ceremony at Hosakote, the Visible Line Emission Coronagraph (VLEC) will be presented to ISRO by the Indian Institute of Astrophysics (IIA).

One of the mission’s main components, the payload, has been in development for more than five years. Solar physicists from all across India have contributed their expertise to the process of conceptualizing, designing, and developing the payload. The mission’s final phases officially start with the handover.

The VLEC was built to carry out imaging and spectroscopy in order to discover the solar corona’s mysteries. One of the most challenging aspects of studying a star is its corona, which is its outermost layer. Since the corona is obscured by the disc and is therefore invisible, it can only be studied during an eclipse. The corona is around 10 million times less thick than the Sun’s surface, and because of this low density, it is far less luminous than the Sun’s surface.


The remaining three payloads conduct in-situ investigations of particles and fields at the Lagrange point L1, while four payloads observe the Sun directly from the exceptional vantage point of L1.

ISRO is prepared to undergo a series of tests to check its launch parameters once it receives the cargo. To validate its launch designs, the ISRO team will subject it to a number of crucial tests like vibration, acoustic, and pressure tests.

Midway through 2023, the Aditya L1 mission will launch to Lagrange Point 1. (L1). The Solar and Heliospheric Observatory Satellite SOHO from NASA is now based at the L1 point of the Earth-Sun system, which offers a continuous view of the sun. The advantage of regularly watching solar activity is greater from this position.
