ISRO: Solar Mission Aditya-L-1 Launched Successfully; Gaganyaan First Flight Trial Lined Up Next

Following the successful launch of the Aditya-L1 orbiter aboard the PSLV-C57.1 rocket from the Satish Dhawan Space Centre in Sriharikota, Andhra Pradesh, Union Minister of State Jitendra Singh announced that the first Gaganyaan trial is expected to take place in October. 

The Indian Space Research Organisation (ISRO) marked this achievement with the successful launch of its inaugural solar mission shortly after the historic lunar landing mission, Chandrayaan-3.

As per the agency's information, the Aditya-L1 mission is projected to arrive at its observation point in four months. It will be positioned in a halo orbit encircling Lagrangian Point 1 (L1), situated 1.5 million kilometers away from Earth in the direction of the sun. 

The mission is equipped with seven distinct payloads designed for an extensive examination of the sun. Among these, four will be dedicated to observing solar light, while the remaining three will be responsible for measuring in-situ parameters of plasma and magnetic fields.

 

The Aditya-L1 mission's largest and most complex payload is the Visible Emission Line Coronagraph (VELC), which was developed, tested, and calibrated in collaboration with ISRO at the Indian Institute of Astrophysics' CREST campus in Hosakote.

This strategic location allows Aditya-L1 to continuously monitor the sun, providing real-time data on solar activities and their impact on space weather, unaffected by eclipses or occultation. The mission's data will help unravel the processes leading to solar eruptive events, contributing to a better understanding of space weather drivers.

India's solar mission aims to investigate the physics of the solar corona, its heating mechanism, solar wind dynamics, solar atmosphere behavior, solar wind properties, Coronal Mass Ejections (CME) and flares, and their influence on near-Earth space weather.

The Union Minister characterized the achievement as a bright moment for India. He drew parallels with the Chandrayaan mission, highlighting the active involvement of the entire nation in this success. He credited Prime Minister Modi for fostering collaboration among stakeholders and stressing that the mission was a collective endeavor for the entire nation.

Additionally, he indicated that the inaugural trial flight of Gaganyaan could potentially occur in October, which was just a month away.

ISRO scheduled the first earth-bound firing to elevate Aditya-L1's orbit for September 3, around 11:45 hours. Aditya-L1 is dedicated to studying the sun comprehensively, seeking to uncover new insights. It will spend 16 days in Earth-bound orbits, performing five manoeuvres to gain the necessary speed.

Subsequently, Aditya-L1 will undertake a 110-day trans-Lagrangian insertion manoeuvre, covering around 15 million kilometers to reach its destination.
