In a significant advancement for India’s space exploration efforts, the Indian Space Research Organization (ISRO) successfully maneuvered its solar mission Aditya-L1 into a halo orbit, receiving praise from NASA scientist Amitabh Ghosh.
Reflecting on India’s scientific achievements, Ghosh said, “India is right now in most of the areas where it is scientifically important. And then there is ‘Gaganyaan’, which is part of human space flight, which is in the works right now. So, it has been a tremendous progress over the last 20 years. From not having a planetary science program to where we stand today, and especially after the success of Aditya, it has been a very remarkable journey.”
In a significant scientific milestone, the Indian Space Research Organization (ISRO) on Saturday placed the Aditya-L1 spacecraft – the first dedicated solar mission – into its final destination orbit.
Prime Minister Narendra Modi and Minister of State for Science and Technology Jitendra Singh were among the leaders who lauded the achievement.
Aditya-L1 has reached Lagrange Point L1, about 15 lakh kilometers away from Earth.
The PSLV-C57.1 rocket carrying the Aditya-L1 orbiter successfully lifted off from the Satish Dhawan Space Center in Sriharikota, Andhra Pradesh in September.
The successful launch of the Indian Space Research Organization (ISRO)’s first solar mission comes right after the historic moon landing mission – Chandrayaan-3.
Prime Minister Narendra Modi said India will continue to pursue new areas of science for the benefit of humanity.
“India has achieved another milestone. India’s first solar observatory Aditya-L1 has reached its destination. This is a testament to the tireless dedication of our scientists in realizing the most complex and intriguing space missions. I am proud of this extraordinary achievement. I join the nation in appreciating that we will continue to push new frontiers of science for the benefit of humanity,” he said in the post on Twitter.
To study the Sun in detail, Aditya L1 has seven different payloads, four of which will observe light from the Sun and the other three will measure in-situ parameters of the plasma and magnetic field.
The largest and most technically challenging payload on Aditya-L1 is the Visible Emission Line Coronagraph, or VELC. VELC was integrated, tested and calibrated at the CREST (Centre for Research and Education in Science Technology) campus of the Indian Institute of Astrophysics at Hosakote in collaboration with ISRO.
This strategic location will enable Aditya-L1 to continuously observe the Sun without being interrupted by eclipses or occultation events, allowing scientists to study solar activities and their impact on space weather in real time.
Additionally, data from the spacecraft will help identify the sequence of processes that lead to solar eruption events and will contribute to a deeper understanding of space weather drivers.
The major objectives of India’s Solar Mission include the study of the physics of the solar corona and its heating mechanisms, solar wind acceleration, coupling and dynamics of the solar atmosphere, solar wind distribution and temperature anisotropy, and the origin of coronal mass ejections (CMEs).
