In a significant stride for India's space exploration endeavours, the Indian Space Research Organisation (ISRO) successfully maneuvered its Solar Mission Aditya-L1 into the Halo Orbit, garnering praise from NASA Scientist
Ghosh, reflecting on India's scientific achievements, said, "India is right now in most of the areas where it's scientifically important. And then there is 'Gaganyaan,' which is the human space flight part, that is in the works right now. So, it's been a tremendous stride for the last 20 years. Going from not having a planetary science programme to where we stand today, and particularly after the success of Aditya, it's been a very remarkable journey."
In a significant scientific milestone, Indian Space Research Organisation (ISRO) on Saturday injected Aditya-L1 spacecraft - the first dedicated solar mission - into its final destination orbit.
Prime Minister Narenendra Modi and Minister of State for Science and Technology Jitendra Singh were among leaders who hailed the achievement.
Aditya-L1 has reached Lagrange Point L1, about 1.5 million km from earth.
The PSLV-C57.1 rocket carrying the Aditya-L1 orbiter lifted off successfully from the Satish Dhawan Space Centre in Sriharikota, Andhra Pradesh, in September.
The successful launch of the maiden solar mission of the Indian Space Research Organisation (ISRO) came on the heels of the historic lunar landing mission -- Chandrayaan-3.
Prime Minister Narendra Modi said India will continue to pursue new frontiers of science for the benefit of humanity.
"India creates yet another landmark. India's first solar observatory Aditya-L1 reaches it's destination. It is a testament to the relentless dedication of our scientists in realising among the most complex and intricate space missions. I join the nation in applauding this extraordinary feat. We will continue to pursue new frontiers of science for the benefit of humanity," he said in post on X.
Aditya L1 has seven different payloads on board, to conduct a detailed study of the sun, four of which will observe the light from the sun and the other three will measure in-situ parameters of the plasma and magnetic fields.
The largest and technically most challenging payload on Aditya-L1 is the Visible Emission Line Coronagraph or VELC. VELC was integrated, tested, and calibrated at the Indian Institute of Astrophysics' CREST (Centre for Research and Education in Science Technology) campus in Hosakote in collaboration with ISRO.
This strategic location will enable Aditya-L1 to continuously observe the sun without being hindered by eclipses or occultation, allowing scientists to study solar activities and their impact on space weather in real-time.
Also, the spacecraft's data will help identify the sequence of processes that lead to solar eruptive events and contribute to a deeper understanding of space weather drivers.
Major objectives of India's solar mission include the study of the physics of solar corona and its heating mechanism, the solar wind acceleration, coupling and dynamics of the solar atmosphere, solar wind distribution and temperature anisotropy, and origin of Coronal Mass Ejections (CME) and flares and near-earth space weather.

India's first Sun mission lifted off from the launch pad at Sriharikota on 2 September
India's first solar observation mission is set to reach its final destination in a few hours.
On Saturday, the space agency Isro will attempt to place Aditya-L1 in a spot in space from where it will be able to continuously watch the Sun.
The spacecraft has been travelling towards the Sun for four months since lift-off on 2 September.
It was launched just days after India made history by becoming the first to land near the Moon's south pole.
India's first space-based mission to study the solar system's biggest object is named after Surya - the Hindu god of the Sun, who is also known as Aditya. And L1 stands for Lagrange point 1 - the exact place between the Sun and Earth where the spacecraft is heading.
According to the European Space Agency, a Lagrange point is a spot where the gravitational forces of two large objects - such as the Sun and the Earth - cancel each other out, allowing a spacecraft to "hover".
L1 is located 1.5 million km (932,000 miles) from the Earth, which is 1% of the Earth-Sun distance. Isro recently said that the spacecraft had already covered most of the distance to its destination.
The year India reached the Moon - and aimed for the Sun
How important are India's Moon mission findings?

An Isro official told the BBC that "a final manoeuvre" will be performed on Saturday at around 16:00 India time (10:30 GMT) to place Aditya in L1's orbit.
Isro chief S Somanath has said they will trap the craft in orbit and will occasionally need to do more manoeuvres to keep it in place.
Once Aditya-L1 reaches this "parking spot" it will be able to orbit the Sun at the same rate as the Earth. From this vantage point it will be able to watch the Sun constantly, even during eclipses and occultations, and carry out scientific studies.
Aditya-L1's trajectory
The orbiter carries seven scientific instruments which will observe and study the solar corona (the outermost layer); the photosphere (the Sun's surface or the part we see from the Earth) and the chromosphere (a thin layer of plasma that lies between the photosphere and the corona).
After lift-off on 2 September, the spacecraft went four times around the Earth before escaping the sphere of Earth's influence on 30 September. In early October, Isro said they had done a slight correction to its trajectory to ensure it was on its intended path towards the final destination.
The agency says some of the instruments on board have already started work, gathering data and taking images.
Just days after lift-off, Isro shared the first images sent by the mission - one showed the Earth and the Moon in one frame and the second was a "selfie" that showed two of its scientific instruments.
And last month the agency released the first-ever full-disk images of the Sun in wavelengths ranging from 200 to 400 nanometres, saying they provided "insights into the intricate details of the Sun's photosphere and chromosphere".
India launches its first mission to observe the Sun
What has India's rover been up to on the Moon?
Scientists say the mission will help them understand solar activity, such as the solar wind and solar flares, and their effect on Earth and near-space weather in real time.
The radiation, heat and flow of particles and magnetic fields of the Sun constantly influence the Earth's weather. They also impact the space weather where nearly 7,800 satellites, including more than 50 from India, are stationed.

Scientists say Aditya can help better understand, and even give a forewarning, about solar winds or eruptions a couple of days ahead, which will help India and other countries move satellites out of harm's way.
Isro has not given details of the mission's cost, but reports in the Indian press have put it at 3.78bn rupees ($46m; £36m).
If Saturday's manoeuvre is successful, India will join a select group of countries that are already studying the Sun.
The US space agency Nasa has been watching the Sun since the 1960s; Japan launched its first solar mission in 1981 and the European Space Agency (ESA) has been observing the Sun since the 1990s.
In February 2020, Nasa and ESA jointly launched a Solar Orbiter that is studying the Sun from close quarters and gathering data that, scientists say, will help understand what drives its dynamic behaviour.
And in 2021, Nasa's newest spacecraft Parker Solar Probe made history by becoming the first to fly through the corona, the outer atmosphere of the Sun.
