ISRO chief S. Somnath on April 21 said that the Aditya L1 solar mission of the premier space research agency is continuously sending data about the Sun.

Mr. Somnath, who was speaking to reporters here after being conferred a special award by jewellery major P.C. Chandra Group, said several instruments of the spacecraft are working continuously to feed data on many aspects.

“We are looking into the sun in a continuous manner – UV magnetic charges observation, corona graph observation, X-ray observation and other things,” he said.

India’s first solar mission craft, Aditya-L1 spacecraft was launched on September 2, 2023.

“As we are keeping this satellite for five years, the observation will be analysed as a long-term measure. It is not like your instant news that something has been reported about the sun today, something else will happen tomorrow, things will happen every day,” he explained.

All observations will happen now but the results will be known later, he said.

“Eclipse happens as the sun is blocked by the moon. It is not like that anything happens within the sun during an eclipse. But obviously, our mission is also collecting data about the sun before, during and after an eclipse, Mr. Somnath said, while answering a question on whether the mission will throw light on the solar eclipse.

Speaking about collaborations with other space agencies, he said ISRO is building a joint satellite NISAR (NASA-ISRO Synthetic Aperture Radar).

A day after India’s first solar observatory mission which was launched, the first Earth-bound firing to raise the orbit of the Aditya-L1, was performed on Sunday.

The ISRO Telemetry, Tracking and Command Network Work (ISTRAC) in Bengaluru performed the manoeuvre.

The space agency said the satellite is healthy and operating nominally. “The first Earth-bound maneuvre (EBN#1) is performed successfully from ISTRAC, Bengaluru. The new orbit attained is 245km x 22459 km. The next maneuvre (EBN#2) is scheduled for September 5, 2023, around 03:00 Hrs. IST,” ISRO posted on X (formerly Twitter).

Post its successful launch ISRO said that the Aditya-L1 started generating the power and that the solar panels are deployed.

Following the launch Aditya-L1 stays Earth-bound orbits for 16 days, during which it undergoes 5 manoeuvres to gain the necessary velocity for its journey.

Subsequently, Aditya-L1 undergoes a Trans-Lagrangian1 insertion manoeuvre, marking the beginning of its 110-day trajectory to the destination around the L1 Lagrange point.

Upon arrival at the L1 point, another manoeuvre binds Aditya-L1 to an orbit around L1, a balanced gravitational location between the Earth and the Sun.

The satellite spends its whole mission life orbiting around L1 in an irregularly shaped orbit in a plane roughly perpendicular to the line joining the Earth and the Sun.

In a significant leap for the country’s space exploration endeavours, the Indian Space Research Organisation (ISRO) on Saturday successfully launched its maiden solar mission, Aditya-L1, carrying seven payloads for a detailed study of the sun.

India’s first solar space observatory mission was launched on the Polar Satellite Launch Vehicle (PSLV) XL from the Satish Dhawan Space Centre in Sriharikota at 11.50 am. The separation of Aditya-L1 and its injection into an elliptical orbit around the Earth were successful and took about 63 minutes.

Several politicians across party lines congratulated ISRO on the successful launch of the mission and its importance for science and humanity.

President Droupadi Murmu celebrated the significant milestone as a “historic feat,” underscoring its contribution to expanding our understanding of outer space. She conveyed her sincere congratulations to the dedicated ISRO scientists and engineers for their outstanding achievement and offered her utmost support for the mission’s prosperous outcome.

“The launch of Aditya-L1, India’s first solar mission, is a landmark achievement that takes India’s indigenous space programme to a new trajectory. It will help us better understand space and celestial phenomena. I congratulate the scientists and engineers at ISRO for this exceptional feat. My best wishes for the success of the mission,” President Murumu said.

Appreciating the hardworking scientists responsible for this extraordinary accomplishment in India’s space exploration journey, Prime Minister Narendra Modi conveyed his confidence in India’s continued efforts to enhance our “understanding of the universe for the welfare of entire humanity.”

“After the success of Chandrayaan-3, India continues its space journey. Congratulations to our scientists and engineers at ISRO for the successful launch of India’s first Solar Mission, Aditya -L1. Our tireless scientific efforts will continue in order to develop a better understanding of the universe for the welfare of entire humanity,” PM Modi said.

The main opposition party in the Indian parliament, Congress, hailed the launch of Aditya-L1 as a “stupendous achievement” for India, as it shared a timeline of the mission from its conceptualization for understanding the “continuity in the ISRO saga”.

In a post in Hindi on X, the Congress said ISRO has given many opportunities to the country to be proud.

“After Chandrayaan-3, ISRO has again raised the nation’s prestige by successfully launching Aditya L-1,” the party said.

ISRO ने देश को गौरवान्वित होने के अनेक मौके दिए हैं।

चंद्रयान-3 के बाद ISRO ने आदित्य L-1 को सफलतापूर्वक लॉन्च कर फिर से देश का मान बढ़ाया है।

देश के वैज्ञानिकों की इस अभूतपूर्व उपलब्धि पर समस्त कांग्रेस परिवार को गर्व है। ISRO की पूरी टीम को शुभकामनाएं।

The entire Congress family is proud of this unprecedented achievement of the country’s scientists, it said.  Best wishes to the entire ISRO team, the party added.

In a post on X, Congress general secretary Jairam Ramesh said, “Today’s launch of Aditya-L1 is another stupendous achievement of ISRO and for India!” “While saluting ISRO once again, it is worthwhile recalling the recent timeline for Aditya-L1 to understand the continuity in the ISRO saga,” he said.

According to ISRO, Aditya-L1 is the first space-based observatory to study the Sun. The spacecraft, after travelling about 1.5 million km from the Earth over 125 days, is expected to be placed in a Halo orbit around the Lagrangian point L1 which is considered closest to the Sun.

For launching its Aditya-L1 mission on September 2, the Indian Space Research Organisation (ISRO) will be using a variant of the Polar Satellite Launch Vehicle (PSLV) which also launched India’s first missions to the moon and Mars.

With the PSLV-C57/Aditya-L1 mission, India’s first solar mission, the PSLV-XL variant will mark its 25th flight.
