Aditya L1 Successfully Launched, India's Solar Mission In Space

Updated: Saturday, September 2, 2023, 16:35 [IST]

After the successful Chandrayaan-3 mission, the ISRO on Saturday launched the Aditya-L1 spacecraft at 11:50 am from the Sriharikota spaceport.

Aditya-L1 spacecraft is designed to provide remote observations of the solar corona and in-situ observations of the solar wind at L1 (Sun-Earth Lagrangian point), which is about 1.5 million kilometres from the Earth.

It will be the first dedicated Indian space mission for observations of the Sun to be launched by the Bengaluru-headquartered space agency.

The space agency said in a social media post that the spacecraft -- the first space-based Indian observatory to study the Sun -- would be launched by PSLV-C57 rocket.

Scientists expect to get new information about the past, present and future of the Sun after analysing the data that will be collected by India's first solar mission Aditya-L1

Aditya-L1 will go up to the First Lagrangian point, about 1.5 million km from the Earth, and transmit the data much of which will come to the scientific community for the first time from a platform in space, said solar physicist Prof Dipankar Banerjee, who is part of a team which conceptualised the mission more than 10 years ago.

"Our existence or life on Earth is basically because of the presence of the Sun which is our nearest star. All energy comes from the Sun. It is important to understand whether it is going to emit the same radiation (that it does now) or it is going to undergo changes: Solar physicist Prof Dipankar Banerjee.

On India's space missions, former Commander of the International Space Station and author of the Apollo Murders, Chris Hadfield says, "...All of this space commerce, GPS satellites, weather satellites, telecommunications, exploring the Moon, exploring the Sun, all of that has happened in less than one lifetime. So it's not so much a space race as it is a new space opportunity for everybody. Now the race is really about who can push the technology in an economic way to turn it into profitable space businesses for each of the companies and each of the countries involved. India is in a really strong leveraged position to do that. I think Prime Minister Narendra Modi has seen that for several years. He is very much directly involved with the Indian space and research organization...So it's a really smart move on India's leadership's part right now, to be pushing it, to be developing it, but also being in the process of privatizing it so that the businesses and therefore the Indian people can benefit."

On the budget of India's Moon Mission (Chandrayaan-3), former Commander of the International Space Station and author of the Apollo Murders, Chris Hadfield says, "It's really important to put the budget into perspective...If you compare it to everything else that the Indian government is doing, if you compare it to the amount that's spent on food distribution or the rest of health and welfare for the Indian people, it is like a 100th of 1% of the whole budget...In comparison to what other countries spend in order to do something similar, it's one of India's great strengths as well...It makes them (India) extremely competitive...The inexpensive and successful way that India landed on the Moon, is proof positive for all of those Indian space companies that they can do something as well and for a lot less money than the rest of the world and that is a really good business model."

On this day in the last century, the worst solar event that has ever happened blasted the Earth. A huge blob of energy, of high energy particles smashed into the Earth...It actually set telegraph machines on fire. That's going to happen again. So when we put something like Aditya L-1 up there in between us and the Sun to sense those things, to better understand how the sun works and the threats that it has to the earth, it's good for everybody, for protecting us as people...So, it's a really good new scientific probe to have out there teaching us about the Sun."

So, putting a new sensor in between us and the Sun, that is looking specifically at how the sun sends out these big damaging ejections of high-energy particles, is really useful information, not just for ISRO and not just for the Indian space program, but it's something that is sort of vital..."
