Aditya-L1 Launch Live Updates: Aditya-L1 has started generating power, solar panels deployed, says Isro

Aditya L1 Mission Launch Live Updates:After Chandrayaan-3, Isro on Saturday kicked off its mission to the Sun with the successful launch of PSLV-C57 carrying Aditya-L1 spacecraft, India’s first solar space observatory. PSLV lifted off from the second launch pad at the Satish Dhawan Space Centre in Sriharikota at 11.50am. It was PSLV’s 59th flight and 25th mission with an XL configuration. The rocket placed 1,480.7kg Aditya-L1 in a highly eccentric Earth-bound orbit in one of the longest launch missions that lasted 63 minutes. The spacecraft will now begin a four-month journey when it will perform orbital maneuvers by using its Liquid Apogee Motor (LAM) to reach the Sun-Earth Lagrange point L1 -- which is 1.5 million km from the Earth -- in a halo orbit.

Aditya L1 Launch: ISRO's Aditya-L1 one of longest PSLV missions ever undertaken

Unlike a regular PSLV launch profile, which places the spacecraft into orbit roughly under 25 minutes from liftoff, Aditya’s separation is projected to happen 63 minutes after the rocket blasts off from the second launch pad in Sriharikota. This will be one of the longest PSLV missions ever undertaken. The February 2021 mission that put Brazil’s Amazonia satellite and 18 others into orbits took more than 1hour and 55 minutes, while the September 2016 mission that put eight satellites into orbits took 2 hours and 15 min utes. Both involved multiple satellites and orbits, unlike Aditya-L1.

What is Aditya-L1 mission

Aditya in Sanskrit means the Sun. Aditya L1 is the first space-based Indian mission to study the Sun. The satellite will be placed in a halo orbit around the Lagrange point 1 (L1) of the Sun-Earth system, which is about 1.5 million km (about 1% of the Earth-Sun distance) from the Earth. As we know, the Sun is a giant sphere of gas and Aditya-L1 will study the outer atmosphere of the Sun. Aditya-L1 will neither land on the Sun nor approach the Sun any closer. The spacecraft will be directed towards the Sun.

Aditya-L1 solar mission: Launch time, where to watch live stream

After landing the Chandrayaan-3 spacecraft on the Moon's south pole, India is now ready to launch its first mission to study the Sun. Called the Aditya L1, this mission is scheduled to launch on Saturday (September 2) at 11.50 am from the Second Launch Pad (SLP) at Satish Dhawan Space Centre, Sriharikota, Andhra Pradesh.

Aditya-L1: 4-month-long journey

Aditya-L1 is the first space-based observatory class

Aditya-L1 is the first space-based observatory class to study the Sun and is being fired using ISRO's reliable Polar Satellite Launch Vehicle (PSLV) from here at 11.50am.

Aditya L1 Launch: With Aditya-L1, India to be among few nations studying Sun

If all goes well with India's Aditya-L1 mission, it will bring India among few countries with probes studying the Sun.

Aditya-L1 solar mission: What is Lagrange point, the location from where Isro studies the Sun

If all goes according to plan, Aditya-L1 will enter into a halo orbit around one of five Lagrange points, areas known as parking spots in space because probes can orbit them in a constant pattern while conserving fuel. From there, Aditya-L1 should enjoy an uninterrupted view of the Sun and study in real time its effect on environmental conditions in the vicinity of earth and other planets. That would count India among the countries with probes studying the Sun.

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.

Aditya L1 Mission Launch: Aditya-L1 will be placed in a halo orbit around Lagrangian Point 1 (or L1)

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.
