The mission is expected to last five years. During this time, the satellite will orbit around L1 in an irregularly shaped orbit, perpendicular to the line joining Earth and the Sun.
Aditya L1 Launch highlights: Aditya-L1 blasted off from Sriharikota at 11.50 am. Aditya L1 will take an approach similar to Chandrayaan-3 to reach its designated spot. The total journey time for ISRO's Aditya-L1 solar mission from Sriharikota (Earth) to L1 is estimated to be about four months.
The mission is expected to last five years. During this time, the satellite will orbit around L1 in an irregularly shaped orbit, perpendicular to the line joining Earth and the Sun.
The first Earth-bound firing for the craft's orbit jump is scheduled for around 11.45 am tomorrow.
"Aditya L1 spacecraft has been injected in an elliptical orbit of 235 by 19,500 km which is intended, very precisely by the PSLV," he said.
Prime Minister Narendra Modi congratulated ISRO for the successful launch of Aditya L1, India's first space-based solar observatory, from Sriharikota, Andhra Pradesh on Saturday. "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," he posted on X.
Aditya L1 has been successfully injected in the right orbit, said ISRO chief. India’s first solar observatory has begun its journey to the destination of Sun-Earth L1 point, which will be 125 days
Aditya L1 has separated from the upper stage of the PSLV rocket.
All signals are healthy for the satellite to be injected into an eccentric Earth-bound orbit. Aditya L1 spacraft will soon enter the first of many Earth orbits before it heads to designated L1 point.
ISRO's range operations director confirmed that the second burn of the PS4 stage has commenced.
According to Anil Bharadwaj, Director of Physical Research Laboratory, India is the third country to have a mission at L1. "You don’t have such a satellite existing in L1 point so far,” he said.
Annapurni Subramaniam, director of Indian Institute of Astrophysics, said the mission will be the first to probe into the innermost part of the Sun, the Corona. "We have boarded the main instrument on board the launch vehicle carrying Aditya L1. It is the Visible Line Emission Coronagraph (VELC). It will enable an unobstructed view of the Sun."
Aditya L1's objective will be to study disturbances in the form of solar flares or solar winds directed towards Earth, which can adversely impact space weather.
Aditya L1 first space-based observatory to study the Sun. After travelling for about 1.5 million km from the Earth over 125 days it will be placed in a Halo orbit around the Lagrangian point L1, a glitch-free spot close to the star.
