ISRO will launch its first space-based mission Aditya on Saturday. Aditya, designed to study the Sun, will be positioned in a halo orbit around L1 of the Sun-Earth system. Aditya will be carried on PSLV XL rocket and launched from Satish Dhawan Space Centre, Srihorikota, Andhra Pradesh. It is the same place, from where Chandrayaan-3 was launched.
ISRO will place Aditya in a halo orbit around L1, also called Lagrange Point 1, of the Sun-Earth system which is nearly 1.5 million km away from the Earth. ISRO claims that there are major advantages of placing a satellite in the halo orbit around the L1 point. It will allow the scientists to continuously view the Sun without any eclipses/occultation, adding that it will help in real-time observations of the solar activities and their impacts on space weather.
How to watch Aditya Launch?
Aditya is ISRO’s another ambitious space mission after Chandrayaa-3. Interested persons can witness the historic moment by registering on the official theme park website of Satish Dhawan Space Centre. ISRO will announce shortly about the commencement of name registration.
Sullurpeta is the railway station nearest to the launch centre. This station is 18 km away from Srihorikota.
Where to watch Aditya launch live stream?
ISRO is yet to provide online links so that interested people can view the launch of Aditya, India’s first solar mission. However, from the experiences of ISRO’s previous launches, it is sure that the space agency will livestream the event on its official social media handles.

A four-month voyage
Aditya L1 will take nearly four months to reach the Lagrange Point 1. The journey from Srihorikota to L1 point of the Sun-Earth system will involve the following phases.
Launch: The space mission will be launched on September 2 from Srihorikota, Andhra Pradesh
Initial Orbit: Aditya will be initially positioned in a Low Earth Orbit.
Elliptical Orbit: Manoeuvring will be done to make the orbit more elliptical.
Exit from Earth’s Gravitational Sphere of Influence (SOI): Onboard propulsion will be used to propel Aditya towards the L1 point. As the spacecraft approaches towards the L1 point, it will extricate itself from the Earth’s Gravitational Sphere of Influence.
Cruise Phase: The cruise phase of the solar mission will start after it leaves the Earth’s SOI.
Halo Orbit: Aditya will be pushed into a large halo orbit around the L1.
