Aditya L1 Mission : Weeks after creating history by landing on the South Pole of the Moon, ISRO is all set to launch Aditya L1, its spacecraft to study Sun, on September 2 at 11:50 am from Sriharikota.
ISRO in a post said the countdown for the event has been started .
Aditya L1 will travel 1.5 million km from Earth to Lagrange 1 or L1 point, between the Earth and Sun, four times the distance travelled by the Chandrayaan missions.

NASA's Parker Probe touched the Sun for the first time in history in 2021. The probe navigated Sun's upper atmosphere, known as the corona, and sampled particles and magnetic fields within.
Aditya L1 mission live: Aiming for a clean launch
The scientific payloads in Aditya L1 can’t afford to have even a micron (one-millionth of a metre) size dust particle. ISRO has completely refurbished the craft and reportedly counted the particle size to the lowest level possible.
Aditya L1 mission live: What will be ISRO objectives?
The ISRO has listed the following major science objectives of Aditya-L1 mission:
-- Study Solar upper atmospheric (chromosphere and corona) dynamics.
-- Study chromospheric and coronal heating, physics of the partially ionized plasma, initiation of the Coronal Mass Ejections, and flares
-- Observe the in-situ particle and plasma environment to understand particle dynamics from the Sun.
-- Assess physics of solar corona and its heating mechanism
-- Study coronal and coronal loops plasma: Temperature, velocity and density.
-- Identify the sequence of processes that occur at multiple layers (chromosphere, base and extended corona) which eventually leads to solar eruptive events
-- Magnetic field topology and magnetic field measurements in the solar corona.
Aditya L1 Mission LIVE: Help from ESA
ESA is providing deep space communication services to the mission via there 35-metre deep space antennas in Australia, Spain and Argentina. It is main provider of ground station services for Aditya-L1. ESA stations will support the mission from beginning to end: from the critical ‘Launch and Early Orbit Phase’, throughout the journey to L1
Aditya L1 Mission LIVE: The seven instruments of Aditya
The craft's seven instruments will investigate open questions about the Sun. Four of them will view the Sun directly, while the other three will carry out in-situ measurements to explore the nature of the space weather that the Sun generates in interplanetary space.
Aditya L1 Mission LIVE: Guess who will be our neighbour
While L1 will be inhabited by Aditya, L2 is home to the James Webb Space Telescope since early last year.
Aditya L1 Mission LIVE: All about Lagrange points
There are five Lagrange points in all. L4 and L5 are seen as stable, L1, L2, and L3 are considered ‘unstable’. Nasa says L1 and L2 points are unstable on a time scale of approximately 23 days, which requires satellites orbiting these positions to undergo regular course corrections.
Aditya L1 Live Updates: The money spent on this mission
The government sanctioned the equivalent of about $46 million for the mission in 2019.
ISRO has not given an official update on costs. India has achieved a reputation for successful space launches at cut-throat costs. It's latest moon mission had a budget of about $75 million- less than that of Hollywood space thriller "Gravity".
