On September 5, giving an update about Aditya L1 spacecraft, India’s first solar mission the Indian Space Research Organisation (ISRO) said that, “Aditya L1 Mission, The second Earth-bound maneuvre (EBN#2) is performed successfully from ISTRAC, Bengaluru. ISTRAC/ISRO’s ground stations at Mauritius, Bengaluru and Port Blair tracked the satellite during this operation. The new orbit attained is 282 km x 40225 km,” ISRO said in a post on ‘X’ in the early hours of September 5.
“The next manoeuvre (EBN#3) is scheduled for September 10, around 02:30 Hrs. IST,” ISRO added.

After the successful landing of Chandrayaan 3 near the South pole of the moon, the ISRO launched the country’s maiden solar mission — Aditya L1 from the Satish Dhawan Space Centre in Sriharikota on September 2.
It carried seven different payloads to have a detailed study of the sun, four of which will observe the light from the sun and the other three will measure in-situ parameters of the plasma and magnetic fields.
Aditya L1 will be placed in a halo orbit around Lagrangian Point 1 (or L1), which is 1.5 million km away from the Earth in the direction of the sun. It is expected to cover the distance in four months’ time.Aditya L1 will stay approximately 1.5 million km away from Earth, directed towards the Sun, which is about 1 per cent of the Earth-Sun distance. The Sun is a giant sphere of gas and Aditya L1 would study the outer atmosphere of the Sun.
ISRO said Aditya-L1 will neither land on the sun nor approach the sun any closer.
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.
Major objectives of India’s solar mission include the study of the physics of solar corona and its heating mechanism, the solar wind acceleration, coupling and dynamics of the solar atmosphere, solar wind distribution and temperature anisotropy, and origin of Coronal Mass Ejections (CME) and flares and near-earth space weather.
Aditya L1 is a satellite dedicated to the comprehensive study of the sun, which will find out the unknown facts about the sun. The satellite will travel on Earth-bound orbits for 16 days, during which it will undergo five manoeuvres to gain the required speed to reach its destination.
Subsequently, Aditya-L1 will undergo a trans-Lagrangian1 insertion manoeuvre that will take 110 days. The satellite will travel approximately 15 million kilometres to reach the L1 point. Upon arrival at the L1 point, another manoeuvre binds Aditya L1 to an orbit around L1, a balanced gravitational location between the Earth and the Sun, according to information shared on ISRO’s official website.
