Aditya L1 Mission

Aditya L1 Mission : India’s first solar mission, Aditya-L1 was successfully launched from Satish Dhawan Space Centre in Sriharikota, Andhra Pradesh, at 11.50am on Saturday.
India’s solar mission comes close on the heels of its successful lunar endeavour — Chandrayaan-3. With Aditya-L1, Isro will venture into the study of solar activities and its effect on space weather.

Following the success of Chandrayaan-3, the Indian Space Research Organisation has launched its new mission, Aditya-L1, to study the Sun at 11:50 am from the Sriharikota spaceport. The mission will travel 1.5 million kilometres to study about the earth’s closest star over the course of five years. The spacecraft — the first space-based Indian observatory to study the Sun — would be launched by PSLV-C57 rocket. This mission is a collaboration between ISRO and several esteemed institutions.

Aditya-L1 is India’s first solar mission, designed to conduct very important scientific studies of the Sun. The data provided by this will be used to find out how the temperature of the corona reaches almost one million degrees Celsius, while the temperature on the surface of the Sun remains a little over 6000 degrees centigrade. Aditya-L1 will give information about the Sun’s corona and solar chromosphere. This will be done using UV payloads.

Aditya-L1: ISRO today successfully launched India’s first solar mission Aditya-L1 at 11.50 am. Aditya-L1 was launched from PSLV-C57 rocket. PSLV will place Aditya-L1 in Earth’s orbit. From where the Aditya-L1 spacecraft will raise its orbit several times using the powerful engines of its Liquid Apogee Motors (LAM). Which will take Aditya-L1 to its destination – approximately 15 lakh km. Will play a big role in reaching the distant Lagrange Point-1 (L1). This is 1/100th of the distance between the Earth and the Sun.

India’s first solar mission AdityaL1 successfully launched

The Aditya L1 rocket will launch into low Earth orbit. After about 63 minutes 19 seconds, the spacecraft will reach the orbit of 235 x 19500 Km. Aditya spacecraft will reach Lagrange Point-1 (L1) after about 4 months. There is no effect of eclipse on this point, due to which the Sun can be easily studied from here. The estimated cost of this mission is Rs 378 crore.

Former chief of ISRO G. Madhavan Nair said – Aditya L-1 is very important

Former chairman of ISRO G. Madhavan Nair said that ISRO’s first solar mission is very important. Aditya L-1 will be placed around the Lagrangian point 1, where the gravitational force of the Earth and the Sun almost vanishes. With minimum fuel we can maintain the spacecraft there. Apart from this it is possible to see the sun continuously from there. Seven instruments have been installed in the spacecraft. The data from this mission will help in understanding various phenomena occurring in the atmosphere, climate change studies etc.
