Sriharikota: India achieves another feat after historic Chandrayaan-3 touchdown. India’s maiden solar expedition Aditya-L1 mission onboard PSLV C57 lifts off from Sriharikota. A large number of people are present at Satish Dhawan Space Center (SDSC) SHAR Sriharikota to watch the launch of ISRO’s Sun Mission Aditya L-1. Aditya L1 will take about 4 months to reach close to the Sun. Aditya L1 will cover a distance of about 1.5 million kilometers from the earth. The solar mission reportedly costs over ₹ 300 crores.
The work of this mission will be to study the temperature and dynamics of the Sun. It will help protect India’s 50+ satellites. The separation of Aditya-L1 is expected to take about 63 minutes.
ISRO said that Aditya-L1 will be placed in a halo orbit around the Lagrangian point 1 (L1), 1.5 million km from Earth, in the direction of the Sun. The satellite and payload will revolve around the Sun in the same relative position and will see the Sun continuously without any eclipse. This will help in observing the solar activities and their effect on space weather in real time.
With the help of this mission, ISRO will study factors like corona, the outer layer of the Sun, coronal mass ejections (powerful explosions in the Sun), origin of solar storms, pre-flare and flare activities and their characteristics. In addition, information on the effect of the Sun’s movements on space weather will also be gathered.
ISRO’s Aditya L1 is the first Sun mission to reach the L1 point. The distance of this place from the earth is 1.5 million kilometers. Aditya L1 will study the Sun’s rays and will stay here for 5 years 2 months. Rs 378 crore will be spent on this work.
Significantly, the Sun is the closest star to the Earth. It is possible to study the Sun in comparison to other stars. After this mission, it will be possible to study the rest of the stars of the Milky Way and information about the stars of other Galaxy is possible. The distance of the sun is about 15 crore kilometers and its temperature is 10 to 20 lakh degree Celsius. Its age is 4.5 billion years.
Aditya-L1 will send the first picture of the vehicle in February. According to scientists, the vehicle will send one picture every minute, that is, 1440 pictures will be available for study in 24 hours. This vehicle is going to send pictures for the next five years.
Seven payloads have been installed in this vehicle, in which the largest and challenging payload is VELC. This payload will send all the pictures to Earth. The VELC payload has been the largest and most technically challenging payload on Aditya-L1.
PM Modi congratulates ISRO over India’s first solar mission launch
After the success of Chandrayaan-3, India continues its space journey.
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 better…
