ISRO i.e. Indian Space Research Organization has started the 23 hours 40 minutes countdown for the launch of Solar Mission Aditya L1 on Friday (September 1) at 12.10 pm. Aditya L1 will be launched tomorrow (September 2) at 11.50 am via PSLV XL rocket from Satish Dhawan Space Center in Sriharikota. Before the launch of the mission, ISRO Chief S Somnath reached Chengalamma Parameshwari Temple in Andhra Pradesh on (September 1). Here he prayed for the success of the mission.
Earlier on Monday, August 28, ISRO Chief S Somnath performed puja at Sri Chengalamma Parameshwari Temple in Sullurpeta, Tamil Nadu. He told that before the launch of any mission, ISRO scientists come to this temple. This tradition has been going on for the last 15 years. On August 30, ISRO Chief S Somnath had said that all preparations for the launch of Aditya L1 have been completed. Rocket and satellite are ready. We have also done rehearsals for the launching. The mission will take 125 days to reach the exact radius.
At the same time, ISRO said – the internal checks of the vehicle have been completed. It will reach the Lagrange Point-1 i.e. L1 point, 1.5 million kilometers away from the Earth, in about 4 months. The Aditya spacecraft will move around the L1 point to understand the storms on the Sun. Apart from this, will study things like magnetic field and solar wind. Aditya has 7 payloads for use.
Why will Aditya spacecraft be sent to L1 point only?
Aditya will be placed in a halo orbit between the Sun and the Earth. The orbit around the L1 point is called the halo orbit. ISRO says that a satellite placed in a halo orbit around the L1 point can see the Sun continuously without any eclipse.
With this, real-time solar activities and space weather can also be monitored. Aditya L1’s payload is expected to provide information to understand coronal heating, coronal mass ejections, characteristics of pre-flare and flare activities, movement of particles, and space weather.
What is L1?
The Lagrange point is named after the Italian-French mathematician Joseph-Louis Lagrange. It is commonly known as L-1. There are five such points between the Earth and the Sun, where the gravitational force of the Sun and the Earth gets balanced and centrifugal force is created.
In such a situation, if an object is kept at this place, it easily remains stable between the two and the energy is also less. The first Lagrange point is at a distance of 1.5 million kilometers between the Earth and the Sun. In simple words, L-1 is such a point where any object can remain stable at an equal distance from the Sun and the Earth.
Modi gets emotional after meeting Chandrayaan-3 scientists
Prime Minister Narendra Modi met the scientists of Chandrayaan-3 team at ISRO’s command center on Saturday morning. Here he made 3 announcements. First- Every year on 23rd August, India will celebrate National Space Day. Second- The place where the lander landed on the moon will be called Shiv-Shakti Point. Third- The point on the Moon where Chandrayaan-2’s footprints are, will be named ‘Tiranga’.
