New Delhi. According to a big news, ISRO has inserted Aditya L1 Spacecraft into Trans-Lagrangian Point 1 at around 2 am. For this, the thrusters of the vehicle have been fired for some time. Let us tell you that, Trans-Lagrangian Point 1 Insertion means that the vehicle has to be sent from the Earth’s orbit towards Lagrangian Point 1. From here this spacecraft will start its journey of 15 lakh kilometers. Now it will reach Lagrangian point 1 after 110 days i.e. in January 2024.
Let us tell you that Aditya L1 was launched into space on September 2 at 11.50 am from the Satish Dhawan Space Center in Sriharikota through the XL version rocket of PSLV-C57. Just 63 minutes and 19 seconds after this spectacular launch, the spacecraft was placed in Earth’s 235 Km x 19500 Km orbit. After this, its orbit was increased four times with the help of thruster fire of the spacecraft.
what is lagrangian point
Let us tell you that, according to scientists, there are five ‘Lagrangian’ points (or parking areas) between the Earth and the Sun, upon reaching which an object stops there. Lagrange points are named after the Italian-French mathematician Joseph-Louis Lagrange, who received a prize for his research paper – ‘Essay sur le probleme des trois corps, 1772. The gravitational force between the Sun and the Earth is balanced at the Lagrange point. This makes it easier to stop a satellite at this point.
Aditya L1 is now collecting scientific data
It is noteworthy that, earlier last Monday, ISRO had informed that Aditya L1 has started collecting scientific data. The Supra Thermal and Energetic Particle Spectrometer i.e. STEPS instrument installed on the spacecraft was activated on September 10, 50,000 kilometers away from the Earth. With the help of data, we will now get information about storms occurring on the Sun and space weather.
Total 6 sensors in STEPS
Let us tell you that the STEPS instrument is part of the Aditya Solar Wind Particle Experiment i.e. ASPEX payload. There are a total of 6 sensors installed in STEPS. Each of these sensors observes in different directions and measures, in addition to electrons greater than 1 MeV, supra-thermal and energetic ions ranging from 20 keV/nucleon to 5 MeV/nucleon.
Aditya has 7 payloads
Let us also tell you that the names of the 7 essential equipments that have gone with the Aditya L1 mission are – Visible Emission Line Coronagraph (VELC), Solar Ultra-Violet Imaging Telescope (SUIT), Aditya Solar Wind Particle Experiment (ASPEX), Plasma Analyst Package for Aditya (PAPA), Solar Low Energy X-ray Spectrometer (SoLEXS), High Energy L1 Orbiting X-ray Spectrometer (HEL1OS) and Magnetometer payload. All of them will contribute greatly to Suraj’s research.
