Aditya L1 Launched | Aditya L1 reaches Earth’s ‘Orbit’, PSLV C-57 mission completed, ‘Spacecraft’ will reach L1 point in 110 days. Presswire18 (News)


New Delhi/Sriharikota, Today, the Indian Space Research Organization (ISRO) successfully launched the country’s first Sun mission ‘Aditya L1’ from the space center here on Saturday with the aim of creating history once again after a successful ‘soft landing’ on the Moon a few days ago. . ISRO today informed that the Aditya-L1 vehicle has been successfully separated from the PSLV rocket. This mission of India will help in removing the veil from the mysteries related to the Sun.

ISRO officials said as the 23.40-hour countdown came to an end, the 44.4-metre-tall Polar Satellite Launch Vehicle (PSLV) rocketed into the skies on schedule at 11.50 am from the space center at Sriharikota, about 135 km from Chennai. Happened. The rocket released Aditya into an orbit of 235 x 19500 Km after 63 minutes 19 seconds. After about 4 months it will reach Lagrange point-1. There is no effect of eclipse at this point, due to which research on the sun can be done easily from here.

Understand the journey of Aditya L1 in 4 easy points

  • Aditya L1 will orbit the Earth for 16 days. Will raise the orbit by firing the thruster 5 times.
  • After this Aditya’s thrusters will fire again and it will move towards the L1 point.
  • And after traveling for 110 days, the Aditya Observatory will reach near this point.
  • With this, Aditya will be successfully placed in the orbit of L1 point through thruster firing.

What is Lagrangian point

Let us tell you that, according to scientists, there are five ‘Lagrangian’ points (or parking zones) between the Earth and the Sun, reaching which an object stops there. Lagrange points are named after the Italian-French mathematician Joseph-Louis Lagrange for his prize-winning research paper ‘Essay sur le problem des trois corps, 1772’. The gravitational force between the Sun and the Earth at a Lagrange point is balanced, making it easy to intercept a satellite at this point.

Let us inform that, by achieving success in ‘soft landing’ on the South Pole region of the Moon on August 23 last month, India has become the first and so far the only country in the world to create such a record. ‘Aditya L1’ will conduct various types of scientific studies to know the secrets of the Sun as well as send its pictures to Earth for analysis.

Why the name of Surya mission is ‘Aditya-L1’

Significantly, the Sun mission has been named ‘Aditya-L1’ because it will carry out its study work by staying in the Lagrangian point 1 (L1) region, 1.5 million kilometers away from Earth. ISRO said that Aditya-L1 will take about four months from launch to reach the L1 point.

Explaining the reason for studying the Sun, ISRO said that it emits radiation in almost all wavelengths along with various energy particles and magnetic fields. Earth’s atmosphere and its magnetic field act as a protective shield and block harmful wavelength radiation. Solar studies are done from space to detect such radiation. The major objectives of the mission include studying the heat of the Sun’s corona and the solar wind, earthquakes on the Sun or ‘Coronal Mass Ejections’ (CMEs), space weather near the Earth, etc.

Learn the names and functions of 7 equipments of ‘Aditya-L1’

The ‘Aditya-L1’ satellite carried seven scientific instruments to carry out the study. Of these, the ‘Visible Emission Line Coronagraph’ (VELC) will study the Sun’s corona and the dynamics of CMEs. VELC is the primary instrument of the vehicle, which will send 1,440 images per day to the center on Dhamti for analysis once it reaches the desired orbit. It is the ‘largest and most technically challenging’ instrument on Aditya-L1. The Solar Ultraviolet Imaging Telescope will take pictures of the Sun’s photosphere and chromosphere and measure solar radiation variations.

So the instruments named ‘Aditya Solar Wind Particle Experiment’ (ASPEX) and ‘Plasma Analyzer Package for Aditya’ (PAPA) will study the solar wind and energy ion as well as energy distribution. The ‘Solar Low Energy X-ray Spectrometer’ and the ‘High Energy L1 Orbiting X-ray Spectrometer’ (HEL1OS) will study X-ray flares from the Sun in a wide X-ray energy region. An instrument called ‘magnetometer’ is capable of measuring the interplanetary magnetic field at point ‘L1’. The instruments on ‘Aditya-L1’ have been developed indigenously in collaboration with various centers of ISRO.
