Aditya L1 ISRO’s first solar mission Aditya L1 launched: Will reach Earth orbit in 63 minutes, will reach Lagrange point 15 lakh km away in four months
After the successful landing of Chandrayaan-3 on the south pole of the Moon, ISRO on Saturday sent its first mission to study the Sun. This mission named Aditya L1 was launched at 11.50 am from the Satish Dhawan Space Center in Sriharikota through the XL version rocket of PSLV-C57. PSLV is a four stage rocket.
Aditya L1 will be launched by the rocket into an orbit of 235 x 19500 kilometers. It will take 63 minutes 19 seconds. After about 4 months, this spacecraft will arrive at Lagrange Point-1 (L1). Since there is no eclipse at this location, it is simple to study the Sun from here. This mission is expected to cost 378 crore rupees.
Aditya L1 will reach Lagrange point (L1) in four months
It will take about 125 days i.e. 4 months for Aditya Spacecraft to reach L1 point. The 125-day period will end on January 3, 2024. If the mission is successful and Aditya spacecraft reaches Lagrangian point 1, then it will be a big achievement for ISRO in the new year.
What is Lagrange Point-1 (L1)?
The Lagrange point is named after the Italian-French mathematician Joseph-Louis Lagrange. It is colloquially known as L1. 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. There are 1.5 million kilometers between the Earth and the Sun, where the first Lagrange point is located.
Eclipse at L1 point neutralized, sending here
Between the Sun and the Earth, Aditya Yan will be positioned in the Halo Orbit. According to ISRO, a satellite positioned in a halo orbit around the L1 point may continuously observe the Sun without experiencing any eclipses. This allows for the monitoring of solar activity in real time as well as space weather.
7 equipments fitted in Aditya L1 will understand the sun
By sticking at L1, or level one, Aditya Yan will comprehend the storms developing on the Sun. Lagrangian point of Sun-Earth. It will test the orbit around the Lagrangian point, photosphere, chromosphere and the outermost layer of the corona through different web bands through 7 instruments.
Aditya L1’s seven instruments will provide
information on coronal heating, coronal mass ejection, characteristics of pre-flare and flare activities, movement of particles and space weather. The solar corona and its heating mechanism will be studied by Aditya L-1.
7 payloads being sent with Aditya L1
The names of the payloads i.e. equipment sent with 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). , High Energy L1 Orbiting X-ray Spectrometer (HEL1OS), Solar Low Energy X-ray Spectrometer (SoLEXS), and Magnetometer payload.
- The dynamics of the solar corona and coronal mass ejections will be investigated using the Visible Emission Line Coronagraph (VELC) instrument.
- The Solar Ultra-Violet Imaging Telescope (SUIT) instrument will take pictures of the solar photosphere and chromosphere at near ultraviolet wavelengths and study changes in solar irradiance (light energy coming from the Sun to Earth).
- Energy particles and the solar wind will be studied by the Aditya Solar Wind Particle Experiment (ASPEX) and Plasma Analyzer Package for Aditya (PAPA) instruments. Additionally, the energy distribution of these particles will be studied using this payload.
- The Solar Low Energy X-ray Spectrometer (SoLEXS) and the High Energy L1 Orbiting X-ray Spectrometer (HEL1OS) will study the Sun’s X-ray flares over a wide X-ray energy range.
- The magnetic field between the planets at the L1 point will be investigated by the magnetometer apparatus.
Aditya L1 was completely made in the country
Aditya L1 is a totally domestic project, involving collaboration from national institutions, according to an ISRO official. Its payload was created by the Visible Emission Line Coronagraph at the Indian Institute of Astrophysics (IIA), Bengaluru. The Solar Ultraviolet Imager payload for the mission has been designed by the Inter-University Center for Astronomy and Astrophysics Pune.
Why is the study of the Sun necessary?
Our solar system, which contains the Sun, is in its core. All the eight planets revolve around the Sun. The Sun is responsible for supporting life on earth. Energy flows continuously from the Sun. We call them charged particles. By studying the Sun, it can be understood how changes in the Sun can affect space and life on Earth.
13 lakh earths will merge into the sun: explosions equal to 1 lakh crore nuclear bombs every second; Aditya-L1 will find out its secrets
The sun Is so huge that 1.3 million earths can fit in it. It is so hot that even the energy released by the explosion of 1 lakh crore atomic bombs fades away. The Sun is 460 crore years old and is likely to remain so for the next 1,000 crore years. Today at 11:50 am, India’s solar mission Aditya L1 will set out to explore the secrets of the Sun.
