Aditya L1 Solar Mission: After India triumphed in its attempt to successfully soft land a spacecraft in the south polar region of the Moon, it has now turned its attention to the Sun. As the date for the launch of Aditya-L1, India’s first space-based solar mission to gather information related to the Sun, is getting closer, people are getting more and more curious about it. India’s first solar mission Aditya-L1 will be launched from Sriharikota on September 2, 2023. This mission will study the outermost layer of the Sun, the corona. Aditya-L1 will be installed at the Lagrange point L1, about 1.5 million kilometers from Earth.

7 payloads have been prepared for this mission, which will study different aspects of the Sun. One of these payloads will study the Sun’s ultraviolet rays, which are absorbed by Earth’s atmosphere before reaching Earth.

The study of Aditya-L1 will help in better understanding of the Sun’s energy source, prediction of solar storms and space weather. This mission is an important step in India’s space program and will contribute to a better understanding of our planet and the universe.

Some important facts of Aditya-L1 mission –

Launch date: September 2, 2023

Launch Site: Sriharikota, India

Rocket: Polar Satellite Launch Vehicle (PSLV-C57)

Mission Objective: To study the corona, the outermost layer of the Sun

Trajectory : Lagrange point L1

Payloads: 7 payloads, which will study different aspects of the Sun.

Lagrange points are points in space where a smaller body can remain stationary due to the balance of the gravitational forces of two larger bodies. In the Sun–Earth system, there are five Lagrange points: L1, L2, L3, L4 and L5.

The L1 point is located between the Sun and the Earth, at a distance of approximately 1.5 million kilometers from the Earth. It is a fixed point, where any object can be kept in its place with very little effort. Therefore, the Aditya-L1 mission will be set up at the L1 point.

From the L1 point, Aditya-L1 will be able to study the corona, the outermost layer of the Sun. The corona is one of the hottest parts of the Sun, and it is not visible from Earth. The study of Aditya-L1 will help in better understanding of the Sun’s energy source, prediction of solar storms and space weather.

The Aditya-L1 mission is an important step in India’s space programme. It will be an important tool for the study of the Sun, and will contribute to a better understanding of our planet and the universe.

Some important things you should know about Lagrange points –

Lagrange points are caused by the balance of gravitational forces of two massive bodies.

In the Sun-Earth system, there are five Lagrange points

The L1 point is located between the Sun and Earth, approximately 1.5 million kilometers from Earth.

The L1 point is a stable point where an object can be held in place with very little effort.

Aditya-L1 mission to be set up at L1 point

The study of Aditya-L1 will help in better understanding of the Sun’s energy source, prediction of solar storms and space weather.

Seven payloads have been prepared for the Aditya-L1 mission, which will study different layers of the Sun. These payloads include –

• Visible Emission Line Coronagraph (VELC): This payload will study the structure and dynamics of the Sun’s corona by measuring characteristic spectra

• Solar Ultraviolet Imaging Telescope (SUIT): This payload will provide high-resolution images of the outermost layer of the Sun

• Aditya Solar Wind Particle Experiment (ASPEX): This payload will study charged particles emanating from the Sun

• Plasma Analyzer Package for Aditya (PAPA): This payload will study the properties of the Sun’s plasma

• Solar Low Energy X-ray Spectrometer (SoLEXS): This payload will study X-ray rays emanating from the Sun’s corona

• High Energy L1 Orbiting X-ray Spectrometer (HEL1OS): This payload will study high-energy X-ray rays emanating from the Sun

• Advanced Tri-axial High Resolution Digital Magnetometer (ADM): This payload will study the Sun’s magnetic field

Through these payloads, the Aditya-L1 mission will help in better understanding of the source of Sun’s energy, prediction of solar storms and space weather.

Know some important things about the payload of Aditya-L1 mission –

Seven payloads will use electromagnetic, particle and magnetic field detectors

Four payloads will study the Sun directly

Three payloads will conduct in-situ study of particles and fields on L1

These payloads are expected to provide important information about the composition, dynamics and properties of the various layers of the Sun.

Why is the temperature of the Sun’s corona so high? ISRO’s Aditya mission will find out

The VELC satellite, being sent under ISRO’s Aditya mission, aims to find out how the temperature of the Sun’s corona can reach nearly one million degrees, while the Sun’s surface temperature remains a little over 6000 degrees centigrade. The VELC satellite will observe the Sun’s corona and solar chromosphere in UV and X-ray wavelengths. This satellite will also collect information about charged particles and magnetic fields.

The VELC satellite will be placed in a coronal orbit around the L1 point. The L1 point is located between the Sun and the Earth. At this point there is a balance between the gravity of the Sun and the gravity of the Earth. This will help the VELC satellite to continuously keep an eye on the Sun. Data from the VELC satellite will help scientists solve the mystery of the high temperature of the Sun’s corona. This will give scientists a better understanding of solar activity and space weather.
