Aditya L1 – ISROs First Sun Mission

Aditya L1 Mission: India’s First Dedicated Solar Mission: The Sun is the source of all life on Earth, but it is also a complex and dynamic body with many mysteries yet unsolved. The Aditya L1 mission is India’s first dedicated solar mission, and it aims to shed light on some of these mysteries by studying the Sun from a unique vantage point.

The Aditya L1 spacecraft will be placed in a halo orbit around the Sun-Earth Lagrange point 1 (L1). This point is located about 1.5 million kilometers away from Earth, and it offers several advantages for studying the Sun. First, L1 is located outside of Earth’s magnetic field, which allows the Aditya L1 spacecraft to observe the Sun without any interference. Second, L1 is located in a region where the gravitational forces of the Sun and Earth are balanced, which means that the Aditya L1 spacecraft can remain in a stable orbit for long periods.

The Aditya L1 mission is expected to provide a wealth of new information about the Sun. This information will help scientists to better understand the Sun’s behavior and how it affects Earth and the solar system.

Aditya L1 launch

The Aditya L1 mission, led by the Indian Space Research Organization (ISRO), marks a historic advancement in solar exploration and has completed its fourth earth-bound manoeuvre. The spacecraft, which was launched on September 2, will make its next manoeuvre on September 19. Aditya-L1 will be set up in a halo orbit, i.e., 1.5 million kilometres from Earth in the sun’s direction. This ground-breaking project attempts to unravel the secrets of the sun’s corona and outer atmosphere and their impact on the climate and environment of space.

Aditya L1 will go to Lagrange Point 1 (L1), located around 1.5 million kilometres from Earth.

Aditya L1 Concepts and Payloads

Aditya-L1 carries seven scientific payloads, all of which have been developed indigenously in India. The payloads are:

1. Visible Emission Line Coronagraph (VELC): VELC is the primary payload on Aditya-L1. It is a coronagraphic instrument that will observe the Sun’s corona in the visible wavelength range. VELC will study the dynamics and structure of the corona, as well as the propagation of solar flares and coronal mass ejections.
2. Solar Ultraviolet Imaging Telescope (SUIT): SUIT is an ultraviolet telescope that will image the Sun’s disk in the near-ultraviolet wavelength range. SUIT will study the chromosphere and transition region of the Sun, as well as the formation and evolution of solar active regions.
3. Solar X-ray Imager (SXI): SXI is an X-ray imaging telescope that will observe the Sun’s corona in the soft X-ray wavelength range. SXI will study the flare heating process and the dynamics of the corona during flares.
4. Solar Low Energy X-ray Spectrometer (SoLEXS): SoLEXS is an X-ray spectrometer that will observe the Sun’s corona in the soft X-ray wavelength range. SoLEXS will study the elemental composition and temperature of the corona, as well as the dynamics of the corona during flares.
5. High Energy L1 Orbiting X-ray Spectrometer (HEL1OS): HEL1OS is an X-ray spectrometer that will observe the Sun’s corona in the hard X-ray wavelength range. HEL1OS will study the particle acceleration process during flares and the dynamics of the corona during flares.
6. Plasma Analyser Package (PAP): PAP is an in-situ payload that will measure the plasma parameters at the L1 Lagrange point. PAP will study the solar wind and its interaction with the Earth’s magnetosphere.
7. Magnetometer (MAG): MAG is an in-situ payload that will measure the magnetic field at the L1 Lagrange point. MAG will study the solar wind and its interaction with the Earth’s magnetosphere.

The science concepts that will be addressed by Aditya-L1 are:

1. Coronal heating: The corona is much hotter than the Sun’s surface, but the mechanism for this heating is not fully understood. Aditya-L1 will study the corona in detail to better understand the coronal heating process.
2. Coronal mass ejections: Coronal mass ejections (CMEs) are large explosions of plasma and magnetic field from the Sun. CMEs can cause space weather disturbances on Earth, such as geomagnetic storms and auroras. Aditya-L1 will study CMEs in detail to better understand their formation and evolution.
3. Solar flares: Solar flares are sudden releases of energy from the Sun. Flares can produce a variety of radiation, including X-rays, UV, and gamma rays. Flares can also cause CMEs. Aditya-L1 will study flares in detail to better understand their formation and evolution.
4. Solar wind: The solar wind is a stream of plasma that flows from the Sun into the solar system. The solar wind interacts with the Earth’s magnetosphere and can cause space weather disturbances. Aditya-L1 will study the solar wind in detail to better understand its interaction with the Earth’s magnetosphere.
