Unlocking the Secrets of the Sun: ISRO’s ADITYA L1 Mission

Unveiling the Sun’s Mysteries: ISRO’s Aditya-L1 Mission Set for September 2 Launch


In a remarkable leap towards the stars, the Indian Space Research Organisation (ISRO) is gearing up for the launch of its maiden space observatory for solar research – the Aditya-L1. Scheduled for liftoff on September 2, this mission promises to shed light on the sun’s enigmatic atmosphere, paving the way for groundbreaking discoveries.

Aditya-L1’s Mission Objectives

The Aditya-L1 spacecraft, aptly named after the Hindi word for the sun, is poised to become India’s first space-based solar probe. Its primary objective? To unravel the secrets of solar winds, which not only play a role in earthly disturbances but also manifest as the captivating “auroras.” Beyond immediate implications, the mission aims to provide invaluable data for comprehending the sun’s influence on our planet’s climate patterns.

Recent findings from the European Space Agency/NASA Solar Orbiter indicate the detection of sporadic jets of charged particles from the sun’s outer atmosphere, the corona. These revelations hint at a potential correlation with solar wind origins, an area where Aditya-L1 may contribute groundbreaking insights.

The Journey to Uncover Solar Secrets

The Aditya-L1 spacecraft will embark on its journey hitching a ride atop India’s robust Polar Satellite Launch Vehicle (PSLV). Over the course of approximately four months, it will traverse an astonishing distance of 1.5 million kilometers, all to scrutinize the sun’s ethereal atmosphere.

To optimize its position for observations, Aditya-L1 will rendezvous with one of the Lagrange Points in space. These unique spots, named after the pioneering mathematician Joseph-Louis Lagrange, maintain a delicate gravitational equilibrium, effectively reducing the spacecraft’s fuel consumption.

Mission Costs and India’s Thriving Space Industry

While the official cost figures remain undisclosed, the government allocated approximately $46 million for the Aditya-L1 mission in 2019. ISRO’s reputation for cost-effective space engineering positions India’s now-privatized space industry for global recognition.

For context, the Chandrayaan-3 moon mission, celebrated for its lunar south pole landing, operated on a budget of around $75 million.

Scientific Aims and Payloads

At its core, Aditya-L1 seeks an in-depth comprehension of our closest star, delving into its radiation, heat, particle flows, and magnetic fields and their effects on Earth. The mission’s payloads are tailored to explore the sun’s upper atmospheric layers, namely the chromosphere and corona.

Of particular intrigue is the mission’s potential to solve the long-standing mystery of why the sun’s corona, despite its faint appearance, reaches temperatures of a million degrees Celsius, far exceeding the sun’s surface temperature of about 5,500 degrees Celsius. Additionally, Aditya-L1 will shed light on the acceleration of solar particles, a key contributor to solar winds.

Payload Overview

Visible Emission Line Coronagraph (VLEC):

Developed by the Indian Institute of Astrophysics, this payload will capture the solar corona’s images, down to 1.05 times the solar radius, surpassing previous capabilities.

Solar Ultraviolet Imaging Telescope (SUIT):

Designed by the Inter University Centre for Astronomy and Astrophysics (IUCAA), this instrument will provide insights into variations in solar energy emissions.

Solar Low Energy X-ray Spectrometer (SoLEXS) and High Energy L1 Orbiting X-ray Spectrometer (HEL1OS):

Developed by the UR Rao Satellite Centre, these instruments will be dedicated to studying X-ray flares.

Aditya Solar wind Particle EXperiment (ASPEX) and Plasma Analyser Package for Aditya (PAPA):

Crafted to investigate the solar wind and energetic ions, ASPEX and PAPA have been developed by ISRO’s Physical Research Laboratory and the Space Physics Laboratory of ISRO’s Vikram Sarabhai Space Centre, respectively.

As we await the dawn of Aditya-L1‘s mission, the prospect of unveiling the sun’s mysteries beckons with unprecedented anticipation, offering not only scientific revelations but a testament to India’s prowess in the realm of space exploration.

What is the mission of Aditya-L1?

The Indian orbit Research Organization (ISRO) launched the Aditya-L1 mission into orbit with the goal of studying the Sun. Its main goal is to examine the corona, the Sun’s outermost layer, and research its dynamics and other solar activities.

When was Aditya-L1 mission launched?

the Aditya-L1. Scheduled for liftoff on September 2, this mission promises to shed light on the sun’s enigmatic atmosphere, paving the way for groundbreaking discoveries.

Where will Aditya-L1 launch?

The Satish Dhawan Space Centre (SDSC) on Sriharikota Island, Andhra Pradesh, India, is anticipated to serve as the launch site for the Aditya-L1 mission.

Who invented Aditya-L1?

The Indian Space Research Organisation (ISRO) and a group of scientists and engineers under the direction of ISRO designed the space mission known as Aditya-L1. It is credited to the corporation as a whole rather than a single creator.

Will Aditya-L1 land on the Sun?

Aditya-L1 won’t touch down on the Sun, no. In order to observe the Sun’s corona and other solar phenomena, it will be sent into a safe orbit around the Sun.

Which space mission was launched in 1977?

NASA launched the Voyager 1 and 2 spacecraft in 1977. These missions’ main objective was to learn more about our solar system’s outer planets, such as Jupiter and Saturn.

Which was the first satellite mission launched by ISRO?

The ISRO’s first satellite mission was dubbed “Aryabhata.” On April 19, 1975, it was launched from the Russian launch facility Kapustin Yar utilizing a Kosmos-3M launch vehicle.

Which is the first ISRO space mission?

The Rohini Satellite RS-1 was the ISRO’s first space mission, and it was launched on July 18, 1980. As an autonomous space agency, it signaled India’s entrance into the space era.

When was the PSLV C45 mission launched?

On April 1, 2019, ISRO launched the PSLV-C45 mission. The EMISAT electronic intelligence satellite was one of the 29 satellites it sent into orbit.

Why did Chandrayaan-2 fail?

While Chandrayaan-2 did not completely fail, there were difficulties during the mission. Due to a breakdown in connection with mission control, the Vikram lander, which was a component of Chandrayaan-2, was unable to perform a gentle landing on the Moon’s surface in September 2019. However, Chandrayaan-2′s orbiter component continues to circle the Moon and collect useful data. ISRO is still looking into the precise cause of the Vikram lander’s failure.
