ISRO Successfully Launches 'Aditya L-1' Spacecraft from PSLV C-57 Rocket

In a historic achievement, ISRO successfully launched the 'Aditya L-1' spacecraft from the PSLV C-57 rocket, marking India's foray into solar mission exploration. Learn about this groundbreaking mission, its objectives, and the international context.

Introduction

On September 2, 2023, the Indian Space Research Organisation (ISRO) achieved a significant milestone in its space exploration endeavors. India successfully launched its first solar mission, 'Aditya L-1,' from the PSLV C-57 rocket at the Satish Dhawan Space Center in Sriharikota. This historic event positions India as the third country globally, after Europe and America, to embark on a mission dedicated to studying the Sun's corona.

Meet the Visionaries Behind Aditya L-1

Nigar Shaji, the project director of the Aditya L-1 mission, spearheaded this ambitious project. The Aditya-L1 spacecraft, equipped with seven indigenous payloads weighing 1480 kg, is poised to observe various facets of the Sun. Its primary objectives include unraveling the mysteries of coronal heating, understanding solar wind acceleration, initiating coronal mass ejections, and monitoring near-Earth space weather and solar wind distribution.

Aditya L-1's Epic Journey

Aditya L-1 embarks on a remarkable journey, spanning 125 days, to reach its designated orbit. This spacecraft will be strategically positioned in a halo orbit around Lagrange point L-1, nestled between the Sun and the Earth. Located approximately 15 lakh kilometers away from Earth, this unique vantage point allows Aditya L-1 to observe the Sun's activities without interference. In this region of space, known as the region between the Earth and the Sun, a total of five Lagrange points exist.

To navigate this vast distance, Aditya L-1 relies on its Liquid Apogee Motor (LAM), a testament to ISRO's technical prowess. This mission marks the 59th flight of the PSLV and the 25th mission with the XL configuration. Hyderabad-based CNC Technologies has emerged as a pivotal partner in realizing ISRO's Aditya L1 mission, while former ISRO Chairman UR Rao played a crucial role in the mission's initial phases.

A Global Endeavor

India joins a select group of nations that have embarked on missions dedicated to solar exploration. Japan's space agency, JAXA, initiated solar studies in 1981 with the launch of the first satellite, Hinotori (ASTRO-A), aimed at studying solar flares. Meanwhile, NASA, in collaboration with the European Space Agency (ESA) and JAXA, launched the SOHO mission in 1995. NASA further bolstered solar exploration with the launch of the Parker Solar Probe in 2018, becoming the first spacecraft to 'touch' the Sun.

The European Space Agency managed the Ulysses mission in 1990, focused on studying the environment above and below the Sun's poles. ESA continues to lead the way in solar exploration with upcoming missions like Proba-3 and Smile set to launch in 2024 and 2025.

China has also made significant strides, with the Chinese Academy of Sciences (CAS) launching the Advanced Space-Based Solar Observatory (ASO-S) 'Kuafu-1' in October 2022.
