In a recent development, the Indian Space Research Organization (ISRO) has achieved a significant milestone with its Chandrayaan-3 Mission by successfully landing on the moon’s south pole. While the Chandrayaan-3 Mission continues to unfold with its potential discoveries, ISRO has turned its attention to a new endeavor, its inaugural solar mission named Aditya-L1. Today, ISRO has revealed the launch details for the Aditya-L1 mission, marking an exciting step forward in India’s space exploration journey.
Scheduled Launch of Aditya-L1 Sun Mission
ISRO, through an official announcement on its platform (formerly Twitter), has disclosed that the Aditya-L1, India’s first solar observatory mission, is set to launch on September 2, 2023. The launch will take place from the Satish Dhawan Space Center SHAR (SDSC-SHAR) in Sriharikota, utilizing ISRO’s PSLV XL rocket. The liftoff is planned for 11:50 AM IST. This launch date aligns with the tentative timeline previously shared by ISRO Chairman S Somanath with the media agency ANI.
The mission objective involves placing the Aditya-L1 into a halo orbit around the Sun-Earth Lagrangian point 1 (L1), positioned around 1.5 million kilometers from Earth. The entire journey is expected to span about four months. During this time, ISRO will delve into the study of the Sun’s outermost layer, known as the Corona, and conduct real-time analysis of particles and fields to gain insights into the impacts of solar activities on space weather.
The Launch Process
The Aditya-L1 satellite will initially be transported by the PSLV XL rocket to a Low Earth Orbit. Following this, the satellite will venture beyond Earth’s gravitational Sphere of Influence (SOI) using its onboard propulsion to position itself at the designated L1 point.
Scientific Goals of the Aditya-L1 Mission
The Aditya-L1 spacecraft is equipped with seven distinct payloads designed to analyze the photosphere, chromosphere, and corona of the Sun using electromagnetic, particle, and magnetic field detectors. The mission is aimed at accomplishing several scientific objectives, including:
- Studying the upper atmospheric layers, such as the Chromosphere and the Corona of the Sun.
- Investigating phenomena like chromospheric and coronal heating, as well as the initiation of coronal mass ejections and flares.
- Unraveling the mysteries behind the heating mechanism of the solar corona.
- Collecting in-situ data about particles and plasma to enhance the understanding of particle dynamics originating from the Sun.
- Gathering diagnostics related to the coronal plasma, including factors like temperature, velocity, and density.
Distinctive Features of the Aditya-L1 Mission
As India’s inaugural solar mission, the Aditya-L1 holds several distinctive features that set it apart. Noteworthy aspects highlighted by ISRO include:
- The ability to spatially resolve the solar disk in the near UV band for the first time.
- Close study of Coronal Mass Ejections (CMEs) dynamics in proximity to the solar disk (approximately from 1.05 solar radius), contributing valuable insights into CME acceleration patterns.
- Incorporation of onboard intelligence to detect CMEs and solar flares, optimizing observation strategies and data volume.
- Utilization of multi-directional observation techniques to comprehend the anisotropy of solar wind.
