Aditya-L1’s Journey to Study the Sun
The Polar Satellite Launch Vehicle (PSLV) carried the Aditya-L1 on board, marking the 59th flight of this trusted launch vehicle. The liftoff occurred at 11:50 am from the Satish Dhawan Space Centre in Sriharikota. After a journey of approximately 63 minutes, the PSLV separated from the satellite, sending the Aditya-L1 spacecraft into a highly eccentric orbit around Earth at 12:53 pm. This launch was one of ISRO’s recent lengthiest missions for the PSLV.
Following the launch, Aditya-L1 will orbit Earth for 16 days, undergoing five manoeuvres to acquire the necessary velocity for its extended journey towards the sun. It will embark on a 110-day trajectory to reach the L1 Lagrange point, located approximately 1.5 million km from Earth and between the Earth and the Sun.
Mission Objectives and Payloads
Aditya-L1’s mission objectives are diverse and include studying phenomena such as coronal heating, coronal mass ejection, pre-flare and flare activities, dynamics of space weather, and particle and field propagation. The spacecraft is equipped with seven payloads, each designed to provide essential data for these research goals:
- Visible Emission Line Coronagraph (VELC)
- Solar Ultraviolet Imaging Telescope (SUIT)
- Solar Low Energy X-ray Spectrometer (SoLEXS)
- High Energy L1 Orbiting X-ray Spectrometer (HEL1OS)
- Aditya Solar Wind Particle Experiment (ASPEX)
- Plasma Analyser Package For Aditya (PAPA)
- Advanced Tri-axial High-Resolution Digital Magnetometers
These payloads will gather critical information about our Sun and its various processes, enhancing our understanding of space weather and solar phenomena.
Leaders’ Words: Prime Minister Narendra Modi & Minister Jitendra Singh
Indian Prime Minister Narendra Modi celebrated the successful launch on social media, highlighting the tireless efforts of India’s scientists and engineers at ISRO. Union Minister of State for Science & Technology, Jitendra Singh, also lauded the achievement, emphasising its significance globally.
With Aditya-L1 now on its path towards the L1 point and a mission lifespan of five years, India’s scientific community anticipates groundbreaking insights into the mysteries of our Sun.
Key Takeaways!
The successful launch of India’s Aditya-L1 solar observatory mission represents a significant leap forward in the nation’s space exploration efforts. As the spacecraft embarks on its mission to study the Sun from its unique vantage point, it promises to unravel some of the solar system’s most intriguing mysteries. India’s continued dedication to space research underscores its commitment to advancing scientific knowledge for the benefit of all humanity.
