India's Solar Observation Mission, named Aditya-L1, is set to be launched on September 2nd: Detailed Info on India's Initial Spacecraft for Solar Study
India's inaugural solar observation mission, the Aditya-L1, is preparing for takeoff on September 2, at 11:50 AM IST. The mission, aboard the PSLV XL spacecraft, will blast off from the Satish Dhawan Space Centre, Sriharikota, the same launch site that facilitated the successful launch of Chandrayaan-3.
Upon launch, the PSLV XL will traverse to the Lagrange Point (L1), though it will first stop at a Low Earth Orbit before propelling itself to L1. While in transit, the spacecraft will disengage from Earth's gravitational pull, embarking on a cruise phase and, subsequently, a large circular orbit encircling L1. In total, the mission from launch to L1 will take approximately four months.
ISRO's official website outlines that Aditya-L1's objectives include:
- Investigation of the dynamics of the solar upper atmosphere (chromosphere and corona)
- Examination of chromospheric and coronal heating, plasma initiated at the Sun, and flare incitement
- Monitoring of solar in-situ particles to study particle dynamics
- Detailed analysis of the physics of the solar corona, its heating method, and coronal loops' plasma parameters
- Collaborative efforts to understand CME drivers, the sequence leading to solar eruptive events, and magnetic field measurements in the solar corona
- Contributions to space weather forecasting, providing crucial data for predicting space weather events that may perturb satellite communications, navigation systems, and power grids on Earth
The mission seeks to bolster our comprehension of solar processes and help mitigate risks posed by space weather to Earth's technological infrastructure.
Reports indicate that the mission is projected to cost approximately ₹378 crore, although ISRO has yet to reveal the total budget for the mission. For further insights into ISRO's remarkable achievements, readers may refer to our article, "Taking a look at ISRO's greatest achievements."
